The paste box belts has the advantages of softer, higher speed, more accurate and lower noise, which greatly improves the product qualification rate and labour productivity.

The transmission mechanism is controlled by a leveler with an infinitely variable speed motor. The motor uses a v-belt or a timing belt (toothed belt) to drive the main shaft gear, which at the same time is passed to the large disc gear, thus driving the needle barrel carrying the needles and carrying out the knitting. The main shaft is extended above the large circular machine and drives the yarn feeding disc to deliver the yarn in the required quantity. The drive mechanism is required to run smoothly and without noise.

Polyamide flat belt is made of high wear-resistant special synthetic rubber or leather as the friction layer and high-strength nylon sheet base as the skeleton layer, and its reasonable belt structure makes these products have excellent comprehensive transmission performance. Its long service life, transmission efficiency of more than 99%, transmission speed of more than 60 m / s, good curvature, dimensional stability, constant coefficient of friction.
