Abstract
A print wheel assembly for a word processing machine utilizing a daisy wheel-type printer as a type-carrying disk in which the typefaces are mounted upon flexible members generally extending radially from a hub by which the wheel is mounted in the machine. According to the invention, a pigment carrier overlies the typefaces and can be of disk configuration and is so mounted on the wheel as to shift relative to the typefaces, whereby successive impacts are offset from one another for each typeface. The pigment carrier can be a bibulous or capillary fabric drawing ink from a reservoir dimensioned to supply sufficient ink to feed the transfer layer for the duration of the useful life of the wheel.
