Definitions

  • This invention relates to an apparatus for treatment of yarn and more particularly to an apparatus for intertwining, interlacing, knotting, tangling, bulking or otherwise agitating or treating loosely associated, substantially untwisted man-made and synthetic multifilament yarns by action of a gas passing across or through said yarns and in the form of a high velocity jet stream.
  • the advantage of joining yarn ends by tangling or interlacing primarily resides in avoiding the necessity of gluing the ends or tying them together in oversize knots. Joining the ends is accomplished by arranging two filament bundle ends parallel to each other in an overlapping manner, and, while either holding or clamping the overlapped portions within the apparatus, a jet of fluid is directed across the overlapped portions.
  • the jet of high velocity fluid results in tangling th filaments and thereby causes the ends to be in effect fluid spliced. Friction between the thus tangled filaments results in a joint having substantially the tensile strength of unbroken yarn or filaments per se.
  • U.S. patent application Ser. No. 513,973, filed Dec. 15, 1965, now U.S. Patent No. 3,363,- 294 also commonly assigned herewith, provides means for automatically enclosing a bulking or tangling chamber which is connected to an enclosed muffler.
  • a muflier or some type of sound reducing structure is a prime requisite for lowering, and if possible preventing, extremely high noise levels. Fluids used in such operations issue from the jets at high speeds and cause an extremely high pitched nose. This noise at least is an extreme nuisance and in many cases is also harmful to technicians working around or operating the apparatus, particularly if a number of apparatus are operating at one time and in the same location.
  • the blowing chamber wherein the yarn bulking or tangling takes place is essentially defined by a reciprocable plungor carrying a jet tangling assembly,-a yarn receiving slot, and the plunger is enclosed by a cylindrical housing also having a cooperating yarn-receiving slot.
  • FIGURE 1 represents the apparatus according to the invention in a longitudinal cutaway section
  • FIGURE 2 is a cross-sectional view along line IIII in FIGURE 1;
  • FIGURE 3 shows the apparatus of FIGURES l and 2 in plan view
  • FIGURE 4 shows the detail of a slightly different embodiment of a segment of the apparatus shown in FIG- URE l;
  • FIGURE 5 shows a detailed longitudinal cutaway view of an additional embodiment.
  • numeral 1 refers to the cylindrical housing containing the bulking or tangling jet apparatus and defining the blowing zone.
  • the housing is secured by collar 2 fastened to flat supporting member 3 by bolt 4.
  • Reciprocable plunger 5 is guided by the inside of housing cylinder 1.
  • the plunger 5 is prevented from rotating by pin 6 attached to the cylindrical housing and fits loosely in guide slot 7 of the plunger.
  • Composing part of reciprocating plunger 5 is an annular support member 8 which serves to properly support and position jet 9.
  • a segment of jet 9 is also adapted to slide back and forth in a circular channel-like opening 10 of support 3 which directly communicates to a fluid feed conduit 11.
  • a fluid feed conduit 11 There is also provided in support 3 an annular groove 12 adapted to contain sealing ring 13. Sealing ring 13 prevents excessive escape of gases around the jet device.
  • Jet 9 has a channel 14 which terminates in a diverging fluid exit orifice 15. Tap or set screw 16 keeps the jet appropriately positioned in ring or annular member 8.
  • a cylindrical bushing 17 provided with an opening 18 which is clamped in the narrow end of a cylindrical plug or threaded bolt 19.
  • Bolt 19 is positioned in the narrow part 20 of reciprocable plunger 5.
  • Slot 21 provides for adjustment of the bolt assembly and, accordingly, resonance chamber 22. Any suitable means, for example, set screw 23 can serve to fixedly maintain bolt member 19 when it is properly positioned in an axial direction relative to the Plunger carrying the jet.
  • cap member 24 Internally threaded cap member 24 is attached to externally threaded part 20 of plunger 5. Collar 26 of cap 24, when plunger 5 is in the position shown in the drawing, is in contact with shoulder or abutment 27. Abutment 27 is formed by a rim 28 and composes part of the cylindrical housing 1.
  • blowing chamber 29 is bordered by a threadreceiving slot 30 which extends along half of the circumference of plunger 5.
  • This slot ends in two diametrically opposed openings 31 and 32 provided in recesses 33 and 34, respectively, serving as thread guides.
  • lips 35 and 36 are provided in recesses 33 and 34 which may be adjusted with the aid of set screws 37 and 38.
  • clamping discs 39 and 40 are provided with narrow slots 41 and 42. To prevent damage of the yarn being treated, it is preferred that the walls of the slots be well rounded and smooth.
  • Cylindrical housing 1 has a yarn receiving slot 43 which extends on half of its circumference and corre- 4 sponds to circumferential extending slot 30 and the reciprocating plunger. It is preferred that intheuzylindrical housing there be located two diametrically opposed discs 44 and 45 which are identical to discs 39 and 40 in plunger 5.
  • Threadreceiving slots 30 and 43 are positioned on the same side of the vertical center line 46 as shown in FIGURE Fluid removal channels 47 and 48 are provided in annular support 8 and blowing chamber 29 is in direct communication with the noise muffiing space 49 therethrough. Although only two fiuid removal channels are shown, others can be machined in the support, if desired.
