Abstract

Shells for commutators are made by performing a number of forming operations on stock metal strip before the strip is cut into lengths and rolled into a cylinder. A roller (14) forms parallel transverse grooves (18) and ribs (19) in one side of the strip. Punches (26) cut slots (27) in alignment with the grooves (18) to form fingers along one edge of the strip. Knives (32) skive under the ribs (19) to form anchors (41). Then the strip is cropped into lengths by a punch (43), bent into a cylinder by a two-stage press and forced through a tapered sizing die (61). All operations are performed in automatic sequence on a multi-stage slide press machine.
