ABSTRACT:
There is provided an attachment for use on a somewhat standard sheet laminating machine of the type including two vertically spaced upper and lower heating elements defining therebetween a pass along which sheet material moves in a direction from the front to the back of the elements. Each heating element has a front facing, curvilinear heated donor surface extending transversely of the workpiece pass and curved in a direction generally parallel to the pass. This type of sheet laminating machine also includes two vertically spaced pressure rolls behind the heating elements and extending transversely of the pass with one of the rolls on each vertical side of the pass. The attachment includes first and second heat conducting elements formed from a metal havng high thermal conductivity, with each of the heat conducting elements having generally flat platen plates and integral heat receptor portions. The heat conducting elements are mounted together at the platen plates and the heat receptor portions have receptor surfaces generally matching the donor surfaces of the previously mentioned heating elements. In this manner, the attachment may be mounted directly onto the heating elements with the donor surfaces contacting the receptor surfaces so that heat energy is conducted to the receptor surfaces and from there to the platen plates between which the workpiece to be laminated is fed for subsequent lamination by the pressure rolls.
