Abstract
A high-speed, cold laminating system includes a lamination unit for inline use connected with a paper feeder supplying at least 30 ppm. The lamination unit further includes a set of unheated motor-driven laminating pressure rollers along a laminating path, and a cutter between the rollers and an exit. A diverter gate passes the paper sheets to the laminating path or to the exit without passing along the laminating path. The system includes a controller to control the motor, the diverter gate, and functions of the lamination unit. The controller is programmed to control the motor to pause the pressure rollers with a leading sheet therein while a subsequent sheet moves toward the pressure rollers so a laminated spacing distance between a trailing edge of the leading sheet and a leading edge of the subsequent sheet to equal a prescribed spacing distance.
