After holding a metal pipe 10 using a clamping die 5, a primary formed portion 11a corresponding to the preforming surface portion 5c is formed on the metal pipe 10 by pressing an end portion of the metal pipe 10 with a pressing die 6 in a direction of a cylinder center line C1. A final formed portion 11b is formed on the metal pipe 10 by moving an outer forming die 7 to press an outer circumferential surface of the metal pipe 10 with the outer forming die 7 after aligning a rib portion 7c with the primary formed portion 11a, while moving an inner forming die 8 to press an inner circumferential surface of the metal pipe 10 with the inner forming die 8 after aligning a recessed groove portion 8c with the primary formed portion 11a.

A shell, a container employing the shell, and tooling and associated methods for forming the shell are provided. The shell includes a center panel, a circumferential chuck wall, an annular countersink between the center panel and the circumferential chuck wall, and a curl extending radially outwardly from the chuck wall. The material of at least one predetermined portion of the shell is selectively stretched relative to at least one other portion of the shell, thereby providing a corresponding thinned portion. The tooling includes a pressure concentrating forming surface.

An apparatus and method of making and applying threaded twist-off neck finishes for metal containers is provided. More specifically, the present invention relations to apparatus and methods used to form metallic bottles with threaded necks adapted to receive selectively removable threaded closures. The threaded neck may be formed by interconnecting a threaded outsert to a metallic bottle. Alternatively, the threaded neck may be formed as an integral portion of the neck of the bottle.

A conversion press wherein a crankshaft drives the motion of the tooling assemblies within a number of lanes is provided. The crankshaft is structured to move the tooling assemblies associated with less than the total number of lanes. That is, for example, a four lane conversion press could include two crankshafts each actuating the tooling assemblies of two lanes. In an exemplary embodiment, each lane has a single associated crankshaft.

A manufacturing method for a screw-threaded bottle-can including the steps of: forming a shoulder part, a pipe part, a tapered part and an aperture-end part above a trunk part; and forming a screw-thread part by an inner mold and an outer mold in which the pipe part is sandwiched therebetween. An outer diameter of the pipe part is formed to an intermediate diameter between a ridge diameter and a bottom diameter of the screw-thread part. The screw-thread part is formed from the tapered part to the pipe part so as to form a screw-starting part at an intermediate position of the tapered part. A height of a first step of a right-hand screw-type protrusion of the inner mold is formed to be lower than a height of a second and subsequent steps in an angle range of 90° circumferentially continuing from the screw-starting part.

A conversion system wherein a crankshaft drives the motion of the tooling assemblies within a number of lanes is provided. The crankshaft is structured to move the tooling assemblies associated with less than the total number of lanes. That is, for example, a four lane conversion press could include two crankshafts each actuating the tooling assemblies of two lanes. In an exemplary embodiment, each lane has a single associated crankshaft. The conversion system includes a multiple press drive assembly with a clutch/brake assembly and a flywheel assembly. The clutch/brake assembly is structured to suspend operation of the press units while the flywheel assembly stores energy in a flywheel. When operation of the press units is restarted, energy from the flywheel aids the motor in bringing the press units to an operating speed.

The present invention relates to an apparatus for processing a sealing lip of a metallic can, and a metallic can processed by the apparatus. The present invention provides an apparatus for processing a sealing lip of a metallic can comprising: a pressurization block which is lifted and lowered by a lifting means to elastically provide pressure downward; an interlocking means which moves downward step by step by the pressure of the pressurization block and has a coupling relation in which the means stops at stages in the level difference structure of a base so as to be held; and a lip processing member which presses the sealing lip to the inside and outside of a bottle neck of the metallic can while interlocking due to the movement of the interlocking means, and provides a metallic can wherein a notch groove is processed at a beading part by the apparatus for processing a sealing lip of a metallic can.

In case of manufacturing tear-off lids (28) out of lid rings (20′) with a tear-off foil (25) sealed on them and with a tear-off tab (29) the tear-off tab is fixed in a folded back position onto the tear-off foil of the lid by an adhesive patch (30). For this, the adhesive patch is applied onto the foil section in such a way that individual adhesive patches are separated out of an adhesive tape with a carrier tape and an adhesive material arranged thereon by a separating means. Such an adhesive patch is arranged on the foil section of each lid in a position where the folded back tear-off tab comes to lie. By this, a fixing of the tear-off tab can be reached in an economical and secure manner.
