ABSTRACT:
The work clamps of a punch press are mounted in laterally spaced relation on a carriage which may be shifted to cause the clamps to re-position a workpiece relative to the punch. To enable automatic adjustment of the lateral position of the clamps on the carriage, each clamp is adapted to be selectively and automatically locked to or released from the carriage. When released from the carriage, each clamp is adapted to be automatically held in a stationary position so that the carriage may be shifted relative to the clamp to permit re-positioning of the clamp along the carriage.
