A method and apparatus for producing a reducing neck and a peripheral flange on a free peripheral edge portion of a cylindrical container body is disclosed herein. The apparatus consists of a fixed frame having a waxing station, a necking station, and a flanging station defined thereon. The containers are fed from a source in a synchronized fashion along a path with the axis of the cylindrical bodies of the containers extending vertically and are moved past the waxing station where the cans are rotated relative to fixed brushes to apply lubricant to the outer surface of the peripheral free edge portion. The reduced neck on the container is produced by supporting the containers on a bottom member that is carried on the periphery of a turret and an upper member having an annular die with the bottom member being cammed towards and away from the die to produce the reducing neck of the container. The flanging of the container is accomplished with a flanging turret having a plurality of flanging assemblies on the periphery thereof each of which consists of an upper member that is rotated about a fixed axis in a sleeve on the turret and a lower member that is reciprocated towards and away from the upper member by cam means.

Method and apparatus for necking and flanging containers

A loading apparatus for supplying container bodies to a mandrel forming part of a can trimming machine is disclosed herein. The loading apparatus consists of a plunger that is guided on the machine frame for axial movement towards and away from the mandrel and moved by a shaft having an arm extending radially therefrom with a link connecting the arm and the plunger. The shaft is rotated between angular extreme positions by a continuously driven cam member to oscillate the arm between positions and reciprocate the plunger towards and away from the mandrel.
