ABSTRACT:
For inserts in boxes of bottled and canned goods, there is disclosed pad forming apparatus in which rotary dies are adapted to remove the edge portions of a roll or sheet of material, e.g., chipboard, as the roll is fed towards a rotary knife from feed rollers, the feeds being selected to determine the lengths of the pads for a given run, and the speeds of the rotary dies and knife being selected to effect material removal and cutting to insure that the pads of the selected length have rounded corners. The die parts are on rollers between which the material moves from the feed rollers, and are positioned so the edges of the material pass between them. Each die set has a punch on one roller and a slug shedder or ejector on an opposing roller, the shedder being spring biased and radially movable. The dies punch out cusp cutouts, and the knife cuts the material along lines through the midportions of the die cuts. As the dies separate, the shedders are released to eject the slugs of removed material. The rollers have longitudinal channels in which the die parts are located, and along which they can be selectively positioned for cutting cusps from the edges of sheets of different widths.
