APPARATUS FOR STAMPING INFORMATION CARRIERS FROM A PLASTIC FOIL

摘要

In apparatus for stamping foils with a relief pattern, employing a resilient buffer pad to press the foil to be stamped against the matrix carrying the negative of the relief pattern, the buffer pad includes a plastic surface layer slidably disposed on a rubber elastic pad. This plastic layer provides the outer surface of the buffer pad which presses against the foil. In order to enable the plastic layer to be able to more easily slide over the rubber elastic pad, a slide layer is placed between the two layers. This slide layer can consist of a silicone paste. The buffer pad is outwardly bulged toward the foil when initially coming into contact with the foil and then as the buffer pad presses the foil against the matrix the buffer pad is flattened. To increase the ability of the buffer pad to be bulged in this manner, the buffer pad is placed upon a plastic pad which preferably consists of two plastic layers.
