ABSTRACT:
The speed of the friction drive drum is electronically controlled as a function of the thread speed. The apparatus allows winding of a precision wound package or a random wound package. The apparatus employs an electronic control unit which calculates a desired value signal for the speed of the drive drum as a function of the thread speed from a mathematical formula and compares this value to the actual value in order to obtain a correction signal for the drive of the drive drum. A similar calculation is also made for controlling the speed of the traversing thread guide shaft.
