  • Patent number: 5134931
    Abstract: A cylinder press converted to printing foil embossed images onto a printing stock. A supply roll of foil bearing ribbon is mounted forward on the reciprocating chase and the ribbon is extended over the chase through a pair of adjusting guide rollers to a stationary take-up mechanism. In the take-up mechanism, the ribbon is wrapped around a puller roller and onto a rewind roller. One of the guide rollers is stationary and the other reciprocates in a parallel path in at least half the speed of the reciprocating chase. The ribbon is wound in a serpentine configuration around the reciprocating guide roller forward to the stationary guide roller and back to the take-up mechanism to thereby retain a fixed pathway length regardless of the position of the chase. The ribbon is wrapped around the puller roller having a friction gripping surface for non-slip pulling of the ribbon.

  • Patent number: 4627343
    Abstract: Apparatus attached to the reciprocating chase of a cylinder press for carrying one or more supply spools of a web of foil-carrying material, together with an adjustable computerized controller and web-pulling rollers associated with the cylinder press and responsive to the controller, for holding a portion of the foil-carrying web suspended above the chase and moving the foil-carrying web a predetermined distance after each impression from the foil onto print stock. An articulated support rack extends from the chase to a structure supporting the web-pulling rollers, to maintain tension in the web as the chase moves. The controller is adjustable to pull a preselectable incremental length of the web a preselectable number of times and to pull a different preselectable length of the web automatically after each group of such selectable number of pulls each having that incremental length.
