Claims
- 1. The method of making rivets and other headed articles comprisng the steps of:
- successively loading a blank in a direction from one end toward the other end of a plurality of blank holding dies supported for concurrent lateral indexing movement in relation to laterally spaced working stations and for independent axial movement at each of said stations;
- simulataneously shaping said blanks in a pluraity of said dies after concurrent lateral indexing movement thereof to said working stations to form a head against the other end of each die, each blank thereby being shaped progressively upon indexing movement to successive ones of said working stations;
- axially positioning each blank and each die at each of said stations independently of others of said blanks and said dies at others of said stations as necessary for the performance of each of said shaping steps concurrently; and
- returning all of said dies to a common axial position after each of said shaping steps and prior to indexing movement of said dies.
- 2. The method recited in claim 1 in which said blank loading step is performed by advancing linear stock material into each of said body dies at one of said stations and shearing said stock material in increments of length equal to the length of each blank using the one end of each of said dies as one of a shearing die pair.
