US Patent:

41499255, Apr 17, 1979

Filed:

Aug 8, 1977

Appl. No.:

5/822822

Inventors:

Leonard A. Mintz - Norwood MA

International Classification:

B32B 3120

US Classification:

156361

Abstract:

A machine comprising a stack of cards, a stripping feeder for stripping the bottom card from the stack and moving a series of such cards with an intermittent motion to a series of feed rollers which convert such intermittent motion into a constant velocity and for spacing the cards one from another. A tape coated with magnetic material is laid on the surface of each card by a guiding device after the card has passed through the feed rollers and the combination is fed between a heated roller and a reaction roller which are driven synchronously with the cards. The heated roller is pressed against the cards at a constant pressure exerted by an air cylinder to seal a portion of the magnetic coating to each card. The tape, carrying the sealed cards, is driven, pulling the cards along a track, allowing for cooling time until they are stripped off the tape by a stripping station which deposits the completed cards upon a belt moving at right angles to the tape-card combination in such a way that one card overlaps another, allowing the operator to view for inspection that part of the card to which the magnetic material has been applied.