  • the muflling space is defined by annular support 8, support 3 and cylindrical housing 1 and is partially bound by the outer surface of circular jet 9.
  • Channel 50 and support 3 interconnect the space with fluid discharge channel 51 indicated in FIGURE 1 by the broken lines.
  • fluid discharge channel 51 may be connected to a suction line through which the fluid from the assembly is removed.
  • the plunger When the plunger is in the position shown in FIGURE 1, it is to be assumed that it is in an operating position. That is, the apparatus is completely closed from the outside with the exception of a small space around the edges of the yarn supporting openings 31 and 32.
  • plunger 5 When a supply of fiuid operating the plunger is cut off, plunger 5 recedes and the rear side wall or abutment 52 of annular support 8 contacts wall 53 of cylindrical housing 1, thereby stopping rearward movement thereof and yet leaving sufiicient space between nozzle 9 in channel 11 to allow some fluid passage.
  • the thread-receiving slots 30 and 43 in the plunger and a housing align to form one thread-receiving slot.
  • the yarn to be tangled then may be brought into the blowing chamber 29 and is positioned in slots 41 and 42 of discs 39 and 40, respectively. Alignment of the yarn-receiving slots for positioning the yarn is obtained only when the apparatus is in this open position and the supply of operating entangling fluid is in some manner shut off.
  • the fluid drives the plunger forward and forward travel is stopped when cap 24 abuts wall 27.
  • Discs 39 and 40 being part of the plunger, carry the yarn. This position is referred to as the operating position and the two yarn-receiving slots in the plunger and the cylindrical housing overlap only to the extent that they form two eyelets which completely surround the yarn and serve as yarn guides.
  • the centers of the eyelets define a path for filaments and correctly position the yarn directly in front of the jet orifice 15. Adjustment of the discs (and accordingly the eyelets formed thereby) carried by the plunger relative to discs 44 and 45 secured in the housing may be made by turning cap 24.
  • the fluid causing reciprocation of the plunger into the operating" position also serves to tangle the yarn. It passes through jet device 9 into blowing chamber '29 and through the filaments, thereafter entering resonance chamber 22 through opening 18. The air becomes highly turbulent in the chamber and as a result an optimum intertwining effect is obtained and the filaments are thoroughly interlaced.
  • the yarn may be removed by merely depressing cap 24. Depressing the cap pushes plunger 5 to the rear wherein the extension of jet assembly 9 cuts off the major portion of the fluid supply. When the yarn is reinserted, the cap is then released whereupon the plunger will again be driven forward by fluid pressure acting thereon and it will again assume the operating position wherein tangling takes place.
  • the air supply to the blowing (or, if preferred, the bulking or tangliug) chamber may be cut off completely upon a continual depression of cap 24 by modifying the structure somewhat in support 3 and/or the rear portion of the jet.
  • a threaded insert is provided in support 3 having a circular groove 55 in communication with a slot or channel 58. Therefore when the cap is depressed, for example, by hand manipulation, the rear portion of jet 9 will completely abut the insert and close channel 11 as well as channel 58.
  • Adjustment of threaded insert 54 to insure proper seating of the jet can be made by turning key 59.
  • FIGURE 5 also shows a diflFerent embodiment wherein the blowing chamber 29 and jet 9 is fixedly maintained and surrounded by a movable cylindrical housing 1.
  • housing 1 will slide back and forth when under the influence of air pressure along a fixed cylindrical member now labeled bushing 5.
  • the yarn-receiving slots are the same construction as shown in FIGURE 1.
  • cylindrical bushing 5 defines an annular muflier chamber 49 enclosed on one side by annular support 3 which is essentially of the same construction as shown in FIGURE 1.
  • Annular support 8 positions the now stationary jet device 9. Wall thereof supports resonance chamber 22 attached to threaded plug 19'. Movement of cylindrical housing 1 in a rearward direction is limited by support 3 and in a forward direction by the head of bolt 62 threadedly attached to support 3 Fluid channel 63 allows a flow of pressurized fluid through the bushing to operating space 65. Consequently, during operation and when a fluid, such as gas, enters the apparatus fluid pressure will be asserted against the sidewalls in the space and will maintain the structure in the position as shown in the figure.
  • pin 66 Attached to collar 2 is pin 66 which slides in bore 67 of support 3. When cap 24 is depressed, the fluid flow is essentially shut off by pins 66. When the cap is released, however, enough fluid will pass through channel 63 to cause forward movement of the housing.
  • the present apparatus not only has the above-described advantage of reducing noise levels, but has an additional advantage attendant with compact construction which facilitates handling and point-to-point movement with ease. Moreover, it can be used to splice yarn ends or to continuously tangle a running length of yarn. In tangliug continuous lengths of yarn, it has been found that a more orderly entanglement and less bulking occurs. This contributes to maintaining 6 the initial yarn denier after passage through the apparatus.
  • a self-closing apparatus for intertwining, bulking, tangliug, interlacing or otherwise agitating a plurality of artificial filaments comprising:
  • (j) means attached to said housing for cutting off a major amount of said fluid being supplied to the apparatus when said housing is moved in the second direction along said cylindrical member.
  • said means further having an open and closed position wherein yarn is inserted and respectively treated by a fluid flow
