Abstract

799,267. Angular bending. KOCKS GES., F. April 17, 1956 [April 25, 1955], No. 11678/56. Class 83 (4). A method of making longitudinal slit tubes from strip comprises feeding the strip between a pair of jaws which together form a pass of gradually decreasing cross-section, the jaws being driven in such a manner as continuously to open and close and simultaneously to advance the strip in steps. Jaws 1, 2 which are carried by eccentrics 3a, 3a<SP>1</SP> and, through links 5, 5<SP>1</SP>, eccentrics 6a, 6a<SP>1</SP>, form a pass of gradually decreasing cross-section. Strip 7 entering the pass is deformed and fed forward a step every time the jaws 1, 2 close, upon rotation of the eccentrics, thus to form a tube. The jaws 1 may have a projection 14, which engages in the slot formed when the strip is bent into a tube, for longitudinally guiding the strip. The jaws may each be made in three parts 8, 9, 10 and 11, 12, 13 of which the intermediate parts 9 and 12 are changed to form a tube of different diameter.
