Abstract

The present invention is directed to window treatments such as vertical blinds manufactured from a knitted textile material. Each of a plurality of louvers is knitted into a single panel and attached together by a frangible hinge which permits the louvers to pivot relative to each other, or may be torn to separate the louvers from each other without damage to the louvers. In installations requiring multiple panels to be attached together, a terminus may be provided to permit attachment of one panel directly to the other. Alternately, a connection strip may be employed between two panels. In the event that the knitted textile louvers are not sufficiently opaque, auxiliary louvers may be provided and attached in alignment over the louvers.

Description

The nothing of fabric wear and tear easily broken connection and the vertical blind system that comprises that this is connected

Technical field

The present invention relates to inweave during manufacture the easily broken connection of fabric side (fabric panel).More specifically, the present invention relates to have the vertical blind system of decorated dormer leaf, these decorated dormer leaves are made in single fabric side and by the easily broken hinge of braiding or tear edge strip (tear awayfringe) and be attached to together.

Background technology

When weaving big fabric side, usually have the fabric that will finish and cut into the situation of less sheet in the product of finishing, to use, for example be used for curtain.But cutting of fabric can bring many problems that occur during manufacture, is to need extra step to cut fabric exactly the most significantly.Equally, because its intrinsic characteristic, cut and interrupted cloth construction, stayed the wearing and tearing limit that to destroy fabric intensity in the product of finishing or outward appearance.

In many windows or door opening application, expectation control allows the light amount by window or door opening.For example, at the fine day of temperature climate, sunlight is for occupants's comfortableness strong excessively (overheated), and can damage inner furniture and it is faded or become frangible.Usually, the shutter of being made up of independently rotary a plurality of opaque material window bars is mounted to coordination mode and blocks all or part of light.When these window bars were horizontal, this assembly was commonly referred to " venetian blinds (venetian blind) ".

In big window or door, because in the time need not blocking sight line or clean the glass of back, be difficult to rise fully venetian blinds, so venetian blinds is unpractical.Therefore, the modification of a kind of being called " vertical blind " is installed usually, wherein rotatable window bar is hung vertically in the horizontal bar mechanism (traversemechanism) of the suspension bracket with a plurality of rotations of coordination respectively from its end.Vertical blind is most commonly used in the more common facility of big window, for example in the gate or picture window of commercial building or dwelling house.

Vertical blind is well-known, generally includes from the opaque material elongate strip or the window bar of the top horizontal bar mechanism vertical hanging that is provided with independent rotatable suspension bracket.The conventional window leaf of vertical blind (being also referred to as window bar or blade) is suitable for transverse movement between the position of the position of drawing back shutter and stretching, extension shutter, shutter is opened to the horizontal bar adjacent with its top or an end or the opposite end of passage in drawing back the position of shutter, and in stretching the position of shutter the window leaf usually along the identical distance of the length direction each interval of horizontal bar or passage.

Window leaf itself also is suitable for opening and closing selectivity rotation between the position around its longitudinal axis.When shutter stretched, the interval between the window leaf was substantially equal to its width.Therefore, when horizontal bar mechanism for example is positioned to when the window horizontal length is above this window, the light by window is blocked in the rotation of window leaf selectively.

The vertical window leaf can be made by the material that vinyl material or other are fit to, and it can dye and match with the mass-tone that increases characteristic to the room or be coloured to the room.Because these window leaves are separately to make, so they are limited to monochrome or simple vertical decorative pattern usually.Attempt continuous horizontal effect of decorative patterns in this way if make, then be very difficult to exactly horizontally continuous window leaf.Each window leaf in the horizontal decorative pattern is all represented independent decorative pattern fragment, and this fragment does not line up slightly will be not attractive in appearance significantly and can destroy the shutter aesthetic appearance.

The window leaf also can be made or be covered by textile material by textile material, to obtain specific design effect.The window leaf that is formed by fabric may lack the rigidity of entity window leaf fully, therefore can the suspension bracket reinforcement be set at the top and in the bottom suspending weight be set, and hangs equably to allow the window leaf.

Current, fabric louvered window leaf is rolled into by the continuous web that is cut into window leaf width from the broad fabric warrping.These volumes all cut into the length of appointment individually and make, to form the window leaf.This production method is because can't guarantee decorative pattern component level ground arranges, so be very difficult to comprise horizontal decorative pattern.Laterally cut the window leaf even equal the pattern fabric volume of window leaf length from width, processing in addition (hardware for example will be installed be attached to each window leaf) brings for each window leaf is enough to destroy the horizontal vertical error of decorative pattern.

The fabric window leaf of being made by single fabric warrping also has a shortcoming, is exactly that the window leaf is easily along its longitudinal edge wearing and tearing, especially because machine washing causes wearing and tearing.Must have existing continuous structure because cut the material of window leaf, certainly lead to the edge that structure is interrupted so it cuts, thereby cause a succession of loose silk thread.When unprocessed, these silk threads are loose often, thereby fabric is died down, thereby along with the past of time with owing to washing produces inaesthetic wearing and tearing limit.Prevent the manufacturing step that expends cost that this result need add.

Know that also wherein the opaque vertical window bar of shutter is cooperated with transparent fabric, so that provide scattering to the light that enters between the opaque window bar when shutter is stretched and be shown in an open position with vertical blind and transparent fabric combination.This provides pleasant aesthetically effect, and owing to reduced the definition of watching interior of building from the outside, and increased privacy.

People's such as Colson U.S. Patent No. 5,638,880 disclose a kind of like this combination vertical shutter, the opaque blade of rigidity that wherein has traditional vertical blind layout locates to be attached to a slice transparent fabric at one of its longitudinal edge, make that the light that passes between the louvered window bar passes transparent fabric when shutter is opened.Because blade is made by the material different with fabric, so transparent fabric must be attached on the blade through other increase step, therefore this shutter may be very expensive.In addition, although can or remove the width that the plurality of separate blade is adjusted traditional vertical blind by increase, but in the combination shutter, become single structure and can not adjust because blade comes down to link together by transparent fabric, thereby need these shutters according to concrete width customization, this has also increased its cost.

The U.S. Patent No. 3,851,669 of Shapiro discloses another example of combination shutter.The Shapiro patent be absorbed in be fit to supported and have a curtain of alternately opaque and transparent vertical component in the mode of vertical blind.Opaque section is generally rigidity, and can rotate selectively, passes transparent part or shuts out the light by transparent part is folded on the opaque section to allow the light transmission.Except the shortcoming of discussing at people's such as top Colson patent, another significant disadvantage is that rigid blade and fabric are overlapping, thereby needs extra fabric to block whole window.In addition, blade or window leaf only are attached on the textile material along the top margin and the base of textile material, have therefore retrained operating period of blocking window control to textile material.

