A method and apparatus for the installation of interchangeable core lock caps that replace the prior art individual cap installation techniques with one that, with in a single highly repeatable operation, punches the caps for a plurality of pin chambers from a strip of appropriate metal and frictionally fits them into the plurality of pin chambers. The method and apparatus of the present invention reduce the possibility of misalignment of the caps with the pin chambers to virtually zero and eliminate entirely the need to handle the small caps. These advantages are achieved by: 1) placing a lock core having pin chambers in a fixture below a slanted die having apertures registered with the pin chambers; 2) placing a strip of metal in a fixed position over the die; and 3) through a mechanical plunger linked to a plurality of punches, driving the plurality of punches sequentially through the metal strip to form punched metal caps. The punched metal caps are then driven into frictional engagement with the registered pin chambers of the lock core through continued action of the plunger and punches.

Capping system and method

A portable hand-held device for code cutting notches in a key blank by a punching mechanism permits quick and easy modification to accommodate key blanks of different configurations and keys requiring different notch depth, notch spacing and notch angle. A key-gripping vise slidably held by a carriage moves transversely to the punch to achieve proper notch spacing. The carriage is controllably moved to different heights above the punch by detents in a circular drum, whereby the depth of the notch is determined. The punch rod and matching anvil may be replaced to achieve a different notch angle.
