Publication number: 20080164241Abstract: To fix a valve piece encompassing a connecting shell and a valve to a can jacket, an embodiment of a method includes a welding step in which the connecting shell of the valve piece is fastened to the can jacket as a top closing element along with the valve by laser welding. According to an embodiment, a shoulder-shaped constricted cross section is embodied on the can jacket towards the top face thereof while the border area of the closing element which rests against the shoulder is tightly pressed thereagainst and is sealingly joined to a laser seam, the top face of the can jacket lying inside the can. The method dispenses with the need to configure or fix a valve seat while eliminating the technically complex crimping step, thus also dispensing with the need for an installation used for crimping connecting shells in the filling station. The method makes it possible to produce also aerosol cans whose diameter is smaller than the diameter of a standard valve seat.Type: ApplicationFiled: June 17, 2005Publication date: July 10, 2008Applicant: CREBOCAN AGInventor: Werner Boltshauser

Patent number: 6533518Abstract: Ends for cans are made in a single press, eliminating the need for separate shell and conversion presses, balancers, track work, and other equipment, as compared to existing can end manufacturing systems, while reducing floor space and capital investment requirements for installation of a new can end line. A sheet of end material or stock is introduced into the press and fed to a series of work stations. The sheet is maintained in a substantially continuous and void free state as the work stations perform forming operations on the sheet of material to form one or more ends therein. After the forming operation is complete, the end is ejected from the press. The maintenance of the sheet of material in a substantially continuous and void free state permits precise movement of the sheet through the press, and registration of the sheet relative to the tooling in the press.Type: GrantFiled: August 31, 1999Date of Patent: March 18, 2003Assignee: Rexam Beverage Can CompanyInventors: Timothy L.

Patent number: 5186593Abstract: A method of feeding work products such as can ends between different processes having different throughput requirements uses various feeding apparatus. In the first process, the work products are continuously mechanically treated at the same time by a group of first machines and then continuously discharged to a second process. This second process receives the work products fed from the plural discharging parts of the first machines. The apparatus in the second process has fewer receiving inlets than discharge parts of the first machines. In the second process, the work products are further mechanically treated. The method feeds the work products discharged from the plural discharging parts in the first process along respective feeding paths and then quickly feeds a predetermined number of work products to form a group of work products. This group is held in an arranged state in respective stay parts connected to the feeding paths.Type: GrantFiled: August 6, 1991Date of Patent: February 16, 1993Assignee: Hokkai Can Co., Ltd.Inventors: Shinichi Tsukada, Yoshiharu Iizuka, Hideyuki Tamura, Osamu Sakashita

Patent number: 4419168Abstract: Apparatus is provided for handling gasket-forming material. This material is usually supplied in tubular cartridge form and is dispensed to a screen with a porous pattern which shapes the material to the desired gasket-configuration. The material is spread on the screen and forced through to the other side where the gasket pattern is applied to an adjacent transfer surface of a transfer pad. This pad with the pattern on the transfer surface is moved to a mateable surface of a workpiece located on a support spaced from the screen. The gasket-forming material is then transferred to the mateable surface. The gasket-forming material is dispensed from the cartridge with the aid of a cartridge holder having an opening at one end to receive a spout of the cartridge and having a plunger at the other end with a plunger rod extending outwardly therefrom. A fluid-operated cylinder is aligned with the plunger rod and has a piston connected with the rod.Type: GrantFiled: October 13, 1981Date of Patent: December 6, 1983Inventor: William A. Paul
