Abstract

There is concern that the technology for roll fusing will not handle large paper widths, i.e., 17", without wrinkle. In this context, the problem of wrinkle appears to derive from a number of sources. One is the increase in the size of the paper from the relatively dry center to the relatively damp edges. Another is that the fuser rolls may not have perfectly parallel cylindrical surfaces so that the fuser roll nip may not move in the process direction without sideways components.

WIDE ROLL FUSING (Cont'd)

Referring to the drawing in Figure 1, it is proposed that two roll fusing stations 4, 5 be provided in series to in effect divide the fusing into overlapping zones. The fuser roll pair 6, 7 of the first fusing station 4 are centered and are approximately 11K" wide. The assumption here is that 11%" paper can be handled well and further that a 17" wide sheet will have a more uniformly humid band than does an 1 I" wide cut sheet.

The second fusing station 5 has split fusing roll pairs 87 9; 10, 11, which divide the remaining area between them with some overlap. Each would be about 3" wide and would fuse the relatively damp edges of the paper in narrow strips with the expectation that the interaction of the nip and paper will,...
