PROCEDIMENTO PER LA FABBRICAZIONE DEI MANICOTTI PARTICOLARMENTE DI BRONZINE PER CUSCINETTI

摘要

Bearing bushes are made in groups or pairs by progressive press tooling so that at each stroke of the press a group or pair of bushes is produced. The bushes may have at least one end which lies in a plane inclined to the longitudinal axis of the bush, and this is effected by providing the bush blank in the flat with a sinusoidal boundary line.
