Backpack webbing There will always be a variety of bad methods in the production process, which will leave a bad impression on customers. How can we avoid these problems? First of all, talk about the reasons for stitch skipping of webbing and the reasons for deviation of product size.
Reasons for stitch skipping of backpack webbing:
1. Needle stopper rod is not properly blocked;
2. The position of weft needle and knitting needle is not correct.
Protective measures:
1. Position the needle guard rod against the knitting needle;
2. Align the weft needle and the knitting machine so that the weft yarn can be hung completely.
Reasons for size deviation of backpack webbing products:
1. The raw materials are uneven in thickness, which makes the woven belt larger and smaller. The width of the woven belt should be measured frequently, and it should be adjusted immediately when it is found unqualified;
2. If the steel buckle is worn too large or too little, the size of the woven belt will be reduced. If the steel buckle is worn too large or too small, it will be worn again if it is not qualified. It cannot be forced to produce;
3. Looseness of the weft wheel during operation: tighten and fix the weft wheel;
4. When the weft yarn passes through the rod spring, there is yarn wool inside: often loosen the outside spring to make the yarn wool inside come out.
After learning these prevention methods, we will be able to better prevent needle skipping of backpack webbing in the future.
