Abstract
Abstract The present invention discloses a machine for continuously punching holes in a substrate which is to be used in a skin packaging operation. The machine includes a frame which has a punching roll, which is rotatively mounted by the frame and the punching roll includes a cylindrical shell and a cylindrical center roll. The cylindrical shell is provided with a plurality of openings and fitted in these openings are a plurality of punching pins and these pins are backed up on one end by the cylindrical center roll which prevents them from inward movement. The outer surface of the cylindrical shell is swedged tightly around each of the pins where it exits its respective opening and this prevents outward movement of the pins during normal operation of the machine. The outward end of each pin is pointed to perform a punching function. A rubber backup roll is mounted preferably below and parallel to the punching roll. Means are provided for raising and lowering the punching roll relative to the rubber backup roll so that the outward end of the pins may be positioned relative to the rubber backup roll and preferably are at least in contact with the rubber backup roll. Means are provided for rotatively driving the punching roll and the rubber backup roll. Pieces of substrate are fed into the entrance end of the machine and are removed from the exit end of the machine by means of a plurality of belts which are mounted generally horizontal and parallel with each other. The belts are driven by means of first-drive axles which in turn rotatively carry sheaves which in turn carry the belts. The same construction is provided at the exit end to remove the substrate after they have had the holes punched in them by the aforementioned pins. Ejection rollers are mounted at the exit end of the machine and are adapted to engage the upper surface of the increments of substrate to aid in removing the substrate from between the punching roll and the backup roll. Weights are provided for varying the pressure of the ejection rollers on the increments of substrate. This prevents the punching roll from its normal tendency of pulling the pieces of substrate which are trying to exit the machine around the punching roll.
