Abstract: 1,214,638. Re-shaping deformed sheets. NEAGRON (CONSTRUCTION) Ltd. 15 Aug., 1968 [16 Aug., 1967], No. 37788/67. Heading B3E. Apparatus for re-shaping flanges along the edges of sheets comprises one or more pairs of rotatable rollers e.g. 20 and 28 axially displaceable relative to one another, each pair having two axially spaced co-operating pairs of radiallyextending surfaces engageable with one another to limit relative axial displacement of the rollers and to provide a gap between one of the pairs of radially-extending surfaces sufficient for passage and re-shaping of a flange along the edge of a sheet. The lower roller 20 has an annular shoulder portion 49 which comprises a frusto-conical surface 52 above which is a complementarily shaped shoulder portion 53 on the roller 28. The shoulder portion 50 of the roller 20 comprises two frusto-conical surfaces which form a V-section channel above which is a complementarily shaped portion 58 on the roller 28. The axial spacing is such that a sheet is passed in one direction between the rollers 20 and 28 to have one flanged edge re-shaped by one pair of surfaces and then the sheet is returned in the opposite direction to have the opposite flanged edge re-shaped by the other pair of surfaces. On each pass of the sheet the flanged edge which is not being re-shaped lies clear of the radially extending surfaces which limit the relative axial movement of the rollers. The upper rollers 28 and 29 are mounted on a carriage 30 which is guided for vertical displacement in a machine frame by means of laterally spaced guide members. The carriage 30 is formed with a cross member 32 on the upwardly-facing surface of which is a bearing 33 for receiving the lower end of a screw threaded rod 34 engaging a nut 35 in a support bearing structure 36 and a control wheel having two handles 38 for rotating the wheel to give a vertical displacement of the roller 28 and 29. The nut 35 is held in the lower end of the structure 36 by means of two shear pins 43.
