  • PROCESS AND APPARATUS FOR SPINNING STAPLE FIBERS Filed Jan. 4, 1965 2 Sheets-Sheet 3,324,642
  • ABSTRACT OF THE DISCLOSURE A process and apparatus for spinning staple fibers wherein a sliver is continuously delivered to a separation roller where individual fibers are separated from such sliver.
  • the thus separated individual fibers are accelerated by means of an air current approximately to the peripheral velocity of the inner wall of a hollow body member, and then the individual fibers are delivered approximately tangentially to a quickly rotating hollow body member to form thereat a fiber ring, and finally, the yarn is axially withdrawn out of the fiber ring.
  • the present invention has reference to an improved process and apparatus for spinning staple fibers.
  • a continuously delivered sliver or band is separated into individual fibers by means of a rotating separating roll or roller and the individual fibers are transported to the inner wall of a quickly rotating hollow body member, there collected and withdrawn as twisted yarn.
  • the hollow body member rotates at a considerably higher speed than the separating roller. Consequently, it is not possible to prevent that the individual fibers floating in the air current or stream will be grasped by the newly formed yarn before they have assumed thespeed of the hollow body member and have deposited upon the inner wall at the hollow body member provided with bores. They then build curls about the yarn which disadvantageously affect its tying together, its appearanoe as well as its strength.
  • the speed of rotation of the separation roller cannot be increased as desired, because the fibers must be care-fully combed out of the delivered sliver without being torn. A shortening of the fibers would reduce the quality of the yarn to an undesired degree.
  • a further important object of the present invention is directed to an improved apparatus for the spinning of fibers which enables to effectively separate the fibers from a fiber-air mixture so that the quality of the spun yarn is not impaired.
  • Another considerable object of the present invention relates to an improved spinning device incorporating a separation roller and a rotating hollow body member, and means disposed between said separation roller and hollow body member for accelerating a fiber-air mixture approximately to the peripheral speed of the aforesaid hollow body member.
  • the process contemplated according to the present invention incorporates the features of accelerating the individual fibers with the surrounding air-sometimes referred to herein as fiber-air current-during movement from the separation roller to the quickly rotating hollow body member approximately to the peripheral speed of such hollow body member, conducting the individual fibers together with the surrounding air to the inner Wall of the hollow body member, such inner wall being provided with combing means, separating the individual fibers at this location from the entrained air current due to the centrifugal action, collecting and holding the fibers by the combing means until their withdrawal as a spun or completed yarn while deflecting and sucking-off the air current cleaned or freed of fibers.
  • the spinning device of the present invention employed for the execution of the aforementioned process is designed to accelerate the fibers by means of an accelerating roller arranged between a separation member, e.g., separation roller and a hollow body member, the aforesaid acceleration roller can be advantageously provided with air passage means and combing means.
  • the peripheral speed of this acceleration roller is approximately as large as that of the hollow body member.
  • a further possibility for accelerating the fibers is based upon the feature of narrowing the cross-section of a communicating or connecting channel leading from the separation roller to the hollow body member, thereby achieving acceleration of the air current.
  • a further aspect of the present invention concerns itself with the guiding of the air in the hollow body member.
  • the fiber-air current flowing-in with a high velocity is guided to the inner wall of the quickly rotating hollow body member in order to be there deflected, cleaned or freed of fibers and then sucked-off.
  • the individual fibers are thrown by the centrifugal action against the inner wall of the quickly rotating hollow body member, collect in the combing zone until the desired yarn thickness, remain lying there until they are spun onto the yarn which moves further with its withdrawal speed along the inner wall of the quickly rotating hollow body member.
  • FIGURE 1 is a side view in cross-section of the feed roller, the separation roller and the acceleration roller with communicating air channel;
  • FIGURE 2 is a plan view, partly in cross-section, of the acceleration roller, the hollow body member with blower means and the withdrawal rollers of the spinning device of FIGURE 1;
  • FIGURE 3 is a side View of a further embodiment of spinning device showing details of the feed roller, separation roller and a connecting channel having a narrowing cross-section in the direction of the hollow body member;
  • FIGURE 4 shows in cross-section details of the physical structure of an arrangement somewhat similar to FIG- URE 3, yet here incorporating a modified form of hollow body member with a central suction arrangement for a number of spinning devices.
