(Cl. 28-21) This invention relates to a yarn package suited for processing in standard dyeing equipment and more particularly to a package wherein the yarn Vis packed in .the form of an annular mass in successive helical layers.

An object is to provide a package of the above type having novel and improved characteristics.

Another object is to provide a yarn package wherein the yarn is maintained under tensionless conditions during the processing step.

Another object is to provide suitable apparatus for making such a yarn package.

Various other objects and advantages will be apparent fas the nature of the invention is more fully disclosed.

In accordance with the present invention the yarn is fed by suitable means such as by an air nozzle in the form of overlapped turns or coils into the annulus between an outer cylindrical can wall and an inner core tube. The can is rotated and advanced axially with respect to the nozzle so as to lay the yarn in a series kof helical layers in Ithe annulus. After filling the can iscovered to retain the yarn and may be placed in a standard vat d-yeing machine wherein Atreating fluid is passed through the mass of yarn. Due to the manner is which the yarn is laid in the can it is maintained tensionless and may adjust itself to any degree of shrinkage without increase in yarn tension. After processing the yarn may be withdrawn from the package and wound onto a spool or cop in the usual manner.

The nat-ure of the invention will be -better understood from the following description, taken in connection with the accompanying drawings in which a specific embodiment has been set forth for purposes of illustration.

Refer-ring to the drawings more. in detail, the apparatus is shown as comprising a base plate 10 carrying a center post 12 and having a downwardly extending bracket 13 to which is secured` to a motor y14. The motor 14 has a vertical sha-ft 15 carrying a sprocket 16 which is coupled by a chain 17 to a larger lsprocket 18 pinned on a shaft 19 which is journalled in a boss 20 carried by the base plate 10. A support disc 26 has a hub 27 pinned to the shaft 19 and resting on a boss on the. top of the base plate '10.

Pice

The support disc 26 has an annular recess .28 in which the lowerfbeaded edge of an annular can 'wall 29 is seated. An extension wall 30 is formed with a bottom shoulder 31 tting over the top edge of the can wall 29. The extension wall 30 carries a series of eyes 32 which are engaged by the top ends of spring hooks 33, the lower end-s of which are adapted to hook into an annular groove 34 in the under side of the support disc 26 for securing the can wall 29 and the extension wall 30 in place on the disc 26.

EA sleeve 38 is splined onto the `shaft 19 for `axial movement by roller bearings 39 riding in grooves 40 in the shaft 19 so that `the sleeve 38 rotates with the shaft 19 but is slidable axially thereon. The sleefve38 has a closed top end 41 which carries Ia swivel hook 42 for the purpose to be described. A core tube 43 carrying a bottom flange 44 lits over the sleeve 38 and is rotated therewith. The core tube 43 has perforations 45 and is adapted to forni `the inner core of the package. The bottom .disc 44 has a sliding fit wit-hin the can Wall 29 and is adapted to form the .bottom of the finished package. The can wall 29 has

nperforations

4,6 for ythe passage of treating fluids through the package. 'In its lower position the disc 44 rests on the top surface of the support ldisc 26-and on the inturned peripheral bead of the can Wall 29. The kcore tube 43 lcarries vat its upper end a rin-g 47 having a shoulder 48 on which a core tube extension 49 seats. The core tube vextension 49 is removably mounted over the sleeve 38 with its upper end projecting slightly above the top of the extension wall 30.

An arm 55 is journalled between thrust bea-

rings

56 and 57 carried by a `sleeve 58 which is slidably mounted on the post 12. The sleeve 58 carries a rack 59 meshing with a pinion 60 journalled in ears 61 on the post 12. A crank '62 is connected to turn the pinion `60 for raising and lowering the arm 55. The arm 55 carries a vertical bracket `65 having at its upper end a boss 66 in which is journalled a shaft 67 carrying at one end a feed roll 68 and at its other end a bevel gear 69. A cooperating feed roll 70, shown in FIG. 2, is mounted Ion a shaft '71 journalled in a second boss 72 on the bracket 615. A vertical shaft 7'5 is journalled in a boss 76 on the arm 55 and carries at its upper end a bevel gear 77 meshing with the bevel gear 69. At its lower end the shaft is journalled in a boss 78 carried by the vertical bracket 65. The shaft 75 carries a pulley 79 and is co-nnected to the arma- .ture shaft of a motor 80 which is mounted o-n a bracket 81 carried by the bracket 65.

A yarn tube 85 is carried by the arm 55 with its upper end adjacent the bite of the

feed rolls

68 and 70 to receive the yar-n therefrom. An Vair tube 86 communicates with the side of the yarn tube 85 in a direction to feed the yarn downwardly. A rotating feed tube 87 is journalled in a boss 88 on the bracket 65 in registration with the lower end of the yarn tube 86. The feed tube 87 carries a pulley 89 driven by a belt 90 from the pulley 79. The lower end of the feed tube 87 is curved to form a yarn discharge nozzle 92 extending outwardly at an angle of about 45 degrees from the axis of the tube. A split annular cover plate 95 is carried by a rod 96 from the arm 55. The cover plate 95 lits in the annulus between the core tube extension 49 and the side wall extension 30 and extends helically to conform to the pitch of the yarn layers to be laid in the annulus and to form a vertical `opening 97 between the vertically displaced Ileading and trailing ends of the cover plate 95. The lower trailing end of the helical cover plate is cut away to form ngers 99 over which the yarn slides into the opening 97 in the manner to be described. The rod 96 may be adjusted in the arm 55 for adjusting the height of the cover plate with respect to the yarn tube 87. A series of pins 100 is carried by the disc 44 toV grip and distribute the yarn over the surface of the disc 44 at the beginning of the lling operation.

