Abstract

927,980. Making pipes; sheet metal joints. SVENSKA FLAKTFABRIKEN A.B. Jan. 4, 1962 [Jan. 5, 1961], No. 388/62. Classes 83 (2) and 83 (4). [Also in Group XXVIII] A method of manufacturing pipes from helically-wound band or strip the edges of which are folded together and pressed to form a helically-extending joint is characterized in that during the pressing operation regularly spaced point-like impressions are made in the joint for securing the folded edges of the band or strip to one another. The helical joint 2 is pressed between rollers 3 and 4 the roller 3 being provided around its periphery with a plurality of conically-headed pins 5 which produce the impressions or notches 6 in the joints.
