Abstract (en)

[origin: ES8107397A1] Disclosed is a thermal pressure fixing device for a copier, comprising a pressure roll and a fixing roll for heating and pressing an image-receiving material carrying a toner image, whereby during the passage of the image-receiving material between the rolls the latter are in pressure contact with each other, whereas during a standstill of the copier or in the case of a copier malfunction, the pressure of the rolls is discontinued. There are provided a device for lifting the pressure roll toward the fixing roll and for separating the two rolls, and a clutch and brake mechanism interacting with this device. Resilient elements adapt the center distance between the pressure roll and the fixing roll to the changes occurring in diameter of these rolls, in such a way that the preset roll pressure between the rolls remains constant.
