A system for performing sequential operations on a can body, such as necking the open end of the can body, in which two or more machines, such as die necking machines are, are coupled by a transfer module. The transfer module comprises a multi-pocket wheel that receives can bodies from a multi-pocket discharge wheel of the first necking machine and discharges them to a multi-pocket input wheel of the second die necking machine. The drive motor of one of the necking machines is eliminated, while the drive motor on the other machine is enlarged. A gear on the transfer module couples the gear trains on the first and second necking machines into a common gear train. Thus, the transfer module gear train transfers power from the necking machine having the enlarged drive motor to the necking machine for which the drive motor was eliminated. This enables a single drive motor to entire drive train for both machines.

[ What is claimed:] [1.] A method for directly coupling first and second necking machines for successively reducing the diameter of the end of a can in a plurality of discrete operations, said first necking machine comprising (i) a plurality of first necking modules for partially reducing said diameter of said can end, (ii) a discharge wheel for discharging said partially necked can, (iii) a first motor and (iv) a first gear train driven by said first motor, said first gear train comprising a first gear driving said discharge wheel, said second necking machine comprising (i) an input feed wheel for receiving said partially necked can, (ii) a plurality of second necking modules for further reducing said diameter of said can end, (iii) a second motor, and (iv) a second gear train driven by said second motor, said second gear train comprising a second gear driving said input feed wheel, said coupling method comprising the steps of:a) installing a transfer wheel between said discharge wheel of said first necking machine and said input feed wheel of said second necking machine so that said transfer wheel receives said partially necked cans from said discharge wheel and delivers said cans to said input feed wheel;b) installing a third gear so as to mesh with said first and second gears, said third gear driving said transfer wheel, whereby one of said first and second gear trains drives the other of said gear trains; andc) eliminating at least one of said motors so that only one motor drives said first and second gear trains, whereby said one motor drives one of said first and second gear trains which drives said third gear which drives the other of said gear trains.
