How to determine the rear beam position of the rapier loom?
The height of the rear beam is equal to that of the thorax, and the tension of the upper and lower warp yarns is the same. Rapier loom high speed, tension, cloth width, and other tension sheds will appear reed road and the shadow. Affect the appearance of the fabric quality and style.
Weaving coarse yarn fabric after the back to move to increase the warp on the back beam of the surrounding angle, so that the tension to maintain uniform, fabric straight and crisp, but the back of the beam to move too much, the blockers work inconvenient.
Weaving fine yarn high-density fabric when the beam forward, warp tension increases, is conducive to open the shed, reducing the warp beam on the back beam of the enclosing angle, reduce friction, reduce the warp break.
Usually in the weaving of special yarn fabric, the rear beam center.
The rear beam of the rapier loom can be adjusted up and down in order to adjust the length of the warp and the warp beam to the rear beam. Generally, when weaving different kinds of fabrics, the rear beam position is different.