Another embodiment of Shapiro patent disclosure is the shutter with alternately opaque and transparent part, has wherein removed the vertical extent window leaf of common rigidity, and is substituted by the fabric side with pore vertical component alternately and gross porosity vertical component.Pore part can be provided with reinforcing element at its edging place, top, and pore part is connected on the vertical blind horizontal bar, and pore part can be used as the window leaf and is rotated from horizontal bar.When being shown in an open position, gross porosity partly is arranged to allow maximum light to pass through.When in the closed position, pore part rotation makes its edge overlapping with adjacent pore part, with the transmission of prevention light.Although this embodiment has overcome some restrictions of a Shapiro embodiment, because pore " window leaf " part lacks rigidity, this shutter still has shortcoming.The resistance that all trials that the window leaf of the 2nd Shapiro embodiment is rotated are subjected to all can increase gradually along window leaf length, causes the inaesthetic non-homogeneous distortion that shutter can't be worked.

Therefore, need a kind of can be on its window leaf level show the vertical blind of decorative pattern, make decorative pattern arrange and significantly do not line up from a window leaf to next window leaf.

Also need a kind of vertical blind that has fully the window leaf that forms by fabric, described window leaf has independently braiding structure, wherein main linear slit does not interrupt basically and does not have loose the end of a thread, and wherein said window leaf can be machine-washed and can not be produced the wearing and tearing linear slit.

Also need a kind of vertical blind with a plurality of window leaves that formed by single fabric warrping, wherein this volume can cut into the fabric side of all lengths during installation as required.

Also need a kind of braiding shutter fabric side, it has open top and bottom size to allow regulating height and alignment during installation.

Also need to be attached to together to be used for the fabric side of the application wideer than the Breadth Maximum of single fabric side.

Also need a kind of combination shutter that comprises the fabric side that has made up transparent and shading light part, described shutter has as the high rigidity section of window leaf and allows the unified window leaf of adjusting with the structure of change by the light quantity of shutter transparent part, and need not hard window leaf fabric side.

Also need a kind of combination shutter, wherein shading light part is provided with the opaque auxiliary window leaf of rigidity (auxiliary louver) that increases the light quantity of being blocked by the window leaf in fastening position.

Also need a kind of fabric combination shutter that can produce with normal width, this width can easily be regulated between installation period as required carrying out on the non-standard window.

Summary of the invention

The present invention attempts to solve these problems and satisfy these demands from the easily broken connection of wearing and tearing of the nothing of a plurality of parts of single fabric side braiding vertical blind by designing a kind of permission.

According to one embodiment of present invention, provide a kind of vertical blind with a plurality of rectangular fabric window leaves, these window leaves are used for specific width as one group of complete manufacturing and install.The window leaf is fabricated onto together in single fabric side, is attached to together by easily broken seam at its longitudinal edge place, and this easily broken seam can torn under the situation of not damaging the window leaf to make each window leaf separation before installing.If the width of installing needs to manufacture more window leaves of single fabric side, then can use the window leaf of a plurality of fabric side.On the contrary, less if desired window leaf, it is unnecessary then can to abandon.

This embodiment aspect according to the present invention can be provided with continuous horizontal decorative pattern during manufacture on fabric side.Because the window leaf in the fabric side is attached to together during manufacture, can keep the vertical alignment of decorative pattern from a window leaf to next window leaf, make that horizontal decorative pattern keeps alignment after the window leaf separates and installs.

According to the present invention this embodiment on the other hand, each window leaf can have and the structure of other window leaf braiding structure independently.This allows to provide edge coil along the longitudinal edge of window leaf, thereby prevents their particularly wearing and tearing when machine washing.

According to the present invention this embodiment on the other hand, the edge coil of window leaf can be formed by high-strength yarn.Similarly, the easily broken connection between the window leaf can be formed by connecting line, and the hot strength of this connecting line is lower than the hot strength of the high-strength yarn that the adjacent windows leaf is connected together.This structure provides connection between the window leaf, this connection can be torn and do not damaged the braiding structure of window leaf.

This embodiment provides attaching but folding and sewing line can be set with the accurate repeatable position place at the suspension bracket at the place, top of each window leaf, and locates to provide suspending weight in its bottom on the other hand in the braiding structure of each window leaf according to the present invention.Similarly, can in the window impeller structure, inweave groove to allow being attached to suspension bracket with suspension hook.

According to a second embodiment of the present invention, provide a kind of combination shutter, it has opaque substantially fabric window leaf alternately and complete transparent or semitransparent fabric is isolated leaf, and each is isolated leaf isolated a pair of window leaf is connected together.The window leaf can be provided with suspension bracket at the top supporting the window leaf pivotally from horizontal bar, and can have rotation in the bottom with vertical bias window leaf.Horizontal bar allow the window leaf close and open orientation between pivoting action.

In closing the orientation, the window leaf is substantially parallel to each other and be in first common plane, and this first common plane is arranged in the plane of shutter self substantially.The side of window leaf contacts, and stops that thus light passes through shutter.Isolate leaf in same level tightly the window leaf after and before alternately extension.In open orientation, the window leaf cardinal principle and the first common plane traversed by and parallel to each other.But, isolate leaf alternately in one of two common plane that are parallel to first common plane between the window leaf horizontal-extending substantially, to allow light by isolating leaf.Only work between two window leaves the time because isolate leaf, so shutter begins and finishes with the window leaf ideally.

Shutter can also be moved the one or both sides of horizontal bar to, when parallel to each other and when being pulled together with the window leaf of shutter plane traversed by orientation, isolate leaf draw in, folding or form arc.

According to an aspect of second embodiment of the invention, the combination shutter along fabric window leaf is joined to the side of septum pellucidum from leaf be provided with the seam time hinge.The seam of hinge provides minimum contact ideally between window leaf and isolation leaf, to provide between these parts than constituting the window leaf and isolating the more flexible interface of seam of the fabric of leaf self.This window leaf and the flexibility of isolating between the leaf allow the parts of shutter relative to each other to move at the hinge place, and can not make the window leaf or isolate leaf bending in hinge, particularly during opening and closing the shutter that stretches.Alternatively or additionally, the yarn self of formation hinge seam can have bigger flexibility than the fabric of window leaf that is used to form shutter and isolation leaf.

According to second embodiment of the invention on the other hand, the window leaf of shutter, isolation leaf and hinge can form in the single knit operation on single braider.This machine can weave threads ideally simultaneously, and shutter is made into single fabric side ideally, and this fabric side has by the window leaf of isolating the sufficient amount that leaf connects to be used for whole shutter.

According to second embodiment of the invention on the other hand, hinge can also be as the window leaf of shutter and the easily broken connection between the isolation leaf.Ideally, hinge is lower than on every side by hot strength that the yarn of fabric forms, and allows thus isolating that leaf will be isolated leaf with hinge place between the window leaf with hand and the window leaf is torn, and does not damage the structure of window leaf or isolation leaf.So, can adjust during installation manufacture normal width but to concrete installation too big shutter.Preferably, make the hinge seam, be worn to prevent that side from looking all over becoming when tearing, to separate with the window leaf fully.

