Abstract: A can body manufacturing method has a barrel section of the can body held between first and second rotation bodies. The first body has at a first recess in its outer surface, and the second body has a second projection on its outer surface. The bodies are brought together so the barrel section is pressed radially inward by the second projection and fits into the first recess. When the holding of the barrel section by the rotation bodies is released, that portion of the barrel section corresponding to the first recess and the second projection is caused to restore elastically radially outward. As a result, the outer surface of that portion of the barrel corresponding to the projection and recess is caused to position more outside than the rest of the outer surface of the barrel section.

One method for forming the can forms the lidding material by using an outwardly extending curl (20) at one end of the metal can body as the draw die. Lidding material which is carried by the body maker punch is drawn around the curl of the can body draw die so as to form the lidding material into a cup shape.

Abstract: A can shaping process in which container preforms (F) are mounted on a table (16) which is rotated so a preform is moved from an initial loading station (P1) to a molding station (P4). A molding unit (20) includes a two-part mold (20a, 20b) split vertically in half, with inner surfaces (56) of the respective mold halves shaped to produce a desired container profile. Once the preform is in place, a pressurization unit (102) is lowered into place from above the mold onto an open, upper end of the preform. The mold is then closed and pressurized air is introduced into the preform. The air pressure forces the sidewall of the preform outwardly against the inner surface of the mold to conform the shape of the container to a desired profile. After the shaping operation is complete, the pressurized air is withdrawn from the container, the mold halves are moved apart from each other, opening the mold.

Abstract: Drawn and ironed aluminum can bodies are made from aluminum having a gauge thickness of 0.01075 inches or less, in which the bottom profile meets customer requirements for bottom performance in terms of buckle, drop and growth, without requiring the bottom profile to be reformed in a separate bottom profile reforming step.

Abstract: A new end wall or can bottom configuration for beverage cans and a method for its manufacture have been designed which provide an increased resistance to pressure and which allow an additional light-weighting of the can bottom.

Abstract: A method of making a non-cylindrical shaped metal can that is provided with a stylized, irregular shape includes steps of forming a substantially cylindrical sidewall portion (12) that has a plurality of ribs integrated therein. These ribs provide additional strength to the sidewall portion. The cylindrical sidewall portion may then be shaped into a non-cylindrical, stylized shape. The ribs (26) are preferably positioned at portions of the shaped sidewall portion (12) that are anticipated to need increased strength in order to withstand deformation under pressure. The sidewall (12) is then assembled to at least one can end member (30) to form a completed shaped metal can (28). The ribs may either be arranged longitudinally, circumferentially, or both may be provided to form a grid structure.

Abstract: A process for manufacturing a cylindrical metal can having, on its side walls, projected portions and recessed portions. The projected portions are formed by forcing the side walls radially outwardly, and the recessed portions are formed by urging unprojected portions radially inwardly while the projected portions are being forced radially outwardly.

Abstract: Two destacking tables and two can body forming stations are provided, the latter forming cylindrical can bodies from the metal sheets stacked on the destacking tables. These can bodies are subsequently conveyed along the feed axis to the welding station, which welds the longitudinal seam of the can bodies. The provision of two destacking tables and two can body forming stations enables these elements to operate at the cycle rate of the welding station. This permits welding to be effected with an increased cycle rate, with reliable feeding of the can bodies despite this.

Abstract: A film magazine forming apparatus forms a sheet having printing on a side thereof into an almost cylindrical shape. The film magazine formed into the almost cylindrical shape has separated lip portions for enabling a film to mvoe therethrough. The lip portions have a soft yarn mounted thereon. Transport apparatus transports the sheet to forming means including a core mold, an upper mold, and first and second side molds which form the sheet into an almost cylindrical shape with the printing on the side of the sheet forming an outer cylindrical surface of the almost cylindrical sheet. Transport apparatus transports the sheet with the printed side of the sheet being out of contact with the transport apparatus to prevent damage to the printing on the sheet. In addition, the core mold is used as a guide for transporting the almost cylindrical shape sheet to another operating position. A claw can be mounted on the core mold for transporting the thus formed almost cylindrical shape to another operational position.

