Abstract
Multiple strips of foil are continuously and precisely laminated to a substrate by a process which comprises the following steps: (1) coating rolls of foil on one side with an adhesive, (2) slitting the adhesive-coated foil to the desired width(s), (3) mounting the slit rolls onto an unwind shaft, (4) pulling each foil strip through a first guiding spool fixed on a rigid shaft, (5) pulling each foil strip through a second spool mounted on a shaft, (6) placing the foil strips onto the substrate, and (7) handling the resulting laminate product by any known and convenient method.
