Heald Frames Toyota 710 W=190

Product Description:

• This carbon fiber shock-absorbing heald frame is a high-performance shedding component specially developed for Toyota 710 190cm wide high-speed air-jet looms. It matches DRC10 series electronic dobby drives and supports continuous weaving at speeds over 1000 RPM, equipped with standard rail slots for C331 heald wires.
  The core design adopts a dual optimized structure: full-length carbon fiber lamination on upper & lower staves plus integrated shock-absorbing strips, with uniform 163mm stave width. Carbon fiber laminate greatly enhances bending rigidity, while shock-absorbing strips buffer impact from high-speed reciprocating movement, thoroughly solving three major problems: frame vibration, beam bending and fatigue deformation under ultra-high speed conditions.
  The main frame is integrally extruded from high-strength aerospace-grade aluminum alloy, realizing lightweight weight and structural rigidity simultaneously. Carbon fiber sheets are fully laminated on top and bottom edges, with built-in shock-absorbing strips to cut operating noise and suppress vibration transmission to the dobby unit.
  The heald wire rail is made of integrally stamped stainless steel with precision slots, perfectly compatible with C331 healds. Smooth burr-free surface ensures unobstructed wire sliding, resisting rust and abrasion during long-term non-stop production. All hanging holes and connection dimensions are 1:1 duplicated to Toyota original standard, allowing direct replacement without loom or dobby modification and commissioning.
  Designed for high-speed production lines of light chemical fiber and high-density poplin fabrics, it maintains stable shedding stroke above 1000 RPM, greatly reducing weaving defects including warp breakage, density bar and weft skew. It is a premium upgrade spare part for speed improvement renovation and daily maintenance of Toyota 710 looms.

Features:

• Carbon fiber laminated staves + full-length shock-absorbing strips: 163mm wide beams reinforced by carbon fiber plus built-in buffer strips, zero obvious vibration and anti-deformation at speed over 1000 RPM with excellent noise reduction.
  1:1 precise original compatibility: Fully fit Toyota 710 loom, DRC10 dobby drive and C331 heald wires, ready to use after installation without extra equipment adjustment.
  Lightweight high-strength composite material: Aerospace aluminum base laminated with carbon fiber, lighter weight and superior anti-fatigue bending resistance than ordinary all-aluminum frames, greatly extended service life.
  Precision stainless steel heald rails: Integral slotted forming, wear & rust resistant, avoid warp breakage and fabric defects caused by stuck heald wires.
  Special structure for ultra-high speed conditions: Optimized for weaving speed above 1000 RPM, restrain vibration transmission and protect dobby drive unit to reduce overall loom wear.
  Standard protective packing: Custom wooden case of 2100*800mm with built-in wooden positioning blocks, prevent scratch, extrusion and deformation during long-distance transportation.

Technical Parameters:

Applications:

• Heald frame is exclusively compatible with Toyota 710 190cm width air-jet looms and DRC10 electronic dobby drive system, applicable to continuous high-speed production lines over 1000 RPM, matched with C331 heald wires.
  It is mainly used for high-speed weaving of light chemical fiber fabrics, high-density poplin, stretch cloth and home textile plain fabrics. Carbon fiber reinforced beams and shock-absorbing strips effectively suppress high-speed reciprocating vibration, stabilize shedding timing and stroke, and greatly reduce common weaving defects such as warp breakage, density bar and weft skew, improving fabric yield under ultra-high speed production.
  Application scenarios include new loom assembly, speed-up renovation of old Toyota 710 looms, upgrade replacement of ordinary aluminum frames, bulk spare parts purchase for annual equipment overhaul. It suits large textile factories with 24-hour non-stop high-speed mass production. Compared with traditional non-carbon-fiber aluminum frames, it significantly cuts equipment downtime frequency and comprehensive operation & maintenance costs.

Support and Services:

• Accurate loom matching verification: Check compatibility according to model LV-ZA-277-163 Carbon-331C, Toyota 710 loom and 190cm width to avoid wrong spare part purchase.
  Installation and dobby commissioning guidance: Provide bilingual installation manual to guide DRC10 dobby hanging positioning, heald threading and shock absorption structure inspection, troubleshooting high-speed vibration and wire jamming faults.
  1-year official warranty: Free replacement for manufacturing defects including beam delamination, aluminum frame crack and rail rust abrasion caused by normal operation within warranty period; damage from man-made impact or over-speed overload is excluded from warranty.
  In-stock bulk supply & customization: Sufficient permanent stock for standard 190cm Toyota 710 frames with fast full-container delivery for export orders; custom frames with different stave width, loom width and drive connectors are available on request.
  One-stop complete consumable supply: We can supply matching C331 heald wires, DRC10 dobby spare parts, roller coverings and all full-set Toyota loom textile accessories together.
  7×24 online technical support: Quick response to on-site workshop faults such as high-speed weaving vibration, shedding offset and frame abrasion to minimize production downtime loss.

Packing and Shipping:

• Each heald frame is fully wrapped with thick pearl cotton on upper/lower beams, rails and corners, covered with film to prevent scratch and rust. Solid wood positioning blocks are installed inside the wooden case to fix the frame firmly and avoid deformation and collision from extrusion and shaking during transit. The whole set is packed into custom solid wooden case sized 2100*800mm, reinforced with steel belts for compression and drop resistance, suitable for overland and sea long-length cargo logistics.
  Compatible loom Toyota 710, width 190cm, quantity and moisture/shock protection marks are clearly printed on the wooden box exterior for warehouse stocktaking and workshop picking.
  In-stock orders will be packed and shipped within 48 hours, domestic full-truck logistics direct delivery to textile factories; export orders support sea and air freight for over-length cargo with full traceable logistics information, ensuring frames delivered intact without scratch or deformation. Neutral unbranded wooden cases and customer OEM customized outer packaging are available.

FAQ:

• Q1: Can this heald frame directly replace original Toyota 710 frame? Will it vibrate and deform when running above 1000 RPM?
  A: Direct damage-free replacement is supported, all hanging holes and connection dimensions are fully consistent with OEM parts. The 163mm wide carbon fiber beams plus full-length shock-absorbing strips are specially engineered for speed over 1000 RPM, no obvious vibration or bending deformation after long-term continuous weaving.
  Q2: Which heald wire and dobby drive unit does this frame match?
  A: It only fits C331 heald wires and DRC10 electronic dobby drive unit, exclusively for 190cm width Toyota 710 air-jet loom.
  Q3: What failures are covered by the 1-year warranty? What damages are not covered?
  A: The warranty covers manufacturing defects under normal weaving conditions including carbon fiber beam delamination, aluminum profile crack, rail rust abrasion and factory dimensional deviation. Damages caused by man-made impact, long-term overload operation over 1000 RPM, acid & alkali corrosion and self-cutting frame modification are not covered by warranty.
