ABSTRACT:
An arrangement for generating and causing a pressing member to exert a pressing force includes an electric drive motor and a parallelogram transmission connected to the pressing member for transmitting pressing force thereto. The parallelogram transmission is coupled to and driven by the electric drive motor through a displacing member having the form of a screw spindle. An adjustable-setting switching device terminates operation of the motor when the output torque of the motor reaches a value corresponding to the setting of the switching device. The parallelogram transmission has a transmission ratio which in an undesirable manner is a function of the extent of displacement of the parallelogram transmission. Compensation of the functional dependence of the transmission ratio upon the extent of displacement of the parallelogram transmission is effected by automatically adjusting the displacement of the switching device in dependence upon the extent of the displacement of the parallelogram transmission.
