  • Two of the arcuate in- Rderemes cued serting members lay loops of weft in a split shed which is used for producing body tape and the third arcuate inserter is used UNITED STATES PATENTS for laying weft in a shed created for the production of pockets 3,529,634 9/1970 Griffiths et al ..139/22 n the body tape.
  • the two wefts laid in the body are brought 3,411,549 11/1968 Muller ....139/l24A together at an edge remote from insertion for the knitting 1,697,155 1/1929 Zulueta ....139/124 A therethrough of a catch thread to form a knitting selvedge, 2,469,202 5/1949 Murdock et al].
  • curtain heading tape it is known to introduce a monofilament weft to give lateral stiffness and pleating control.
  • An example of a curtain heading tape is the subject of our prior British Pat. No. 919 378.
  • One of the problems with a curtain heading tape including a monofilament weft is the lateral instability of the weave due to the slippery" nature of the monofilament weft whereby any lateral stress applied to the surface of the tape can easily cause the warp yarns to be parted to expose a grid of the monofilament weft picks.
  • Such problems can be reduced by packing the warp yarns closer together but this has other disadvantages such as stiffening the tape longitudinally and increasing the weight and cost of the tape.
  • a loom having weft insertion means in the form of pivotally mounted arcuate members adapted to enter and leave a weft shed to lay loops of weft therein and selvedge knitting means reciprocable alongside the warp shed characterized in that there are provided three such weft inserters two of which are adapted to lay loops of weft in a split shed used for producing a body tape and the third for laying weft in a shed created for the production of pockets on said body tape, the two wefts laid in the body being brought together at the edge remote from insertion for the knitting therethrough of a catch thread to form a knitted selvedge while the pocket weft loops are themselves knitted together to form interdigitated loops with or without a catch thread.
  • At least one of the weft threads inserted for the body tape is deflected in a vertical plane in the selvedge region of the warp to ensure the laying of the two loops in close proximity whereby a selvedge knitting catch thread may be looped around the warp threads simultaneously thus to bind both sets of weft loops together.
  • one of the body weft yarns is a relatively stiff yarn composed of, or including, synthetic plastics material.
  • FIG. 1 is a cross section through the weft of a fabric showing one repeat of pattern
  • FIGS. 2 to 5 show diagrammatically the various steps of shedding these warp yarns which produce a body part of the fabric
  • FIG. 6 is a detail view of part of a mechanism used in a loom to insert weft threads into a warp shed;
  • FIG. 7 is an underneath view of the mechanism of FIG. 6;
  • FIG. 8 is a perspective front view of a fabric produced by the carrying out of the invention.
  • FIG. 9 is a view similar to FIG. 1 of an alternative form of weaving, in this case only part of one pattern repeat is shown.
  • a curtain heading tape made in accordance with this invention and illustrated in FIG. 8 consists of a body part B on one side of which is superimposed a narrower tape C bound to the body part B by warps of the narrower tape being shed with the body warps, to form, by such periodic binding of the warp of the narrower tape C to the body B, a series of pockets into some of which may be inserted curtain hooks or rings.
  • the tape also has pleating cords P which are symmetrically arranged so that, when drawn, they both induce the same pleating formation in the body B of the tape.
  • the pleat formation shown in FIG. 8 is not of course the only one which can be produced. Variation of such pleat formation is possible by alteration of the position of the pleating cords and pleating hooks.
  • the tape is woven, as can best be seen from FIGS. 1 to 5, using two spun wefts and a monofilament weft.
  • one of the spun wefts 10 is used only in conjunction with the warp yarns l1 and 12 of the narrower tape C and the other spun weft 13 is used with the monofilament weft 14 to weave the body B of the tape.
  • the warp yarns 15, 16, I7 and 18 for the body B and the warp yarns l1 and 12 of the narrower tape C and the pleating cords P are shed using a loom equipped with seven shafts.
  • This loom is of the kind in which weft is inserted by means of a sickle and thus each insertion and retraction of the sickle will form a loop of yarn in the shed hence each pick is shown by two dots on the drawing.
  • the shafts for the warp yarns and the pleating cords are arranged as follows:
  • the two sickles 19, 20 used are moved simultaneously and in order to trap the relatively stiff weft 14 (particularly if it is a monofilament weft having a slippery surface) a split shed is used as can be seen from FIGS. 2 to 5.
  • the spun weft I3 is inserted into the upper part of the split shed and the other weft 14 into the lower part.
  • the shed changes are such as to ensure that the warp yarns l5, 16, 17 and 18 of each part of the split shed are interchanged and in order to achieve this in one practical manner shafts 4 to 7 may be shed as follows assuming that a cycle of shedding that commences with shaft 5 in an upper shed position.
  • the relatively stiff weft 14 is inserted in the lower shed so formed and the spun yarn 13 is inserted into the upper shed.
  • the first shed change after insertion of the weft causes the shafts to become positioned such that shafts 6 and 7 remain in the lower shed position and shafts 4 and are reversed so as to be located respectively in the upper and middle shed position.
  • Weft loops of yarns l3 and 14 are now inserted in the two parts of the shed.
  • the next shed change causes the shafts to become positioned such that shafts 4 and 5 are in the lower shed position shaft 7 is in the middle position and shaft 6 is in the upper shed position.
  • Weft loops 13 and 14 are again inserted in the two parts of the shed.
  • loops of weft are inserted by each of the two sickles 19, 20. Contrary to normal, practice, and in the interests of producing a non bulky selvedge, these loops are not looped one through the other but are laid close together one above the other by causing the weft 13 of the upper sickle to be deflected downwardly after it has passed through the shed.
