摘要

Perfections in the special spindles for coating rubber threads, which are characterized by fixing the guide or conductive spider of the thread with which the rubber filament is covered, at the end of a radial arm directly joined by welding with the central and crazy ring of an axial, single or double ball bearing, placed in the upper part of the cover wire spool holder; this ring goes crazy around the central spike, perforated, through which the filament to be coated passes.
