US 6,237,866 B1 · Yarn unwinding tension stabilizer and a yarn unwinding tension stabilizing apparatus for a warping creel using the same

Abstract

A yarn unwinding tension stabilizer capable of stably unwinding a yarn from various types of yarn suppliers in such shapes as cheese and cone so as to effectively cope with such drawbacks as slide of wound layers on a yarn supplier and slippage of yarn loops therefrom due to the ballooning of an unwound yarn and so forth and a yarn unwinding tension stabilizing apparatus for a warping creel capable of simultaneously setting said stabilizers on the multiple number of the suppliers suspended on the warping creel in an easy operation. The tension stabilizer (3) is arranged by disposing the plurality of elastic wiring materials (2) on the opening (10) of the supporting member (1) in such a manner that said materials convavely curve towards the center of said opening and overlap one another. The frame, in which the plurality of said stabilizers are aligned in rows, is arranged such that it is horizontally movable as a whole.

Dependent claims

A yarn unwinding tension stabilizing apparatus for a warping creel, which is disposed opposed to a plurality of pegs (P) aligned in rows in the creel and which stabilizes tension acting on a yarn (Y) unwound from the respective yarn suppliers (B) suspended on said pegs (P), said stabilizing apparatus comprising:

a plurality of tension stabilizers (3) respectively made of a supporting member (1) provided with an opening (10) of a diameter and a plurality of elastic wiring materials (2) disposed within said opening (10) wherein the respective wiring materials (2) are fixed at both ends thereof on the periphery of said opening (10) while partly overlapping one another and an unwinding area (20) is formed at a center, which is enclosed with those overlapped wiring materials (2);
a frame (5) supporting those tension stabilizers (3) in alignment with yarn suppliers (B) suspended on said pegs (P);
and
a means (6) to horizontally move said frame (5) so as to make said tension stabilizers (3) simultaneously approach to or retract from said yarn suppliers (B).
