ABSTRACT:
Apparatus including a pair of opposed conveyor belts for feeding a plurality of superimposed continuous sheets of refrigerated, thermoplastic material. The active runs of the conveyor belts are guided over platens movable toward and away from each other in a direction normal to the path of movement of the sheet material to generate the necessary tractive forces required to advance the sheet material between the conveyor belts. The platens distribute the tractive forces uniformly over a large sheet contacting area of the belts to prevent cracking and rupturing of the sheet material. Means are provided for compressing the spaced-apart clamping assemblies of a frame assembly to which the sheets are attached for further processing.
