An oscillating roller system for a beverage can decorator is driven back and forth by a cam follower. A cam body having a cam is mounted to a frame of the inker system. Three oscillating cam roller assemblies are positioned about the cam body. Rotation of the cam oscillates the cam followers for each one of the oscillating rollers. Bearings of the oscillating roller assemblies includes an inlet gallery and outlet gallery for a closed loop lubrication system. The rollers are water cooled.

An over-varnish unit and mandrel pre-spin system for a can decorator, especially for beverage can bodies, can have a mandrel pre-spin belt that is outside of the over-varnish unit housing. The position of the can infeed on the mandrel wheel and the print point is controlled.

A print registration system for a beverage can decorator includes an axial registration system and a circumferential registration system. Each registration system is independent and includes a slider that is translated by a motorized lead screw. Axial movement of the axial registration slider is transmitted to axial adjustment of the plate cylinder by a mechanical connection between the axial registration slider and the plate cylinder shaft. Translation of the circumferential registration slider is transmitted to a helical gear mounted to the plate cylinder shaft such that the plate cylinder shaft is rotated by the movement of the circumferential registration slider upon engagement of the helical driven gear with a stationary drive gear.

Print registration system for can decorator

A system for spraying a coating such as lacquer on the internal surface of a can body () comprising vacuum chuck gears () for each vacuum chuck (). The vacuum chucks hold the can body as it rotates about a main process turret () and to a spray station (). A ring gear rotates independently of main turret rotation and further gearing connects the ring gear to a vacuum chuck drive motor (). The spray system provides tight process control and allows flexibility of process revolutions or use of higher machine production speed.

System for spraying the inside of can bodies

An infeed system for a can body decorator in which undecorated can bodies are transported from an upstream supply in a conveyor (). In the conveyor (), the can bodies have a linear pitch as they are touching each other. One or more infeed turrets () separate each can body and change the pitch to the circular pitch of a separator turret and, ultimately to that of the mandrel wheel () in the decorator assembly.

In-feed system and method for supplying can bodies to a decorator

An infeed apparatus for the manufacture of containers such as can bodies, comprises a series of 3 or more infeed turrets (). The infeed turrets () take a can body as linear pitch and convert this pitch to a circular pitch. By use of the series of turrets, the can passes to a machine such as a container processing machine not only at a desired linear pitch but also at the specified processing speed. The exchange ratio between individual turrets () in the infeed turret series is variable and no greater than 2:1.

Container manufacture

An apparatus and method for transferring compressed air between machine elements uses a rotary manifold in which an orifice restrictor is provided between the air supply, between each piston and shoe. The orifice restrictors meter volumetric flow rate during loading and/or unloading cans from the apparatus, thereby optimised compressed air consumption.

An apparatus for handling articles () through a multi-stage process, the apparatus comprising at least one rotatable process turret () having a number of pockets (), wherein each pocket () is adapted to support an article (). The pockets () are arranged in groups and each group of pockets (A,B,C) has associated tooling (A,B,C), which carries out one stage of the process. The articles () are initially fed into one group of pockets (A) only. A re-phase means () is provided to transfer the article () from one group of pockets (A,B) to another (B,C).
