Definitions

  • the present invention generally relates to the field of curtains, and especially it concerns a guide tape for curtains, of curlable type, and the respective manufacturing method.
  • the automatic curling guide tapes can also have a supporting function and generally they are attached to the curtain at its upper edge. The attachment is obtained with seams, or gluing, with buttons, etc.
  • the tapes are mainly made of a synthetic material, such as polyethylene terephthalate (PET) for example, although in the past natural fibers, for example cotton, have been used.
  • PET polyethylene terephthalate
  • the automatic curling tape is provided with one or more strings sliding in appropriate guides obtained in the tape itself. By pulling the strings the user causes the tape and its associated curtain to curl.
  • the definitive arrangement of the curled, or pleated, curtain depends on the tape arrangement, that is on the geometrical proportions and the pitch of the guides wherein the strings slide.
  • the English Patent Application GB 2298357 describes an automatic curling guide tape provided with two strings.
  • the strings extend parallel in the longitudinal direction, that is in the development direction of the tape and they are slidingly accommodated in a plurality of longitudinal guides obtained in the tape itself.
  • the distance between two consecutive longitudinal guides is about twice the length of each guide.
  • the European patent application EP-A-1498056 discloses an automatic curling guide tape allowing to obtain a substantially sinusoidal spatial progress of the respective curtain, supported by a horizontal pole.
  • the guides in which the strings slide are not directly obtained in the tape, but they are obtained in two additional parallel bands sewed onto the tape.
  • Such bands can be curled at an intermediate portion between two points of attachment to the tape; on the contrary at the attachment points the guides are obtained in which the strings, that can be pulled by user, can slide.
  • the curled curtain arrangement is shown in figure 2 .
  • the sinusoidal progress can be obtained due to the fact that only one intermediate portion of the additional bands can be curled.
  • the current automatic curling guide tapes allowing to obtain a substantially sinusoidal progress of the curtain are complicated to manufacture.
  • the positioning of the additional bands on the tape must be as accurate as possible in order to prevent unevenness in the curling of the curtain.
  • the seams provided for the attachment of the additional bands to the tape must be accurate and resist to washings.
  • the invention in its first aspect, therefore relates to a guide tape for curtains according to claim 1.
  • the invention relates to a guide tape for curtains, comprising a backing fabric attachable to a curtain and deformable between a substantially flat arrangement and a substantially sinusoidal arrangement, and at least one string, operable by the user to deform the backing fabric.
  • the backing fabric comprises in its turn a plurality of main guide channels, aligned along a same longitudinal direction and spaced each other according to a predefined pitch, and corresponding intermediate guide channels, longitudinal too, between two main consecutive guide channels.
  • the string is slidingly accommodated in the main guide channels and the intermediate guide channels.
  • each of the intermediate guide channels is obtained in a portion at least partly curlable of the backing fabric bounded by two through buttonholes, that is two windows obtained in the backing fabric.
  • the through buttonholes are parallel to each other and parallel to the corresponding intermediate guide channel.
  • the guide tape does not provide sewed portions on the backing fabric.
  • the intermediate guide channels are obtained at a portion of the backing fabric itself.
  • the tape according to the present invention does not provide portions arranged or sewed on the backing tape; in other terms the curlable portions of the tape are made in a single piece with the backing fabric, that is they are part of the fabric.
  • main and intermediate guide channels are consecutively arranged in longitudinal direction to form at least one series.
  • the backing fabric can comprise a second, a third, etc., series of main and intermediate guide channels, parallel to the corresponding main and intermediate guide channels of other series.
  • the pitch between the main guide channels is constant.
  • the guide tape comprises two or more parallel strings and it comprises, for each string, corresponding main guide channels and intermediate guide channels.
  • the strings are two and they extend along the backing fabric parallel one to each other.
  • the application of a suitable tension on strings, by the user, causes the curling of some portions of the backing fabric; the backing fabric is deformed by changing from a substantially flat arrangement to a substantially sinusoidal, or curled, or pleated arrangement. The deformation is clearly reversible when the tension on the strings ceases.
