Abstract

A method of manufacturing packers for use in coupling the valves of an internal combustion engine to a camshaft thereof, characterized in that it comprises the following steps: a) cutting a plate (1a) from metal foil. b) a first stuffing operation on the plate to make a relatively flared surface (1b); c) a second drawing operation to shape the surface (1b) into a relatively deep bush (1c); d) forming, in a plurality of stages, the end transverse wall (4) which is pressed inward along the side tubular gland wall to form a folded shoulder (3) so that the transverse wall defines, with the cylindrical wall, a cavity on each face thereof; e) pressing a quantity of teeth (8) projecting inwardly into said cylindrical wall (2), to provide a plurality of supports for the transverse wall (4); and f) cut two diametrically opposite incisions (9) in the folded edge (3).
