Abstract
1,064,147. Making tubing; stamping. LORRAINE-ESCAUT. Dec. 9, 1963 [Dec. 12, 1962], No. 48501/63. Headings B3A and B3Q. [Also in Division E1] A metal scaffolding tube (1, Figs. 1 and 4) of rectangular cross - section comprises flutes swaged at regular intervals in at least one of its faces and extending over at least part of its length. The flutes may be of circular, square or cross formation, or they may extend transversely or diagonally of the tube (Figs. 7-11). A mandrel (3, Fig. 4) carrying dies (8, 8a) for fluting opposite sides of the tube simultaneously when external dies (2, 2a) are closed by a press, has links (4, 4a) with pivots (7, 7a) for the dies (8, 8a). The links (4, 4a) are pivoted at one end (5, 5a) and at the opposite end are interconnected by a spring (6) which allows their separation by a wedge (9) for applying the dies (8, 8a) against the inside walls of the tube. Continued movement of the wedge carries it into backing engagement with the dies (8, 8a). The mandrel could support a plurality of diesets, or long dies could be used bearing a number of imprints. If only one face is fluted, curvature of the tube is produced. It is stated that the flutes could be produced by rolling.
