Abstract

1324259 Rolling mills MANNESMANN AG 18 Aug 1970 [25 Aug 1969] 39651/70 Heading B3M [Also in Division F2] A device for returning a workpiece after it has passed through the rolls of a pilger mill (not shown) comprises a pneumatic pistoncylinder actuator whose strole is liquid damped. As the workpiece passes through the rolls it moves a ram 1 and piston 2 from left to right in a cylinder 3. When the rolls release the workpiece, return movement is imparted to the piston 2 by compressed air in the chamber 6. As the piston moves to the left, liquid in front of the piston flows to an unpressurized reservoir 9 at first through a slot 8 in the cylinder wall and then through apertures 11 whose lateral width increases towards the end of the cylinder.
