Abstract

PURPOSE: To prevent scratches of a press roller in a simple and secure manner, by controlling a necessary relationship between a cam and a switch associated with a press controller for a heating roller and a press roller at start through a microcomputer.
CONSTITUTION: Power supply starts motor 8 through a microcomputer even when microswitch 42 is off, irrespective of the relation between cam 40 and switch 42 depending on the rotation position of rotary shaft 10 determined by motor 8 of a press mechanism corresponding to a press condition between heating roller 4 and press roller 2. When shaft 10 rotates, rollers 2, 4 become maximally apart and come into a perfect noncontact condition, cam 40 and switch 42 come into a given relation, and this is detected, motor 8 stops, and a consequent process control regulates switching on the heater of roller 4, permitting prevention of scratches of roller 2 caused by roller 4 heated irrespective of the contact condition between rollers 2, 4 after the preceding use.
