Abstract
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. The fabric is impregnated with a resilient elastomeric binder to form a homogeneous roller medium from the shaft to the roller surface. The homogeneous roller medium is grinded to raise a soft, loose nap on the roller surface.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
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.
Claim 2
Independent Claim
121 words
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.
