DEFINITION

Classification: 100/332

Roll temperature conditioning means is external of roll, but in direct temperature conditioning contact with roll:

(under subclass 327) Apparatus wherein the means for changing the temperature is placed immediately adjacent to the cylindrical pressure surface.

(1) Note. A roll press which is temperature conditioned within a heated or cooled container (e.g., an oven or cooler) is not considered direct temperature conditioning contact with the means for subjecting the material to compressive force roll.
