Abstract

1316695 Making springs; angular bending; bending cutters NORTH AMERICAN ROCKWELL CORP 23 April 1971 [1 June 1970] 10975/71 Headings B3A B3E and B3W [Also in Division F2] A method of making an integral eye structure at an end of a spring leaf 11 comprises longitudinally slitting the leaf adjacent an end to provide edge regions 19, 21 and an intermediate region 18 and oppositely displacing the regions 19, 21 and the region 18 to form opposed loops defining the spring eye. The eye is formed by dies 33, 37, the former of which is provided with a projection 35 and the latter with a pair of projections 39. The projection 35 enters between the projections 39, Fig. 10 (not shown), and the side edges of faces 36, 42 co-operate to shear the leaf. Alternatively, the strip may have longitudinal slits formed prior to shaping the eye. The eye may be formed at one or at both ends of the spring leaf.
