Abstract

The printing platen construction substantially reduces the radiated sound when type elements strike it. The printing platen comprises a cylindrical metal core 10 which supports outer surface 11 of the resilient material. Received within core 10 is cylindrical damping member 12. The latter is made of a highly plasticized polyvinyl-chloride such as TYGON*. Member 12 is extruded or otherwise formed so it is easily inserted into the interior of the platen but yet exerts sufficient pressure on the internal surface of core 10 to attenuate the sound. * Trademark of U. S. Stoneware
