Abstract

PURPOSE: To permit a mass production of a type wheel at a low cost by cutting, by utilizing a plurality of cutters, a type wheel rubber pipe rubber-formed by a shaping cavity and core to mount them on a basic board.
CONSTITUTION: A symbol and characters 6 and 7 are marked in the inside of a cavity block 5 to form a plastic cavity. Suhsequently, the plastic cavity is transformed into a ring configuration by the combination of four blocks with the joint faces closely contacted by each other, the outside thereof being clamped by a ring 8 . The cavity block 50 is fixed to form a shaping cavity. According to such a construction, a type rubber pipe 4 is rubber-formed, an electrocasting core 9 is inserted to the pipe for an electrocasting work for the cavity 10 to form an electric annealing plastic cavity 10. The plastic cavity obtained is cut down by a plurality of blades 12 to form a type wheel rubber 13, and a type wheel 1 is completed by mounting the rubber 13 on a plastic base.
