Plastic Leno Heddle 13 Yellow With M Leno Doup Loom Leno System Spare Part

Product Description:

• This product Plastic Leno Heddle 13 Yellow With M Leno Doup is a special consumable for loom leno mechanism. The set consists of Type 13 yellow engineering plastic leno heddle and 0.5mm thick M-shaped metal leno doup, which can serve as direct replacement for conventional F Leno Doup assembly.
  The leno heddle is integrally injection molded from high-strength wear-resistant engineering plastic with integrated clip structure on both ends for easy assembly and disassembly. The matched M-type metal leno doup receives polishing treatment, featuring balanced toughness and smooth surface to effectively reduce yarn fuzzing and warp breakage caused by friction during weaving. Mounting dimensions and slot specifications are designed according to universal leno mechanism standards. No modification to leno bracket is required when replacing F-type leno components, and production can be launched after simple commissioning.
  The plastic body delivers excellent anti-fatigue performance, resisting brittle fracture and deformation under long-term high-speed reciprocating movement. The wear-resistant and smooth metal leno doup steadily restricts selvedge warp yarn to interlace and form firm locked selvedge, preventing unraveling of grey fabric edges. It is widely compatible with various weaving machines fitted with leno devices, acting as standard replacement parts for selvedge weaving process.

Features:

• Lightweight carbon fiber lever: Light weight with excellent rigidity, reduce high-speed transmission inertia and suppress vibration of leno mechanism.
  Composite stainless steel bushings on both ends: Reinforce hinge points for wear resistance, avoid carbon fiber hole abrasion, enlargement and cracking.
  Standardized hole machining: All hinge dimensions interchangeable with complete lever arm assembly.
  Integral carbon fiber plate: Excellent anti-fatigue performance, resistant to deformation and fracture under long-term cyclic load.
  Pre-fitted metal bushings for direct installation, reducing on-site processing work.
  Adapt to continuous textile production: Dust and impact resistant for 24-hour non-stop high-speed weaving.

Technical Parameters:

Applications:

• This set of plastic leno heddle and M leno doup is applied on air-jet looms and rapier looms equipped with leno mechanism to complete selvedge interlocking weaving.
  It is suitable for production of plain fabric, twill fabric, home textile fabric, industrial base fabric and other grey fabrics requiring reinforced selvedge. It firmly locks selvedge yarns and prevents edge unraveling during fabric finishing. This part is suitable for daily wear replacement and bulk spare stock of loom leno systems in textile mills, adapting to 24-hour non-stop high-speed production lines and steadily improving selvedge forming quality.

Support and Services:

• Compatibility verification: Check specification of loom leno mechanism to confirm the part can replace original F-type leno assembly and avoid wrong purchase.
  Installation & commissioning guidance: Provide operation guide for clip mounting and doup embedding, troubleshoot doup falling off and uneven selvedge interlacing.
  1-year official warranty: Free replacement for manufacturing defects such as inherent plastic heddle crack and factory deformed doup under normal weaving conditions. Natural wear caused by hard yarn friction and long-term over-speed overload is excluded.
  Bulk in-stock supply: Support bulk delivery of complete sets to meet daily stocking demand of factories.
  One-stop procurement for textile loom spare parts, various loom wear parts can be ordered together.
  Online technical support to quickly handle on-site faults such as abnormal selvedge weaving and displaced leno doup.

Packing and Shipping:

• Plastic leno heddles and metal doups are arranged together in a compact stack and wrapped with bubble film for overall protection, preventing scratch damage, friction and deformation during transit. The wrapped unit is then placed into a thickened outer carton filled with cushioning material to avoid plastic part fracture, metal doup bending and pressure damage caused by stacking or extrusion.
  Labels are applied on the outer packaging to indicate part name, item number, code and quantity for easy warehouse stocktaking, incoming inspection and workshop picking.
  Regular orders will be shipped within 48 hours. Export orders support full logistics tracking, and neutral unbranded packaging is available.

FAQ:

• Q1:Do I need to adjust leno mechanism stroke when replacing F-type assembly with M Leno Doup assembly?
  A: Stroke adjustment is not required, it can be directly installed as replacement. Simply observe selvedge forming after initial installation, slight fine-tuning can achieve stable weaving performance if needed.

  Q2: What is the main reason for frequent breakage of plastic leno heddles?
  A: It is mostly caused by offset leno stroke, continuous friction from yarn flyings and long-term loom over-speed. Calibrate stroke during installation, clean yarn impurities regularly and avoid prolonged overload production.

  Q3: Can slightly bent M-type metal leno doup continue to be used?
  A: Continued use is not recommended. Deformed doup will change yarn guiding path and easily lead to selvedge texture unevenness and density bar defects, replacement with new part is recommended.
