Yarn storing device

Abstract

Abstract RETARDING RING FOR A YARN STORAGE DEVICE. AN IMPROVED RETARDING RING IS PROVIDED FOR A PRESENTLY KNOWN YARN STORAGE DEVICE WHEREIN YARN FROM A SOURCE IS MOVED TANGENTIALLY ONTO A STORAGE DRUM AND IS THEN DRAWN AXIALLY FROM THE DRUM. MEANS ARE PROVIDED ON THE DISCHARGE PORTION OF SAID DRUM FOR RETARDING THE WITHDRAWAL OF SAID YARN AND THEREBY PROVIDING TENSION THEREON. THE PRESENT INVENTION CONSISTS IN AN IMPROVEMENT IN SUCH RETARDING RING WHEREIN A RING SURROUNDS AND IS SPACED FROM THE DRUM AND IS PROVIDED WITH FINGERS PROJECTING FROM THE RING AND INCLINED BOTH TOWARD THE DRUM AND CIRCUMFERENTIALLY. IN THE PRESENT INVENTION SAID FINGERS IN ONE EMBODIMENT ARE CURVED IN SUCH A MANNER THAT WHEN THE RING IS WITHDRAWN FROM THE DRUM THE FINGERS PROJECT INTO AN IMAGINARY CYLINDER CONCENTRIC WITH THE RING OF A DIAMETER EQUAL TO THE DIAMETER OF THE DRUM. IN ANOTHER EMBODIMENT SAID FINGERS SIMILARLY PROJECT INTO SUCH AN IMAGINARY CYLINDER BUT THEN ARE REVERSELY CURVED SO THAT THEIR TIPS ARE OUTSIDE OF AND SPACED FROM SUCH CYLINDER. IN BOTH EMBODIMENTS THIS PROVIDES AN INCREASED ZONE BY WHICH SUCH FINGERS CONTACT THE YARN BEING WITHDRAWN AND THEREBY APPLY A MORE UNIFORM TENSION THERETO THAN WAS PREVIOUSLY POSSIBLY.
