Abstract

Procedure for the manufacture of a tube elbow, in which a sheet of plastic film is deformed, by means of sausage, giving it a shape that results when the elastic sleeve of a toric sector is cut along its smallest internal circular arc, and then it is opened until a cap or cover is formed that does not have re-entering curves, and the resulting recessed cover-type structure is then converted, by bending or flexing, to the state of the toric sector by an operation that runs inversely to its operation of virtual conformation, characterized by the fact that, before mounting it on an insulation, the sheet of plastic film deformed by opening is subjected to a heat treatment such that the stresses produced by the opening process are reduced to such a degree that the sheet of plastic film retains the state of toric sector without external influence.
