A method of and an apparatus for controlling the drive of a machine element of a spinning or twisting machine for exact positioning of the machine element at setpoint positions within a certain tolerance limit using motors which are not speed variable and are controlled by an on-off switch. The overshooting of the setpoint position can be detected and the measure of overshoot used as correction values for subsequent approaches to the setpoint position or to allow reverse approach to the setpoint with detection of overshoot beyond the tolerance and then a new approach with the iteration to a deviation less than the tolerance limit or a maximum number of cycles.

Method of and apparatus for controlling the movement of machine element

A control system for a production machine especially a spinning machine has a multiplicity of working stations each of which has at least one sensor to determine an operating parameter and at least one effector for carrying out a control operation. The modules responsive to the sensor signals and the modules for producing commands to the effector are connected together in chains and the one end of each chain is connected to a central unit providing the management circuitry and is capable of initialization of the module chain. Data transmission is effected from module to module along the chain.

Control system for a production machine, especially a ring-spinning

A rotary position sensor is connected to the belt of an apparatus for receiving the full bobbins and delivering the empty bobbin cores to both sides of a spinning or twisting machine. The microprocessor control unit has a memory which stores the restarting positions of the belt and, based upon the count in this control unit of the pulses from the sensor, the motor driving the belt is brought to a standstill.
