Webbing manufacturer Backpack webbing During the production process, it is inevitable to encounter some accidents, which will lead to product quality problems. Such as curved belt. How to adjust in time? First of all, we need to understand how bending is caused. Generally, there are four causes.

Cause of belt bending: uneven threading of steel buckles; The pan head pulling yarn is uneven; The steel buckle is in the wrong position; The yarn receiving method is incorrect.

After knowing the causes of belt bending, how to take preventive measures next. The steel button threading must follow the normal threading method, one or two groups; Pull off some of the larger and looser side until it is as flat as the other side or 1-5 turns less; The distance between the steel buckle and the knitting needle is usually one empty distance; According to the needs of the webbing, it should be divided into upper and lower layers, or divided, left and right. Generally, it should be divided into upper and lower layers. If there are more than two methods or lines on a belt, it should be separated.

Causes of wave formation: uneven threading of steel buckle, too much yarn on both sides and too little in the middle; The steel buckle is too large, and the weft is too tight; The pan head pulling yarn is uneven, the two sides are pulled tightly, and the middle is pulled too loosely; The yarn receiving method is not correct, and the balance dropping pressure is not good.

Preventive measures: select standard steel buckles, and wear them in one or two groups; According to the needs of the width of the backpack webbing, choose steel buckles to wear; Change the yarn in the middle and on both sides, or pull down the loose yarn in the middle; It shall be connected according to the practice of webbing, and the balance weight shall be equal according to the number of strips.
