Abstract
PURPOSE: To improve durability and printing quality by a method wherein the front part provided with types of a type part is formed by a metal plate press work.
CONSTITUTION: Each front parts 5a, 5b alone of an outside type part 4a and an inside type part 4b is manufactured by metal plate press forming and this front part 5a or 5b is combined monolithically by a connecting part 6 in the form of a ring. In order to set easily them to the mold, each front part 5a, 5b is combined monolithically by the connecting part 6 in the form of a ring and engagement with the mold is strengthened by catch parts 8 in the time of insert molding. In insert molding, each front part 5a, 5b in the form of a ring is set at positions determined by each letter on the mold and the mold is closed. The front part and the connecting part 6 are cut by blocks 9, 10 located between the cavities and simultaneously the cavities 11 are formed. Material is fed to the cavities 11 under pressure to be molded, then the molds are opened to obtain a printing wheel wherein the front parts 5a, 5b of thin metal plate are inserted in type parts 4a, 4b of each finger 3.
