LB851 Water Jet Loom

The LB851 heavy water jet loom weaves demanding ultra-fine, blackout, and airbag fabrics at high speeds (1200 RPM) with exceptional stability. It features waterproofing upgrades and supports multiple weft/shedding devices.

The LB851 is a high-density, ultrafine heavy water jet loom engineered for demanding fabrics. It excels in weaving ultra-fine denier, ultra-high density blackout, and airbag fabrics, offering broad versatility across fabric types. Enhanced weather resistance further expands its application range.

Performance is exceptional, reaching speeds up to 1200 RPM while maintaining high efficiency and operational stability. It handles extreme densities, achieving up to 205 threads per inch (80 shuttles/cm) for fabrics like 75D.

Key mechanical innovations ensure fabric integrity and loom stability:

  • Short-stroke beating minimizes reed damage to delicate fabrics.

  • An eccentric shaft reduces beating vibration.

  • Increased longitudinal rack support and a 40mm lowered center of gravity enhance structural rigidity.

  • Reduced fabric take-up roller distance decreases springback and improves textile export stability.

  • A stable negative-slack warp beam tension system ensures consistent yarn control.

The LB851 offers versatile configuration: It supports 1-4 color crank openings or crank 6 linkage, and can be equipped with machine or electronic weft storage devices, multi-jet capabilities, and cam or dobby shedding motions.
