A device for manufacturing a metal wheel (1) from a pre-form, with stretching rolls (3) engaging on the rim region of the pre-form, by means of which rolls a rim (1.1) is end-formed which, for forming a rim flange (1.7). Freely rotatable rolls (4) are arranged underneath the stretching rolls (3) and cooperate with them. A method for manufacturing a metal wheel (1) from a pre-form, the pre-form of the metal wheel (1) to be manufactured is placed on a clamping mandrel (2) and is caused to rotate, stretching rolls (3) engage an axially outer side of a rotation-symmetrical jacket of the pre-form with the exertion of radial pressure, and move along the jacket wall of the pre-form with compression and stretching of the jacket wall to form a rim (1.1) with a main movement component parallel with the axis of rotation (2.1) of the pre-form.

An installation for rolling a metal strip includes a rolling mill through which the strip is rolled as it passes continuously, rolling agents brought into contact with rolls of the rolling mill and with the strip, a strip drawing unit positioned at the outlet of the rolling mill, and a decontamination module with at least one degreaser positioned between the outlet of the rolling mill and the drawing unit so as to remove residual rolling agents from the strip at the outlet from the rolling mill. A strip accumulator is positioned at the outlet of at least part of the drawing unit, particularly so as to keep the speed of travel of the strip at the outlet of the accumulator below a maximum threshold. A paper-strip insertion module is positioned downstream of the outlet from the strip accumulator.

Provided is a bottomed tubular body processing device that performs necking on an opening end of a bottomed tubular body multiple times while conveying the bottomed tubular body along a conveyance path. The bottomed tubular body processing device includes: a multi-stage necking section in which a plurality of necking units are sequentially disposed along a conveyance path; and a circulating conveyor that refeeds the bottomed tubular body discharged from a downstream necking unit to an upstream necking unit. The circulating conveyor conveys the bottomed tubular body by retaining an opening end of the bottomed tubular body against a conveyance surface. A bottom turret of a processing turret constituting the necking unit supports a bottom portion of the bottomed tubular body and is movable in an axial direction by a position adjustment mechanism based on a height in a tube axial direction of the bottomed tubular body.
