\"EverRing spinning remains the global gold standard for producing high-quality spun yarn, and within a modern ring spinning frame \u2014 whether it’s a Rieter G 38, a Toyota RX300, or a legacy machine rebuilt for performance \u2014 the drive chain is the heartbeat of the entire drafting and spindle system. When that chain falters, spindles miss their rhythm, yarn breaks multiply, and efficiency numbers collapse fast. After eighteen years working directly with textile machinery engineers and maintenance managers across the UK and Europe, I’ve seen the same preventable failure repeat itself with alarming regularity: the wrong chain specification deployed in a high-cycle, high-tension drive application.<\/p>\n

Leaf chain \u2014 also known as lacing chain or balance chain \u2014 is a flat, pin-and-plate construction that handles tensile loads with extraordinary resilience. Unlike roller chain, which relies on a rolling element to manage contact stress, leaf chain distributes load across stacked interleaved link plates, giving it a substantially higher tensile-to-weight ratio and far better fatigue performance under oscillating or shock-load conditions. In a ring spinning frame, where the main shaft drive operates continuously at speeds between 12,000 and 25,000 rpm and the traveller-spindle system experiences complex vibration profiles, that combination of properties is not a nice-to-have \u2014 it is a fundamental engineering requirement.<\/p>\n<\/div>\n<\/div>\n

What Exactly Is a Leaf Chain \u2014 and Why Does It Matter in Textile Drive Systems?<\/h2>\n
\n
\n

A leaf chain is a purely structural chain \u2014 it transmits tensile force without wrapping around a sprocket in the conventional sense. Its construction is beautifully simple: alternating rows of inner and outer link plates, stacked in defined lacing patterns (AL or BL series), pinned together with precision-ground pins and secured by press-fit or rivet-peened heads. There are no rollers, no bushings, and no side-plate offsets. Every component exists to carry load, not to manage friction against a sprocket tooth.<\/p>\n

In a ring spinning frame, leaf chains are commonly deployed in the bobbin rail (ring rail) lifting mechanism \u2014 a system that raises and lowers the ring rail at precise intervals to build a wound package with uniform cop geometry. This motion must be smooth, backlash-free, and absolutely repeatable across a machine that may run twenty-four hours a day, seven days a week, for operational periods of twelve months or longer without a full strip-down. The fatigue demands are severe. A poorly-specified standard roller chain will develop play in the pin-plate interface within weeks; that play translates directly into ring rail oscillation, uneven winding tension, and catastrophic yarn quality degradation.<\/p>\n

Beyond the ring rail drive, leaf chain also appears in the traveller-lift cam linkages, tension apron adjustment mechanisms, and \u2014 in older architectures \u2014 the main tangential belt tensioning systems. Each application demands a chain that holds its pitch dimension under sustained load, resists side flexure from guide pulleys, and tolerates the fine-particle contamination environment that is endemic to spinning rooms: fibre dust, lubricant mist, and occasional condensate from humidity control systems.<\/p>\n<\/div>\n

Why Leaf Chain Outperforms Roller Chain in Ring Spinning Frame Environments<\/h2>\n

\"LeafThe operating environment inside a modern spinning room is more punishing than it looks from the outside. Fibre dust penetrates every gap in roller chain bushings, embedding abrasive particles that grind the rolling contact surfaces from the inside out. Temperature cycles between morning start-up and full-production heat cause micro-expansion in roller-bushing clearances that accumulate into measurable pitch elongation within a single production season. Humidity control \u2014 non-negotiable for cotton and wool ring spinning \u2014 adds a corrosion vector that accelerates oxidative wear on unprotected carbon steel surfaces.<\/p>\n

Leaf chain sidesteps these failure modes entirely. The absence of bushings and rollers means no hollow cavity for fibre dust to pack into. The solid plate-on-pin interface, precision-ground to sub-micron tolerances, develops a work-hardened contact patch over the first few hundred hours of operation that actually improves wear resistance over time rather than degrading. For spinning frame applications in Lancashire, Yorkshire, and across UK textile counties, where machines often run wet-spun flax or high-micronaire cotton requiring aggressive humidity management, the stainless steel and zinc-nickel-plated variants have consistently delivered service lives two to four times longer than equivalent roller chain installations.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
<\/div>\n

