Abstract

1398945 Making pipe fittings E ROTHENBERGER [trading as ING EDWIN ROTHENBURGER SCHWEISSTECHNIK UND INDUSTRIEBEDARF] 20 Sept 1973 [26 March 1973 13 June 1973] 44284/73 Headings B3A and B3J In a tool for flanging a hole in a hollow body and comprising a hooked screwthreaded former 4 and a co-operating screwthreaded thrust member 12, V-grooves 18 increase the bearing area of the tool on the body to be flanged. Opposed flats (19, 20), Fig. 4 (not shown), may reduce the flange 14 to facilitate insertion of the former in the hole. The grooves 18 may be in the flange 14 or provided between cast elements attached to a plane flange.
