Abstract

Cards 24 are formed by intermittently die cutting both ends simultaneously from a web 10 of polyester material to provide cards of a width equal to that of the web. This "cookie-cutter" approach leaves a small scrap strip between cards, but assures that the cards will be of consistently accurate length with precisely positioned corner cuts or rounded corners being formed at the same time as the transverse end cut.

Card Cutting Apparatus

Cards 24 are formed by intermittently die cutting both ends simultaneously from a web 10 of polyester material to provide cards of a width equal to that of the web. This "cookie-cutter" approach leaves a small scrap strip between cards, but assures that the cards will be of consistently accurate length with precisely positioned corner cuts or rounded corners being formed at the same time as the transverse end cut.

During the punching stroke, the uncoated side of the web is attracted by vacuum to the punch 22 via ports 40 just before it enters the die 23a, 25b. Two U-shaped movable guides 20a, 20b that laterally support the web are spread apart to release the card as it is cut from the web; whereupon air under pressure is supplied to the ports 40 to divert the scrap strip 73 into a receptacle 75 and release the card 24 onto a conveyor 25 for stacking.
