Abstract
Abstract A method and apparatus are described for producing a transfer tail on precision wound packages with the transfer tail being made at the same speed and under the same conditions as the other textile material placed on the package. The invention is described with specific reference to the winding of fiber glass strand packages. An angular guide is utilized to automatically position the strand or strands over a traversing mechanism guide eye which allows the threading of the yarn in the guide eye without interruption of the normal movement of the yarn or yarns being wound. The system may be manually or automatically operated so that the transfer tail is not applied to the packages until operating speeds are obtained on the textile package to be wound, thus providing for the same character of yarn on the transfer tail as on the subsequently wound yarn.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A method of winding double strand packages to provide tie on tails on each package comprising the steps of introducing two strands to be wound through a guide member and attaching them firmly between two tubes on which the packages are tO be wound positioning a holder in the guide member to maintain the two strands in the guide member, rotating the tubes to commence winding the two strands at their point of attachment between the tubes, upon attaining a given winding speed, releasing the holder from the guide member and directing the two strands away from each other and into reciprocating, transversing guide members associated with each tube, and continuing winding the strands on said tubes until the desired packages have been formed thereon.
Claim 2
Independent Claim
125 words
A method of winding double strand packages to provide tie on tails on each package comprising the steps of introducing two strands to be wound through a guide member and attaching them firmly between two tubes on which the packages are tO be wound positioning a holder in the guide member to maintain the two strands in the guide member, rotating the tubes to commence winding the two strands at their point of attachment between the tubes, upon attaining a given winding speed, releasing the holder from the guide member and directing the two strands away from each other and into reciprocating, transversing guide members associated with each tube, and continuing winding the strands on said tubes until the desired packages have been formed thereon.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein said releasing of said holder occurs automatically upon the attainment of a given speed by the winder.
Claim 4
Dependent Claim
27 words
The method of claim 1 wherein said holder is maintained in place by a magnet and said releasing of said holder is accomplished by deactivating said magnet.
Claim 5
Independent Claim
144 words
A method of winding a plurality of textile packages to provide tie on tails on each of the packages wound comprising providing a guide member for each two packages to be wound, passing two separate textile strands through each guide member and attaching them between the two tubes on which packages are to be wound associated with each guide member, providing a holder in each said guide member to maintain each set of two textile strands positioned therein, rotating the tubes to commence winding packages thereon, releasing the holder from the guide member when the rotation of the tubes has reached the desired winding speed and simultaneously spreading the two strands associated with each guide member away from each other, picking up each strand as it is spread in a horizontally traversing guide member and winding a package on each tube as they rotate.
Claim 6
Independent Claim
144 words
A method of winding a plurality of textile packages to provide tie on tails on each of the packages wound comprising providing a guide member for each two packages to be wound, passing two separate textile strands through each guide member and attaching them between the two tubes on which packages are to be wound associated with each guide member, providing a holder in each said guide member to maintain each set of two textile strands positioned therein, rotating the tubes to commence winding packages thereon, releasing the holder from the guide member when the rotation of the tubes has reached the desired winding speed and simultaneously spreading the two strands associated with each guide member away from each other, picking up each strand as it is spread in a horizontally traversing guide member and winding a package on each tube as they rotate.
Claim 7
Independent Claim
179 words
An apparatus for winding dual packages on winding tubes comprising two tubes adapted to receive textile strand on their respective surfaces and mounted on a spindle associated with a motor adapted to rotate said spindle, means between said tubes for engaging at least two textile strands, a guide member positioned adjacent said tubes and adapted to receive at least two textile strands, a holder positioned in said guide member and adapted to engage at least two strands positioned in said guide member, said holder being provided with a straight pin at the end thereof positioned in said guide member and a bifurcation at the base of the pin, said bifurcation being such that when the pin is moved out of the guide member, it spreads strand held by the pin in a lateral direction, means for moving said holder out of said guide member, and means associated with each of said tubes to receive strand as it is moved laterally by said holder and reciprocate strand in a horizontal plane with respect to each of said tubes during winding.
