Abstract
A character-carrying disc made of plastic material is provided, on its front face, with four protrusions each provided with a circular-arc shaped blade, coaxial with a central mounting hole of the disc. Each blade is itself provided with a projection protruding radially inwardly of the central hole of the disc. These rolls are adapted to engage, by resilient deformation of the blades, in an annular groove provided in the end of a shaft of the machine on which the disc is mounted.