Six Engineering Advantages That Make a Measurable Difference<\/h2>\n
\n
\n
\u26a1<\/span><\/div>\n

Superior Tensile Fatigue Life<\/h3>\n

The multi-plate lacing distributes cyclic tensile loads across a far greater cross-sectional area than any equivalent roller chain. Under the stop-start load profiles of a ring rail lifting mechanism \u2014 which can complete 3,000+ oscillation cycles per spindle per shift \u2014 this structural advantage translates into pin and plate fatigue lives measured in tens of millions of cycles rather than single-digit millions. Independent SN-curve testing at our accredited laboratory shows BL-series chains surviving 50 million reversing load cycles at 60% of minimum breaking load without measurable pitch elongation.<\/p>\n<\/div>\n

\n
\u2699<\/span><\/div>\n

Dimensional Pitch Stability<\/h3>\n

Ring rail position accuracy depends directly on chain pitch holding its tolerance across the full temperature and load operating envelope of the machine. Ever Power leaf chains are manufactured to pitch tolerances of \u00b10.02% of nominal pitch, verified by coordinate measuring machine (CMM) on every production batch. That precision matters enormously in ring spinning \u2014 a 0.5mm cumulative pitch error across a 3-metre rail travel can shift the winding traverse point by enough to create winding faults visible as banding in the finished fabric. Our customers in the West Yorkshire spinning sector consistently report zero pitch-related winding rejects after switching to our chains.<\/p>\n<\/div>\n

\n
\ud83d\udd12<\/span><\/div>\n

Corrosion & Contamination Resistance<\/h3>\n

Spinning rooms running natural fibres \u2014 cotton, wool, linen, silk \u2014 operate at relative humidity levels of 55\u201375% to prevent static build-up and fibre breakage. That atmospheric moisture, combined with the high-pH cleaning agents used during weekend machine washdowns, creates an aggressive corrosion environment for standard carbon steel chain. Our zinc-nickel electroplated finish provides 720 hours salt-spray resistance per ISO 9227, while the stainless steel variants are specified for the most demanding humid-room installations, particularly in facilities processing sea-island cotton or fine merino where even the slightest iron contamination can affect dyeing characteristics of the finished yarn.<\/p>\n<\/div>\n

\n
\ud83d\udcc8<\/span><\/div>\n

Low-Noise Operation<\/h3>\n

High-speed ring spinning frames are already acoustically challenging environments \u2014 spindle noise, drafting apron vibration, and traveller-on-ring friction all contribute to a broadband noise floor that can exceed 90 dB(A) in unoptimised installations. Chain drive noise that would be insignificant in a slower machine becomes a measurable contributor at 20,000+ rpm. The leaf chain’s flat plate-on-plate contact geometry generates a fundamentally lower-frequency and lower-amplitude vibration signature than the roller-on-sprocket tooth impact that characterises roller chain operation at speed. Maintenance engineers at our customer sites consistently note a subjective reduction in drive bay noise after leaf chain installation \u2014 confirmed by octave-band analysis showing a 3\u20135 dB reduction in the 630\u20131250 Hz range where chain drive noise typically peaks.<\/p>\n<\/div>\n

\n
\ud83d\udd27<\/span><\/div>\n

Simplified Lubrication Protocol<\/h3>\n

Roller chain systems in spinning frames require regular lubrication of multiple contact interfaces \u2014 the roller-bushing bore, the bushing-pin interface, and the plate-side surfaces \u2014 using lubricants that must be carefully matched to fibre type to avoid contamination of the drafted sliver. Leaf chain requires lubrication only at the pin-plate interface, reducing both lubricant consumption and the risk of over-application causing fibre contamination. Our factory-applied wax-based initial lubrication treatment, standard on all textile-series chains, extends the time to first re-lube to approximately 3,000 hours of operation under typical ring spinning conditions \u2014 a significant maintenance overhead reduction for facilities running continuous three-shift patterns.<\/p>\n<\/div>\n

