In the process of producing china Buttonhole Webbing, some unexpected situations will inevitably occur, resulting in unqualified product inspection. How to find out and adjust it in time? The following are several common problems in production and the corresponding prevention and adjustment methods:

China Buttonhole Webbing production problem 1. Curved belt

    Reasons for formation: 1. Uneven reed wear, 2. Uneven yarn drawing on the pan, 3. Wrong position of the reed, 4. Wrong splicing method
    Preventive measures: 1. The reed piercing method must be the regular piercing method, one or two sets of piercing. 2. Pull off the larger and looser side until it is as flat as the other side or 1-5 turns less. 3. The distance between the reed and the knitting needle is generally as long as one reed is empty. 4. According to the needs of the webbing, it is divided into upper and lower layers, or divided, left and right. Generally, it must be divided into upper and lower. If there are more than two methods or patterns on a belt, it must be connected separately.

China Buttonhole Webbing production problem two. Waves

    Reasons: 1. The reed wears uneven yarn, too much yarn is worn on both sides, and too little yarn is worn in the middle. 2. The reed is worn too large and the weft is pulled too tightly. 3. The yarn drawn on the pan is not flat, the two sides are tight, and the middle is too loose. 4. The yarn splicing method is wrong, and the balance falling pressure is not good.
    Preventive measures: 1. Choose standard steel reeds and wear them in groups 1 or 2. 2. According to the width of the webbing, choose a steel reed to wear. 3. Change the middle and both sides of the yarn, or pull down the looser middle. 4. Connect according to the method of webbing, and press the weight according to the number of strips.

China Buttonhole Webbing production problem 3. Poor needle edge

Reasons for formation: 1. The thickness of the weft yarn is uneven, 2. The needle up method is wrong, too long or too short, 3. The pan head goes abnormally, sometimes tight and sometimes loose. 4. The weft wheel is not round enough and deformed. 5. The needle holder is worn out.
Preventive measures: 1. Change another weft. 2. The knitting needles are long and short according to the thickness of the webbing. Generally speaking, the length of the knitting needle is just enough to retract the weft. 3. Fix both sides of the pan head firmly, and don't let the pan head rest against the iron frame on both sides. 4. Changed the weft wheel with a new one, 5. Change the fixed rod, or go to processing.
