Abstract
A device for feeding web material to a printer that is adapted to accept web from an external roll, adequately align the web with the printer and properly tension the web as it passes through the printer. The infeed device includes a pair of parallel guide rods spaced sufficiently apart to allow passage of the web there between. A pair of edge guides, attached to the parallel guide rods define the web path there through. A spring-loaded pressure pad acts in combination with a smooth metal shoe to tension the web. Further tension is applied to the web as it passes a curved smooth metal surface, just prior to entering the printer. The infeed device allows a wide variety of web materials and web thicknesses to be tensioned and fed into the printer.