Abstract: A carousel type head revolving about a vertical axis and skirted by a fixed reaction sector is equipped with work stations, each comprising a system of brackets to support the cylindrical tin can and a mandrel consisting in a shaft with an interchangeable outer barrel of diameter notably less than the internal diameter of the can, by which the revolving metal body is pinned against the fixed sector to bring about its deformation; the mandrel and brackets of each station rise and fall synchronously in mutual opposition between respective limit positions, each traversing through a vertical distance substantially equal to half the height of the production can.

Abstract: A substantially rectangular metal blank is formed about a mandrel (76) to provide a very open shell (28) having a pair of axially extending lips (20c,20t) separated by a distance sufficient to permit a prewound spool (10) or other product to be inserted radially, laterally into the shell prior to closing the shell about the spool or other product.

Abstract: An apparatus is described for positioning a can body in the form of a longitudinal seam welded cylinder which is provided with a tongue or the like projection at a predetermined point of its outer circuference, and which is to be further processed, for example shaped. The can body is received in a device in a spatially fixed manner and is rotated about its longitudinal axis. The rotational movement is stopped by a stop (48) or like sensor or obstacle in the path of the tongue, the position of the stop being so selected that the longitudinal seam of the body is then in a precisely defined position. The seam is thus detected in a simple manner by means of a tongue. It is thereby possible to ensure that when a circular cylindrical can body is, for example, further shaped into a parallelepiped body, the longitudinal seam is precisely in the middle of a narrow side of the parallelepiped body.

The apparatus includes a die cut edge movable into telescoping relationship around a redraw die to form the inverted cup and a profile punch movable into telescoping relationship within the redraw die to form the preliminary profile against a profile pad. The profile pad is selectively supported by a pair of fluidly actuated pistons whereby, upon activation of the second piston, the final profile may be formed.

Abstract: A system for trimming a can body wherein a can body is positioned within a cutting member so that the cutting member is at the location where the can body is to be trimmed. A resilient, deformable object is inserted into the can body and positioned therein so that at least a portion thereof is located radially opposite portions of the can body on each side of the cutting member. The resilient, deformable object is deformed so as to move a first part thereof against a portion of the can body to prevent longitudinal movement of the can body and then to move a second part thereof against the portion of the can body located between the cutting member and the open end of the can body in a radially outward direction so as to sever that portion from the can body.

Abstract: A system for forming a surface configuration, such as a neck and a flange, on a can body adjacent an open end thereof using a mandrel having an outer surface comprising generally cylindrical portions on each side of an annular recess which recess has a surface configuration corresponding to the neck and the flange to be formed. A resilient deformable object is located around the mandrel. A portion of a can body is placed between the mandrel and the resilient, deformable object which is then deformed so as to move a portion of the can body into conformation with the surface of the annular recess. At the same time, a force is applied to a portion of the portion of the can body being deformed to resist the movement thereof so that the portion of the can body in which the neck and flange is being formed is stretched and thinned as it is moved into conformation with the surface of the annular recess.

Abstract: The invention herein relates to a method of forming a one-piece can body having a reinforced pressure-resistant can end and/or stacking bead by first forming a generally cup-shaped blank defined by a generally cylindrical body, a radius portion and an end, exerting first forces against the cup-shaped blank in a first direction to form the end into a concavely outwardly opening end defined by a central end panel, a frusto-conical wall and an annular inwardly opening channel merging with the cylindrical body, and exerting second forces against the annular channel in a second direction opposite the first direction while gripping the central end panel to reform either or both the frusto-conical wall and a part of the annular channel to selectively form one or both of an inwardly projecting outwardly opening annular bead and an outwardly projecting inwardly opening annular bead defining respective reinforcing and stacking beads, and the first and second directions defining a single reciprocal opposing path of forc
