Abstract

647,515. Tube-making machines. BREMER, R. C. June 21, 1943, No. 17302/48. Divided out of 647,460, under which a Specification was laid open to inspection under Sect. 91 of the Acts, July 31, 1944. Drawings to Specification. [Class 99(ii)] '[Also in Groups XXII and XXXVI] In apparatus for making flexible tubing in continuous lengths from strip material by winding it in overlapping relation on a core, the tube so formed passes through a corrugating tool comprising a rotating core and a surrounding rotating nut, the core and nut having co-operating screw threads of gradually diminishing pitch so as to cause the corrugations to lie in substantially abutting relation on discharge from the tool. The apparatus is described in detail in Specification 647,460. Specifications 647,513, 647,516 and 647,517 also are referred to.
