Abstract

1440454 Straightening welded sections ITALSIDER SpA 24 July 1973 [24 July 1972] 35188/73 Heading B3E A method of straightening welded compound sections comprises guiding the section through rollers which are positioned so as to produce a distortion opposite to an original distortion in order to plastically deform the section to move the original distortion, the rollers being spaced apart so as to minimize shearing force on the section. Apparatus for straightening the sections comprises a central section-feeding roller unit 1, Fig. 1, and section-straightening roller units comprising horizontally and vertically mounted rollers 4, 5 and 9, (10), respectively, Fig. 2 (not shown), at both the inlet and outlet of the central roller unit, the distances of the sectionstraightening units from respective ends of the central unit being substantially equal to the length of the central roller unit. Rollers 2, 3 of the central roller unit are provided with grooves and include rolls 2<SP>1</SP>, 3<SP>1</SP>, Fig. 4, discs 211, 3<SP>11</SP> and separators 20, 30. Rollers 9, (10), (11) are mounted on movable slides and are responsible for removing planar distortion of the sections. The separator width may be altered to accommodate sections having parts of various thicknesses.
