Abstract

PURPOSE: To improve the pressure fixing strength of the object to be fixed by providing a difference of about 0.5 to 12% to the surface speeds of the upper roll and lower roll which hold the object to be fixed therebetween.
CONSTITUTION: Pressure rolls 3, 4 are connected by means of gears 5, 6 of the same number of teeth and revolve at the equal number of revolutions but the outside diameters of the pressure rolls 3 and 4 are differed by about 5% and therefore the surface speeds of the rolls differ. The backup roll 7 of the pressure roll 3 is twisted about 1° in order to even the pressure at the passing of the body to be fixed. A spring 8 for applying the pressure in the normal direction of the pressure rolls at their contact faces is provided to the object to be fixed which passes between the pressure roll 3 and pressure roll 4. A slight difference in the surface speeds of the rolls enables the higher pressure fixing strength than that by conventional ones even under the same linear pressure to be obtained.
