Abstract: A two-high rolling stand (1) for bar and/or wire rolling mill. The rolling stand (1) is characterized in that a roll package, which substantially comprises a pair of rolls (13) with their axial directions in parallel and necessary bearing devices (14) with bearings and bearing housings for supporting said rolls (13), is located between two side plates (16) or the like, which are in parallel with each other, and of which each plate (16) is arranged with its main extension plane (17) substantially in parallel with a plane through the centre lines of the rolls (13). The roll pair further is characterized in that the side plates (16) on opposed sides of said roll package are arranged to take up roll forces via two end members (18), and that the roll package is arranged so as directly and/or indirectly to rest against the end members (18).A further characterizing feature is that said end members (18) are arranged so as to permit adjustment of the roll distance, so-called roll gap adjustment.

Abstract: A method and an apparatus, FIG. 1, for manufacturing sections (9,10,11), preferably for manufacturing beam preforms.The method is characterized in that a blank (7) with rectangular or square cross-section is forged between a pair of web tools (1,2), in that the web tools (1,2) are moved to and from each other for forming a web portion (9) on said blank (7), and is forged against flange tools (3,4), in that the tools are moved to and from the web tools (1,2) in a direction perpendicular to the direction of movement of the web tools. The blank portion located between the web tools (1,2) and respective flange tool (3,4) is upset to form flange portions (10,11) between the flange tool (3,4) and respective sides (1',2',1",2") of the web tools (1,2).The method further is characterized in that the blank (7) successively and in steps is fed in between the web tools (1,2) and successively and in steps is deformed by means of said tools (1,2,3,4).

Abstract: Rod or wire shaped material is produced by substantial reduction of the cross-sectional area of a metal blank in each of two types of alternating, sequentially arranged rolling passes, each of one type of pass being effected by flat-rolling the blank in at least one pair of rolls having substantially smooth roll barrels, and each of the other type of pass being effected by upset-rolling the blank in at least one pair of rolls having grooves which exhibit a rounded groove bottom.

Abstract: There is provided an apparatus for plastic working of material, comprising a lower portion carrying a lower tool and upstanding bars, an upper portion in the form of a carriage mounted on the bars for gliding movement along said bars and carrying an upper tool intended for co-action with the lower tool, cylinder and ram means for displacing the carriage along the bars, and expander sleeves for fixing the carriage to the bars in an optional position of displacement.
