Description

For shading shop windows, seats, patios, Balconies and the like, but also conservatories very often wipes used when not in use, e.g. B. at night or in rainy weather, on a cloth wave be wrapped and for mechanical use Devices are unwound from the cloth shaft and over of the area to be shaded. For the up wrapping the cloth is the cloth shaft with a handbe made or with a machine-operated drive equips. For unwinding the cloth from the cloth shaft and for the stretching is the edge turned away from the fabric shaft of the cloth with a so-called drop bar. At Awnings, the drop bar is generally springy stressed articulated arms held with a projection the awning is possible up to approx. 4 m. At the winter garden The drop bar is usually in shade Guided tours and a counter-pull system, usually a Cable system, both in the pull-out direction and in the Retraction direction moved. With such a return system an outreach of up to approx. 7 m is possible. The awning covers and conservatory shading are the following For the sake of simplicity, only referred to as awning covers.

Sheets of fabric are used for the awning fabrics are usually 1.2 m wide. Because awnings and winter garden shading generally a greater width than 1.2 m, the awning fabric must consist of several fabric sheets be put together. At the connection points each two adjacent sheets of cloth along each other turned longitudinal edge with an overlap of about 2 cm superimposed and sewn together with two longitudinal seams,  which are called connecting seams in the following. To the both outer edges of the awning fabric will be with the two the outer longitudinal edge by about Turned 3 to 5 cm and also with two or more Longitudinal seams sewn, which are called seam seams below become. In the area of the connection seams and hem seams the awning fabric is twice as thick as the remaining surface areas, with the sutures still a certain additional thickening of the awning fabric come in addition. This has several disadvantages.

When winding on the cloth shaft, the cloth wrap has in the Double seam area and hemstitch area Thickness and therefore a greater circumferential length than in the Areas in between. This will put the cloth in the Seam areas stronger and less in the intermediate areas very excited. Due to this different tension ent are mainly in the vicinity of the seam areas Wrinkles that look like a waffle or herringbone pattern and especially when the awning fabric is partially open give a very poor aesthetic impression, as with some illustrations of the writing "The awning cloth, limits der Web- und Konfektionstechnik ", 4th edition, January 1985, which can be seen from Bundesverband Kunststoff- und Schwewebebekauffertigung e. V. Düsseldorf is published.

In the seam areas, the awning fabric has double ten cloth layer in the longitudinal direction a larger shape hold than in the intermediate areas. If over time the equipment of the awning cloth is reduced and that Awning cloth loses its stiffness and it is softer and becomes more unstable, it depends on the influence of wind and rain in the intermediate areas more than in the seam areas. The awning cloth looks as if it is in the Seam areas supported by mechanical reinforcements. It creates a kind of hammock effect. With a small length If the awning is inclined, the water bag becomes rainy education strengthened.  

With large overhangs, as is the case with conservatory shading with a counter-pull system is possible, a relationship moderately large cloth tension are applied so that the cloth looks reasonably neat when stretched.

On the one hand the unequal tensions in the seam areas and on the other hand in the intermediate areas comes up wrap such a cloth so that the cloth shaft and the drop rod bend elastically and in give way more in the middle than in the end areas. Thereby a larger area is created in the area of the seams Tension than in the area of the seams, from the Not to mention intermediate areas. This will make it Area of the seam seams tighter on the cloth shaft wraps than in the intermediate areas. The in turn has the consequence that the cloth in the area of the hem seams is stretched more, first elastic, what but over time a more permanent stretch of the Awning fabric. The awning cloth is therefore in the Area of its seams gradually longer than in the wider interior areas. This causes the marion to hang Cloth stretched laterally through in the open state. At Wind tends to flutter around the edges. In the case of conservatory shading, this can sag more the outer areas cause the awning fabric to the outer surfaces of the winter garden and its glass panes rests and rubs against it under the influence of wind.