  • the wefts l3 and 14, at the instant of time at which the sickles 19 and 20 are fully inserted in their respective sheds are thus located in close proximity and at this time a catchthread 22 (see FIGS.
  • FIGS. 6 and 7 illustrate the sickle arrangement used to carry out the operating cycle described above.
  • the sickles l9 and 20 are mounted on a common control arm 24 together with a sickle 25 which is used to insert weft into the shed of warp yarns l1 and 12 of narrow tape C.
  • the control arm 24 is mounted upon a carrier plate 26 formed at its end remote from the arm 24 with a toothed segment 27 through which passes the pivot 21 about which the sickles move in their arcuate path.
  • a cam element 28 carried by the pivot 21 and this is arranged to move in synchronism with the segment 27 for a purpose to be ex plained below.
  • Movement of the segment 27 and thus the sickles and cam element is controlled from the loom main drive via a linkage system (not shown) and a first reciprocable shaft 29 upon which is mounted a gear segment 30 meshing with the segment 27.
  • the cam element 28 has in abutment therewith a follower 31 mounted on a shaft32 carried in brackets 33 formed on the underside of a carrier plate 34 mounted on the loom frame (not shown).
  • the shaft 32 is spring loaded (by spring 35) to ensure that the follower 31 remains in contact with the cam 28.
  • a catch thread guide 36 mounted on the free end of the shaft 32 is a catch thread guide 36 which is adapted, by virtue of the movement imparted to it by the shaft 32, to reciprocate in a vertical arc in such manner as to cause, in use, the catch thread 22 to be laid in the hook of latch needle 23.
  • the latch needle 23 is mounted in a slide element 37 which also carries a second latch needle 23a reciprocable in a horizontal plane in a fore and aft direction relative to the loom healds.
  • a second shaft 38 driven from the loom main drive and this shaft has mounted thereon one link 39 of a parallel link arrangement.
  • the other end of the link 39 is pivotally secured to the slide element 37.
  • a second link 40 of the system is pivotally mounted on a bracket 41 of the carrier plate 34 and on the slide element 37.
  • a plate 42 mounted above the slide element 37 is a plate 42 in which are mounted two weft deflectors 43 and 44.
  • the deflector 44 is arranged to deflect the weft 14 of sickle 20 downwardly into close proximity with the weft 13 of sickle 19 when the sickles approach the extent of their travel through the shed so that the catch thread 22 laid in the hook of needle 23 can be looped by the two wefts 13 and 14 as described above.
  • the other deflector 43 serves, as will be explained below, to deflect the weft 10 of the narrow tape C onto the latch needle 23a to enable loops of this weft to be knitted one through the other as is usual in the formation of a selvedge in a needle loom.
  • the pocket forming narrower tape C is also woven and this is achieved by shedding the shafts 2 and 3 alternately into the top shed position to produce a separate shed (when the pockets are being woven).
  • the third sickle 25 inserts loops of spun yarn weft 10 into the shed formed by the warps 11 and 12 of shafts 2 and 3 and the loops of weft so formed are passed one through the other to form a knitted selvedge by the latch needle 230 which reciprocates alongside the warp shed.
  • the latch needle 23a collects the loops of weft in its hook and loops one through the other in known manner.
  • the warp yarns 11 and 12 fonning this tape are shed with body warp threads 15, 16, 17 and 18 to be woven with the spun yarn weft 13 of the body tape B.
  • the shafts 2 and 3 thus become shed with these shafts 4, 5, 6 and 7 which are at any instant in the cycle in the upper and middle shed positions so that the stiff weft 14 is woven throughout the tape always in the bottom part of the split shed of the body B.
  • Shaft l is shed to cause draw cords P to be inserted into the body tape B at the requisite intervals.
  • the tape so produced is capable of being woven relatively rapidly and it has the property of being relatively stiff in the weftwise direction.
  • FIG. 9 upon which reference numerals identical to those of FIG. I have been used it will be seen that it is possible to weave the body fabric B in a manner different to that disclosed above.
  • shaft 5 moves from an upper shed position to a middle shed position and then to a lower shed position and back to a middleshed position while shaft 4 moves from a middle shed position to an upper shed position and then back to a middle shed position and from there to a lower shed position.
  • shaft 6 moves from a middle shed position to a lower shed position, then back to a middle shed position and then an upper shed position while shaft 7 moves from a lower shed position to a middle shed position, then an upper shed position and back to a middle shed position.
  • This shed change cycle repeats continuously as the fabric B is being woven.
  • the stifl' weft 14 is woven at every double pick into the fabric as opposed to ever alternate double pick.
  • a loom comprising a split warp shed
  • two of said weft inserters being adapted to lay loops of body weft yarns in the split warp shed to produce a body tape
  • slide means mounted for reciprocal movement along side said warp shed
  • said slide means including first means for bringing together the two weft loops laid in the body tape at the edge remote from the weft inserters and second means on said slide means for inserting a catch thread through said two weft loops to form a knitted selvedge along one edge, said third weft inserter being used for laying weft in a warp shed to produce pockets on said body tape, and third means on said slide means for knitting the said pocket weft to form interdigitated loops.
  • said second means includes two needles, one of said needles being adapted to receive a catch thread from a thread guide and the other of said needles being adapted to knit loops thereof, one through the other to bind directly loops of weft laid in the shed of said body tape.
  • one of said body weft yarns comprises a relatively stiff yam of synthetic plastic material.