\n
\ud83d\udee0<\/span><\/div>\n

Direct Drop-In Compatibility<\/h3>\n

Ever Power manufactures leaf chain to both AL (ANSI) and BL (BS\/ISO) dimensional standards, covering the full range of pitches and plate widths used across Rieter, Savio, Toyota, Zinser, and legacy Platt Brothers ring spinning machines. Matching a replacement chain to an existing machine is straightforward: provide the pitch, pin diameter, and inner plate width from your current chain or from the machine’s BOM, and we can cross-reference to the appropriate series within 24 hours. For non-standard or obsolete machines no longer supported by OEM spares \u2014 a significant challenge for UK mills still running 1990s-era equipment \u2014 we offer custom fabrication with matched dimensions and verified breaking loads, supplied with full material certification to BS EN 10204 3.1 standard.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n
<\/div>\n

Specific Application Zones in the Ring Spinning Frame<\/h2>\n

Understanding precisely where leaf chain is deployed \u2014 and why it works so well in each location \u2014 helps maintenance planners make the right specification choice and avoid the common error of using a single chain series across multiple functionally-distinct positions.<\/p>\n

\n
\n

<\/p>\n

\n
\n
Zone 01<\/div>\n

Ring Rail Lifting Drive<\/h3>\n<\/div>\n

The ring rail lift chain is arguably the most mechanically demanding position in the entire machine. It must synchronise the vertical reciprocation of the ring rail \u2014 which carries all spindle rings and associated hardware \u2014 with the traversing cam drive while maintaining sub-millimetre positional accuracy throughout a cop-building sequence that can run for 45\u201390 minutes before doffing. The chain operates under variable tension as the cam profile changes, experiences sharp load reversals at each traverse direction change, and must maintain pitch fidelity across the full rail travel length. AL422 and AL534 series chains are the workhorses here, specified for machines up to 1008 spindles per side.<\/p>\n<\/div>\n

<\/p>\n

\n
\n
Zone 02<\/div>\n

Top Arm Pressure & Apron Tensioning<\/h3>\n<\/div>\n

The drafting zone of a ring spinning frame applies controlled tension to the fibre bundle as it is attenuated from sliver to roving to yarn count. Top arm spring pressures and apron tension settings are typically adjusted once per spinning lot, but the adjustment mechanisms use short sections of leaf chain or flat link chain to transmit the adjuster’s torque into linear displacement. Backlash in this chain \u2014 even fractions of a millimetre \u2014 results in inconsistent nip pressures across the creel width, generating count variations (CSP errors) that only become visible during downstream quality testing. BL634 series chain, with its tighter plate tolerance and harder pin finish, is the standard specification for this application.<\/p>\n<\/div>\n<\/div>\n

Zone 03<\/div>\n

Doffing Trolley & Bobbin Transport<\/h3>\n<\/div>\n

Automated doffing systems and bobbin transport conveyors within the ring spinning section typically use heavier leaf chain in a flat-link conveyor configuration. The leaf chain here must handle shock loads from full bobbins dropping onto the transport deck, resist contamination from fibre waste that accumulates rapidly in conveyor channels, and maintain consistent speed synchronisation with the doffing arms to prevent bobbin collision. BL series chains with heavy phosphate surface treatment and extended-pitch configurations are standard for this application, operating at conveyor speeds of 0.5\u20132.0 m\/s and carrying aggregate loads of 80\u2013300 kg per metre of conveyor length.<\/p>\n<\/div>\n

\n
\n
Zone 04<\/div>\n

Main Drive & Tangential Belt Tensioner<\/h3>\n<\/div>\n

In ring spinning frames where the spindle drive uses a tangential flat belt running the full machine length, maintaining consistent belt tension across 800\u20131200 spindles requires a tensioning linkage that is both strong and backlash-free. Any compliance in the tensioning chain allows the belt tension to fluctuate with machine vibration, causing spindle speed variation and the resulting yarn count irregularity (unevenness U%). Leaf chain in the tensioner linkage \u2014 typically a short assembly of 15\u201330 links \u2014 provides the stiffness and load-holding capacity that prevents this mode of failure. Our AL series with solid-head pin ends and locking connectors are the preferred solution for this application, combining ease of length adjustment during belt change with zero-backlash force transmission.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Thornbury Spinning Ltd \u2014 32% Reduction in Drive-System Downtime<\/h3>\n

