摘要： A can bodymaker comprising: a ram; a drive mechanism; a yoke coupling the ram to the drive mechanism in order to drive the ram with a linear, reciprocating motion; a yoke slide fixed relative to the can bodymaker, the yoke being confined by the yoke slide to move in a linear direction; and an alignment mechanism for aligning a yokecoupled end of the ram with respect to the yoke within a plane perpendicular to said linear direction.

摘要： A method of reducing a thickness and increasing a height of a cylindrical wall 13 of a metal cup 11 to form a can body comprises positioning a wall-ironing punch 40 inside the cup, moving an annular wall-ironing die 24 axially over the closed end of the cup towards the open end of the cup, but not beyond the open end of the cup, in order to iron the cylindrical wall from the closed end up to a position axially spaced from the open end and moving the wall-ironing die back in an opposite direction to remove the can body from the die. A step of moving the wall ironing die back in the opposite direction may be carried out with the punch positioned inside the can body in order to burnish a portion of the cylindrical wall. The base 12 of the cup 11 may be pushed against the punch 40 by the outer base-clamping tool 25 and the outer base-forming tool 26. The metal cup may include a flange 14 surrounding the open end and the method may include applying a force to the flange to remove the can body from the punch. Compressed air may be introduced into the can body 1 through channel 47 in the punch 40 to assist pushing the can body 1. A method of reducing a diameter of one or more regions of a can body is also disclosed by: pushing an annular tool having a number of portions of different diameter axially over the can body; and pushing a punch inside the can body, the punch having a number of portions of different diameter, wherein at least one portion has a diameter corresponding to a desired reduced can body diameter, to form the can body wall against the punch.

摘要： A can body spraying machine comprises a can body spinning device, a spray gun for spraying a coating onto an interior of a can body mounted on the can body spinning device and a controller configured to cause the spray gun to switch when the can body spinning device is in a correct spraying position. A sensor coupled to the can body spinning device determines when the can body spinning device has undergone a predefined rotation following commencement of spraying and, in response to such determination, causes the spray gun to be switched off.

摘要： A method of attaching a metal end (7) to a metal container body (6) in order to close an opening in the body, wherein the body (6) has a curled lip at least partially surrounding the opening and the end (7) has an upstanding lip extending at least partially around a periphery thereof. The method comprises locating the end (7) within the body (6) at or near said opening, bringing a curling tool (8) into contact with said upstanding lip of the end (7) and applying a force to that lip, via the curling tool (8), in order to curl the upstanding lip around the curled lip of the body (6) to form interlocking curls.
