ABSTRACT:
A coupling and support device for a tube used during an unrolling and coiling process for fiber strands. The device includes a cylindric body containing, on its upper part, a screwed peg, rotatively mounted by a bearing, a lamellar spring attached by a rivet, windows and a vertical groove located on a surface, at the lower end of the body, where there are four internal rabbets and four openings, equally spaced, for retraction and expansion of the four tongues. An activator is mounted in a sliding way in the interior of the body and has upper rims, a rotating selector with a longitudinal salience which is attached to the activator by a peg, at the lower end of the activator, where there are four grooves, equally spaced, for the housing of the tongues, kept in their correct position by a ring-shaped spring mounted in a cylindric depression. The retraction and the expansion of the tongues are originated by the angular movement of the selector.
