ABSTRACT:
The separator machine disclosed includes a base and sheet feed means on the base. The sheet feed means includes a conveyor section having a plurality of parallel driven transverse feed shafts rotationally mounted on opposite ends of said shafts to advance the sheets along a guide to a nip roll and a plurality of cooperating idler rolls. The nip roll then drives the sheets to forwarding rolls located on either side of the machine. The forwarding rolls are controlled to have the same peripheral speed as the nip roll and to engage the sheets only along the opposite margins of the sheet parallel to the direction of travel of the sheets. The forwarding rolls move the sheets in register between a pair of opposing dies which move transversely of the sheet feed direction into mutual contact with the sheet at a progression of locations across the sheet to complete separation of the cards from the scrap. The relative transverse motion of the dies is accomplished by links of different lengths driving an upper die platen having a male die mounted thereon toward a lower female die by simultaneous rotation of an end of each of said links in an arc in one direction on one stroke and in the opposite direction in the next stroke. The male die includes a plurality of spaced projecting members for engaging portions of said sheet in the area of said tangs. The female die has a plurality of cutout portions in substantially the same arrangement and the same shape as the die cut cards of a series of sheets to be separated into cards and scrap such that the relative movement of the male and female dies into mutual contact with the sheet forces the cards progressively across the sheet from the scrap portion of the sheet and through their respective cutout portion in the female die to a sensing and automatically lowering elevator. The scrap is then driven from between the dies by the forwarding rolls engaging its opposite margins. A preliminary set of cooperating male and female dies can be provided between the conveyor section and the card and scrap separating dies to punch out internal cutouts in the cards, if desired.
