Abstract
An improved printing roller and method of making same, wherein a soft, loose, long nap fabric having a backing is bonded onto a roller shaft.

A method of making a printing roller comprising the steps of:
- providing a metal roller shaft;
- providing an unfelted fiber fabric having a backing and a loose, plush nap the fibers of which have one end bound to said backing and a free end projecting outwardly from said backing at least one inch with a fiber denier of about 6-15;
- cementing the fiber fabric backing to said roller shaft;
- impregnating the nap fibers and backing with a resilient binder to completely fill the pores in said nap and backing and forming a single layer roller medium extending outwardly from said roller shaft;
- and
- grinding the roller medium surface of the impregnated fabric to raise a nap on the outer surface thereof.
A printing roller having a metal roller shaft and a single layer roller medium extending outwardly from said roller shaft to a roller surface, said single layer roller medium comprising an unfelted fiber fabric having a backing and a loose, plush nap the fibers of which have one end bound to said backing and and a free end projecting outwardly from said backing at least one inch with a fiber denier of about 6-15, and which fiber nap and backing have been impregnated with a resilient binder, to form said single layer roller medium the single layer roller medium being ground to form a raised nap on said roller surface.