According to second embodiment of the invention on the other hand, the shutter fabric side can be provided with at each end of shutter and be connected to the window leaf or isolate one of leaf or both attaching bars, to be provided for that when needs are installed the shutter of broad a plurality of shutter fabric side are attached to together border.

Ideally, the attaching bar can be narrow extension, and it preferably is attached to the side of shutter fabric side by easily broken hinge.So easily broken hinge can be provided in the device of removing the attaching bar when not required and not damaging shutter, and can be used as hinge when being attached to another fabric side.Advantageously, can in the attaching bar, use the yarn that scribbles adhesive, perhaps can be after manufacturing adhesive be coated to the attaching bar.Preferably, adhesive can be by heat activation to allow using conventional iron that fabric side is attached to together.Advantageously, the attaching bar is made into the decorative pattern that can seamlessly sneak in the shutter fabric side to be attached to.

Perhaps, connection strap can be arranged between two fabric side and be directly connected to the window leaf of the edge of two fabric side.Connection strap can be attached to the terminal window leaf of fabric side to be connected by adhesive or another mechanical device.

According to second embodiment of the invention on the other hand, continuous horizontal decorative pattern can be set during manufacture on fabric side.Because the window leaf in the fabric side is attached to together and after installation during manufacture and keeps together, so can keep the vertical alignment of decorative pattern from a window leaf to next window leaf.Decorative pattern can cross over opaque window leaf and septum pellucidum extends from leaf, makes can see decorative pattern when the stretching, extension shutter is opened (only exposing transparent part) or closed (exposing the window leaf).Ideally, any decorative pattern on the transparent part should stitch all over becoming like this, is suitably transparent when closing shutter even make when closing through the isolation Ye Yeneng on the window leaf.

According to second embodiment of the invention on the other hand, middle hinge can vertically be arranged on septum pellucidum in leaf, and is also in parallel to be located between the easily broken hinge of isolating between leaf and the adjacent windows leaf.Middle hinge allows each isolation leaf folding along hinge when shutter is pulled up.Ideally, middle hinge forms in the same manner, and by with arbitrary side on easily broken hinge same yarn line form.This has simplified manufacturing, and guarantees to have in all hinges the flexibility of similarity degree.Perhaps, because middle hinge can not torn,, perhaps can differently stitch all over so that hinge more can be resisted tears with the easily broken hinge of the side edge of isolating leaf so they can be formed by more firm different yarns.

According to second embodiment of the invention on the other hand, easily broken and middle hinge can biasedly fold on specific direction.Can advantageously revise the selection of the yarn that is used for hinge and during manufacture and the processing of thereafter hinge being done, with the septum pellucidum of offering help from leaf folding bias voltage on specific direction.

According to second embodiment of the invention on the other hand, can the isolation leaf be removed from the window leaf by tearing easily broken hinge, and convert shutter to traditional vertical blind from the combination shutter.After conversion, can abandon the isolation leaf, because transfer process can't reverse.

According to an aspect of various embodiments of the present invention, a plurality of fabric side of shutter can order be made on single braider.When needs exceeded the specific shutter of single fabric side shutter width, particularly when needs were crossed over the horizontal decorative pattern of unnecessary fabric side extension, a plurality of fabric side can be favourable.In addition, other parts of vertical blind can inweave fabric side, for example can be by there not being the wearing and tearing easily broken valance that is connected and fixed (valance), and can pull down valance and not damage the remainder of shutter from fabric side by this connection.

According to various embodiments of the present invention on the other hand, each window leaf can serial number, with temporarily when shutter is pulled down the window leaf (for example when cleaning) indication of window leaf suspension order is provided to the user.Number preferably under normal circumstances sightless position and engrave in the window leaf, for example located by the top that valance blocks usually at the window leaf.Can also stamp the orientation of arrow with the indicating window leaf.Window leaf numbering is for traditional vertical blind embodiment particular importance, if especially shutter has horizontal decorative pattern.But if the combination shutter is converted into traditional shutter, then window leaf numbering also can be used for combination shutter of the present invention.

According to various embodiments of the present invention on the other hand, can economize unfolding and sewing line from the braiding structure of each window leaf, to allow accurately to align during installation the car shadow.So the window leaf can be woven into continuous volume, can roll up the fabric side that cuts out Len req continuously from this.

According to various embodiments of the present invention on the other hand, a plurality of opaque substantially auxiliary window leaves can be set, each all is arranged in the opaque window leaf of a plurality of parts after corresponding one in described a plurality of opaque substantially auxiliary window leaves.

The window leaf comprises opaque substantially article one, opaque substantially second and is arranged in transparent central strip between described article one and the second according to another embodiment of the present invention.Article one and second be connected to central strip by easily broken hinge.Can connect together with second by article one and form the vertical blind fabric side the window leaf.

In conjunction with the accompanying drawings, from following detailed description of the preferred embodiment and claims, can understand others of the present invention, feature and details more all sidedly.

The specific embodiment

The layout that comprises vertical blind first embodiment of the present invention has been shown among Fig. 1.Fig. 1 shows the single fabric side 100 of 15 window leaf 101-115 that comprise vertical blind.This curtain has the decorative pattern 120 across the fabric side width.As shown in the figure, this design decorative pattern is extended to next window leaf from a window leaf.Each window leaf of this curtain is separated to inweave single fabric side after finishing, and the correct alignment of decorative pattern is as described below when guaranteeing to install.Each window leaf 101-115 is by tearing edge strip separately, and this can be installed separately the window leaf.

Fig. 2 is a detail drawing of tearing edge strip 200 of the present invention.Shown in tear edge strip 200 vertical extent between adjacent two window leaf A and B.Shown connecting

line

2 and 3 will be torn the edge that edge strip 200 is connected respectively to window leaf A and B.Before the window leaf is installed, draws back and tear edge strip 200 with branch window leaf A and B.

The connecting line

2 and 3 that window leaf A and B is attached to edge strip 200 will separate with edge strip, stay clean and tidy edge, as following with reference to as described in the figure 3.

Fig. 3 is the schematic diagram of tearing edge strip of Fig. 2.Fabric vertically passes in pillar stitch (pillar stitch) 1, and is parallel to each other on whole fabric side width.For example, in the fabric side of Fig. 1, vertically extending pillar stitch can extend to the left side and the right of fabric side 120 on the whole width of fabric side.Preferably, pillar stitch 1 is made by high strength PE yarn.Pillar stitch 1 forms the basis of the structure of fabric side 120.In a preferred embodiment, pillar stitch 1 is that all other yarns are attached on it to form the tissue of fabric.As shown in the figure,

pillar stitch

4 and 5 represents the edge tissues of window leaf A and B respectively, and pillar stitch 4 is rightmost edges of window leaf A, and pillar stitch 5 is leftmost edge of window leaf B.As mentioned above, although Fig. 3 only shows two pillar stitches of each window leaf in a preferred embodiment, the window leaf can by for example 30 or more pillar stitches form.

