Description

  The present invention relates to a curtain top (heading) tape.

  The common curtain top tape used is fixed along the top region of the curtain and is used with a hanging hook, which is one or more longitudinal (for pleating tape) It has a woven structure that includes a longitudinal draw cord and a row of one or more longitudinal pockets that receive a hanging hook.

  British patent GB2238800B describes the production of this type of tape having a line of pockets defined by an elongate woven structure woven into the woven basic structure of the tape. The elongated woven structure has regularly spaced portions formed by freely 'float' threads on the surface of the basic structure defining the pocket.

  Curtain top tape is also secured along the top region of the curtain in use and is used with a curtain pole. One known tape of this kind has circular holes that are constrained by eyelets and spaced regularly. A matching hole is cut into the curtain fabric and an annular insert is pushed through the curtain and secured to the eye hole. The top of the curtain is then bundled so that the eye holes are lined up by interconnecting plastic ties attached to the eye holes. The curtain bar can then be inserted through the eye hole.

  However, the use of plastic straps attached to the eye holes makes it difficult to achieve a neat and smooth bunching and to catch on the adjoining material and the surface. As for the, the appearance of the finished curtain is damaged.

  The use of a typical draw string arrangement to achieve a bundle of eyepiece tapes as described above allows the string to be traversed across a tape that is long enough to form a relatively large loop containing two eyeholes. It is not suitable because it needs to be pulled, so it cannot easily form an open ring that is free when such a free floating string of such length is pulled, and is actually a closed ring Tend to draw the entire tape to form.

  One object of the present invention is to provide a curtain top tape of the type used with curtain rods that can be easily pulled to provide a well-organized and wide-opened ring with a tape structure that is convenient to manufacture. That is.

  Therefore, according to the present invention, a curtain top tape having a base fabric with holes spaced along it, by providing additional yarns forming at least one row of elongated pockets. Each pocket is secured to the substrate fabric at its opposite end and freely floats from the substrate fabric between the ends, spans at least two of the holes, and at least 1 A curtain top tape is provided in which two drawstrings extend through the thread in the pocket.

  With this arrangement, it is possible to bundle the tape by pulling the (or each) drawstring to pleat the thread in the pocket, so as to form a loop each containing at least two of the holes. The use of drawstrings (or laces) combined with pocket threads allows the tape to be made conveniently and also facilitates a controlled bundle that guarantees a clean end without the loops closing undesirably. Make the tape possible to do.

  In this way, the arrangement preferably has one or more portions in which the drawstring floats freely from each pocket in at least one initial region, preferably its central region and at least one further One or more portions interconnected with the pocket in the region, preferably having its end region, whereby the at least one first region pocket is pleated when the string is pulled. Made, but leave the pockets extending in the at least one further region. This can ensure that the tape is aligned and bundled while preventing the formed loop from being completely closed.

  Most preferably, the pockets are woven from warps and wefts as a narrow weave structure which may be a double plain weave.

  Also preferably, the (or each) drawstring is knitted with the woven pocket structure to move with the free-floating portions in alternating positions, at least in the (or each) first region, Each such free-floating portion extends across a plurality of wefts.

  Furthermore, the (or each) drawstring may be tightly knitted with a woven pocket structure weft in the further region, for example as a 1: 1 weave, so as to cause the connection between them. .

  Most preferably, the row of (or each) pocket is defined by a continuous longitudinal structure, the thread of which is between the pocket and the (or each) drawstring extending through the continuous longitudinal structure, Interconnected with the base fabric of the tape.

  The base fabric is, for example, a double plain weave fabric, preferably a woven fabric, and the connection between the pocket structure and the base fabric is preferably a thread of the pocket structure and a yarn of the base fabric. By weaving. In particular, the connection is preferably in a generally 'tube' manner, for example to facilitate the movement of the drawstring, so that the vertical central region of the pocket structure is substantially free from attachment to the substrate fabric. This is done by weaving the warp yarn of the edge of the pocket structure and the weft yarn of the base fabric.

  In order to ensure a good connection, the warps of the pocket structure may be knitted with a small number of the weft yarns of the base fabric, one at each end of each pocket and each of the structures between adjacent pockets. Leave one as the center of the part.

  In one embodiment of the present invention, for example, one adjacent to each end of the base fabric, and each such structure has one drawstring, each having a pocket of one structure. There are two continuous vertical pocket structures that line up across the pockets of other structures.

