Abstract
Abstract Transfer or cleaning roller for use in offset printing is flocked with fibers adhesively secured to the roller by a layer of elastic binder. The outer ends of the fibers project from the layer of binder but are coated therewith, with the possible exception of their tips, which may be free of binder in the case of transfer rollers.
