Q：What happens to weft insertion in GA747 rapier looms?
A：You can consider straight track, which is dangerous, but it will have immediate effect
Weft insertion and mouth opening are very important. There are technical problems, too. For example, when the palm is flat, the upper warp is used to press the weft
Rail jacking is also common
The yarn can allow the weft yarn to go behind the track, so that the track can not reach the weft yarn
As far as possible into the sword time late, flat brown do early drag layout and heald frame height according to the site conditions to do high will lead to let track from the top instead of weft weft hooking more serious