On the contrary, tear edge strip 200 and formed by 2 pillar stitches 201 and 202, described pillar stitch is preferred structurally identical with the pillar stitch that constitutes window leaf A and B.Shown in connecting

line

2 and 3

pillar stitch

4 and 5 is connected to tears edge strip 200

respectively.Connecting line

2 and 3 passes along the continuity of the directions of approximate vertical and tears edge strip 200, and passes tearing between edge strip 200 and

pillar stitch

4 and 5 to set decorative pattern.

Particularly, as shown in Figure 3, connecting line 2 passes between

pillar stitch

201 and 202, and is in to tear between edge strip 200 and the pillar stitch 4 in

position

204 and 206 and passes.Similarly, connecting line 3 is in to tear between edge strip 200 and the pillar stitch 5 in

position

208 and 210 and passes.But different with connecting line 2, connecting line 3 does not pass between two pillar stitches 201 that tear

edge strip

200 and 202, but only passes between pillar stitch 202 and 5.In the connecting

line

2 and 3 be one or a plurality of between

pillar stitch

201 and 202, pass unimportant, but because connecting

line

2 and 3 is window leaf A and B and tear only connection the between the edge strip 200, so connecting

line

2 and 3 one of must pass respectively in the pillar stitch of window leaf A and B at least, is preferably the pillar stitch of passing its edge.Therefore, connecting

line

2 and 3 is that window leaf A and B are attached to together only connection.

Ideally, connecting

line

2 and 3 is made by the low filament yarn of high strength PE yarn hot strength that has than being used to form pillar stitch 1.Fig. 4 shows in further detail to form between window leaf A and B and tears the pillar stitch of edge strip 200 and the position of connecting line.

Fig. 5 is the schematic diagram similar with Fig. 3, with respect to the connecting line of tearing in the edge strip 200 2 and 3, and possible the passing of other decorative pattern yarn 7 shown in broken lines.Decorative pattern yarn 7 is used for only passing between the pillar stitch 1 of window leaf A and B.These decorative pattern yarns 7 provide intensity and opacity for window leaf A and B just.But, the decorative pattern yarn do not penetrate tear in the edge strip 200 unimportant.On the contrary, tear edge strip 200 and can have

decorative pattern yarn

7a, 7a, the intensity of tearing edge strip with raising, but

decorative pattern yarn

7a, 7a do not penetrate in the pillar stitch that constitutes window leaf A and B similarly.

In order to divide window leaf A and B, will tear edge strip 200 and pull out from fabric.The low connecting

line

2 and 3 of pillar stitch will rupture around the hot strength ratio, thereby window leaf A is separated with B.In a preferred embodiment, connecting

line

2 and 3 and

pillar stitch

201 and 202 more closely twine, and just twine slightly with pillar stitch 4 and 5.As a result, when when fabric is torn, the residue of connecting

line

2 and 3 fracture more may be stayed and tear in the edge strip 200.Owing to tear edge strip 200 and will abandon, and window leaf A and B does not still have loose the end of a thread and can use immediately, so this is favourable.Additional advantage is produced by the structure of

window leaf

2 and 3, and this structure can just not die down because of removing connecting

line

2 and 3 owing to constitute the independent pillar stitch 1 of window leaf A and B.On the contrary, with respect to the structure of window leaf, connecting line is unnecessary, and it just is used for the window leaf linked together becomes single fabric side.This absolute construction has caused can be along with the past of time or owing to the clean and tidy edge of machine-washing and wearing and tearing.

By connecting into integral fabric face as shown in Figure 1 from one group of window leaf of single vertical blind,, fabric side simplified the braiding that designs decorative pattern across the level of fabric side widely because can processing simultaneously, and can be so that to the control of horizontal alignment and the length unification of fabric.The result just obtains having the vertical blind of continuous outward appearance and moving reveal competence decorative pattern.

As shown in Figure 6, the cutting line place between fabric side bottom 120A and fabric side top 120B shows the part of fabric side 120.Particularly, show by the fabric side 101 to 105 of fabric side 120A and 120B being divided the horizon 130 opened define.Also can see the end that defines a window leaf and another window leaf beginning tear edge strip 200.The top of broken line 132 expression window leaves 101 to 105 is folded the place to allow inserting suspension bracket or the hardware (not shown) is installed.Hole 134 can be set alternatively, pass the window leaf to allow that suspension hook is installed.Line 136 expressions on the bottom are used for bottom the folding of suspending weight makes a little, and the bottom suspending weight can be provided with the performance that improves the window leaf alternatively.

Ideally, after the braiding of fabric side is finished, but before delivering goods the shutter of finishing to client, bottom suspending weight and top suspension bracket are installed.The installation of various hardware need not window leaf 101 to 105 separated from one another, even but before client is given in delivery with the window leaf separately, inweave the installation that unique window leaf number-mark in each window leaf 101 to 105 has also been simplified shutter.In addition, the serial number of this mode of window leaf allows shutter is taken apart, for example, in order to clean the purpose of window leaf, and correctly in proper order problem of window leaf can not occur not knowing when re-assembly shutter.

Ideally, single window leaf fabric side is processed into enough width, to provide single shutter required window number of sheets order.But, can be made into the more window leaf of single fabric side if application-specific requires shutter to have than reality, can process so have requirement window leaf the continuous web face to finish shutter.As shown in Figure 7, show the continuous web face 220 of wherein making fenestrate leaf 116 to 125.The window leaf of continuous web face 120 is made in the mode identical with window leaf 101-105, and promptly these window leaves are provided with horizontal folding edge strip is vertical to be separated with sewing line and by tearing.In addition, if continuous horizontal decorative pattern is set in last fabric side, continuous web face 220 can have continuous horizontal decorative pattern so, as shown in Figure 7.

In addition, also can in continuous web face 220, inweave parts, for example when on last fabric side, having enough spaces to comprise valance as valance and so on.Ideally, valance 230 inweaves in the continuous web face 220 in the mode identical with single window leaf, particularly, and by inweaving so that separate valance 230 from the edge strip of tearing that fabric side 220 is drawn back.

Horizontal little difference comprises during the vertical blind that is formed on two window leaves on the separation fabric side in installation, owing to may appear in the normal variation in the weaving between fabric side.Little horizontal-shift appears in the result between the window leaf of the window leaf of a fabric side and another fabric side.Significant difference can be seen at once, especially when the window leaf of crossing over shutter is provided with continuous horizontal decorative pattern.

Because many factors, for example machine tension force, yarn and the variation of the environment of plant on every side change in size can occur naturally in weaving.This size drift finishes to occur in the mode that progressively increases to it from the operation beginning usually in whole manufacturing process.Therefore, first fabric side and in service second or the 3rd fabric side that the manufacturing run duration is made may have only slight skew, and the difference between first fabric side and last fabric side may be more remarkable.Therefore, the fabric side in many fabric side shutter should be made at same manufacturing run duration, preferably makes each continuous web face make at once after last fabric side.

Selectively, the window leaf can manufacture had not both had broken line 132, did not have sewing line 136 yet.For example, when the width of design motif than in single fabric side, making side by side when needing more window leaf, by before making the groove that is used to insert the bottom suspending weight, the window leaf being cut into unified length, can compensate the manufacturing variable.Therefore, the window leaf that is made into by the fabric side of separating will correctly be arranged.

