Definitions

  • This invention relates to thread-advancing reels. More particularly itrelates to reels of the interleaved bar member type generally supported only from one end.
  • the reels advantageously can be used for withdrawing and forwarding formed thread without the benefit of a guide for wiping off bath or treating liquids and for determining the initial contact point of the thread with the reel.
  • a withdrawing reel or some, other form of thread take-up device, generally is positioned above the thread-forming means in a viscose thread coagulating bath.
  • the formed thread is withdrawn from the bath by the reel, and the coagulating bath liquid adhering to the thread is shed therefrom generally through the use of a wiper element such as a guide positioned ahead of the withdrawing reel.
  • the bath liquids may be carried by the thread onto the withdrawing reel and permitted to flow therefrom by gravity or thrown off by centrifugal forces.
  • a thread In reels comprising two reel members, Where one is eccentric to the other, a thread generally contacts one of the reel members for a part of the reel circumference and the second reel member for the remainder of the reel circumference.
  • the eccentric positioning of the one reel member relative to the other causes the thread to be advanced in a plurality of generally helical turns, the turns forming a store of thread which may be subjected to a desired chemical treatment.
  • This invention provides for a reel having a construction which eliminates the need of a guide, readily disposes of excess bath liquids, maintains control of thread travel, and which also predetermines a store of thread on the reel.
  • the reel includes a reel member that is grooved substantially to the extent of the eccentric distance from the othe reel member so that a thread placed in this groove resides therein for a part of the circumference of the rotating reel, to be supported later upon rotation of the reel by the second reel member and advanced away from the groove, and along the reel periphery.
  • a further benefit derived from the thread groove is that the thread itself is formed into a more closely compacted bundle, the bath liquids being forced by the compaction to the top of the thread with the further result that a larger liquid accumulation is formed which is more rapidly and easily thrown off.
  • a withdrawing reel having a starting groove which determines a thread take-up position on the reel and provided with a tapered end provides for a determination of a definite store of thread which store is not dependent upon the approximation of an attending operator. Further, the reel is adapted also for use on all subsequent thread treating stages.
  • Figure 1 represents, in plan, the grooved reel of this invention
  • Figure 2 represents in section the reel of Figure l, the section being taken across line 22 of Figure 4;
  • Figure 3 is a partial section of a reel bar including the groove
  • Figure 4 represents the reel of Figure l in cross-section along line 44.
  • Figure l discloses a threadadvancing reel of the type shown in Knebusch Patent No. 2,210,914.
  • the reel comprises two reel members 8 and 9, each of which has a periphery of a plurality of longitudinally extending bar members 10 and 11, respectively.
  • the reel members 8 and 9 are made of rigid construction and their bar members are arranged in an interdigitating relation.
  • the reel members 8 and 9 are supported for rotation by the reel shaft 12.
  • a rotation of the shaft 12 effects a rotation of the reel members 8 and 9 and, because of their eccentric relation, thread is adapted to be advanced lengthwise along the reel in the form of a general helix.
  • the reel is supported from one end by a flange 13 through which extends the reel shaft 12.
  • the flange 13 is adapted Where no intermediate wiping guide is used the to be fastened or fixed against rotation in the face of a spinning machine (not shown).
  • the arrangement of the various component parts of the reel of Figure 1 is shown in greater detail in Figure 2.
  • the reel members 8 and 9 are mounted about shaft 12.
  • Reel member 8 is fixed to the shaft 12 so as to rotate therewith while reel member 9 is supported for rotation about an eccentric sleeve 14 which is attached to the flange 13 and through which the reel shaft 12 extends.
  • the bar members 11 of reel member 9 merge into a ring or flange 23 which is attached or fixed to a complementary flange 24 by bolts 25.
  • Flange 24 forms a part of hub 15 adapted to rotate on spaced bearings 20, 21 positioned about an eccentric sleeve 14.
  • the axis of the eccentric sleeve 14 is offset and askew to the axis of the shaft 12, or to the axis of the reel member 8 which is concentrically mounted on the shaft 12.
  • the eccentric sleeve 14- is also mounted about spaced bearings 18, 19 through which extends the reel shaft 12.
  • the reel member 9 thus rotates about the eccentric sleeve 14 which is held fixed against rotation by the attached flange 13.
  • the shaft 12 rotates within the eccentric sleeve 14 and, through bar to bar contact effects a rotati n of the reel member 9.
  • the bar members 11 of the reel member 9 are transversely notched or grooved at a point where it is desired to withdraw thread from a coagulating bath.
  • the depth of the notch or groove 28 as shown in Figures 2 and 3 is about equal to the amount of offset between the axes of the reel members.
  • the grooves 25 serve as a guide for the thread advanced over the reel.
  • the form of the grooves is generally V-shaped so as to effect a compaction or a bundling of the filaments forming the thread.
  • the two member reel is generally positioned in the face of a spinning machine so that the bar members of one reel member, or reel member 9 in this instance, extend outwardly beyond the periphery of the bar members of reel member 8 for about the upper half of the circumference of the reel (see Figures 4).
  • a thread is laid into the grooves 28 it is carried by them for about the upper half of the reel periphery.
  • the grooved bar members 11 or the grooved reel member 9 upon rotation recedes within the periphery of reel member 3 for the lower half of the reel circumference, and the thread is then supported by the bar members 10 of the reel member 8. Due to the askew relation between the reel members 8 and 9 the thread is advanced away in a normal manner from the grooves 23 and along the reel periphery.
  • a further improvement in handling thread on a reel while it is advanced is effected by similarly tapering the ends of both sets of bars 16, 11 at their ends, the taper being taken at a declining angle toward the center of the reel. While improvements in the handling of thread such as minimizing the formation of ringers or split thread turns have been noted at various tapers of the bar member ends it has been found that a bar member having a taper 30 at an angle of about 45 is most advantageous. The taper 30 tends to prevent the formation of ringers and split thread turns which tend to form at about the let-elf section of the reel. Further, a predetermined store of thread can be placed on the reel of this invention since it is automatically determined at the take-up end by the grooves 28, and at the let-off end by the taper 30 of the bar members 10 and 11. of the reel.
