ABSTRACT:
An improved laminating machine having a supply of laminating material guided into the machine so a pair of webs respectively are fed through heating stations and then extend parallel to one another along a workpiece path in a direction towards a drive station. A supply of sheet material is delivered between the webs of laminating material. A pair of pressing rolls supported for rotation engage and bond together opposite sides of the heated laminating material and the sheet material to form a composite workpiece. Each heating station directs laminating material to the pressing rolls. Each heating station is formed in an arcuate configuration and includes a plurality of rollers and a plurality of heaters. Each heater is operatively connected with a respective roller. A pair of rotatable cooling rollers are supported along the path between the pressing rolls and the drive station. Each cooling roller has at least one coolant passage extending longitudinally therethrough. A fluid coolant flow is supplied through the passage in each cooling roller. The cooling rollers are located to engage opposite sides of a heated composite workpiece to cool the composite workpiece.
