ABSTRACT:
A device for controlling the speed of sheet materials which are fed to a deep-drawing station in a packaging machine. The sheets are advanced by the control device in a step-by-step manner toward the deep-drawing station. The speed of the motor is controlled in a step-by-step manner by a rotating cam member engaging either a part of the conveyor for the sheet material to measure a predefined length of movement by the conveyor for the material. The motor is started slowly so that the sheet material is accelerated slowly to a maximum speed and is thereafter decreased slowly in speed until it is stopped by reason of the measuring reaching the predefined limit.
