Definitions

  • a movable guide means is positioned approximately midway between two yarn winding zones of the winding device to hold the two yarns together as they are put on the winding device.
  • the guide is moved clear of the yarns releasing same after'the yarns are connected to the winding device.
  • the yarns are preferably wound on two cores or tubes detachably fitted on the winding device so as to form a butt joint between adjacent tube ends in the region in which the yarns are initially wound on the winding device, this region being defined by the movable guide means.
  • the yarn reserve to each yarn package is connected to the leading end of the next following package so that any desired number of yarn packages can be subjected to further processing in a continuous operation without need to interrupt the process for a change from one package to the next. For this reason, the yarn reserves must be free of faults just as the yarn in a portion of the package.
  • the two package-winding zones are suitably formed by two tubes or winding cores. which are detachably mounted on the bobbin-winding apparatus and which at their confronting ends have annular peripheral recesses or are bevelled in mirror symmetry at their confronting ends to form a common recess. This recess or recesses form catching grooves for engaging the yarns as they are put on.
  • FIG. 1 is a diagrammatic side elevation showing a bobbin-winding apparatus
  • FIG. 2 is a top plan view showing a thread guide as viewed in the direction of the arrow Pfl in FIG. 1, and
  • FIGS. 3 to are longitudinal sectional views showing the two abutting ends of two yarn packages.
  • the bobbin-winding apparatus shown in FIG. 1 serves to wind up the two yarns l and 2 and comprises an arbor 3, on which two yarn tubes 4 and 5 are detachably fitted.
  • the two yarns 1 and 2 are wound on the tubes 4 and 5 to form yarn packages 6 and 7.
  • the winding means are driven by a common drive roller 8, which is rotated by a motor, not shown.
  • the roller 8 contacts the yarn packages 6 and 7 under pressure and is rotated at a constant speed to ensure a winding of the packages at a constant peripheral velocity as the radius of the packages 6 and 7 increases during the winding operation.
  • the two yarns l and 2 are formed in known manner, not shown on the drawing, in that sets of filaments spun from spinnerets are combined.
  • the filaments may consist of any of a large number of synthetic thermoplastics, of which polyester is frequently used example. When the filaments have been spun, they are combined in bundles, each of which forms a yarn.
  • the yarns Before the yarns l and 2 are moved through stationary annular guides 9 and 10, the yarns may have moved through different pretreating stages and. e.g., one or more galettes. It is difficult to put the two yarns 1 and 2 simultaneously on the associated tubes 4 and 5, which are still empty and rotate at the full peripheral speed of, e.g., 3000-6000 meters per minute.
  • the tubes 4 and 5 are rotated by the motor-driven roller 8, which is in pressure contact with the tubes.
  • the arbor 3 fits the tubes to rotate with them and is generally not driven by other means.
  • the yarns l and 2 are guided along the two convergent dash-dot lines la and 2a and are pulled together through a thread guide 11.
  • the thread guide is shown in a top plan view in FIG. 2 and to hold the two yarns together is provided with a slot 12, which merges into a divergent outlet 13.
  • a push rod 14 is secured to the thread guide 11 and cooperates with a pneumatic or electromagnetic apparatus 30 by which the thread guide can be reciprocated in the direction of the double arrow Pf2.
  • the thread guide 11 may consist. e.g., of ceramic material or of hard-chromium-plated brass; alternatively. the thread guide 11 may consist of a U-shaped member of hard-chromium-plated wire in the form of a U- shaped member having a slot 12, an outlet 13, and a push rod 14.
  • the thread guide I1 is disengaged from the two yarns. This accomplished in the simplest manner in that a switch is actuated to initiate the operation of a pneumatic or electromagnetic pulling device which pulls off the thread guide.
  • the direction of movement of the thread guide 11 is at right angles to the plane of the drawing of FIG. I.
  • the yarns which are tensioned because they have been connected to the bobbin-winding device slip out of the slot 12 and toward the enlarged outlet 13.
