A method of forming a carrier ring on a metal article having an open end and a sidewall extending therefrom. The method includes contacting an inner surface of the sidewall with an inner roller to form a protrusion and contacting an outer surface of the sidewall with an outer roller to form a first groove positioned below the protrusion. The protrusion forms a gap therein. The method further includes contacting a portion of the outer sidewall with at least one second outer roller to form a second groove below the protrusion. The method further includes contacting a portion of the outer sidewall with at least one third outer roller to flatten the protrusion, such that the gap is substantially reduced or eliminated. The flattened protrusion forms the carrier ring.

Molds for forming formed containers with reduced or eliminated parting lines, and systems and methods of forming the formed containers, using electromagnetic radiation are disclosed. In some aspects, the forming mold includes a multi-segment mold disposed about an electromagnetic coil. The multi-segment mold having a plurality of circumferential segments, a bottom mold section and an annular ring. Each of the circumferential segments including an inner surface wherein the plurality of inner surfaces defines a desired shape of the formed containers. The bottom mold section being adapted to hold and move the pre-form articles about an electromagnetic coil and into and out of the forming mold. The annular ring being adapted to hold, seal and optionally shape a top section of the pre-form articles so as to reduce or eliminate parting lines on the surface of the formed containers.

Systems and methods of forming articles using electromagnetic radiation are disclosed. In some aspects, the system includes a plurality of forming modules movably mounted relative to an infeed mechanism. The infeed mechanism is configured to supply pre-form articles to the plurality of forming modules, and each of the plurality of forming modules includes a multi-segment mold disposed about an electromagnetic coil. The electromagnetic coil is configured to impart an electromagnetic force on the pre-form articles when supplied with electrical energy that urges the pre-form articles into contact with the multi-segment mold to produce the formed containers.

The multi-segment mold having a plurality of segments, each segment including a mold insert having an inner surface. The plurality of inner surfaces defining a desired shape of the formed containers. Each mold insert being comprised of a material that comprises at least one of small pores, grooves, pockets and crevices. The material comprising the at least one of small pores, grooves, pockets and crevices being configured to allow air to pass through the multi-segment mold or to allow the air to be less compressed.

The present invention relates generally to a container that may be sealed and reclosed with a threaded closure. More specifically, the present invention relates to methods of manufacturing a metallic container having an opening with inwardly facing threads that are formed after a threaded closure is inserted at least partially into the opening. The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads.

A horizontal can necking machine assembly includes a plural of main turrets and a plural of transfer starwheels. Each main turret includes a main turret shaft, a main gear mounted on the main turret shaft, a pusher assembly, and a die capable of necking a can body upon actuation of the turret shaft. Each transfer starwheel includes a transfer shaft and a transfer gear mounted on the transfer shaft. The main gears are engaged with the transfer gears such that lines through the main gear center and the centers of opposing transfer gears form an included angle of less than 170 degrees, thereby increasing the angular range available for necking the can body. The main turrets and transfer starwheels may operate to neck and move at least 2800 cans per minute, and each pusher assembly may have a stroke length relative to the die that is at least 1.5 inches.

A turret-head assembly including a turret head-assembly support member defining a turret-head axis and a base plate having an aperture through the center thereof, the turret head-assembly support member extending therethrough. The base plate is rigidly coupled to the turret head-assembly support member. The turret-head assembly further comprises a front housing and a pivot plate positioned between the base plate and the front housing. A first side of the pivot plate is coupled with a first side of the front housing. A second side of the pivot plate is coupled with a first side of the base plate. The pivot plate is axially movable along the turret-head axis. The turret-head assembly further comprises a plurality of rollers coupled to the pivot plate. The plurality of rollers is configured to move radially with respect to the turret-head axis. The radial movement corresponds with the axial movement of the pivot plate.

Coupling of conveyor belt modules A module (2) for a modular conveyor chain, comprising a link portion (3) made of sheet metal that includes a substantially elongate conveying body (4), the conveying body having a central hinge loop (5A) on one longitudinal side thereof and a pair of offset hinge loops (5B) on an opposite longitudinal side thereof that are interspaced to receive the central hinge loop of a link portion of a consecutive module therebetween. The central hinge loop and/or or the offset hinge loops are distanced with their free end(s) from a bottom face of the conveying body to form a through pass aperture (16) through which a hinge pin (12) held in the hinge receiving space(s) of the hinge loops of other module may pass transversely to its axis into or out of its hinge receiving space.
