A cut-to-length steel coil processing line has an un-coiling reel, a temper mill, a stretcher leveler, a shearer, and a stacking apparatus arranged to sequentially process a continuous length of sheet metal. The line may be configured such that the continuous length of the sheet metal is directed from the uncoiling reel through the temper mill to the stacking apparatus without processing through the stretcher leveler when a determined thickness of the continuous length of sheet metal is at or below a selected measurement criteria. In the alternative, the line may be configured such that the continuous length of the sheet metal is directed from the uncoiling reel through the stretcher leveler to the stacking apparatus without processing through the temper mill when the determined thickness of the continuous length of sheet metal is greater than the selected measurement criteria.

A method for producing a shaped sheet metal component having wall thicknesses differing from each other is disclosed including providing a sheet metal material having a constant wall thickness, pre-shaping the sheet metal material into a preform by means of a hold-down press, producing at least one bulge in an inner region such that the material is stretched and has a reduced wall thickness, flattening and/or extending the produced preform, cutting the sheet metal material in order to form a blank before, during, or after the pre-shaping, and shaping the blank into the shaped sheet metal component.

Provided are a press forming method capable of improving material yield while avoiding the risk of dimensional error increase at product forming sections in blank material when carrying out press forming, and a plate material expansion device used in this method. An end side of plate material for press forming is restricted by blank holding rollers, and pressure is applied to a middle location in the part that is restricted by a pressure roller. In this state, the plate material is transported in a rotating direction of the rollers being driven to continuously bend and extend the section receiving pressure. This bent and extended section is flattened with a flattening roller to obtain blank material wherein an end part is expanded.

A method and apparatus are disclosed which are suitable for use in the manufacture of two-piece metal containers. In particular, a way of making cups from metal sheet is disclosed using a combination of stretching and drawing operations. The resulting cups have the advantage of having a base thickness that is thinner relative to the ingoing gauge of the metal sheet.
