Claims17
A method of producing an arcuate brake shoe comprising the steps of taking a first generally straight strip of material which is to provide a web of the shoe and has a plurality of projections extending from one edge, taking a second generally straight strip which has a plurality of corresponding openings to receive the projections and which is to provide a platform of the shoe, securing the strips together with the projections inserted through the openings and forming both the strips longitudinally from their generally straight form to an arcuate form.
Apparatus for producing an arcuate brake shoe from a first generally straight strip of material which is to provide a web of the shoe and has a plurality of projections extending from one edge and a separate second generally straight strip which has a plurality of corresponding openings to receive the projections and which is to provide a platform of the shoe, said apparatus comprising a roller arrangement for occuring the strips together with the projections inserted through the openings and for forming both the strips longitudinally from their generally straight form to an arcuate form, the roller arrangement comprising a central roller and a number of satellite rollers circumferentially spaced around and co-acting with the central roller, the strips being passed between the central roller and the satellite rollers.
