Abstract

A measuring arrangement for a machine winding arrangement can determine a process variable related to the length of a wound-up or let-off material. A rotational angle signal is extracted from a rotatable winding carrier. In addition this angle signal can also contain information concerning the direction of rotation of the winding arrangement. The process variable is then calculated from this turning angle signal and calculation data, by means of a computer. The calculation data, transmitted from an input device, include at least values which are concerned with the diameter of the winding and thickness of the winding layer. The computer can contemporaneously be utilized to calculate the desired amount of rotation of a beam motor from: the process variable, a setting amount from the input device and a main shaft signal indicating rotation of the main shaft of the winding arrangement. The arrangement is particularly suited for the winding up or letting off of thread of a textile machine.
