Abstract

1425778 Converting circular section tubing to rectangular section NOKIA AB OY 20 Dec 1973 59211/73 Headings B3A and B3J Tubes 4 of round section are converted to rectangular section by an expanding mandrel 2 comprising two longitudinal members 5, 6 relatively movable perpendicularly to the longitudinal direction of the mandrel, and four laths 12 pivoted on the members 5, 6. An initial deformation is given to a tube by rolls 18 on the mandrel as the tube is pushed on to the mandrel by an hydraulic jack 14. Further jacks 7, 8 now raise the top member 6 for straightening the sides 4a and, upon pivotal movement of the laths 12 against return springs 13, the top and bottom 4b. Thus all sides are straightened by stretching beyond the yield point. In a modification, Fig. 5 (not shown), the laths (21) have contact rods (24) and are carried by finger-strips (20). Adjustment screws (23) and openings (22) are provided. The initial tube has a helical seam and may have a rigidifying helical formation between the seam convolutions. Reference has been directed by the Comptroller to Specification 1,035,812.
