Abstract: Type capable of being used for both printing and embossing consists of a heat-curable resin and is divided into three layers. The uppermost layer constituting a typeface portion employs a finely divided granular heat-curable resin and exhibits a high hardness and surface smoothness. The lowermost layer constituting an impact face portion employs a coarse granular heat-curable resin and exhibits low hardness and elasticity. An intermediate layer formed by mixing these two layers at the interface between them constitutes a joint portion exhibiting intermediate hardness.
Abstract: A printwheel for an impact printer includes a sheet metal core having a central disk portion and a plurality of radially extending arms. Sintered ceramic or metal character slugs are affixed to retaining regions at the ends of the respective character arms. A polymer film jackets the disk portion and adjacent regions of the character arms.
