Method and apparatus for decurling laminated stock

摘要

A laminating machine includes a heated laminating roller (22) and a back-up roller (26) that are driven at different speeds to produce a controlled reduction in the peripheral surface speed of the back-up roller in relation to the peripheral surface speed of the laminating roller through a brake (90) to control curling in the laminated product. The laminating machine also includes pull rollers (100 and 102) that are driven by the back-up roller and are angularly adjustable to control the path of movement of the product along with dewrinkling mechanisms (44) for removing wrinkles from the film as it enters the laminating stations.