  • the through buttonholes of each couple of through buttonholes extend from opposite sides with respect to the at least one string.
  • the extension of the buttonholes in longitudinal direction is preferably equivalent to the extension of the corresponding intermediate guide channels.
  • the through buttonholes preferably extend parallel to the strings and from opposite sides with respect to these.
  • the through buttonholes for example, extend parallel to the strings and from opposite sides with respect to these.
  • the through buttonholes preferably are three and two strings extend between two parallel adjacent through buttonholes.
  • the through buttonholes preferably do not extend at the main guide channels; in other terms the fabric is not crossed by the above through buttonholes at the main guide channels.
  • the portion of the backing fabric, in which the intermediate guide channels are obtained is curlable at a length equidistant from the corresponding main guide channels.
  • the curling is obtained, for example, by folding the backing fabric portion in edges overlapped one to each other.
  • the curling of the curlable portion of the backing fabric is obtained by combining each string with the backing fabric such that the string bypasses the corresponding intermediate guide channel and crosses a plurality of said overlapped edges.
  • the main guide channels and the intermediate guide channels are woven as tubular in the backing fabric, by using a corresponding warp thread.
  • the curlable portion of the fabric itself does not adopt the substantially sinusoidal progress of the remaining portion of the backing fabric.
  • the curled portion keeps a determined stiffness preventing it from following the deformation adopted by other portions of the backing fabric.
  • the main guide channels each have a length between 2 cm and 5 cm; the pitch between the main guide channels is comprised in the range of 2 ⁇ 4 times the length of the main guide channels.
  • the main guide channels each have a length of about 3 cm
  • the intermediate guide channels each have a length of about 19 cm and such a length corresponds to the pitch between two main consecutive guide channels.
  • the invention in its second aspect relates to a method, according to claim 10, for realizing a guide tape for curtains.
  • the invention relates to a method for realizing a guide tape for curtains, of the type comprising a substantially flat backing fabric deformable according to a substantially sinusoidal arrangement and comprising at least one string operable by the user to deform the backing fabric, the method comprising the steps of:
  • the method does not provide a step of seaming on the backing fabric a binding containing the intermediate guide channels; on the contrary the method according to the present invention provides the intermediate guide channels to be directly obtained in the backing fabric, preferably during the weaving step.
  • the method comprises the further steps of:
  • a weft and three warps (three warp threads) a first warp defining the portion of the backing fabric intermediate between each couple of through buttonholes, a second warp defining the portion of the backing fabric on the left of each couple of through buttonholes and a third warp defining the portion of the backing fabric on the right of each couple of through buttonholes and the portions of the backing fabric comprising the main guide channels.
  • the backing fabric of the tape is realized by a loom and the through buttonholes are obtained using three distinct warp threads on the same weft.
  • the through buttonholes are obtained die cutting the backing fabric.
  • the through buttonholes are obtained passing the backing fabric through a die cutting roll and a counter-die cutting roll.
  • the guide tape according to the present invention is simple in its structure while being strong.
  • the tape is preferably made with PET, and it is therefore light and washing - resistant.
  • the tape structure allows its continuously realization directly by the loom, with evident advantages relating to the productivity and cost effectiveness.
  • a guide tape 1 is shown according to the present invention comprising a backing fabric 2, attachable to a curtain, and a string 3 intended to be pulled by the user to deform the backing fabric 2, and therefore its associated curtain, from the flat arrangement shown in figure 1 to the substantially sinusoidal arrangement shown in figure 3 .
  • the backing fabric is preferably, but not necessarily, made of polyethylene terephthalate (PET) with one weft and more warp threads, as it will be described in detail in connection with the method according to the present invention.
  • the string 3 also is preferably made of in polyethylene terephthalate (PET) with an appropriate warp thread.
  • the tape 1 is substantially composed of a modular portion 11 repeated many times in succession, that is the tape 1 comprises a plurality of side by side modular portions 11. In the attached drawings only two consecutive portions 11 are shown for simplicity; the tape can clearly be composed of more consecutive portions 11.
  • Each modular portion 11 comprises a length of the backing fabric 2, that is a strip of the backing fabric 2 extending along a longitudinal direction, and, in the embodiment shown in figures 1 and 3 , a string 3.
