Abstract
A machine, particularly for stamping or nibbling, comprises a reciprocating tool drive having a plurality of tools connected to the drive for selective reciprocation thereof. The drive includes means for stopping at least one of the tools for exchange purposes and a tool-change member is mounted for movement alongside the tool drive and includes a member movable transversely to the reciprocation direction for engaging and removing a tool which is stopped or disconnected from the drive in order to effect an exchange with another tool without stopping the drives of these other tools. The machine also includes means for engaging and moving a workpiece transverse to the reciprocating direction. One or more tools may be exchanged by the use of a movable conveyor magazine which carries a plurality of tool sets along its length which are selectively positionable into alignment with a fluid-pressure operated piston and cylinder combination having means for engaging a tool which is aligned therewith and positioning it in a location for engagement by the reciprocating drive for the tools of the machine.