  Preferably, each pocket spans two holes, and a mark may be provided in the middle of each portion of the tape between the vertically adjacent pockets, when the mark is attached to the top of the curtain, This guides the cutting of the length of the tape to ensure a neat shape at the end of the tape. This landmark may be defined by one or more colored threads that are exposed on the surface of the tape only at preferred locations. Conveniently, two such yarns may each be present adjacent to the opposite ends of the substrate fabric.

  The hole in the base fabric is preferably a circular hole of a normal size, preferably cut out by a machine precisely at a desired position, in particular at a position which is previously related to the position of the pocket. In this way, there are hole sets, each set being symmetrical with respect to an individual pocket, and said sets being equally spaced from each other.

  The tape is attached to the top of the curtain fabric by stitching or otherwise. When attached, holes aligned with the tape holes can be cut out in the curtain fabric. In each set of holes aligned in a row, a perforation structure is secured to the curtain fabric and tape material, and the perimeter of such holes is fastened between the front and back elements of each perforation structure The assembly can be completed. In one embodiment, such elements are separate annular elements that close together with pawls or other adjustable connections to allow various divisions of the elements applied to various fabric thicknesses. The assembly according to claim 16.

  The invention will be further described by way of example only and the associated drawings.

  With respect to FIG. 1, this shows a curtain top tape having a narrow substrate fabric 1 continuously woven as 88 mm wide.

  The fabric 1 is woven from warp and weft which can be cotton, polypropylene, or any other suitable natural or synthetic material or combination of these materials. The yarn may be white multifilament, transparent or see-through monofilament, or any other suitable yarn.

  The fabric 1 is woven by a needle loom giving a plain weave fabric, looped (using a latch needle) around the warp at the edges of the opposite longitudinal ends 2, 3 of the fabric It has a weft thread inserted with two picks per mouth and a single warp.

  Reference is made to British Patent GB 2238800B for a suitable background fabric structure and further details of the equipment for making such a background fabric structure.

  In such a portion, which is approximately 8 mm from the end and closely adjacent to each end 2,3, there is an inlaid bundle of additional thick warp yarns 4. These yarns 4 are individually interlocked with the weft yarns of the base fabric 1 to produce cylindrical portions on the opposite sides of the fabric. These yarns 4 are all composed of white multi-fiber warp yarns 4a except for one such as the green warp yarn 4b. This thread 4b is generally placed in a bundle of threads 4 so that it is covered by another white thread 4 and is therefore not visible. An exception to this is that every 228 mm the green thread 4b 'misses' and floats on several wefts, so that at the part 4c on the surface 1a of the substrate fabric (as shown in Fig. 1), about 5mm clearly Appears.

  The green yarn 4b is exposed at regular intervals with regular intervals determined by repeated and repeated operations in the manufacture of the tape, and the exposed portion 4c along one end of the tape is exactly aligned with the exposed portion 4c at the opposite end of the tape. Lined up.

  These exposed portions 4c of the yarn 4b serve as landmarks in cutting across the tape as described further below.

  There are pocket structures 5 respectively attached to the bundles 4 of the inlaid threads, each being attached to the opposite side of such a bundle 4 with respect to the ends 2, 3.

  The pocket structure 5 includes, for example, continuously woven strips having a width of 8 mm, a weft thread that is inserted around the warp yarn at the opposite ends of the strip and inserted with two picks per hook, and a single woven fabric. Of warp.

  The pocket structure 5 overlaps the surface of the base fabric 1 but is completely separated from the base fabric 1 except for a short length 5a aligned with the green mark 4c.

  These attached lengths 5a, which are 48 mm in length, are placed in the center of the green mark 4c, and the edge of the base fabric 1 by the warps of the opposite edges of the pocket structure 5 and the wefts 6 of the three base fabrics. The warp yarn is knitted with the weft yarn of the base fabric so as to extend in parallel with 2, 3, and this weft yarn is knitted with the warp yarn of the pocket structure 5 at each end and center of the attached length 5a. It is.

  In a portion between the adjoining lengths 5a, there is a long 'pocket' 5b which is 180 mm long and floats freely from the base fabric 1. The pockets 5b of the strips 5 of each pocket structure are accurately spaced and of normal dimensions, and are aligned with the pockets 5b of the other strips 5 across the tape.

