Abstract
A lamination trimming device is disclosed for trimming excess laminating film along edges of a laminated card or sheet product. The trimming is performed such that a border of sealed laminating film remains along edges of the product. The device includes lower and upper guide members between which the laminating film is retained. A cutting blade is positioned above an upper guide member for trimming off the excess film and a deflecting surface is provided on a lower guide member for guiding the device along edges of the laminated product and for deflecting the excess laminated film to be trimmed. Both straight and curved surfaces may be trimmed with the device disclosed herein.