The layout of second embodiment that comprises vertical blind of the present invention has been shown among Fig. 8 A-8D.Fig. 9 A-9D is totally corresponding to Fig. 8 A-8D, shows the schematic diagram of operation of the shutter of second embodiment.Shutter 300 is isolated the combination shutter of leaf 320 for having the bright or translucent fabric of opaque substantially fabric window leaf 310 alternately and full impregnated, and each is isolated leaf 320 a pair of isolated window leaf 310 is linked together.The window leaf can be provided with suspension bracket at the top, and supporting window leaf 310 pivotly from horizontal bar 332, and the window leaf can have the suspending weight (not shown) in the bottom, with bias voltage window leaf vertically.Horizontal bar 332 allows window leaf 310 to move pivotally between the opening and closing orientation.

Fig. 8 A and 9A show open orientation, wherein window leaf 310 substantially and horizontal bar 332 traversed bies, and parallel to each other.It is parallel to each other substantially to isolate leaf 320, alternately in one of two common plane that are parallel to horizontal bar 332 between window leaf 310 horizontal-extending.Isolate leaf 320 and allow light to pass through, and the traversed by orientation of opaque window leaf 310 allows light to pass from it.

Fig. 8 B and 9B show and are in the shutter of the present invention that the orientation is closed in the part.Window leaf 310 is in the rotation of suspension hook 330 places, to depart from from the traversed by orientation that limits open position.Although it is parallel that the consistent window leaf 310 that rotates is still, because the angle of window leaf 310 has partly light now and blocks.Similarly, isolate leaf 320 and just partly block,, still allow some light to pass although therefore lack than open position.

Fig. 8 C and 9C show the shutter 300 of further closing.In this position, window leaf 310 is further rotated from its initial traversed by orientation, has therefore blocked more rays.Although window leaf 310 almost is parallel to horizontal bar 332 now, they are still parallel, thereby show decorative pattern on the surface of window leaf 310.Similarly, isolate leaf 320 and almost stopped, but still allow some light to pass by the action of window leaf 310.

Fig. 8 D and 9D show and are in the shutter 300 of closing the orientation fully.Window leaf 310 has rotated 90 ° from its initial traversed by orientation, is parallel to horizontal bar 332 now.Distance between the window leaf 310 is less than or equal to its width, so window leaf 310 is overlapping, has blocked light basically fully and has passed through from it.On the window leaf 310 that replaces, still can see and isolate leaf 320, but because the position of window leaf 310 does not have light to pass isolation leaf 320.

As shown in Figure 10 a to 10c, shutter 300 also can be moved the one or both sides of horizontal bar 332 to.Figure 10 a shows the shutter 300 of the full extension that window leaf 310 wherein is shown in an open position.Show hinge 312 and middle hinge 322 between window leaf 310 and the isolation leaf 320.

Figure 10 b shows the shutter 300 that partly pulls to a side.When pulling shutter 300, leaf 320 is folding along inside direction along with isolating, and can see the operation of easily broken hinge 312 and 322.Figure 10 c shows and pulls to the shutter 300 of a side to the mechanical limit of horizontal bar 332 fully, shows window leaf 310 and isolates the mode that leaf 320 is folded each other.

Figure 11 shows linkage of the present invention in further detail.Shown in isolate leaf 320 is attached to window leaf 310 by hinge 312 either side.Isolate leaf 320 and middle hinge 322 and extend perpendicularly to the bottom from the top that isolates leaf 320.

Figure 12 is the schematic diagram of easily broken hinge 312.The pillar stitch of the rightmost side in leaf 320 structures is isolated in mark 9 expressions.The quantity that constitutes the pillar stitch that isolates leaf depends on the width and the profile of isolating leaf, and the typical amounts of pillar stitch is about 25.But,, not remarkable to the quantity that constitutes the pillar stitch that isolates leaf for purpose of the present invention.For for simplicity, only show three pillar stitches that isolate in the leaf 320.The pillar stitch of the leftmost side also only shows its three pillar stitches in the mark 10 expression window leaves 310 among Figure 12.The connecting line 8 that forms hinge 312 structures passes the pillar stitch that isolates leaf 320 edges, and also passes the interval 12 that isolates between leaf 320 and the window leaf 310 in the place that needs formation connects.Connecting line is to pass this unique yarn at interval.This layout has formed easily broken hinge 312 just, and window leaf and isolation leaf fold along this easily broken hinge 312.

Preferably, middle hinge 322 is made in the same way, and is therefore similarly easily broken.The setting of middle hinge 322 defines isolates the mode that leaf 320 folds when pulling shutter 300.Therefore, can omit hinge 322 fully, a plurality of hinges perhaps can be set to produce many Zhe shape decorative pattern to produce soft edge.

The frequency and the quantity that form the connection of easily broken hinge can change.This makes it possible to regulate intensity, hinge flexible of connection and comprise hinge in design.

Preferably, comprise that 9 and 10 pillar stitch is formed by high-strength yarn, and connecting line 8 is preferably and has more low intensive yarn, thus make be hinged 312 easily broken.Connecting line 8 uses more low intensive yarn (being preferably filament yarn) to provide the permission hinge to have the additional advantage of preferred folding direction or memory.Can be by folding along required preferred orientations and allow them to remain on this position a period of time to realize this advantage, for example in the encapsulation of carrying or selling.

Figure 13 shows the linkage identical with Figure 12, but Figure 12 only shows pillar stitch and single connecting line, and Figure 13 shows the preferential direction of the additional yarn 11 of passing the pillar stitch that isolates leaf 320 and window leaf 310 respectively.Yarn 11 has increased the profile of cloth construction, but does not pass the interval that isolates between leaf 320 and the window leaf 310.Have only connecting line 8 to pass this at interval.Therefore, with disclosed among the embodiment of front to tear edge strip similar, tear fabric if the structure of easily broken hinge 312 makes at 12 places at interval, connecting line can rupture so, separates from window leaf 310 thereby allow to isolate leaf 320.As shown in Figure 12 and 13, connecting line 8 more closely twines with the pillar stitch 9 that isolates leaf 320, and just twines slightly with the pillar stitch 10 of window leaf 310.This structure has improved when window leaf 320 is torn with isolation leaf 310, isolates the possibility that stays clean and tidy edge in the leaf 320 on window leaf 310 thereby the residual wires of the connecting line of tearing 8 still is embedded in.

Because combination shutter 300 by single fabric side manufacturing, so ideally, has permission window leaf 310 rotates to fastening position from open position mechanism.In addition, ideally, have, make and isolate can be folded each other together device of leaf 320 at pulling shutter and the window leaf is collected in a time-out.

