ABSTRACT:
Machined steel blocks 1 and 2 have ridges 20 facing valleys in the opposite block. Polypropylene tape 3 to be heat-treated has sliding contact transversely over each ridge on each block. The blocks are heated by heaters 4. The gap between the blocks is adjustable to suit the material being processed. The gap is large enough so that the tape passing between the blocks is not constrained to deflect from coplanarity by more than its own thickness.
