The first fastener including an outer surface and a raised profile extending from the outer surface corresponding to the embossed indicia to be formed on the wall of the metal food can. The system includes a second fastener coupled to the second die portion. The second fastener includes a head portion including an inner surface and a recess formed in the head portion defined by the inner surface of the head portion. The system includes a pad of polymeric material positioned within the recess and coupled to the inner surface of the head portion.

A quick-change cartridge assembly for a conversion press includes a downstacker assembly having at least one can shell delivery apparatus for delivering can shells during use of a conversion press incorporating the quick-change cartridge assembly; one or more forming stations; a tab stake station; and a transfer belt. The transfer belt defines at least one active forming lane for conveying the can shells from the at least one can shell delivery apparatus to the one or more forming stations and the tab stake station during use of the conversion press incorporating the quick-change cartridge assembly.

A cam arrangement includes a cam plate and a cam follower. The cam plate having a body with a planar face and a number of cam channels defined in the body, each cam channel extending into the body from the planar face and defined, in-part, by a pair of opposing sidewalls. The cam follower includes a roller assembly having an upper roller member and a lower roller member. The upper roller member is engaged with a first sidewall of the pair of opposing sidewalls at a depth into the channel from the planar face, and the lower roller member is engaged with a second sidewall, opposite the first sidewall, of the pair of opposing sidewalls at the depth into the channel from the planar face.

A system for manufacturing a plurality of can bodies includes a number of forming machines for forming one or more portions of the can bodies. Each forming machine includes a number of removable components. The system further includes a maintenance device including a housing, a changeout arrangement coupled to the housing, and a controller positioned on or in the housing. The changeout arrangement is configured to selectively remove and replace a removeable component of one or more of the number of removeable components of one or more of the number of forming machines under the direction and control of the controller.

To provide a variant-can having a narrow part in the vicinity of a bottom part by performing a diameter-reduction process up to the vicinity of the bottom part on a trunk part of a can-body made of metal in a can-manufacturing device which processes the can-body being held by a pocket-shaped conveying part while conveying. It is provided with: a can-body pocket which holds a can-body by being in contact with a part of an outer circumference surface of a trunk part of the can-body; a base pad which presses a bottom part of the can-body along a can-axis direction; a die in which the trunk part of the can-body is press-inserted; and a clamping ring which protrudes from the base pad toward the die and is provided so as to move back and forth along the can-axis direction.

Provided are a method for manufacturing bottomed cans and an intermediate material for manufacturing bottomed cans capable of obtaining high quality bottomed cans with high accuracy in positioning and suppression of distortion and warpage while making a desired portion of a blank thinner, and reducing an amount of scrap to be discarded. A method for manufacturing multiple bottomed cans from a metal raw plate includes a coining step of coining at least part of an area to be blank that becomes a blank in the raw plate, after the coining step, a forming step of punching a blank from the raw plate and drawing the obtained blank into a bottomed can shape, and before the coining step, a buffering hole forming step of piercing a material flow buffering hole between the areas to be blank in the raw plate.

A bottomed metal cylinder includes, at a bottom portion, a ground contact portion, a rising portion extending upward from an inner side of the ground contact portion, and a dome-shaped bottom surface extending to the rising portion. An annular line originating from a local thin portion is observed at a peripheral edge portion of the dome-shaped bottom surface.

In a method of forming a beverage container, a can body is formed from a metal alloy. A can end is formed from a substantially compositionally identical metal alloy. The metal alloy is a heat treatable aluminum alloy. The heat treatable aluminum alloy is produced from up to 100% recycled aluminum material.

A can manufacturing method by deep drawing processing using a press machine, wherein a pre-step press machine, a post-step press machine, and a conveyor configured to convey a blank from the pre-step press machine to the post-step press machine are provided, the can manufacturing method including: first pressing for blank processing on a metal plate and coining processing to reduce a plate thickness of the blank by using the pre-step press machine; conveying the blank from the pre-step press machine to the post-step press machine; and second pressing for drawing processing and/or drawing and ironing processing to form a rectangular can by using the post-step press machine.

To provide a can manufacturing method performing air assist capable of smoothly pulling out a punch from a processed can by appropriately performing air assist. Provided is a can manufacturing method including drawing and/or drawing-and-ironing using a press machine, the method including stripping that includes removing a punch from a can after the drawing and/or the drawing-and-ironing. In the stripping, air is blown out from an air blowing port at a tip end of the punch to perform air assist of assisting extraction of the punch. In the air assist, a pressure of the air and/or a blowing timing of the air is adjusted for each shot to a pressure and/or a blowing timing according to a condition of the shot.
