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.
