<p>A process and apparatus for the on-line realization of the drawing and warping steps of mono-filament threads (10) from polyamide comprising a first pre-tensioning step (4-4a; 6-6a-6b) of the mono-filament threads unwinding from cheeses positioned on a creel, by passage through a tension compensator for said threads, and a drawing step on a plurality of rolls (11-13, etc.) arranged by groups, each group being spaced with respect to the other one. Each group of rolls is contained in a separator-container (7-9) and, at the outlet of the threads from each group, they are positioned on a thread-guide-reed (18-18a-18b) and an ionizing bar (19) for the elimination of the electrostatic charges accumulated by the threads on their translation on said rolls. The plurality of simultaneously treated threads provides for a number of about 1200 threads kept spaced from one another by a value of between 1.4-1.6 mm.</p> |