Therefore, easily broken hinge 312 is used for two purposes.The first, easily broken hinge is as the hinge components that window leaf 310 is connected to flexibly isolation leaf 320, and the relative motion between permission window leaf and the isolation leaf, limits any warpage of fabric with respect to easily broken hinge simultaneously.As mentioned above, preferably, the selected yarn types that is used as connecting line 8 is the type more soft more inherently than the yarn that is used to form surrounding structure and pillar stitch.This is equally applicable to the easily broken middle hinge 322 that can construct in the same manner.

Second function of easily broken hinge 312 is to allow to tear the part shutter and do not damage its any parts.For example, peelable and abandon unnecessary window leaf and isolate leaf when the shutter of making in single fabric side is too wide for concrete application, remaining shutter has required width.Easily broken hinge also makes and can tear and abandon from single fabric side by simply each being isolated leaf 320, and stay a plurality of window leaves 310 that work with window leaf same way as with the first embodiment vertical blind, and convert each combination shutter to traditional vertical blind.As shown in Figure 14-16, the design of combination shutter 300 is included in easily broken hinge 312 places and isolates leaf 320 seamless links a plurality of fabric window leaves 310 together by transparent fabric.When making, each shutter fabric side 300 is at window leaf 310 or isolate beginning and end in the leaf 320.As a result, two or more fabric side can link together side by side, with the horizontal bar of the random length that adapts to the window leaf with any desired or needs quantity.Therefore, ideally, combination shutter fabric side is processed into two kinds of patterns.First pattern 300 begins and finishes with window leaf 310, and is used for any installation.The second pattern 300A is to isolate leaf 320 beginnings and to finish.The thin fabric strip 350 of imitated decorative pattern along window leaf 310 edges is attached to terminal outer ledge of isolating leaf 320 by mentioned hinge 312.

The fabric side of combination shutter can two kinds a kind of linking together in the method.In first method, inweave hot melt bonding yarn silk in the cloth construction on the downside of slice 350.Slice 350 can heat (for example, using traditional family expenses flatiron) fusing binder yarns then in the edge top layering of the terminal window leaf 310 of shutter fabric side 300, thereby slice 350 is adhered to the edge of the window leaf 310 of shutter fabric side 300.In the second approach, can be with film formed the downside that adheres to slice 350 that bond by hot melt.Can be slice 350 be bonded to the window leaf 310 of shutter fabric side 300 with the bonding mould with the similar mode of first method.

As shown in Figure 14, the shutter fabric side 300A that has window leaf alternately 310 and isolation leaf 320 shown in finishes at isolation leaf 320 places that are being connected to slice 350 by easily broken hinge 312.As shown in Figure 15, the slice 350 of shutter fabric side 300A is arranged to adjacent with the terminal window leaf 310 of shutter fabric side 300.

Figure 16 is illustrated in the layout of the slice 350 on the edge of window leaf 310 of shutter fabric side 300.After by this way fabric side being bonded together, shutter fabric side 300A go up between terminal isolation leaf 310 and the slice 350 easily broken hinge 312 with and remaining window leaf of shutter and isolation leaf between the identical mode of easily broken hinge work.Therefore, with shutter fabric side 300A with 300 after slice 350 places combine, the fabric side of combination is as single vertical cartel shutter.

Figure 17 shows connect the improvement of the method for two or more fabric side in shutter.Shown in the shutter fabric side 300b that has window leaf 310 alternately and isolate leaf 320 end among the improved window leaf 310b, wherein window leaf 310b is provided with slice 350b, and this slice 350b is attached between window leaf 310b and the adjacent isolation leaf 320 by the easily broken hinge 312 on each side.This is with only to be connected to the not improvement window leaf 310 of adjacent isolation leaf 320 by easily broken hinge 312 different.

In this embodiment, the window leaf of fabric side 300b can be used as terminal window leaf about the similar mode of shutter fabric side 300 with above-mentioned in device.If use by this way, in this device, terminal window leaf 310b will look slightly different with other window leaf so, but and not obvious.Ideally, when window leaf 310 was provided with upholstery border 313, slice 350b can be woven into the decorative pattern similar with upholstery border 313.Therefore, slice 350b visually can be similar to upholstery border, makes that the change of window leaf 310b is so unobvious.

Selectively, window leaf 310b can tear from slice 350b along the easily broken hinge 312 between window leaf 310b and the slice 350b.This step has only stayed and has been attached to the slice 350b of septum pellucidum from leaf 320 ends.Then, can use aforementioned hot fusibleness adhesive method this slice 350b to be attached to the terminal window leaf of another fabric side 300b (or 300).

The advantage of this embodiment is, because shutter fabric side 300b both can use separately, also can be used in combination with its another fabric side 300b that directly is attached to, and sells in pairs and is used for attaching so need not to produce two kinds of different fabric side (for example 300 and 300a).Thereby to need not to provide not be to be designed for the shutter fabric side 300a that is attached to another shutter fabric side.This has simplified manufacturing, and need not to provide second kind of product to the user.

Can use multiple adhesive to make slice 350 have viscosity.For example, comprise by FallRiver, Mass. the hot melt bonding coat yarn of the piece number 90X312116 that Engineered Yarns Company produces is exactly the yarn that is provided with the polyamide hot melt coatings, and this coating is suitable for the fabric that bonds under the temperature between 280 and 300 .Selectively, hot melt bonding strip (for example by Shirely, the piece number that the Bemis of Mass. produces is 3410 transparent polyurethane) also is suitable for boning shutter fabric side 300A.Those skilled in the art can know other adhesive that is suitable for fabric, to realize identical purpose.

Fabric side also can use the connection strap 500 shown in Figure 18 to engage.Each method of aforementioned joint fabric side comprises gluing or bonding, and this point has been avoided in the use of connection strap 500.

As shown in Figure 18, connection strap shown in 500 is formed from leaf by hinge 312 septum pellucidums side by side connected to one another by three.Ideally, the isolation leaf 320 with the shutter fabric side 300 that will link together is identical in design for center band 520.Left side band need not to have identical decorative pattern with right with 510, and more transparent ideally.Ideally, the left side band and the right side are clean and tidy with 510 outer rim 514, but they can be to be partitioned into from bigger fabric side.For example, can in single fabric side, make by easily broken hinge as 312 attachings, many connection straps 500 separated from one another thereafter.In connection strap 500, by folding fabric and make straight seam and can form top edging and end edging (not shown).Preferably, edging will be formed for inserting the groove of suspension bracket reinforcing section at the top, and be formed for inserting another groove of bottom suspending weight in the bottom.Top at left side and right side band 510 also cuts out the recess (not shown), as the gap of suspension hook.

Assemble two shutter fabric side by following such use connection strap 500, be about to a left side with 510 back that place shutter fabric side rightmost side window leaf, by the top reinforcing section is passed the top edging and is with 510 to connect rail to the end on a left side, again with the top reinforcing section attaching window leaf suspension bracket on the rail to the end.Then, to the right side be with 510 and another frivolous shutter fabric side leftmost side window leaf repeat above-mentioned installation steps.Suspending weight can be inserted then by in the left side band of connection strap 500 and the right groove that forms with 510 end edging.

