Abstract
In a double twist spindle assembly of the type including a central spindle having a bore therethrough and extending through a can, the spindle supporting within the can a lower yarn package and an upper yarn package each feeding yarn into the bore of the spindle above the packages, an improved device for guiding the yarn which is unwinding from the lower package to prevent its contacting the upper package comprising a disk between the packages and a corrolla device supported on the disc to guide the yarn from the lower package away from the upper package, and the corrolla device comprising plural interlaced leaf members which lie against the upper package and follow its shrinking diameter so that the corrolla automatically shrinks in diameter as the yarn is used up.

In a double twist spindle assembly of the type including a central spindle having a bore therethrough and extending through a can and the spindle supporting within the can a lower yarn package and an upper yarn package each feeding yarn into the bore of the spindle above the packages, an improved device for guiding the yarn which is unwinding from the lower package to prevent its contacting the upper package, the improved device comprising:
- (a) a disc supported on the spindle radially disposed between the packages;
- (b) multiple leaf means pivotally supported on the disc and including outer peripheries extending from the disc and operative to contact the yarn as it unwinds from the lower package and guide it outwardly away from the periphery of the upper package;
- and
- (c) the leaf means having means maintaining contact with the outer periphery of the upper package and operative to close the leaf means to decrease the diameter of its periphery independently of the tension of the yarn as the diameter of the outer yarn layer of the upper package decreases.
