An electrocoating machine has a frame supporting a series of tanks containing solutions for electrocoating work pieces such as can ends. A wheel is mounted for rotation on the frame and has a plurality of work piece holders spaced about its periphery. Each work piece holder has a pair of spaced, flexible fingers, each having a free end which is cantilevered from the wheel. As the wheel rotates, cams displace the free ends of the fingers at a point shortly before they enter the electrocoating tank. A work piece transfer apparatus places a work piece adjacent the displaced fingers at a pickup point. The cams then release the fingers so they engage the work piece in spring-loaded gripping relation. The wheel carries work pieces from the pickup point, down into the electrocoating solution and then to a rinse conveyor.

Transport apparatus for electrocoating machines

A method and apparatus are disclosed and can be used to fabricate a complete container end closure including an inwardly tipped cover hook located along the peripheral extremity. The apparatus and its use in performing the method are unique in that one tool does all the forming to produce the complete end closure. More particularly, the cover hook is preformed by a first tool operation and then finally formed by a subsequent step wherein the preformed end is reformed to a final configuration in a step which is completely independent of the first tool.