Another problem is the seams because of their Sewing threads often increase strength over time decreases than with the awning fabric. This allows the seams, at least in sections. At these points the awning fabric is permeable to rain and wind. The life The duration of an awning of a conventional type is therefore usually extended determines the lifespan of their seams.

The invention has for its object a method specify with which individual sheets of cloth to a cloth, esp in particular to form an awning cover in the area of the connecting seams and hem seams a thickening of the awning fabric at least partially or is avoided entirely. This task is accomplished through procedures with those in claims 1, 18, 23, 25, 26, 29, 30, 34 and 35 specified process steps solved.

Characterized in that in the method according to claim 1 two one other adjacent sheets of cloth along their each other swept alongside each other in the same plane be arranged and at least along the longitudinal edges one side of a fiber strip on the adjacent Edge areas of the cloth sheets placed and by means of a Adhesive application with these edge areas permanently ver is bound, at the same time becomes a permanent connection of the reached both cloth tracks. Because the fibers of the fiber strip are aligned largely parallel to each other, they nestle close together. With one through the desired power transmission ability of the fiber strip predetermined total cross-section of the fibers per unit length of the fiber strip has the envelope surrounding these fibers area a relatively small height. In any case, it is much less than that due to an overlap of the doubling occurring on both sheets of fabric. The same applies if the fibers are distributed over two fiber strips, one on each side of the cloth tracks is arranged. Then because of that on both sides possible power transmission even more cheaper.

Through configurations according to claims 2 to 10, the Method according to claim 1 to local conditions and / or to existing equipment be fitted, with the configurations according to claim 6  or 10 is added that the adjacent sheets of cloth directly at the longitudinal edges facing each other be connected to each other.

With an embodiment according to claim 20, the outside lying longitudinal edges of the fabric sheets by welding with the fibers of a fiber strip are reinforced, wherein in the claims 21 and 22 expedient process variants are specified.  

Characterized in that in the method according to claim 23 cloth webs used, at least in part from a thermo plastic are made, and in that the edge area facing the other sheet of cloth each of the both sheets of cloth due to heat and force is compressed and its thickness is reduced, the two edge areas can overlap each other be put together and either by gluing or are permanently connected to one another by welding, where again a total thickness at the connection point is achieved, which is much lower than in the conventional process.

Through an embodiment according to claim 24, the lead follows thickness to be measured at the point in question load-bearing tractive forces.

Characterized in that in the method according to claim 25 on the mutually facing longitudinal edge of the two adjacent to each other beard cloth sheets a part of the warp threads is removed and the exposed ends of the weft threads one above the other placed and permanently together with an adhesive a connection point is created, whose total thickness is less than that of the individual Cloth webs. The same is done with a method according to Claim 26 achieved in which the free ends of the shot threads are welded together. An arrangement of these two methods according to claim 27 improves the Power transmission capacity in that the free ends of the Weft threads of both cloth sheets at least partially with each other are swirled and thereby between the wefts of the a kind of positive connection is produced for both fabric sheets. By an embodiment according to claim 28 is also achieved a strengthening of the connection point, the Thickness of the joint itself does not exceed the thickness of the individual cloth webs increases and, as far as the fibers of the Fibers strips on the still provided with warp threads extend bar range, the thickness increases only slightly.

The in Fig. 1 and Fig. 2 in high magnification of cut as apparent cloth 30, which is used as an awning cloth or a conservatory awning, is formed by two fabric panels 31 and 32 which are joined along the facing longitudinal edges 33 and 34 together permanently . To facilitate the presentation and overview, the warp threads 35 are shown with an increased mutual distance and at the same height in both cloth webs 31 and 32 and the weft threads 36 are shown close to each other but more twisted, alternating with dotting for better distinction and are shown without dotting.

The cloth webs, which generally have a production width of 1.20 m, are cut to the web width required for the total width of the cloth 30 , the so-called repeat of a surface or stripe pattern being taken into account where appropriate.

