ABSTRACT:

The improved fixing assembly having a mechanical wide nip formed by a pair of nip forming belts with at least one of the belts being formed by multiple overlapping loops of cold rolled stainless steel. The ends of the stainless steel are secured to the loop adjacent to each end of the stainless steel. The stainless steel flexible formed belt may be coated and heated. Each belt is driven by a pair of internal friction drive rollers with the drive rollers being driven by a toothed belt engaging the drive rollers. The width of the nip is adjusted by changing the center distance between the friction drive rollers of the flexible belts.
