  • Method for the production and assembly of lock parts
    Patent number: 4389764
    Abstract: A method for punching disc-like lock parts from a metal band or the like and for combining them to form lock mechanism units determining different lock combinations or the like. The punching of the parts to their final form takes place in a series of punching actions carried out by different punching units. Punching of parts having different details is carried out by having the pattern of the series changed for each punching stroke. In a final phase, the punched lock parts are separated from the band and collected in an order determined by a pre-selected combination code.
