ABSTRACT:
In the heating or cooling of conveyor or power transmission belts or similar articles during manufacture, successive regions of the article are presented to a zone wherein they are subjected to pressure accompanied by simultaneous heat transfer, the displacement of the article between applications of pressure being short compared to the length of said zone. Only preferred apparatus comprises a continuously rotatable heated drum over which said articles are passed, a tensioning roller having its axis parallel to that of the heated drum and movable towards and away from the drum, at least one curved, heated platen or equivalent member movable towards and away from the drum for exerting simultaneous heat and pressure on said articles, and means mounting said platen member for limited arcuate movement circumferentially of said drum and whereby said member is enabled when urged against said drum to move circumferentially and in synchronism with the same.
