Abstract:

Pressure rolls useful in printing, embossing, coating, calendering, conveying, and fixing images to substrates. The pressure rolls comprise a cylindrical core provided with an array of axial slots, a heating element disposed in the slots, and a shell around the core. The pressure rolls may be employed in apparatus for fixing a toner material image pattern on a substrate such as a paper sheet. The pressure contact between the sheet and the pressure rolls is established by a hydrostatic assembly which may be pre-set.