  • a sliver or band 1 is delivered by means of a feed porcupine roller 2 rotating in the direction of arrow C to a separation roller 3 rotating at greater velocity in the direction of arrow D.
  • the separation roller 3 is provided with needles 4 which comb individual fibers 5 out of the sliver 1 and entrain such fibers in its direction of movement.
  • an acceleration roller 6 revolving at a higher velocity.
  • An air channel 7 merges tangentially with an opening 8 provided .at the inner wall of a hollow body member 9.
  • the feed porcupine roller 2, the separation roller 3 and the acceleration roller 6 rotate within a housing which for reasons of fabrication is formed by the housing portion 10 and the cover member 11.
  • the mentioned rollers are driven by shafts which drive a number of spinning devices.
  • the shaft 12 drives the acceleration roller 6, the shaft 1211 the feed porcupine roller 2 and the shaft 12b the separation roller 3.
  • the separation roller 3 and the acceleration roller 6 are advantageously formed of the same members for reasons of fabrication. It will further be seen that such embody both flanges 13 and 13a and the needle runways or arms 14 provided with the needles 4 secured between the aforesaid flanges 13 and 13a.
  • the air channel 7 is disposed in a removable guide member or core 15. Such is laterally secured by a projecting edge or shoulder 16.
  • the hollow body member 9 has its axis substantially parallely disposed with respect to the axes of the rollers arranged in the housing portion 10 and embraces the guide core 15.
  • This hollow body member 9 is rotatably mounted by means of a bearing 19 upon a hollow shaft 17.
  • This hollow shaft 17 in turn is connected at one end in a support 18.
  • the hollow body member 9 is driven contra the direction of rotation of the acceleration roller 6 through the agency of a belt 20. It will also be seen that in the wall of the hollow body member 9 there is located a substantially V-shaped, smooth walled, annular groove 21 for collecting the individual fibers 5.
  • Forwardly directed needles 22 are mounted at the base of the annular groove 21.
  • the compartment 21a surrounded by the annular groove 21 is separated by a frontal wall 24 from the air ducts or channels 23 of the hollow body member 9 functioning as blower means.
  • This frontal wall 24 is provided with an opening 25 through which extends the hollow shaft 17 with a guide disk 26.
  • the feed porcupine roller 2 steadily delivers a sliver or band 1.
  • Individual fibers 5 are continuously combed out of the sliver 1 by means of the needles 4 of the quicker rotating separation roller 3.
  • the thus combed out individual fibers are entrained in the direction of movement of the separation roller 3 indicated by reference character D.
  • the blower action of the air channels 23 generates an air suction current which moves through the intermediate spaces between the needle runways or arms 14 of the acceleration roller 6 and the separation roller 3.
  • This air suction current or stream loosens the individual fibers 5 from the needles 4 of the separation roller 3 and transmits them to the acceleration roller 6 revolving at a very high velocity.
  • the different lengths of the arrows C, D and E signifies that the corresponding rollers move with different high velocities. In reality, the increase of the number of revolutions is larger and a multiple of the previously arranged roller.
  • the peripheral speed of the acceleration roller 6 completely or approximately corresponds to that of the hollow body member 9.
  • the moving needle runways 14 also exert a blower effect, so that the accelerated individual fibers 5 together with the air current are transported via the air channel 7 against the frontal wall 24 and into the annular groove 21 of the hollow body member 9.
  • the fiber-air current fiows with a velocity which completely or approximately corresponds to the peripheral speed of the annular groove 21 against the aforesaid annular groove 21 of the hollow body member 9.
  • this yarn pulls the collected fibers over the backs of the forwardly inclined needles 20 disposed in the annular groove 21, spins these fibers, and continuously removes such as a yarn 28.
  • the yarn 28 is withdrawn without interruption from the hollow body member 9 over the deflecting roller 29 by means of the rollers 27a of the delivery device 27 and then delivered to a non-illustrated winding mechanism.
