Apparatus and method for applying force for example in pressure development of imaging sets.

摘要

A number of embodiments of apparatus for applying force across the width of a sheet are described. In one four roll embodiment particularly suitable for pressure developing of imaging sheets, the first and second rolls are aligned in parallel with each other, while a skewed roll backs up each of the first and second rolls. The backup rolls may alternatively be crowned. The imaging sheet is suitably directed into the nip to contact one roll at an angle of arc along the roll ahead of the nip.