For space dyeing, the yarn as it is laid in the container, a dye housing 130 may be carried by the cover plate 95 at a point in advance of the fingers 99. The housing 130 may be divided by a wall 136 into two

compartments

131 and 132 which communicate with the yarn annulus by a series of holes 133. Dye may be supplied to the

chambers

131 and 132 through tubes 134 and 135 respectively, which lead to a source of dye, not shown. The same or diiferent dyes may be supplied to the two chambers depending upon the effect desired.

A cop support 102 is carried by the bracket 65. This support carries a cop 103 from.which yarn 104 is fed through eyes 105 to a trumpet 106 terminating adjacent the bite of the feed rolls 68 and 70.

The arm 55 extends beyond the post` 12 and carries a boss 107 in which a rod 108 is adjustably secured by a set screw 109. The rod 103 carries at its lower end a U-shaped shoe 110 adapted to fit in the annulus between the core tube 49 and the can Wall 30.

A counterweight 115 is hung from a cord 116 which passes over grooved rolls 117 carried by an arm 118 lixed to the post 12. The end of the cord 116 is attached to the swivel hook 42 so that the core tube and associated parts are held in their upper position by the counterweight 115. Y

An air tube 120 is connected to the air tube 86 and to a Valve 121 mounted on a bracket 122 carried by the arm 55. An air supply pipe 123 is connected to the valve 121.

A cover plate 1725, as shown in FIGS. and 6, is adapted to be placed over the core tube extension 49 after the can has been filled and the helical cover 95 removed. The cover plate 125 carries a spring clip 126 which is adapted to snap into a groove 127 in the ring 47 to form a top closure for the can as shown in FIG. 8.

In setting up the above apparatus the can wall 29 with the core tube 43 and bottom disc 44 therein is placed on the support disc 26, the core tube extension 49 is placed over the sleeve 38 and seated on the core tube 43 and the extension wall 30 is seated over the can wall 29 and secured by the latches 33. The arm 55 is then turned to bring the helical cover 95 over the annulus between the can wall and the core tube and is brought into a position slightly below the top edges of the wall extension and the core tube extension. The cord 116 is then attached to the swivel hook 42 on the sleeve 38 so that the counter weight 115 raises the core tube until the bottom disc 44 with its pins 100 engages the under surface of the helical cover 95. The motor 80 is started to drive the feed rolls 68 and 70 and to rotate the feed yarn tube 87 and the air valve 121 is open to cause the yarn to be fed along the yarn tube 85 and to be discharged from the rotating nozzle 92 and laid in the form of a succession of overlapped loops on the fingers 99 of the helical cover 95. At the same time the motor 14 is started to cause slow rotation of the support disc 26 and of the can parts which are carried by the support disc. The yarn loops are projected into the opening 97 in the helical cover 95 and are also carried by the pins 100 through the opening 97 and under the helical cover 95. The pins 100 may of course be replaced by other types of friction surfaces which would strip the yarn from the ngers 99. The layer of yarn thus laid is compacted by the helical cover 95 as it advances and is progressively depressed by the contour of the cover to lower the disc 44 against the force of the counterweight 115. The pressure of the layer of yarn against the helical plate is adapted to depress the core member and the bottom member against the force of the counterweights for laying the layer of loops in the form of a helix extending from the top to the bottom of the annular space.

For space dyeing, dye is supplied through the tubes 134 and 135 to the

chambers

131 and 132 and through 4 the holes 133 in the cover plate 95 at a rate to impregnate at least the surface layer of yarn. When the yarn package is treated to set the dye a random variation in effect is obtained. This effect is enhanced by supplying different dyes through the

tube chambers

131 and 132. A uniform effect may be produced by supplying the dye ata rate to impregnate the yarn uniformly throughout the crosssection of the yarn layer. Successive layers of the yarn are laid in the form of a helix in the annulus until the can is filled and the bottom disc 44 is brought into contact with the support disc 26. At this point automatic stop means may be provided to stop the operation of the motors. Such stop means may be controlled, for example, by the position of the counterweights 115.

At this point the operation is stopped, the arm 55 raised to lift the helical cover from the can. A cover ring 125 (FIG. -7) is then placed over the yarn, the arm 55 turned to bring the shoe 110 over the plate 125 and lowered to depress and compact the yarn until the spring clip 126 on the cover plate 125 snaps into the groove 127 in the core tube ring 47. The coverplate is thus locked in place to close the package. The shoe is then withdrawn, the core tube extension 49 removed and the latches 33 released and the wall extension 30 removed to leave the can consisting of the wall 29, core tube 43, bottom disc 44, and cover plate with the compacted yarn in the annulus therebetween, as shown in FIG. 8.

The yarn package may now be processed in a vat dyeing apparatus of standard type adapted to force a treating fluid through the package. During this processing the yarn is in tensionless state and is free to shrink without introducing tension.

After processing the cover plate 125 may be removed and replaced by -a pair of concentric rings 137 as shown in FIG. 9 adapted to hold the yarn compacted and to form an annular space therebetween through which the yarn can be removed for rewinding. The concentric rings hold the yarn in compacted state during the withdrawal from the package andprevent the yarn from tangling or knotting as it is withdrawn.
