ABSTRACT:
A device for successively transporting sheets in a platen press includes gripper bars with respective ends fixedly attached to two flexible of endless loop elements. Each loop element is engaged respectively with an intermittent drive wheel and at least one free wheel. A rectangular working chase and a movable platen arranged on both sides of the path of the grippers of the said bar. Nozzles are connected to a compressed air supply, for directing air jets towards the movable platen during a stopping phase of the gripper bars, in order to successively stop the sheets between the working chase and the movable platen. The nozzles are located below the transverse rear edge of the working chase.