Combinations thereof shutter shown in Fig. 8-18 provides the degree that can shut out the light according to window leaf 310 and has changed the blind system that enters the indoor light amount.But, generally also can allow some light to pass even weave abundant fabric, so the combinations thereof shutter refers to the shutter that darkens the room of using and not exclusively stop light for all.

Figure 19 shows and is used for the auxiliary window leaf 410 that the present invention makes up the embodiment that darkens the room of shutter 300.Auxiliary window leaf 410 can be made by the material that PVC, timber, aluminium or any other rigidity and opacity are fit to, and it manufactures and is suspended on standard vertical shutter head rail (for example horizontal bar 332) upward as vertical blind window leaf.These auxiliary window leaves will be suspended on a rail identical with the combinations thereof shutter, and will be positioned at after the opaque fabric window leaf 310 and paired with it.Ideally, this can be by reaching with the auxiliary window leaf 410 of the mode attaching identical with the shutter fabric side.Then, can for example use the clasp band (hook-and-loop tape) 412 of the adhesive-backet that is arranged on place, auxiliary window leaf 410 bottoms fabric window leaf 310 to be attached to the bottom of assisting window leaf 410.As shown in Figure 20, the hasp of clasp band 412 partly is attached to auxiliary window leaf 410, then with fabric window leaf by being pressed on the clasp band.Because fabric window leaf itself directly is bonded to the hasp part of clasp band 412 as taking ring, to take the loop section possibility accordingly dispensable so use.Selectively, can use the bottom of plastic clip (for example plastic grip shown in Figure 21 415) with the auxiliary window leaf 410 of fabric window leaf attaching.The openend of clip 415 upwards slides on the base of window leaf 310, makes fabric window leaf and rigidity window leaf all be stuck in the clip of clip 415.Ideally, each window leaf has two clips.

Ideally, auxiliary window leaf 410 is arranged on the back of fabric window leaf 310, promptly is arranged between shutter and the window, to prevent easily to assist window leaf 410 from indoor seeing.Figure 22 shows fully the embodiment that darkens the room of the present invention of assembling, and it has the auxiliary window leaf 410 that is suspended on a rail identical with fabric window leaf 310 and is arranged in fabric window leaf back.

In the embodiment that darkens the room of the present invention, also can use above-mentioned connection strap 500 that the shutter fabric side is attached to together.As shown in Figure 23, the left side of connection strap 500 is with 510 back that can place the rightmost side fabric window leaf 310 of a shutter fabric side, but in the front of auxiliary window leaf 410, the right side can be arranged between the rightmost side fabric window leaf 310 and auxiliary window leaf 410 of another shutter fabric side similarly with 510.Preferably, auxiliary window leaf 410, fabric window leaf 310 and be with 510 by same hanger suspending on a rail.As shown in Figure 24, in the bottom, be with 510 by being with 310 to be attached on the clasp band 412 on the auxiliary window leaf 410 by being pressed in.Some hasps of thin thin permission clasp band 412 with 510 stretch out to pass is with 510, thereby allows fabric window leaf 310 also by being with 510 to be attached on the clasp band 412, as shown in Figure 25.Selectively, can use the clip that is attached to the shutter bottom that fabric window leaf 310 and auxiliary window leaf 410 are attached to together.

If the quantity of window leaf causes the back exposure of window leaf in the combination shutter, two fabric window leaf 310c then can be set, as shown in Figure 26.Particularly, the 300c of shutter shown in is provided with two fabric window leaf 310c.Two fabric window leaf 310c comprise adjacent one another are and by as two general window leaves 310 of easily broken hinge 312 attachings.As shown in Figure 27, when assembling, two fabric window leaf 310c are folded on the auxiliary window leaf 410, and use the clasp securing member to be fixed to auxiliary window leaf.Also can advantageously use clip.This structure has prevented to install afterwards from seeing the auxiliary window leaf 410 of shutter end within doors.

The combinations thereof shutter also can have been made broken line and sewing line inserting bottom suspending weight, suspension bracket or other installs hardware, but have with front embodiment in the identical difficulty of suitably aliging of keeping during manufacture.In fact, in the combination shutter, when two or more fabric side were bonded together, the alignment error of window leaf bottom was especially obvious.Therefore, the fabric side of present embodiment can not have broken line or sewing line, especially in the bottom of window leaf.Therefore, fabric side can cut into unified length, thereby the intersection between two fabric side provides suitable alignment.

The other advantage of eliminating broken line and sewing line is that the shutter of present embodiment can be made continuously.Therefore, but rolling the shutter fabric is provided, shutter can cut into designated length and make specified width, which width from this fabric.This flexibility is particularly useful when manufacturer or third party producer wish to make shutter to can be used for random length.

For example, under the situation of the embodiment of the invention, the shutter fabric ideally by providing with replacing continuous oolemma 320 and window leaf band 310 rolling, and wherein oolemma and window leaf band are by above-mentioned linkage separately.Then, manufacturer or producer cut into required length with fabric, as required in top and bottom fold with make, to be formed for the groove of top suspension bracket reinforcing section and bottom suspending weight.Ideally, the linkage of the fabric shutter of this manufacturing is same as described above, but the hole that is used for the suspension bracket suspension hook must be cut at window leaf top after making by hand.

For further flexibility being provided for client aspect the dimensional requirement, the vertical blind fabric side of another exemplary embodiment can be by comprising that three the window leaf that connects side by side by easily broken hinge makes, as shown in Figure 28 according to the present invention.In more detail, window leaf 700 comprises end bar 710,712 and is arranged in the central strip 714 of holding between the bar 710 and 712.End bar 710,712 is preferably opaque fabric strip, and central strip 714 is preferably as the transparent fabric bar of isolating leaf.Window leaf 700 can manufacture continuous length and not have top or bottom slitter marks, and perhaps slitter marks can be designed for the Fabric Design that top and/or bottom cut the position.As shown in Figure 28, after window leaf 700 cropped one-tenth Len reqs, with them along the top fold of inserting the suspension bracket reinforcing section and make.Preferably, in each end bar 710,712, be formed for the recess in suspension hook gap.And, as shown in Figure 29, in order to insert bottom suspending weight or other necessary hardware along the base, at bottom fold window leaf 700 and make.Window leaf 700 can be made in central strip 714 and/or end bar 710,712 the design decorative pattern.

Preferably, the installation of the vertical blind of being made by window leaf 700 needs the quantity of the suspension hook of attaching window leaf on quantity and the rail to equate or less window leaf 700.As shown in Figure 30, begin at the suspension hook place of the leftmost side, by suspension hook being passed in the groove on the reinforcing section of top and the left end bar 710a of the attaching first window leaf 700a, this top reinforcing section inserts taking in the ring on the top margin of left end bar 710a.Next suspension hook place on the right side, the left end bar 710b of right-hand member bar 712a and the second window leaf 700b is attaching mutually.Continue this process, two end bars 710,712 are attached to next suspension hook, at every turn till the suspension hook that reaches the rightmost side.At this moment, last window leaf 700 has only right-hand member bar 712 to insert in the rightest suspension hook.

