PURPOSE:To prevent a heat and a press-contacting rolls from deforming owing to press contacting by delaying the releaseing of the press contacting between both rolls by a scheduled time to stop a device after the rolls are released from the press contacting. CONSTITUTION:The press-contacting roll is pressed against the heat roll through a cam mechanism by the rotation of a motor M2. This press-contacting operation is detected by a microswitch MS1, which turns on when the press contacting ends to supply a contact signal to a control part MC; and a control signal S3 is turned off to stop the rotation of the motor M2. The signal S3 is turned on, for exapmle, 20sec after fixing operation to drive the motor M2, and consequently when the press contacting is reset, a microswitch MS2 turns on to supply a contact signal to the control part MC; and the contact of a relay RL3 is broken by the control signal S3 to stop the motor M2. Consequently, the loss time in every original replacement is prevented and the deformation of both rolls due to the press contacting is prevented. |
