ABSTRACT:
There is shown an actuating device comprising a piston and cylinder unit having a piston with a metal forming configuration on the side thereof from which a piston rod projects and a recess is provided in the rod adjacent the configuration. The arrangement is such that upon impact by that side of the piston from which the rod projects on an end wall of the cylinder the material of the end wall is deformed into the recess to prevent rebound of the piston. The device is also illustrated in combination with an explosive operated initiating element. The rebound prevention principle is also shown utilized in a technique for joining two workpieces in which a fastener has a metal forming configuration adapted to deform the material of one of the workpieces into which the fastener is driven, the deformed material of the workpiece being moved into a recess adjacent the deforming configuration.