The two cloth webs 31 and 32 are arranged side by side with the longitudinal edges 33 and 34 facing each other in the same plane. The longitudinal edges 33 and 34 can be butted close to one another, or a space 37 , albeit very small, can be left free between them.

The apparent from Fig. 1 and Fig. 2 execution for the connection of the two tissue webs 31 and 32 is mainly caused by two fiber strips 38 and 39 with each other largely parallel from a larger number of fibers 41 are formed. The fibers 41 are at least approximately aligned transversely to the longitudinal extension of the fiber strips 38 and 39 , which in turn are arranged parallel to the longitudinal edges 33 and 34 , and at least approximately centrally to the longitudinal edges 33 and 34 .

In order to be able to handle the fibers 41 more easily, in particular to be able to ensure their parallel alignment with one another, it is expedient that the fibers 41 are either stapled to one another and thereby themselves form a physically graspable fiber strip and / or that they are attached to a carrier film 42 from which they can be detached or, in other words, which can be peeled and removed from them. In the following, this type of fiber strip with fibers 41 attached to a carrier film 42 is always assumed.

The procedure for connecting the two fabric sheets 31 and 32 depends to a not inconsiderable extent on the local conditions, in particular on the technical equipment of the manufacturer of the awning fabric. Depending on these circumstances, the next process steps can be varied.

One of the process variants is to apply an adhesive material 45 on the edge area 43 or 44 of the two cloth webs 31 and 32 , which will later be covered by the fiber strips 38, which covers the edge areas 43 and 44 and, if possible, to the inside the cloth penetrates sheets 41 and 42 , so to speak soaks them through. The fibers 41 of the fiber strip 38 are placed and pressed onto the edge regions 43 and 44 with the adhesive 45 , so that after the adhesive 45 has solidified, the cloth webs 31 and 32 are first permanently connected to one another via the fibers 41 of the fiber strip 38 on one side .

After the adhesive application 45 has solidified, the cloth webs 31 and 32 are turned over. On the side of the edge areas 43 and 44 which is now at the top, a further adhesive application 46 is applied. Then the fiber strip 39 is placed so that its fibers 41 after the solidification of the adhesive 46 also the two cloth webs 31 and 32 permanently connect with each other.

When the two adhesive orders 45 and 46 are sufficiently solidified, the carrier film 42 of the fiber strips 38 and 39 is peeled off.

Another method variant is to first place one of the two fiber strips, for example the fiber strip 39 , on a base. The adhesive 46 is then applied to the fiber strip 39 . The two cloth webs 31 and 32 are placed with their edge region 43 and 44 on one half of the fiber strip 39 and pressed. The adhesive 45 is applied to the upper side of the edge regions 43 and 44 , advantageously with an excess, so that it soaks through the edge regions 43 and 44 . The fiber strip 38 is placed thereon and pressed on.

After the adhesive orders 46 and 45 have solidified, the two carrier foils 42 are removed.

Another variant of the method is that both fiber strips 38 and 39 are already provided with the relevant adhesive application 45 and 46 before they are applied to the edge areas 43 and 44 of the cloth webs 31 and 32 and pressed or the cloth webs are applied to it and be pressed.

In all process variants, care must be taken that the adhesive between the two cloth webs 31 and 32 and each of the fiber strips 38 and 39 connected to them is brought to such an extent, ie with a certain excess, that a between the cloth webs 31 and 32 existing space 37 is filled by him and thereby the sheets 31 and 32 are also directly connected to each other.

From Fig. 3 and Fig. 4 can be seen from an outside cloth web, such as the cloth web 32 , according to Fig. 1 and Fig. 2, the outer longitudinal edge 51 , which is provided instead of a conventional seam seam with an edge reinforcement 52 , which was created according to a procedure similar to those used when connecting the two fabric sheets 31 and 32 . Several process variants are also possible here.

