PROBLEM TO BE SOLVED: To prevent a pressed finished material W from being wound round a heat roll 13 by improving a calendar type roll finishing machine without a heating head, and to prevent the occurrence of creases due to floating Wf of the finished material. SOLUTION: Pressure air is jetted as indicated by an arrow A from a main jet orifice 3a provided in an air pipe 3. Thus, the finished material W is separated from the heat roll 13, and floating Wf thereof is restrained. When pressure air is jetted as indicated by an arrow B from an auxiliary jet orifice 3b, prevention of floating is further completely implemented. COPYRIGHT: (C)2005,JPO&NCIPI
