Method and apparatus for decurling laminated stock

摘要

A machine for laminating discrete sheets to a film F 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. The machine also includes dewrinkling mechanisms (44) for removing wrinkles from the film as it enters the laminating stations.
