ABSTRACT:
Disclosed herein is an apparatus for moving material such as metal sheets or strip in production machines. The apparatus includes two spaced-apart, double-acting jacks disposed in parallel relation to the direction of movement for the strip. Each jack comprises two piston rods extending out of opposite ends of the cylinders from a common piston. The piston rods are secured at their free ends to standing columns arranged at the four corners of a rectangular base. A cross member rigidly interconnects the cylinders of the jacks and is provided with two transport grippers having jaws, one of which is moved by a jack to grip the strip at opposite sides thereof. The grippers are disposed in a plane containing the strip and longitudinal axes of the piston rods so that applied forces to the strip coincide with the driving plane of the cylinders.
