Do you know what will be affected by the front and rear position of the rear beamof an electronic jacquard machine? Our company have summarized some contents for you. Let's have a look.

1. Increasing the height of the back beam is conducive to weft beating, fabric formation and fabric style;

2. Increase the height of the back beam to increase the difference between the upper and lower warp yarns. After the fabric is formed, it is conducive to the recovery of warp yarns and reduce reed marks or reed paths;

3. The upper warp tension is small and easy to relax, resulting in poor opening and increased weft stop;

4. When the height of the rear beam is low, it is conducive to the clarity of the weaving mouth, but the warp break increases and the cloth style is not good;

5. When the rear beam moves forward, it is conducive to clear opening, but the warp yarn is under excessive tension during opening, which is easy to break. Generally, the position of the rear beam should depend on the number of heald frame pages.
