Feeder belt extension reasons:
1. The rubber used for the feeder belt is different. If it is reclaimed rubber, the quality of the belt itself is poor, and it will extend during use;
2. The skeleton layer of the belt is mostly made of canvas, which is low in cost and easy to stretch, so it will be easy to extend.
Features of non-extending feeder belts:
1. The seamless skirt is firm and does not fall off - using high-frequency vulcanization technology, the skirt is seamless and strong;
2. The use efficiency is doubled - polyester fiber strong cloth is used as the skeleton layer, which is resistant to compression, does not deform or stretch;
3. Stable operation--infrared shaping process is adopted, and the joints are flat and firm;
