A system for performing necking operations on a can body includes a necker machine and a positioning system. The necker machine includes a frame; a processing arrangement having a plurality of components movable relative to the frame for performing the necking operations on the can body, and a drive motor having a shaft operatively coupled to the processing arrangement for moving the processing arrangement relative to the frame. The positioning system includes: an encoder associated with the drive motor for monitoring a rotational displacement of the shaft and a controller in communication with the encoder and the drive motor. The controller is structured and programmed to: receive an input from a user, the input being indicative of a desired movement of the processing arrangement relative to the frame, and to operate the drive motor using feedback from the encoder such that the desired movement of the processing arrangement is achieved.

A can seaming apparatus including a frame, a can handling assembly, a can driving assembly and a seaming assembly. The can seaming apparatus is configured to seal a lid to a can through a double seam can seal. The can is positioned and clamped between an upper and a lower chuck. The can driving assembly spins the can and the upper and lower chucks about an axis. The seaming assembly includes two rollers which can selectively be directed to engage the can to form the necessary crimping operations.

The present invention has an object of providing a container member supply device that has favorable workability at a time of disassembly and washing and suppresses the occurrence of abrasion powder in a container member. Provided is a container member supply device including: a container member separation unit that supplies a container member having a flange at a peripheral edge thereof to a pocket of a container member conveyance turret, one by one, wherein the container member separation unit has a plurality of cutout parts, and one of the plurality of cutout parts is constituted by a cutout groove that is integrally provided on an upper outer periphery of the container member conveyance turret and engages with a flange of a container member.

The present application is directed to a double seam modification tooling apparatus for double seam modification and the double seam modification process. More particularly, a tooling apparatus for double seam modification is provided which adds a third modification operation to the first and second double seam operations which form the finished double seam, as well as a process for modifying double seams to include patterns of integral slots, notches or threads, or the like, after the double seams have been previously completely formed by the double seam modification tooling apparatus. Child resistant lids can then be configured with mating tab notches or tab threads to allow for opening or closing the lid when the tabs are properly aligned with the notches and threads on the can rim modified double seams.

A drive assembly for a necker machine includes a plurality of motors, each motor including an output shaft, a plurality of drive wheel assemblies, each drive wheel assembly operatively coupled to an associated necker machine drive shaft, and a number of timing/drive belts operatively coupled to each drive wheel assembly.

Gripper for gripping a thin-walled aerosol can blank, having a base body which is made of a solid material and which has a bore passing through it along a central axis, an inner surface of the bore being provided with a circumferential radial groove extending outwards in the radial direction, and having a rubber-impregnated workpiece which is received in the radial groove, which has a radially inner gripping surface and a radially outer working surface, the working surface, together with mutually opposite axial surfaces of the radial groove and a radially outer circumferential surface of the radial groove, delimiting a fluid working space, wherein an integrally formed circumferential sealing profile is formed on the gripping ring adjacent to the working surface.

A can bodymaker includes a mounting assembly and a forming system. The forming system includes a plurality of forming assemblies, each forming assembly coupled to the mounting assembly, each forming assembly including a ram assembly with an elongated ram body, and a ram drive assembly operatively coupled to each forming assembly. The ram drive assembly is a direct ram drive assembly.

A quick-change vacuum starwheel assembly including at least one of a quick-change height adjustment assembly or a quick-change vacuum starwheel mounting assembly.

Methods and compositions, including nucleotide sequences, amino acid sequences, and host cells, for producing fatty alcohols are described.

A method of reducing a thickness and increasing a height of a cylindrical wall of a metal cup to form a can body comprises positioning a wall-ironing punch inside the cup, moving an annular wall-ironing die 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. Methods of altering a diameter of one or more regions of a can body are also disclosed.
