The position of the back beam of the rapier loom has a certain relationship with the processing effect. Moreover, the processing requirements are different, and the position of the rear beam used is also different. Then, we need to understand how to determine the position of the rear beam of the rapier loom.

1. Woven fabric
If a rapier loom is used to weave the yarn fabric, the rear beam should be adjusted to the middle position as much as possible so that the weaving process can be optimized.
2. Weaving special fine yarn high density fabric
If a rapier loom is used to weave fine special yarn high-density fabrics, the back beam should be moved to the end to increase the warp tension. With the shed open, the wrap-around angle of the warp yarns to the rear beam is reduced. By reducing the possibility of warp breakage, this can effectively reduce friction and optimize the smooth progress of the weaving process.
3. Weaving roving
For those who use a rapier loom to weave thicker special yarn fabrics, they should know that in this case, the rear beam must be moved back to maintain uniform tension when increasing the wrap angle to optimize the fabric effect.
We need to adjust the position of the rear beam according to the type of fabric to be manufactured, and pay attention to keeping the position adjustment range of the rear beam within a reasonable range.
