Abstract:

A device for pressure fixing powder images utilizing a pair of rollers in pressure contact and in skewed relationship, each of the rollers formed with a solid shaft or core encased in a tubular metal casing and including an elastomeric collar that fits into a recess formed by circumferentially cutting out portions at the ends of the shaft and the casing and supports the shaft at its ends inside the casing providing an annular air space between the shaft and the inside casing wall. The shaft ends are received in conventional bearings and under high compressive loads the shaft deflection is much greater than the deflection in the casing because of this elastomeric collar permitting much smaller skewing angles, particularly for rolls that exceed 10 inches in length.
