Shaping Of Tube Ends By Bending Or Straightening
(AREA)
Abstract
Tube for treatment of synthetic filament, characterized in that it comprises a wide central strip, which is determined between the zones of the mouths, in which there is provided a succession of through holes and a plurality of longitudinal grooves made with its cleft towards the inside of the tube, which grooves act by closing to elastically decrease the circumference of the central sector, oppressed by the uniform radial pressure in the retraction of the wound filament, and the mouths being devoid of holes and grooves, to ensure the persistence in the section circular whatever the diameter in the central strip.
