Abstract: Open containers are fed along a shelf into position under a lid dispenser, which places a lid thereon. The containers with their lids are then clamped one at a time to a chuck head, and a seamer apparatus is rotated about the lid and container to seam them together. The seamer apparatus includes oppositely disposed pairs of seaming rollers carried by brackets that are slidably mounted on a rotating frame member, the brackets being operated by individual hydraulic cylinders which move the seamer rollers into and out of engagement with the lids and their containers. A key feature of the invention is that the pressure exerted by the hydraulically operated seaming rollers is fully adjustable, as is the speed of their movement about the periphery of the lid.

Abstract: The depressed dome portion of the cap is scored part way through the thickness of the material thereof and immediately adjacent the inner periphery of the overlying ring portion. The score forms a continuous line extending nearly completely around the dome portion but interrupted for a short distance to provide an unscored hinge portion. The depth of the score is sufficient to allow downward finger pressure on the dome portion to break the material thereof along the score line and permit the dome portion of the cap to be bent downwardly about the hinge portion and into the neck of the bottle to which the cap is attached.

Abstract: The tool pack is designed for mounting on a metal drawing machine or press, and includes a frame having a mounting slot for holding a cartridge that carrys a drawing die, the mounting slot having a right angle corner formed therein against which the cartridge is seated and removably secured by hydraulic clamping apparatus, whereby precise positioning of the cartridge is assured. The cartridge includes screw actuated fluid adjusters for precisely positioning the die in two directions, to secure accurate alignment. Mounted rearwardly of the cartridge is a stripper assembly including radially movable, pivoted jaws that are hydraulically extended and retracted to provide stripping action.
