The hight position of the beat-up of weft wire

The height position of the beat-up of weft wire refer to the height position from the bottom edge of reed where the cloth mouth contacting when the reed is beating up the weft. To weaving metal cloth, the commonly used height of the beat-up of weft wire is at 3-5mm away from the bottom edge of the reed. If the beat-up of weft wire is too lower, the warp joint is easy to be scratched by the reed; If the beat-up of weft wire is too higher, the rigidity of reed is sharply weakened when it is beating up the weft, It will cause reed deformation and form large holes between warp.