  • the string 3 also extends in longitudinal direction, that is parallel to the development direction of the strip of backing fabric.
  • the backing fabric 2 has two discontinuities 4 consisting of through openings through the backing fabric 2 itself, defined as buttonholes.
  • the buttonholes 4 have an elongate shape and they develop along the longitudinal direction parallel to the string 3.
  • each modular portion 11 of the backing fabric 2 the buttonholes 4 are arranged in parallel couples, such as two rails, and they extend for a length smaller than the length of the modular portion 11; therefore at the virtual connection between two consecutive modular portions 11 the backing fabric 2 does not have buttonholes 4, that is it is continuous for its full length.
  • the portion of the backing fabric 2 included between the two buttonholes 4 is referred with the reference number 2'.
  • the guide channels 21 are shaped as tubular pockets of the backing fabric 2 and they are preferably obtained during the weaving step with an appropriate warp thread.
  • the intermediate guide channels 22 represent the natural extension of the main guide channels 21, but differently from the main guide channels 21 extending at the portion of the backing fabric not comprised between the buttonholes 4, the intermediate guide channels 22 extend only between two parallel buttonholes 4 at the portion 2'.
  • the intermediate guide channels 22 are shaped as tubular pockets of the backing fabric 2 and they are preferably obtained during the weaving step with an appropriate warp thread.
  • the guide channels 21 and 22 alternate in succession along the development of the string 3.
  • the portion 2' of the backing fabric 2 is at least partly curlable at its half. Referring particularly to figure 1 , the folding lines 5 of such a portion 2' are shown.
  • the string 3 passes alternatively over and under the portion 2' of the backing fabric 2 and the folding lines 5 are intermediate between the crossing points.
  • the structure of the tape 1 allows the user to easily obtain the sinusoidal progress of the curtain combined with the backing fabric 2.
  • Figure 3 shows the tape 1 in a deformed arrangement of the backing fabric 2.
  • the string 3 has been pulled by the user; thereby the portions 2' have been curled (or folded, or pleated), and this causes a partial stiffening of the portions 2' themselves.
  • the remaining side of the backing fabric 2 is forced to adopt the sinusoidal progress shown in figure 3 .
  • Figure 2 shows an alternative embodiment of the tape 1 comprising two parallel strings 3, accommodated in corresponding main guide channels 21 and corresponding intermediate guide channels 22 developing between the buttonholes 4.
  • the strings 3 can be more than two, for example three, four, five, etc.
  • the buttonholes 4 are three.
  • buttonsholes 4 are obtained during the weaving step of the backing fabric 2, but alternatively they can be die cut.
  • the main guide channels 21 have a length of about 3 cm
  • the intermediate guide channels 22 have a length of about 19 cm corresponding to the pitch (always constant) between two consecutive main guide channels 21.
  • intermediate guide channels 22 can be shorter that the pitch between the main guide channels 21.
  • Figure 4 shows a principle scheme relating to the weaving of the backing fabric 2; the scheme helps to understand how the buttonholes 4 are formed.
  • the backing fabric 2 is realized with a weft and a warp thread O1 guided by a closed yarn guide needle 7, termed closed sickle.
  • the length of the backing fabric 2 varies from a minimum (portion on the right of the right buttonhole 4) and a maximum (portion free of buttonholes 4).
  • the fabric portion on the left of the left buttonhole 4 is realized by braiding the weft with a second warp thread 02 and the intermediate portion 2' between the buttonholes 4 is obtained by braiding the weft with a third warp thread 03.
  • the warp threads 02 and 03 are guided by an open yarn guide needle 6, termed open sickle.
  • the open sickle 6 takes the wefts that are fitted within two heddles and goes on weaving with the warps 02 and 03.
  • the three warp threads O1-O3 are bounded with the outer weft of the closed sickle 7 starting from the warp thread 03 till the warp thread O1.
  • the yarn guide needles of corresponding warp threads are referred.
  • the strings 3 are obtained by feeding the corresponding warp threads (not shown in fig. 4 ).
