1. Mechanical Tension Control:
- 60 degree fixed angle inspection screen, which has been verified thousand times to prove to be the most suitable angle for knitted fabric. It has the least influence for fabric tension.
2. Electrical Tension Control:
- The dancing roller will move up and down to control the fabric tension. It make sure the speed of fabric feeding, checking, rewinding are synchronized.
Suppose the speed of feeding and rewinding are not synchronous, the potentiometer installed on one side of dancing roller will send signal to the inverters on the feeding position and rewinding position, and inverters will adjust the speed to the same.
