1. A method of making bushes having the plane of at least one axial end thereof inclined to the longitudinal axis of the bush, comprising:
- (a) scoring strip material to provide a succession of groups of bush blanks so that adjacent edges of adjacent blanks in each group lie along common score lines, such common score lines having an undulating wave form and a length of one wave length, and so that each group of blanks is provided on a portion of the strip material of uniform length;
(b) successively forming the groups of the blanks to a circular cross-section tubular element consisting of a plurality of bushes interconnected along said common score lines between them, all the blanks of each group being so formed simultaneously and the longitudinal axis of the element being parallel to the direction of said uniform length;
(c) successively separating the tubular elements, or the groups of blanks before forming into such elements, from the remainder of the strip material; and
(d) separating the bushes of each group from each other along said common score lines.

Abstract
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.
