ABSTRACT:
For converting a stepwise translation movement into a continuous translation movement and arrangement and a method is provided which have at least two fluid-operated cylinder-piston units with cylinders are rigidly mechanically connected with one another and pistons movable in the cylinders between end positions and having piston rods, removably arranging clamping mechanisms on the pistons of the cylinder-piston units, arranging end position sensors in the regions of the end positions of the piston of a respective one of the cylinder-piston units, arranging end position pre-signal sensors so that they are axially spaced relative to the end position sensors, connecting the sensors with electronic a control unit, and producing by the electronic control unit signals for supplying a working fluid to the cylinders of the cylinder-piston units in an alternating manner.