  • the needles fulfill the function of limiting the extent of twist of the yarn at the beginning of the yarn, in other words, prevent the fibers 5 collected and lying in the annular groove 21 from being twisted by the yarn. Formation of curls upon the individual fibers contacting the spun or completed yarn is prevented in that the individual fibers themselves move with approximately the same speed as the beginning of the yarn in the annular groove 21. Thus, there is no differential speed between the delivered fibers and the withdrawn yarn, so that the individual fibers cannot be grasped by the yarn in the air and curl about such yarn. Due to the acceleration of the fiber-air current the yarn tension is considerably reduced since there no longer appears air resistance in the direction of rotation of the hollow body member 9.
  • FIGURE 3 there is depicted a variant embodiment of inventive spinning device.
  • the feed porcupine roller 2' and the separation roller 39 correspond in function and physical structure to the corresponding rollers 2 and 3 of FIGURES 1 and 2.
  • the acceleration roller is dispensed with by virtue of an appropriate construction of the air channel 31.
  • the housing 30 is also correspondingly constructed.
  • the air channel 7 of FIGURE 1 extends linearly from the acceleration roller 6 to the hollow body member 9
  • the air channel 31 is of ring-shaped or annular construction possessing a cross-section which narrows in the direction of the hollow body member.
  • hollow body member is not visible in FIGURE 3, since it is covered by the guide core 32, yet it will be ap preciated that mounting of this hollow body member corresponds to the embodiment of FIGURE 2. Moreover, the direction of rotation of such hollow body member is opposite the direction of rotation of the separation roller 39 indicated by the arrow G.
  • FIGURE 4 there is depicted the physical construction of an air channel 31, which in this embodiment does not guide the fiber-air current, as in the case of FIGURES 1 and 2 into an annular groove 34 of a hollow body member 35 by means of a limited opening, such as opening 8 of FIGURE 1, rather in this case guides such fiberair current through an annular or ring-shaped gap 33.
  • the air is not conveyed by blower means simultaneously revolving with the hollow body member, rather by means of a separate suction device or blower, schematically indicated at 50, to which a plurality of spinning devices can be connected.
  • the suction stud or nipple 36 leads to this blower 50.
  • the movement of the air is represented by the arrow H. Due to this suction a vacuum appears in the sealed hollow compartment 37, into which vacuum the air current cleaned or freed of fibers is sucked through the openings 38 provided at the hollow body member 35.
  • the remaining function is the same as already described in connection with FIG- URES 1 and 2.
  • the fiber-air current leads from the separation roller 39 into the air channel 31. At this location it is placed into rotation by virtue of the spiral-shaped configuration of such air channel 31 and at the same time is accelerated, due to the narrowing of the cross-section of the aforesaid air channel, to a speed which completely or approximately corresponds to the peripheral speed of the annular groove 34 of the hollow body member 35.
  • the fiber-air current is guided via the annular gap 33 which is open all around into the annular groove 34 of the hollow body member 35.
  • the fibers are separated in the described manner from the fiber-air current, deposit themselves in the needle field 40 and are spun into a yarn 41.
  • the air current freed of fibers is sucked through the openings 38 into the hollow compartment 37 and conducted via the suction nipple 36 to the blower 50.
  • a process for spinning staple fibers comprising the steps of:
  • Apparatus for spinning staple fibers comprising a separation roller incorporating means for separating individual fibers from a sliver, a rotatable hollow body member for receiving the separated individual fibers, means for accelerating the individual fibers by means of their surrounding air prior to delivery to said rotatable hollow body member, and at least one rotatable acceleration roller for contributing to the acceleration of the individual fibers and surrounding air disposed between said separation roller and said hollow body member.
  • Apparatus for spinning staple fibers as defined in claim 2 further including an air channel disposed between said acceleration roller and said hollow body member, said air channel possessing a cross-section which narrows from said acceleration roller in the direction of said hollow body member.
  • Apparatus for spinning staple fibers comprising a separation roller incorporating means for separating individual fibers from a sliver, a rotatable hollow body member for receiving the separated individual fibers, means for accelerating the individual fibers by means of their surrounding air prior to delivery to said rotatable hollow body member, and an air channel for contributing to the acceleration of the individual fibers and surrounding air extending between said separation roller and said hollow body member, said air channel possessing a crosssection which narrows from said separation roller in the direction of said hollow body member.
