Title: Compressed air actuated workpiece mechanism
Inventor: BOEHM KARL DIPL-ING
IPC: B21B21/04
Filed: 1969-11-06
Abstract: The method for the actuation of the workpiece feeding mechanism for reciprocating rolling in which the feeding-in motion is effected by means of compressed air and the braking by a fluid actuated brake, consists of compression of the air during the feed-in stroke to such a level that the air pressure acting on the side of the cylinder facing the rolls at the end of the braking path, during which the fluid brake acts, applies a counter pressure, which is approximately as large or only a little larger than the feed pressure applied onto the side of the cylinder facing away from the rolls. The beneficial result of this is that a lower pressure is applied onto the fluid brake.
