ABSTRACT:
A substrate to be laminated is passed from a feed and brush table through an adhesive spreader, which spreader applies a pattern of adhesive along the top and bottom surfaces of the substrate. An index table, having a plurality of supporting rollers, supports a bottom laminate to be adhered to the bottom of the substrate at a predetermined indexed location. The substrate is transported onto the indexing table to a predetermined indexed location while being supported along its longitudinal edges by cone-shaped rollers to maintain undisturbed the pattern of adhesive. At the indexed location, the substrate drops onto the underlying laminate in predetermined relationship thereto. A top laminate to be adhered to the top surface of the substrate is positionally indexed on the index table and lowered onto the substrate. The composite substrate and laminate unit is conveyed through a heat tunnel which applies heat and includes compressive rollers for applying progressive compression upon the composite unit to cure the adhesive. Trimmers at the exit of the heat tunnel trim the top and bottom laminates to the substrate width.