\"EverThornbury Spinning Ltd, a mid-size combed cotton producer operating from a 1960s-era mill building in Bradford, was running a fleet of 28 Toyota RX300 ring spinning frames fitted with the original roller chain ring rail drive systems. By 2023, their maintenance team was spending an average of 6.8 hours per machine per quarter on chain replacements, tension resets, and associated ring rail alignment work \u2014 a figure that translates to over 190 hours of annual drive-system maintenance across the fleet, with roughly 35 hours of that as unplanned emergency replacement during production runs.<\/p>\n

After evaluating options with our technical sales team, they completed a full fleet conversion to Ever Power AL534 leaf chains across all 28 machines during a single scheduled shutdown in January 2024. The AL534 was selected for its direct pitch compatibility with the Toyota RX300’s ring rail drive sprocket geometry and its superior fatigue life under the machine’s specific 18-minute cop-building cycle. Over the subsequent 12 months, Thornbury reported a 32% reduction in ring rail drive-related maintenance hours, zero unplanned chain replacements, and a measurable improvement in their first-quality yarn rate from 94.2% to 96.8% \u2014 attributed in part to more consistent ring rail traverse accuracy after the chain upgrade.<\/p>\n<\/div>\n

Materials, Manufacturing Principles, and Why They Matter<\/h2>\n
\n
\n

Every leaf chain begins as a strip of high-carbon or alloy steel \u2014 typically C60 or 20MnCr5 for standard grades, 316L austenitic stainless for corrosion-resistant variants. The strip is blanked under a progressive die to produce link plates with precisely-formed pin holes. Hole diameter tolerance is held to \u00b10.005 mm; any variance beyond this creates the inter-plate micro-play that is the primary initiator of fatigue crack growth in the link plate hoop stress zone. Following blanking, plates are heat-treated to a surface hardness of 54\u201358 HRC by either case-hardening (for alloy grades) or through-hardening (for carbon steel grades), then shot-blasted to remove decarburised surface layers and induce a compressive residual stress that significantly extends plate fatigue life under tensile loading.<\/p>\n

Pins are manufactured from higher-carbon alloy steel (typically 20CrMnTi or 42CrMo4), centreless-ground to a pin diameter tolerance of \u00b10.003 mm and surface-hardened to 58\u201362 HRC with a case depth of 0.4\u20130.8 mm depending on chain series. The critical interface between the pin outer diameter and the link plate hole is designed with an interference fit that is tight enough to prevent any relative rotation of plate on pin during normal operation \u2014 because pin rotation initiates fretting corrosion of the plate hole bore, which can reduce the effective plate cross-section by 15\u201320% within 500,000 load cycles. Our assembly press tooling maintains this interference fit within \u00b10.002 mm on every single link joint, verified by statistical process control with a minimum Cpk of 1.67 on the pin press-fit force curve.<\/p>\n

The assembled chain undergoes 100% breaking load proof testing at 50% of rated minimum tensile strength before shipping \u2014 a standard that exceeds the ISO 4347 requirement of batch-sample testing. For chains destined for UK customers under MRO or capital project supply agreements, we can provide EN 10204 3.1 material certificates, full heat treatment records, and dimensional inspection reports as standard. Third-party witnessed testing by Lloyd’s Register or Bureau Veritas is available on request for projects requiring elevated assurance levels.<\/p>\n<\/div>\n

How to Specify the Right Leaf Chain for Your Ring Spinning Frame<\/h2>\n

Getting the chain specification right the first time prevents costly repeat procurement and avoids the compatibility issues that arise when pitch, plate width, or attachment dimensions don’t match the existing hardware. The following four-parameter approach is what our application engineers use when assessing new UK customer machine requirements.<\/p>\n

\n
\n
01<\/div>\n

Identify Chain Pitch<\/h3>\n

Measure pin centre-to-centre distance on the existing chain using a vernier calliper across 10 links and divide by 10 for accurate pitch. Cross-reference against ANSI or BS\/ISO tables. If the pitch is non-standard, measure the sprocket tooth spacing instead \u2014 this gives the driven pitch, which must match the chain pitch for smooth engagement.<\/p>\n<\/div>\n

\n
02<\/div>\n

Determine Maximum Working Load<\/h3>\n

For the ring rail application, the maximum working load is the combined weight of the ring rail assembly plus the dynamic load factor from the traverse acceleration profile. A standard safety factor of 4:1 on minimum breaking load to maximum working load is appropriate for ring spinning drives with shock loading; increase to 6:1 for heavily shock-loaded doffing conveyor applications or machines that experience sudden emergency stops.<\/p>\n<\/div>\n

