First, the cloth roll fades to one side
The cloth roll fades to one side, which is due to the fact that the cloth surface is tight, one side is loose and the arc is formed. Don't put the winding frame diagonally, it is not a cure. Of course, there are also factors that reduce the tension of the winding.
Second, the cylinder is on the offset side of the upper traction roller
If the cloth is always offset on the side of the upper traction roller, when the expander is installed, the top of the expansion rod is offset from this side and is not centered. The treatment method is to adjust the expansion rod to the middle position.
Third, the cloth is swinging left and right on the upper traction
The reason is that the bottom end of the expansion rod is not fixed with the expansion rod seat ring, and the upper end swings to drive the cloth cloth to swing left and right on the upper traction. The treatment method is to fix the expansion rod and its seat firmly.
Fourth, the cloth surface is uneven
There are many reasons for the unevenness of the cloth surface. One of the reasons is that the expansion rod does not tighten with the woven cloth. If the four expansion rods and the woven cloth are always in contact, the tube cloth is stretched around, the latitude of several shuttles is slightly different in tension, and the weft yarns are out of the sleeve, and the expansion of the expansion rod can also be adjusted to balance the sleeve; When the warp is tight and the tension is relatively tight, the tight warp is pulled out a little from the ring gauge to adjust the warp balance. The four expansion rods always touch the cloth surface, and the cloth surface is inflated, and the cloth surface is flat.