Generally speaking, a fiber strip 54 with fibers 55 is placed around the edge region 53 of the fabric 32 and the fibers 55 are permanently connected to the edge region 53 by means of an adhesive 56 . The fiber strip 54 is practically identical to the fiber strips 38 and 39 ( FIG. 1). Its fibers 55 are largely parallel to each other and aligned transversely to the longitudinal extent of the fiber strip 54 . For easier handling, the fibers 55 are stapled to one another and also attached to a carrier film 57 , which is subsequently pulled off.

In one variant of the method, the fiber strip 54 with the carrier film 57 is placed on a base. The adhesive 56 is applied to the fiber strips. The cloth web 32 is applied with its edge region 53 to a partial region of the fiber strip 54 , which corresponds to almost half of its total width. The other portion of the fiber strip 54 is turned around the longitudinal edge 51 to the other side of the cloth web 32 and pressed against it. After the adhesive 56 has solidified, the fibers 55 of the fiber strip 54 are permanently connected to the edge region 53 of the cloth web 32 . The carrier film 57 can then be pulled off.

In another process variant, the adhesive 56 is attached to the edge portion 53 of the cloth web 32, the edge 53 as it were impregnated with the adhesive area 56th The adhesive 56 should be applied with a certain excess, so that not only the threads of the cloth web 32 are glued together, but also their bonding with the fibers 55 of the fiber strip 54 is guaranteed.

Another variant could be to first only provide the first part of the fiber strip 54 with a first part of the adhesive 56, to place and press the edge region 53 of the fabric web 32 onto this first part of the fiber strip 55 , the second part of the adhesive 56 to apply the top of the edge region 53 and then to fold the second portion of the fiber strip 54 around the longitudinal edge 51 and to put it on and press on the top of the edge region 53 .

This can be varied further such that before the edge region 53 is placed on the fiber strip 54, its second partial region is first folded up by an angle between 45 ° and 90 ° and only then is the adhesive 54 applied to the first partial region of the fiber strip 54 . This makes it easier both in the first and in the second application of adhesive to reliably soak the edge region 53 on its outer edge and even to bring a small excess of adhesive in the fold of the envelope.

Another variant of the previously explained method comes into consideration, not just before gluing the concerned parts to apply the adhesive fresh, so to speak but instead an activatable adhesive Use that before merging the parts the designated areas and locations and that was done after that at a later date Merging the parts into one that corresponds to its nature the way is activated, thereby filling the bond det. Above all, you can use this approach Fibers on which facilitate processing tion, the fibers conveniently stitched together are and possibly also attached to a carrier film are. If the adhesive used for stapling is sufficient dosed excess is applied, it can after the act four also the task of gluing the fibers of the fiber strip with the relevant section of cloth to take.

The pre-assembly of the adhesive application can also be made in that an activatable adhesive is used, which has a consistent form, which so z. B. is in tape or cord form and the on there, can be placed or inserted where it is after activation should take effect.  

Another variant of the method is that if the cloth webs and the fibers of the fiber strips at least at least partly, but as completely as possible, from one thermoplastic are made with one other parts to be connected without separate adhesive be brought together and then by heat effect and force are permanently linked become, d. H. are welded together. It is make sure that for other reasons the fibers the fiber strip suitably used stapling agent welding the fibers to each other and to the does not affect the relevant fabric web section but on the contrary, before being supported.

Also when welding the fiber strips to the cloth web sections, it can be useful at certain points, for example in the space between the longitudinal edges two adjacent sheets of cloth or in the fold of the envelope fiber serving as edge reinforcement on the outer longitudinal edge additionally strip a thermoplastic, e.g. B. to attach in tape or cord form.

In the area indicated in Fig. 5 to Fig. 8 the method of the cloth 60 (Fig. 6) of the two tissue webs 61 and 62. det gebil. The prerequisite here is that both sheets of cloth consist at least in part, if possible completely, of thermoplastic plastics.

