摘要:
A regulation device for the rotary drive of a warp beam of a weaving machine for producing as uniform as possible a tension force on an unwinding material or group of warp threads conducted to a weaving device and then to a fabric take-up device. A tachometer is associated with a power regulator arranged ahead of the motor of the rotary drive as a momentary value transducer and comprises a generator for generating a signal corresponding to the tension force or tensile stress in the material or warp threads as well as a further generator for generating a signal corresponding to the take-up speed of the fabric being woven from the unwinding material or threads. These two signals are connected to a multiplier stage whose output signal is conducted to the power regulator of the rotary drive as a reference value. This feedback regulation of the rotary drive of the warp beam in dependence of the momentary tension force or in the unwinding material or threads and of the momentary take-up speed of the woven fabric by, multiplying the corresponding potential values of the signals for generating the corresponding reference value signals for the rotary drive, renders it possible to achieve a high constancy of the tension force on the unwinding material or threads even under non-uniform conditions in the further processing of the fabric.
