Air Saving Fast Can Handling Process and Device

A can making machine for forming a can from a work piece, such can making machine having at least one punch, such punch carrying such work piece through a constricted tooling to increase an interior size of such work piece, such work piece having a tendency to become engaged to such punch for a period of time due to vacuum formation in such interior of such work piece as such punch increases such interior's size, the can making machine comprising:

• a source of air pneumatically connected to a pressure regulator;
• the pressure regulator pneumatically connected to an receiver tank;
• the receiver tank pneumatically connected to a high speed valve;
• the high speed valve controlled by a signal generated by a programmable logic controller, the high speed valve operable to supply high pressure air;
• the valve pneumatically connected to a pneumatic check valve;
• the pneumatic check valve pneumatically connected to such punch;
• the high speed valve not supplying the high pressure air continuously to the pneumatic check valve and such punch;
• the high speed valve supplying a plurality of pulses of the high pressure air to the pneumatic check valve and to such punch and such interior of such work piece while such work piece is engaged to such punch for such period of time;
• whereby such work piece is disengaged from such punch without the high pressure air being continuously supplied.
