Abstract
Conical tubes stored in a nested stack are separated one-by-one for supply to an associated textile machine or the like by a separating apparatus having two gripping ring assemblies arranged to respectively surround the last-nested and penultimate tubes of the stack, the gripping ring assemblies being arranged for relative rotation in opposite directions and relative axial movement to separate the respective tubes, each gripping ring assembly including a plurality of gripping elements pivotably movable radially into and out of peripheral gripping engagement with the respective tubes in the manner of a ratchet brake, the gripping elements being arranged to exert an increasing force of gripping engagement with the respective tubes until relative rotation thereof occurs.

Apparatus for separating individual conical tubes from a plurality of nested conical tubes, comprising:
- means for selectively gripping a last-nested one of said tubes, and
- means for selectively gripping the penultimate one of said tubes nested with said last-nested tube,
- said last-nested tube gripping means and said penultimate tube gripping means being relatively arranged for relative rotation in opposite directions for loosening said last-nested tube and said penultimate tube from one another and for movement axially with respect to one another for axially separating said last-nested tube and said penultimate tube,
- each said gripping means including a gripping ring for disposition annularly about the associated tube to be gripped and a respective plurality of gripping elements movably supported on said gripping ring for movement into and out of gripping engagement with the associated tube to be gripped in relation to rotation of said gripping means, said gripping elements being arranged for increasing force of gripping engagement with the associated tube to be gripped until relative rotation occurs between said last-nested tube and said penultimate tube.