Select Lacing and Surface Finish<\/h3>\n

Match the lacing pattern (2\u00d72, 3\u00d73, 4\u00d74 etc.) to the required breaking load at the chosen pitch. Select surface finish based on environment: zinc-nickel for general humid spinning rooms; stainless for aggressive wet environments; self-colour with wax oil for dry enclosed drives. Always verify that the chosen finish is compatible with any lubricants already in the machine system.<\/p>\n<\/div>\n

Specify Length and End Fittings<\/h3>\n

Measure the required closed loop length or the travel distance for a linear chain application. Specify whether the chain requires clevis end fittings, threaded clevis pins, solid cotter-pin ends, or simple open-ended bulk supply. For ring rail applications, the chain length must be specified precisely \u2014 incorrect length requires shimming of the rail guide posts, which is time-consuming and introduces additional wear points. When in doubt, supply us with your machine model and serial number; we can often cross-reference our OEM documentation archive directly.<\/p>\n

Serving the United Kingdom Textile Machinery Market<\/h2>\n
\n
\n

The United Kingdom maintains a proud and commercially significant textile manufacturing heritage. From the worsted and woollen mills of West Yorkshire \u2014 Bradford, Halifax, Huddersfield, Dewsbury \u2014 to the cotton heritage facilities of Lancashire and Greater Manchester, and the linen and technical textile producers of Scotland and Northern Ireland, there remains a substantial and active base of ring spinning frame operators across the country. Many of these mills combine legacy machines from the 1980s and 1990s with newer frame installations, creating a mixed fleet maintenance challenge that requires a supplier capable of covering obsolete, legacy, and current-generation chain specifications from a single source.<\/p>\n

Ever Power supplies UK textile machinery operators both directly and through our established network of regional engineering distributors. UK-based accounts benefit from dedicated technical support from our European application engineering desk, with response times of under four hours during business hours for urgent technical queries. We hold safety stock of the most common textile-grade leaf chain<\/a> series in our UK partner warehouses, enabling same-day despatch for emergency maintenance requirements. For planned capital maintenance and replacement programmes, we work with plant engineers and procurement teams to create scheduled supply agreements that stabilise chain cost over rolling 12-month periods and guarantee stock availability. Whether you operate a single spinning frame or a fleet of 500, we can structure a supply arrangement that matches your operational rhythm and budget cycle.<\/p>\n<\/div>\n

What is the best leaf chain pitch and lacing pattern for a Rieter ring spinning frame ring rail lift mechanism in a UK cotton mill?<\/h3>\n<\/div>\n
\n

For Rieter G 35, G 38, and G 40 series frames operating on typical UK combed cotton counts (Ne 16\u201360), the AL534 series \u2014 15.875 mm pitch, 3\u00d74 lacing, alloy steel with zinc-nickel plate \u2014 is the most commonly recommended specification. This combination delivers a minimum breaking load of 22.2 kN and pitch fatigue life exceeding 40 million cycles at the ring rail working loads of 180\u2013350 kg typical for these machines. For machines running lighter ring rail assemblies, the AL422 (9.525 mm pitch, 2\u00d72) offers a more economical option with sufficient margin. Always confirm the actual ring rail assembly weight and drive sprocket pitch before finalising the specification.<\/p>\n<\/div>\n<\/div>\n

\n
\n

How much does a custom leaf chain for a ring spinning frame cost, and where can I get a supplier price or quote in the UK?<\/h3>\n<\/div>\n
\n

Leaf chain pricing for ring spinning frame applications varies significantly depending on pitch, lacing configuration, length, surface finish, and whether the chain is a standard or custom product. Standard stock grades typically range from approximately GBP 8\u201345 per metre depending on series and finish; custom or large-lacing configurations will be quoted on specification. The most reliable route to a price is to send your chain part number or machine model to our technical sales team at sales@leaf-chain.com \u2014 we respond to all UK enquiries with a firm quotation within 24 business hours, no obligation, no minimum order for pricing enquiries.<\/p>\n<\/div>\n<\/div>\n

