ABSTRACT:
There is disclosed herein an attachment for a laminating machine. The attachment permits one-sided lamination by adjustably imparting a reverse curling force to an initially curled laminate. The reverse curling force is imparted by bending and/or stretching the heated and laminated product before the film sets so as to offset the initial curl. This is done by drawing the laminated product over a bar edge and adjusting the draw with an adjustable roller.
