ABSTRACT:
A laminating machine for laminating outer sheets one on each side of an inner sheet, in which all three sheets are moved along in alignment, one spaced above the other, with their edges enclosed by adjustable side covers. The side covers together with the top and bottom sheets form a chamber. Contact adhesive is sprayed on the sheets at the entrance to the chamber. Heater bars span the chamber near the entrance to dry the adhesive. A suction box at the other end of the chamber draws air through the entrance, over the adhesive and heater bars, and then exhausts the solvent laden air. Beyond the suction box, pinch rollers compress the three sheets together to laminate them.
