Abstract

A patch lamination device includes a laminate feed roller, a laminating roller, and a laminate spreader. The laminate feed roller is configured to feed a patch laminate ribbon along a laminate path. The laminating roller is configured to laminate individual patch laminates of the ribbon to a surface of a card substrate. The laminate spreader is positioned between the laminate feed roller and the laminating roller. The laminate spreader is configured to reduce the formation of trough wrinkles in a patch laminate that is tensioned between the laminate feed roller and the laminating roller during lamination of the patch laminate to a card substrate using the laminating roller.
