  • Patent number: 3968673
    Abstract: A flat strip of metal, preferably coiled upon itself, is fed into a draw press and subjected to pressure to produce a generally bowl-shaped workpiece having irregular outer edges within which is defined a pair of mirror-imaged toe cap parts. The toe cap parts occur in angularly opposed relation to one another and are surrounded by irregular edge portions. The toe cap parts are separated and gauged by a press operation in which parting is combined with a trimming operation in a unique manner. An improved tool construction for processing the workpiece includes mating die bodies which are progressively moved toward one another in contact with the workpiece. During a first movement inner sides of the toe cap parts are located in a centered position on one of the mating die parts. Further die movement operates to separate the toe cap parts. Completion of the die motion trims away irregular outer edges of each toe cap part and simultaneously die cut edges of the toe cap parts are conformed to a desired shape.
