Abstract

701,369. Making electric conductors. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. Nov. 19, 1952 [March 7, 1952], No. 29277/52. Class 83 (2). [Also in Groups XXVIII and XXXVI] A tubular conductor is formed by longitudinally bending a metal strip having a narrow plane margin 1 bounded by regularly-spaced, stampedout portions 2, the extremity of each of these portions lying nearest to the margin being forced out of the plane of the strip to form perpendicular surfaces 3, the other margin 4 being shaped so as to cover margin 1 and contact surface 3 when the tube is formed. The completed tube is enclosed in armouring or sheathing 6.
