WO'UND PACKAGE .AND METHODIOF vPRVIODYUCING THE SAME.

"'Applicanon'mea November e, 192e. seriainallassli'.

Tubular packages which vare intended kto be `dyed by alternate endwise compression and expansion in Vthe dye bath, asby the Well known Franklin process, vhave heretofore been woundof approximately the same density' throughout, with' the exception of Vthe s ends of the package Which were necessarily Wound harder because of the greater pres- Y sure ydue to the reversal of the Winding and consequent accumulation of the yarn at said ends.

portions were endwise compressed in the process of dyeing, the ends became still harder and obstructed the thorough penetration of the dye, With the consequent result of an uneven` dyeing of the package.

Theobject of my inventionisl to produce va tubular package which will be capable of being evenly dyed throughout. To accom-V plish this object Vthe package is Wound so that it Will normally be of greater density at its middle portion than at its end portions and, when compressed endWise inthe dyeing process, Will be of substantially the same y densitythroughout. This result is obtained 'by providing means for so moving the traverse guide for theV yarn that the movementk of the guide will be gradually increased as V 4the guide moves away from the middle portion to the limits of its travel and Will be gradually 'decreased as the guide moves from the limitsof its travel to the middle portion.

the traverse guide 6 is is movedlfrom the limiter the' middle' per:

tion of its travel, so'that the package Willf'be Wound With'a greateridensity at itsmiddle portion'tha'n at Aits ends. 1

In the present instance this variablemove ment of thetraverse guide 6 is accomplished n by so vshaping the groove .71 of the guide reciprocating cam 8 that'it Will have gradually increased pitches .from its center lto.-

Ward both ends, thereby causing thetraverse guide to move faster at'both extremities of its 'traverse Vand slower at kits mid-traverse `The Wound package Vvvill thus normally have a greater density'at-I itsmiddleportion plished with the ends softer than the middle thereof. Y s

I have found that a, package Wound as above described will, When subjected toV the alternate endvvise compression and expansion in the die bath,evenly andl rapidly ab- L sorb the dye, thereby .ensuring a better product in a lesser time than has been possible stantially the same diameter from end to endv and having a harder middle portion and softer end portions. t
