Printing disc with damping means

摘要

In a type disc composed of: a hub; a plurality of spokes extending radially from the hub and spaced apart about the circumference of the hub to form slits between the spokes, each spoke carrying, at its end remote from the hub, a type face arranged to be driven against a record carrier by a printing hammer; and a damping arrangement associated with the spokes for damping vibrations, the arrangement is constituted by a mass of a selected material partially filling each slit and connecting together the spokes adjoining each slit, the material being selected to have a composition which is more elastic than the material of each spoke.