Attaching window leaf 700 makes the transparent central strip 714 of link bar 710,712 always in the front side, and wherein this front side is the window or an external light source side farthest of blocking apart from by shutter.Owing to be space observation shutter internally, so this has produced continuous transparent fabric facial contour.

Finishing the necessary hardware that is positioned at window leaf 700 bottoms of installation can change.For example, as shown in Figure 31, suspending weight 720 can insert and be sewn in the groove of respectively holding bar 710,712 bottoms.Then, can use the bottom of plastic grip 730 bar that each is adjacent 710,712 to be attached to together, as shown in Figure 32.This structure makes the bottom of device more stable, and has kept the fabric side outward appearance when shutter or air movement blow shutter handling.Selectively, can use suspending weight and magnet apparatus to substitute clip, perhaps can not use the attaching device.

Because transparent intermediate isolating leaf 714 is towards location, the place ahead, so the shutter of opening has the appearance of fabrics across the transparent curtain on window or doorway.In this position, the light of injecting is scattered, and shutter keeps more or less transparent.Rotate opaque fabric end bar 710,712, make them be parallel to the plane of light source, this can reduce the light amount of passing shutter.

What the machine that uses in the vertical blind embodiment that makes the easily broken connection of the above-mentioned the present invention of comprising was the most common is tricot machine.Can the best be defined as through compiling by forming coil and form fabric from single yarn along warp thread direction.The yarn of coil and these coils of formation is continuous, and vertically passes fabric along warp thread direction.This just will be through compiling and circular knitting having separated that is also referred to as weft knitting, and coil and yarn flatly pass fabric along weft direction in the latter.Owing to make the warp thread of the vertical hand-manipulating of needle and the interconnected fabric that forms of weft yarn of the horizontal hand-manipulating of needle not have coil by last/following mode, complete difference so it is weaved.

More specifically, the preferred jacquard weave formula tricot machine that uses in producing above-mentioned shutter.The decorative pattern that jacquard weave formula tricot machine allows the fabric of combination through compiling to form mechanism and jacquard systems forms ability.Those skilled in the art can know understanding, has many dissimilar machines in this group.The example of jacquard weave formula tricot machine is Karl Mayer ModelRJC3/2F and the Karl Mayer Model RJCE 4/2F of the Karl Mayer GmbH of Germany.

Karl Mayer Model RJC3/2F is the two jacquard weave formula tricot machines of 3 sley bars.The specification of this machine is per inch 18 pins, can be used for producing the shutter of " thin specification ", but it also can be set at other specification.Two jacquard weave features provide the flexibility of two full-jacquard mechanisms that separate fully.One of full-jacquard mechanism only is used for decorative pattern.Another both had been used for decorative pattern, the connecting line that also is used for producing above-mentioned easily broken hinge He tears edge strip.

Sley bar with 3 separation is handled yarn to inweave in the fabric.Two is above-mentioned jacquard guide bar.The 3rd for producing the sley bar of pillar stitch.The different yarn of can packing in the position of each sley bar is to produce additional contrast in decorative pattern.

Usually, the jacquard guide bar 1 thicker yarn of can packing into, the perhaps combination of thick line and fine rule, the jacquard guide bar 2 thinner yarn of can packing into, and can pack into the yarn of the mechanical requirements that meets the fabric that to make of the chaining sley bar that produces fabric basic structure.

Karl Mayer Model RJCE4/2F is the two jacquard weave formula tricot machines of 4 sley bars.The specification of this machine is per inch 9 pins, can be used for producing the shutter of " thick specification ", but it also can be set at other specification.Two jacquard weave features provide the flexibility of two full-jacquard mechanisms that separate fully.One of full-jacquard mechanism only is used for decorative pattern.Another both had been used for decorative pattern, the connecting line that also is used for producing above-mentioned easily broken hinge He tears edge strip.

Sley bar with 4 separation is handled yarn to inweave in the fabric.Two is above-mentioned jacquard guide bar.The 3rd for producing the sley bar of pillar stitch.The 4th for embedding the sley bar of the stable yarn be used to increase rigidity.The different yarn of can packing in the position of each sley bar is to produce additional contrast in decorative pattern.

Usually, the jacquard guide bar 1 thicker yarn of can packing into, the perhaps combination of thick line and fine rule, the jacquard guide bar 2 thinner yarn of can packing into, and produce can pack into the yarn of the mechanical requirements that meets the fabric that will make of the chaining sley bar of fabric basic structure and stable sley bar.

Many different yarns combinations of making these shutters all are fine, and those skilled in the art will know these very much.A kind of yarn combination of using on the RJC3/2F machine is as follows:

Jacquard guide bar 1:300 danier, 68 ultimate fibres, semimat, distortion polyester.This is to be used to produce thick Pattern Design and the textured yarn of opacity to be provided for the louvered window leaf.

Jacquard guide bar 2:50 danier, 24 ultimate fibres, semimat, ultimate fibre polyester, regular tenacity.This be used to produce some effect of decorative patterns and be used for easily broken hinge and tear edge strip connecting line than fine yarn.The crucial specification of this yarn is its hot strength, and this hot strength is lower than the hot strength of the yarn that is used to produce pillar stitch.

Sley bar 3:70 danier, semimat, distortion polyester, high strength.This is the yarn that is used to form as the pillar stitch of fabric basic structure.High-strength yarn is used to improve intensity, and guarantees that cloth construction can not damage when separating the window leaf.

Second kind of yarn combination using on the RJCE4/2F machine is as follows: jacquard guide bar 1, top: 150 daniers, 50 ultimate fibre polyester.This is to be used for uniting use to produce the thick effect of decorative patterns of contrast and the medium yarn of opacity to be provided for the louvered window leaf with other yarn.

Jacquard guide bar 1, the bottom: 3 strands, 150 daniers, 34 ultimate fibre polyester.This be with top top jacquard guide bar 1 in yarn unite the very thick yarn of use.

Jacquard guide bar 2:70 Denier polyester, regular tenacity.This be used to produce some effect of decorative patterns and be used for easily broken hinge and tear edge strip connecting line than fine yarn.

Sley bar 4:70 danier, semimat, distortion polyester, high strength.This yarn is as the stable yarn that increases rigidity to fabric.

Yarn strength is defined as the peak load that can apply before the yarn breakage, represents with gram/danier.When the PE yarn of more different daniers, thick more yarn (high more danier) is just solid more.But, owing to intensity is represented with gram/danier, so they may have identical strength grade.Therefore, so that make a kind of yarn more solid than another kind, Cai intensity is important when having only the danier of two kinds of yarns roughly the same.Be the comparison of PE yarn of two kind of 70 danier of same provider below, a kind of is regular tenacity, and a kind of is high strength.The Dillon Yarn Corporation of Patterson of the free yarn of these copying datas manufacturer, result of the test that New Jersey provides and yarn specification.High-strength yarn has improved 22.7% than regular tenacity yarn on intensity.
