DISPOSITIVO DI BLOCCAGGIO IN PARTICOLARE PER BLOCCARE UN PACCO DI FOGLI NEL CAMBIO DELLA PILA IN DISPOSITIVI IMPILATORI PER FOGLI DI CARTA O DI CARTONE

摘要

A clamping device for a sheet clamping machine comprises a pair of horizontal bars with tongues engaging on opposite sides of a sheet stack and drawn together to generate the clamping action by a piston-and-cylinder unit mounted on the back of the lower bar and having a piston connected to a cable which passes through the lower bar and then is guided vertically upwardly to the upper bar where that cable is attached. The cable thus applies a clamp closing force perpendicular to the bars.
