ABSTRACT:
An automatic laminator such as may be used for depositing layers of photoresist material on both sides of a base panel in which movement of the base panel during the laminating operation is continuous and overheating of the photoresist film layers is prevented. On each side of the inlet to a nip between a pair of heated rolls there is provided a main vacuum bail for holding the leading end of a web of photoresist film, and a secondary vacuum bail for pulling the leading end of the web are around arcuate end of the main vacuum bail. A first air cylinder which moves the main vacuum bail in a direction perpendicular to the plane of the base panel is itself movable in the same direction by a second air cylinder which also carries a third air cylinder, the latter moving the secondary vacuum bail in a direction parallel to the plane of the base panel. A nozzle plate is disposed opposed to the inlet of the heated rolls to cause the leading end of the web to be deposited smoothly onto the base panel.
