Shaping Of Tube Ends By Bending Or Straightening
(AREA)
Abstract
Improvements in the manufacture of flexible tubes comprising a spiral wound flexible band of adjacent edges welded together, characterized by establishing a reinforcement constituted by a core of circular cross section of thermoplastic material, and of semi-rigid nature, whose core is arranged longitudinally with respect to to said band, being covered with a covering shell of relatively flexible thermoplastic material and the assembly constituting a body whose section extends in at least one fin, which joins the adjacent spiral of the spiral, such dimensions being the indicated body and said fin which, once joined in the form of a tube, the body-like parts of the adjacent turns of the tube, are separated from one another by a distance essentially not greater than the total thickness of said body.