  There is a cord or string 7 knitted along the center of each pocket structure strip 5. The string 7 has a length 7a of about 10 mm, and has a portion 7a that floats on several wefts. This portion is located at the center of each fixed length 5a of the pocket-shaped strip 5 on the exposed front surface of the strip 5. And the center of two equal length parts (not shown) below the fixed length 5a.

  Inside the pocket length 5b, the drawstring 7 having a length of 35 mm is knitted 1: 1 with the weft in each end region 5c of the pocket length 5b, and then the drawstring is exposed to the pocket length 5b. In the central region 5d on the front surface and four identical portions (not shown) below the central region 5d, there are four raised portions 7b that overlap on several wefts and have a length of 10 mm.

  As will be described below, the drawstring 7 can be pulled at its end to bind the tape, and the form of attaching the fixed length 5a to the base fabric 1 facilitates the movement of the string7.

  The circular hole 8 having a diameter of 40 mm is accurately cut into the base fabric 1 using an appropriate cutting device. Such holes are in pairs and are arranged symmetrically with respect to the middle point of each pocket 5b, the sets of holes 8 are separated by 106 mm, for example, and the holes of each set are separated by 122 mm, for example. .

  In use, the tape described so far is sewn along the inner surface of the upper part of the curtain (not shown) with the surface 1a of the base fabric 1 exposed.

  The holes 8a are cut into the curtain fabric 9 by any suitable method and are aligned with the holes 8 in the base fabric 1.

  The eye hole 10 is applied to the curtain 9 and the base fabric 1 at the position of the hole.

  As shown in FIG. 3 and as described in the co-pending application of the same day, the eye 10 includes two ring structures 11, 12 that are tightly closed by a width adjustable ratchet mechanism 13. This ring structure is pushed through the hole 8 from the exposed front surface of the curtain material 9 and the exposed front surface of the base fabric 1 through the holes 8 to be connected to each other. And the flanges 15 and 16 having a structure overlapping with the exposed surface of the curtain material 9 and the base fabric 1.

  The tape is cut to a length suitable for the length of the upper part of the curtain at the position of the green mark 4c closest to the end of the upper part of the curtain. This ensures that the curtains are in place when they are bundled, i.e., eliminate the unsightly protruding end portions as described further below.

  The upper part of the curtain is bundled by binding the pull string 7 at one end of the tape and pulling the string at the other end.

  When the string 7 is pulled along the length of the pocket strip 5, a pleat is formed in the pocket length 5b as shown in FIG.

  These lengths 5a form effective 'tubes' with the base fabric 1, and since these lengths 5a produce little or no folds, the string 7 moves easily through the fixed length 5a. be able to.

  In the central region 5d where the four raised string portions 7b easily pull the pocket strips 5 together, the string 7 creases the pocket length 5b. Little or no creases occur in the region 5c between the central region 5d and the fixed length 5a, because the drawstring 7 is knitted into the pocket strip 5 in this region.

  The folds in the central region 5d can be clamped or folded so that the pocket length 5b is as short as 10-15 mm, for example.

  As a result, the holes 8 are substantially aligned with each other along the length of the top of the curtain to receive the curtain rods; and the curtain material and tape are bundled into a smooth open loop. The loop is held in place by a partially pleated pocket 5b, which ensures that the curtain top is in place. By cutting the tape with green marks 4c as described above, at each end, the top of the curtain forms a ring rather than the free end of the tape, thereby ending the curtain end in an aligned manner. Can be guaranteed.

  The described tape depends on the pocket structure that is woven to achieve a neat bundle, so that the tape can be conveniently manufactured using conventional techniques.

  Of course, the present invention is not limited to the details of the above-described embodiments, which are merely described as examples.

  In particular, the dimensions given are only examples. Different dimensions and different relative dimensions can also be used, depending in particular on the bunching effect or the required 'clearance'.

  The majority of each pocket length 5b (eg 1/2 to 3/4, especially about 2/3) is pleated so that the pleat length is small, but other arrangements are also possible. is there.

FIG. 2 is a plan view in an unfolded form of one embodiment of the curtain top tape according to the present invention prior to the cutting of holes therein; FIG. 2 is a perspective view of FIG. 1 showing a pleated state. It is sectional drawing of the eye hole used with a tape.