How do I know when to replace the leaf chain on a Toyota ring spinning frame, and what are the signs of chain wear I should be looking for?<\/h3>\n<\/div>\n
\n

The primary wear indicator for leaf chain on a ring spinning frame ring rail is pitch elongation \u2014 measured as total extension of a reference gauge length compared to the nominal new dimension. ISO 4347 recommends replacement when elongation reaches 2% of gauge length for ring rail applications, though many textile maintenance engineers use a 1.5% threshold to maintain ring rail accuracy. Visible indicators to monitor at each monthly inspection include: side plate surface pitting or discolouration (indicating corrosion onset); lateral play between inner and outer plates exceeding 0.5 mm on a 30-link section (indicating pin wear); and audible irregularity in chain articulation during slow manual traverse (indicating link stiffness from contamination or lubricant breakdown). Replace the chain, not just the worn links \u2014 partial chain replacement creates a stiffness mismatch that accelerates wear on the new section.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Which type of leaf chain is suitable for wet spinning rooms running linen or flax on ring frames in Scotland or Northern Ireland?<\/h3>\n<\/div>\n
\n

Wet spinning of linen and flax creates an exceptionally harsh chain environment \u2014 relative humidity regularly exceeds 80% RH, water is directly applied to the fibre ahead of the drafting zone, and the alkaline nature of the sizing and preparation chemicals accelerates corrosion of standard carbon steel. For these applications, we strongly recommend 316L austenitic stainless steel leaf chain (our AL series SS variants) as the primary specification. These provide corrosion resistance to chloride-containing atmospheres, resist the pH range from 6 to 12 typically encountered in wet spinning preparation areas, and avoid any iron contamination risk to the fibre. Where the cost premium of full stainless is not justified \u2014 for example in conveyor applications at the back of the wet spinning section \u2014 the heavy zinc phosphate + E-coat variants of our BL carbon steel chains offer a cost-effective alternative with 2\u20133 years expected service life in this environment.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Can I get a custom-length leaf chain with specific end fittings for a legacy Platt Brothers ring spinning frame no longer supported by original spare parts suppliers?<\/h3>\n<\/div>\n
\n

Yes \u2014 this is one of our core service propositions for the UK market, where a meaningful proportion of operating ring spinning frames are legacy Platt Brothers, Dobson and Barlow, or Howard and Bullough machines that are no longer supported by OEM spares channels. We maintain a cross-reference archive of historical UK textile machinery chain specifications, and for machines not covered by our archive, we can reverse-engineer the chain specification from a physical sample of the existing chain, from your maintenance records, or from machine drawings. Custom-length assemblies with closed-loop dimensions, clevis ends, drilled attachment plates, or matched connection links are manufactured to order with a 10\u201320 working day lead time. Where the original pin diameter or plate width falls outside standard series \u2014 which is common on 1960s\u20131980s UK-built spinning frames \u2014 we can manufacture tooling to produce matching dimensions. Contact us with your machine nameplate details and a brief description of the chain application for an initial feasibility assessment at no charge.<\/p>\n<\/div>\n<\/div>\n

\n
\n

What is the difference between AL-series and BL-series leaf chain, and which should I choose for a ring spinning frame application with high shock loading?<\/h3>\n<\/div>\n
\n

The AL series (ANSI standard) and BL series (British Standard \/ ISO standard) differ primarily in dimensional conventions \u2014 pin diameters, plate thicknesses, and inner width tolerances \u2014 rather than fundamental performance characteristics, since both series are manufactured to similar material and hardness specifications. The important distinction is application-level: AL series chains offer a more refined plate geometry that favours higher-cycle, lower-shock applications such as ring rail lift mechanisms; BL series chains, with their heavier plate sections and larger pin diameters at equivalent pitches, are better suited to applications involving substantial shock loading, such as bobbin transport conveyors with heavy loading impacts or emergency-stop ring rails. For a high shock loading scenario on a ring spinning frame, specify BL series, target a safety factor of 6:1 on breaking load to maximum working load, and select alloy steel (heat-treated and shot-peened) over standard carbon steel for maximum fatigue life. Our technical team can review your specific shock load profile and recommend the exact series and lacing pattern if you can provide the machine’s ring rail weight and traverse acceleration rate.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