In the case of the two cloth webs 61 and 62 , the edge section 63 or 64 serving to connect them, which adjoins the associated longitudinal edge 65 or 66 , is compressed to one side by the action of heat and force and compressed to a permanent thickness which is less than is the initial thickness of the fabric. This Dickenvermin change is indicated in Fig. 5, Fig. 6 and Fig. 8 for technical reasons by a reduction in the thickness of the warp and weft threads. In reality, there are spatial squeezing processes by which the material of the threads is pressed into the cavities that are always present as a result of the thread and fabric structure.

There are two possibilities for connecting the two fabric sheets 61 and 62 pretreated at their edge area 63 and 64, respectively. One is to bring an adhesive application in the plan area of the edge areas 63 and 64 , to apply and press the edge areas 63 and 64 in a complementary direction from their reduction in thickness, and thus to permanently connect the two fabric sheets 61 and 62 to one another. The other consists of placing the two edge regions 63 and 64 against one another in a complementary alignment of their thickness reduction and connecting them to one another by the action of heat and force, ie to weld them together. The previous targeted reduction in thickness prevented the occurrence of uncontrolled confused deformations in the edge areas, which could impair the strength of the fabric at the connection point.

Variants are also possible for this method, such as the one that a fiber strip 67 or 68 is placed on one side or on both sides of the cloth 60 ( FIG. 8), the fibers of which by means of an adhesive order 69 with the cloth 60 get connected. In another variant, the fibers of the fiber strips 67 and 68 are connected to the cloth 60 by the action of heat and force, ie welded to it. In both cases, it is expedient that fiber strips 67 and 68 are used which have a greater width than the edge regions 63 and 64 which are glued or welded to one another.

From Fig. 9 to Fig. 12, another method is ersicht Lich, with which a cloth 70 ( Fig. 11 and Fig. 12) is made from the cloth sheets 71 and 72 .

In the edge area 75 and 76 adjoining the longitudinal edge 73 and 74 , the warp threads 77 and 78 are removed, so that the ends of the weft threads 81 and 82 are exposed there. Because of the lack of the warp threads, the weft threads 81 and 82 are aligned largely parallel to one another in this area.

The two fabric sheets 71 and 72 are brought together in such a way that their edge areas 75 and 76 are located in the same plan area and the free ends of their warp threads 81 and 82 lie one above the other ( FIG. 11). The free ends of the weft threads 81 and 82 can be at least partially intermingled with an air jet, so that this alone produces a certain positive fit between the weft threads 81 and 82 of the two cloth webs 71 and 72 .

An adhesive application 79 is applied at least in the overlapping edge areas 75 and 76 of the two cloth webs 71 and 72 . It is expedient to extend this adhesive application 79 beyond the edge regions 75 and 76 to a certain extent also to the adjoining regions of the two cloth webs 71 and 72 .

A variant of this method is to connect the free ends of the warp threads 81 and 82 in the common edge region 75 , 76 by the action of heat and force, ie to weld them together, if at least the warp threads 81 and 82 are made of a thermoplastic material .

A further variant of this method consists in arranging a fiber strip 83 or 84 on one side or on both sides of the common edge region 75 , 76 and the fibers thereof either by means of an excess of the adhesive 79 or by means of an additional adhesive with the two cloth webs 71 and 72 to connect permanently ( Fig. 13). If both the weft threads 81 and 82 of the cloth webs 71 and 72 as well as the fibers of the fiber strips 83 and 84 consist of a thermoplastic material, the fiber strips 83 and 84 can also be welded to the cloth webs 71 and 72 .

In the method shown in FIG. 14, the cloth 90 is formed from the two cloth webs 91 and 92 . In both sheets 91 and 92 of the other sheet facing longitudinal edge is trimmed with a zigzag-shaped cut pattern 93 , which is complementary to each other in both sheets. The two cloth webs 91 and 92 are brought together in the same plane so that the cutting patterns fit closely together at their longitudinal edge. At least in the area of the floor plan of the pattern 93 , an adhesive application is applied and the two cloth webs 91 and 92 are connected to one another along the pattern 93 .

