Abstract
Brake shoe ribs are formed in a continuous strip stock utilizing a method to decrease the amount of trim stock. The strip stock is selected to have a width approximately equal to the maximum dimension between the ends of a rib to reduce trim stock along the edges of the strip. Each rib is formed with a pair of notches in an outer periphery and the ends of an adjacent rib extend adjacent the notches to reduce the amount of trim stock between the ribs. A brake shoe table is attached to the outer periphery of a rib by continuous welding along both sides of the rib even across the spaces defined by the notches and a brake lining is attached to an outer surface of the table.
