Definitions

  • FIGURE 4 is a section along line 4-4 of FIGURE 2 showing details of the suction box used to evacuate the hollow, spinning spindle of FIGURE 1;
  • FIGURE 9- is a section along line 9--9 of FIGURE 2 showing the false-twist device.
  • Suction box 1 fitting loosely around spindle 3 is equipped with anti-friction air seals 15 and 15a.
  • Said suction box is floatingly mounted by conventional means in axial alignment with spindle 3.
  • a close-fitting, smooth-flanged set collar 18 is rigidly held to spindle 3 by set screw 19 at a position to maintain alignment between annular hollow 16 and spindle evacuation holes 13 when air seal 15 bears against the smooth flange of collar 18.
  • a second, close-fitting, smooth-flanged collar 2i slides freely on spindle 3 with its flanged face bearing against air seal 15a.
  • Housing 23 is a block-like structure bored transversely for a clearance fit on spindle 3. Its front face is recessed to a depth equal to the axial width of screened opening 11 in spindle 3. The shape of said recess is substantially circular with its center displaced bias-wise relative to the center of spindle clearance bore 23. Two tangential channels of the same depth as the circular recess extend into said recess at two adjacent sides of the housing. One of these channels serves as the fiber entry port 25 and is no wider than the length of roving delivery roll pair 6, 6a with which it is aligned.
  • roving strand 1 drawn from conventional bobbins is fed to input roll pair 4, 4a of a conventional drafting system comprised as shown of roll pairs 4, 4a and 6, 6a and apron pair 5, 5a. Passage of the roving strand 1 through the drafting unit attenuates the strand reducing it to a thin ribbon of substantially parallel fibers which are drawn by suction into entry port 26 of housing 23. Suction at port 26 results from the combined evacuation of spinning spindle hollow 1t) and spinning zone Z which creates a pressure-ditferential across port 26.
  • the uniformity of yarn made with this invention is a direct function of the uniformity of the roving fiber feed to spinning spindle 3. Constant speed of roving delivery roll pair 6, 6a is not of itself sufficient for maintaining uniform roving delivery under conventional drafting conditions. Because interfiber friction exists within the attenuated roving strand, individual fibers are not drawn to spindle 3 as soon as they are free of the grip of rollpair 5, 6a. Instead, it is normal for these fibers to cling to fibers still held by said roll pair until the constant flailing by yarn end 7a dislodges them as a bundle which is then picked up by screen 12 to be made into an increment of yarn. There follows a brief interval of no fiber pickup until the next bundle is ready to be dislodged.
  • the yarn made is characterized by periodic variations in diameter in keeping with the intermittent delivery of roving fiber bundles. Consequently, in the interest of yarn uniformity, it is preferable that the roving fibers be fed as individual fibers at a sufiiciently fast rate to maintain the desired yarn size. For example, where conventional spinning calls for a maximum draft of 40:1, it would be preferable with our invention to use a draft of about 200:1 with no change in either, yarn size or yarn production. Although roving draft is much higher the fibers are delivered at a faster rate to the spinning spindle while the yarn is withdrawn therefrom no faster than is done in conventionm spinning.
  • Friction between yarn 7 and passageway 9 alfects the free runback of twist to screen 12 to some extent interfering with the efficient intermingling between roving bers and yarn end fibers.
  • This friction effect may be overcome by utilizing false-twist device 33 to put suflicient additional twist in yarn 7 that the twist runback forces exceed those due to friction.
  • yarn 7 emerging from the end of spindle 3 is first snubbed with one loop 712 around the free arm of rod 31, then threaded through passageway 34 and finally fed to the nip of yarn delivery roll pair 33, 33a for delivery to a winding mechanism, not shown.
  • Suction is not the only medium that may be so employed.
  • screen 12 on spindle 3 may be replaced with a porous medium as such as felt, ceramic, sintered bearing material, etc., rigidly attached to spindle 3 and projecting above the surface thereof.
  • Said porous element comes in rolling contact at some point during its cycle of rotation-preferably at a point directly under the point of entry of the attenuated roving strand into spinning zone Z-with an idling roller 37 rotatably mounted within the aforementioned circular recess in housing 23.
  • a spinning machine for preparing spun fiber yarn from staple length fiber comprising in combination a cylindrical essentially hollow rotatably mounted spinning spindle, means for supporting and means for rotating the spinning spindle about its center axis, means for advancing unspun fiber to an area on the outer curved surface or" the spinning spindle defined as the spinning zone and means for withdrawing spun fiber yarn from an end of the spinning spindle, a smooth surfaced idler roll rotatably mounted and supported in free rolling contact with the spinning zone of the spinning spindle, liquid container and conduit means to supply the interior of the spinning spindle with a liquid; said spinning spindle comprising a hollow cylindrical rotor capped at one end and having the other end open, the open end communicating with said liquid container and conduit means, communication between the hollow interior of the rotor and the outer surface of the rotor within the spinning zone provided by a porous pad capable of transmitting and being wetted by the liquid inside the hollow rotor; said porous pad occupyin at least 45 of are on an outer circumference of the