In the case of the cloth 90 , it is particularly expedient to attach a fiber strip 94 at least on one side, better on both sides, and to connect this permanently by means of an adhesive 95 with the cloth webs 91 and 92 on both sides of the pattern 93 , this adhesive material can also serve to connect the two cloth webs 91 and 92 themselves.

In the process shown in FIG. 15, in which the cloth 100 is formed by the two cloth webs 101 and 102 , the modification compared to the process according to FIG. 14 only consists in the pattern 103 , which has a meandering outline. This pattern 103 is expediently carried out in such a way that when the longitudinal edges of the two cloth webs 101 and 102 emerge before jumps 104 and 105, the head turned away from the cloth web 101 and 102 has a greater width than that of the neck facing the cloth web. As a result, a certain cohesion of their longitudinal edges is already achieved when the fabric webs are guided together.

Also with the cloth 100 , it is useful to arrange at least one fiber strip 106 at least on one side, but better on both sides of the cloth 100 and to glue or weld with the cloth webs 102 and 103 on both sides of the cutting line 103 .

In the method shown in FIG. 16, in which the cloth 110 is formed from the two cloth webs 111 and 112 , the two cloth webs 111 and 112 are joined along a meandering pattern 113 , as is the case with the cloth web 100 ( FIG. 15) Case is. Provided that the two cloth webs 111 and 112 are made of a thermoplastic material, the process for producing the cloth 110 is varied in such a way that the longitudinal edges of the two cloth webs 111 and 112 which abut one another along the meandering outline of the cutting pattern 113 by means of a weld seam 114 are connected to each other, the z. B. is generated by means of a laser beam oscillating normal to the outline of the cutting pattern 113 .

Also with the cloth 110 , it is expedient to strengthen the connection by means of fiber strips, even if these are not shown in FIG. 16.

In the method shown in FIG. 17, in which the fabric 120 is formed from the fabric sheets 121 and 122 , the two fabric sheets 121 and 122 rest against one another along their straight longitudinal edge 123 and 124, respectively. In the area of these longitudinal edges, the two sheets of cloth 121 and 122 are connected to one another by means of an adhesive application 125 . In addition to the adhesive application 125 , the two cloth webs 121 and 122 are also connected to one another by a zigzag seam 126 extending into the edge region of the two cloth webs. This zigzag seam 126 can have a triangular outline, as shown in FIG. 17. But it can also have a rectangular outline, as shown in the zigzag seam 136 in Fig. 18, which connects the two sheets 131 and 132 to the sheet 130 . There, too, the two cloth webs 131 and 132 are additionally connected to one another along the straight longitudinal edges 133 and 134 which are running ver by means of an adhesive 135 .

A variant of these two zigzag seams can also consist in the fact that it is designed with a trapezoidal outline and thereby combines, so to speak, the geometric basic elements of the zigzag seams 126 and 136 . Even in the case of the method in which two sheets of cloth are connected to one another, inter alia by means of a zigzag seam, it may be expedient to additionally attach one or two fiber strips in the region of the longitudinal edges.

In the in Fig. 19 and Fig. 20 apparent the process of the cloth 140 is formed from the two fabric panels 141 and 142. They abut each other along the straight longitudinal edges 143 and 144 . There they are connected to each other by means of an adhesive order 145 .

In a border area 146 and 147 adjoining the respective longitudinal edge, the cohesion of the threads of the fabric webs 141 and 142 , ie both their warp threads 148 and their weft threads 149 , is reinforced either by applying an adhesive 151 or 152 or by the Warp and weft threads are at least partially welded together under the influence of heat and force.

In the plan area of the two reinforced edge regions 146 and 147 , a number of staples 153 are placed next to one another with a certain mutual spacing, which are aligned parallel to one another, at least approximately centrally to the longitudinal edges 143 and 144 . The staples 153 are made of a corrosion-resistant material.