  • the yarns move outwardly along respective curves defined by the outlet 13, they move apart in mutually opposite directions because they are tensioned; as a result, the yarns move toward the respective package-winding zones and at the same time are further wound up on the tubes 4 and to form helices 1b and 2b, which constitute the desired yarn reserve.
  • the velocity at which the threaded guide 11 is pulled off and the configuration of the curves of the outlet 13 may be selected to vary the number of turns per inch of the yarn reserve.
  • FIGS. 3 to 5 are longitudinal sectional views taken through the abutting end portions of such tubes in a design in which they are particularly well adapted to cooperate with the thread guide 11 in the process according to the invention.
  • Each of the tube end portions and 21 shown in FIG. 3 has a peripheral annular recess 17 or 18, which is V- shaped in cross-section. In their operating position, the two tubes fitted on the arbor 3 are disposed so that their abutting end portions 20 and 21, specifically the recesses 17 and 18, are disposed directly under the slot 12 of the thread guide 11.
  • the yarns 1 and 2 which have been pulled through the slot 12 can easily be moved so that one yarn is engaged in the recess 17 and the other in the recess 18.
  • the yarns are initially wound up in the recesses 17 or 18 during the short time in which the yarns have been put on and the thread guide 11 has not yet been withdrawn.
  • the pull-off mechanism has been started by the operator to pull off the thread guide 11.
  • the yarns 1 and 2 leave the slot 12 of the thread guide and move out through the outlet 13 so that the yarns are disengaged while the yarn reserve continues to be wound up on each tube end portion.
  • the latter are quickly pulled away from the tube end portions and toward the respective package-winding zones.
  • the yarns are protected from the action of pressure. Without such recesses, the yarns would be pressed by the drive roller 8 which engages the tubes. Such pressure will be detrimental particularly if a relatively large length of yarn is wound up on one and the same portion of the tube and the yarn can not move along the tube as it is wound up. It is apparent that the recesses on the tube end portions serve to facilitate the operation in which the yarns are put on the respective tubes in order to improve the quick engagement of the yarns bythe tubes, and to protect the yarns from the pressure of the driving roller as the yarns are put on.
  • FIG. 4 shows two tube end portions 22 and 23 such as are intended for the tube 4 and 5 of FIG. I.
  • the recesses 15 and 16 are formed by a step-shaped reduction of the outside cross-section.
  • Each of the recesses 15 and 16 has a height or depth of about 5 millimeters; the recess 17 and 18 of FIG. 3 have similar dimensions.
  • Tubes having steplike recesses 15 and 16 are intended to avoid a pressing of the yarn which are been wound in the recesses.
  • each of the two tube end portions 24 and 25 has a bevelled surface 26 or 27.
  • These bevelled surfaces are arranged with mirror symmetry and adjacent to the butt joint of the tubes form a common V-shaped annular recess, which has the same function as the steplike recesses 15 and 16 of FIG. 4.
  • the bevelled surfaces of the tube end portions 24 and 25 may alternatively extend so that the tubes contact each other only with a very thin annular edge.
  • Winding apparatus for simultaneously winding-up two yarns at a velocity in excess of 1000 meters per minute comprising bobbin-winding means adapted to receive two detachably mounted winding cores in endto-end relationship along a common axis, each core having a winding zone axially spaced from the confronting ends of said cores the confronting ends of the cores including means for engaging and initially winding the yarns thereon, fixed guide means for each of said yarns positioned between the planes defining the axial confines of the winding zones, means to reciprocate the yarns in their respective winding zones and movable yarn guide means substantially in radial alignment with the confronting ends of the cores for simultaneously engaging and disengaging said two yarns adjacent the confronting ends of said cores.
  • peripheral recesses are a step, notch, or recess.
  • Apparatus of claim 3 wherein the movable yarn 8.
  • Apparatus of claim 6 which includes electromagguide means comprises a transverse slot for retaining the yarns, said slot diverging towards an outlet.
  • Apparatus of claim 6 which includes pneumatic means for transversely moving said yarn guide means. 5
  • netic means for transversely moving said yarn guide means.
