  • Patent number: 4716800
    Abstract: For reducing the refitting time of high-speed presses as a consequence of the adaptation of the distances of stacking spindle and support members to the dimensions of the cutting tool to be interchanged and of the blank, the stacking spindle and the support members are arranged on interchanging rails adapted to be displaced out of the press table. Upon reaching the required height of the stack, the spindle tip adapted to be separated from the stacking spindle is held by a retaining device consisting of adjusting means and slide member so that the stack can be lowered to the discharge conveyor plane.

  • Patent number: 4024747
    Abstract: Apparatus for the conveyance of components punched out from a strip of material with the formation of a punched grid out of the working area of a press includes a feeding mechanism for conveying the strip of material into the working area of the press. At least one controllable ejector is arranged in an upper die for ejecting the punched-out components during the return stroke of the upper die onto the strip of material itself which is the conveyor. Lugs are punched into a remaining portion of the strip of material to be processed, behind the punched-out component, these lugs serving to retain the punched-out and dropped-off components on the strip of material.
