Abstract
A general winding and feeding apparatus includes a rotating shaft on the upper side of a standing wall of a base, and a motor is connected to the rotating shaft in the standing wall. A swing arm extends across a traveling material and is situated at a suitable position on the standing wall. Digital variable frequency methods may be used to drive the motor, which operates in conjunction with light-coupled sensors to detect the traveling speed of a material on the swing arm and sense a swing position of the swing arm. Feedback is generated in real-time to modify the speed of the motor, and the constant speed travel of the material can be achieved while being either wound or unwound.
