Thread Transport
Weft placement in modern linen weaving is executed by flexible or rigid metal bands that grip the yarn and carry it across the loom. Through rapier filling insertion, the loom delivers the delicate flax thread through the warp shed with mechanical precision. This method is highly effective for thick or uneven yarns that would fail on pneumatic systems.
Mechanical Transfer
The mechanism consists of a giver rapier that collects the yarn from the supply package and carries it to the center of the warp shed, where a taker rapier receives it and completes the journey to the opposite side. This positive transfer provides exceptional control over the weft tension, which is particularly beneficial for linen yarns because of their low elasticity and tendency to break under sudden stress. Because the weft is mechanically held throughout the insertion cycle, the loom can handle a wide variety of yarn counts and structures without requiring complex nozzle adjustments.
Production Flexibility
Weaving mills rely on this high level of control to produce dense, heavy linen fabrics with fewer loom stops. While slower than air-jet methods, rapier filling insertion remains the preferred choice for premium linen weavers who require absolute reliability when processing expensive combed flax yarns.
