ABSTRACT:
To regulate the wire tension, a wire tension regulator is disposed on a winding device for electrical coils. A return roller and a contact roller can be mounted on the regulator for prebraking of the winding wire. The winding wire is subsequently wrapped 360.degree. around a wheel brake. The wheel brake is driven in the forward and backward directions of the wire by a d.c. motor. A strain gauge is disposed between the brake wheel and the winding device. The d.c. motor generates a signal indicating a rotor position to a motor control unit which transmits the position as an amplified signal to a control device and, as a derived set value wire tension signal which also reaches the control device. In addition, a set value wire tension signal of a machine control unit or a set value wire tension signal of a wire tension preset is provided to the control device. The set value of the wire tension is compared with a signal representing the instantaneous wire tension. The control device emits a set value signal to the motor control unit which passes it along, amplified as an energy supply, to the d.c. motor to convert the tension of the wire from its present value to the set value.
