Abstract

1,021,794. Straightening. DRIAM S.A. Dec. 11, 1963 [Dec. 11, 1962], No. 48963/63. Heading B3E. A method of straightening a laterally curved metal band while it is moving in its longitudinal direction, comprises plastically deforming the band across its entire width in successive steps at longitudinally spaced parts of the band so that the shorter longitudinal edge is lengthened to a greater extent than its longer edge. A metal band or strip is drawn off a reel 2, passed through and stretched between guide units 3, 4 each comprising a pair of rolls, one being spring biased towards the other and then on to a wind-up reel 5. The strip is also laterally guided by rollers 9 and the curvature measured by gauging rolls. A device 11 mounted between the units 3, 4 and reciprocable in the strip feed direction along a track on the machine bed 8 comprises a pair of press bars 12, 13 (Fig. 5, not shown) on which are mounted dies 14 of a circular cross-section. The bars are moved relatively towards one another by hydraulic means 15, 16 so as to plastically deform the strip passing therethrough, in an axial direction, by applying a transverse force across the strip to effect stretching of the concave edge thereof relative to the convex edge. The force distribution across the strip may be controlled by spacers 17, 18 and the unit actuated either automatically in conjunction with the gauging means 10 or manually. During the pressing operation the means 11 may be taken along with the moving strip and upon release retracted to its initial position by spring means.
