Definitions
- the invention relates to a method for producing a loop seam intended for trimming and connecting textile pieces using a thread-like connecting element.
- Trimming also known as edge trimming, is a process that finishes a piece of fabric at the edges in such a way that the material cannot fray.
- edge trimming is a process that finishes a piece of fabric at the edges in such a way that the material cannot fray.
- overlock or “coverlock” seam is usually used, also called a “chain seam” or “zigzag stitch”, which uses sewing machines that usually process more than three threads at the same time.
- Another option for hemming edges is to neaten and secure the edge using the so-called folding and/or folding method. To do this, fold the edge of the fabric inwards once, then again if necessary and then through A seam is fixed, the previously open edge of the fabric is then on the inside and can no longer fray.
- a further disadvantage in the prior art has been shown to be the problem usually known as sewing foot height, that every sewing machine has a certain amount of clearance in the height under the sewing foot (device that is attached around the needle and presses the material down and together around it to facilitate the process). This means that above a certain height the sewing process is prevented because the machine cannot grasp and transport the fabric. This problem occurs particularly when processing leather and producing clothing from very thick and numerous layers of material.
- the object of the invention is to provide a novel method for trimming and connecting textile pieces, which enables easier processing, less waste and thus reduced environmental problems and, moreover, the production also provides completely different material combinations from clothing.
- the production of textile pieces from numerous fabric layers in the area of trouser hems and collars should also be carried out without any problems and corresponding materials such as foil and rubber should be able to be processed.
- Optimal solutions can be chosen for perforating the material, as this process step is independent of the further work required to produce the loop seam.
- edge trimming described above is significantly simplified by the novel method for producing a loop seam.
- the respective edge can be made with just one strip, strand of thread or bundle while sewing several layers of fabric at the same time.
- Edge finishing in the current industry usually requires one or more separate work steps or requires machines that require at least two different threads to produce a seam.
- these machines cannot perform the hemming and seaming step for all materials in one operation.
- the usual process known from the prior art is to first neaten the edges of the materials to be processed using an overlock machine and then to connect the materials together in a further step using a conventional sewing machine. Several different machines are therefore used, which naturally cause corresponding energy consumption and are seen as problematic in terms of costs and the environment.
- the loop seam according to the invention is particularly interesting here because it can be made entirely and exclusively by hand, which makes a fashion company conceivable without machines and without CO2 emissions.
- the versatility and quick implementation make the seam particularly competitive and the hand-made loop seam is visually very striking, which can represent an ideal aesthetic trademark and recognition feature.
- it can be applied by hand in places, even in very expressive - and extreme - forms, that a machine may not be able to adequately implement.
- Figure 3 is a perspective schematic representation of the second process step for producing the loop seam
- Figure 4 is a perspective schematic representation of what follows after the second process step
- 5A shows a perspective schematic representation of a first embodiment variant following the process step from FIG. 4
- 5B shows a perspective schematic representation of a second embodiment variant following the process step from FIG. 4,
- Figure 7 is a perspective schematic representation of the last process step following that of Figure 6 and
- Figure 8 is a perspective schematic representation of a connection between two pieces of textile using the loop seam according to the invention.
- this loop 4 can be arranged untwisted in an embodiment A as shown in FIG. 2 or as a loop with a single or multiple twist (not shown) according to the embodiment B.
- the loop 5 is guided from the rear plane of the textile piece 1 back to the front, so that it is possible to pull the front end of the loop 5 through the further recess lying next to the one recess 2 .
- FIG. 7 shows the final process step of pulling the free end of the loop 5 through the further recess 2. This results in the same starting position for the loop 5 as already shown in Figure 1.
- the process step sequence as shown in Figures 2 to 8, can now begin from.
- a series of individual loops are thus formed, which, viewed as a whole over the course of the edge region of the textile piece 1, form the loop seam according to the invention.
- the edge of the textile piece 1 is bordered, so that a trimming results, which provides reliable protection against fraying of the edge of the textile piece 1.
- the loop 5 is simultaneously marked as a loop 4 NEW.
- FIG. 8 finally illustrates how two pieces of textile 1, each of which is provided with a loop seam according to the invention on its adjacent edge regions, can be coupled to one another by means of a thread-like connecting band 6.
- the connecting band 6 is alternately passed through the adjacent loops 4 and 5 in the loop band. The result is a shoelace-like coupling of the loop seams and after tightening the connecting band 6 and the connecting elements 3 belonging to the two loop seams form a connecting seam of the two textile pieces 1 to be coupled.
- connection technology described as well as the production of the loop seam according to the invention, are shown in Figures 1-8, each with thread-like connecting elements 3 or connecting tape 6.
- thread-like connecting elements 3 or connecting tape 6 One does not move away from the scope of protection of the invention if, if necessary, these are made from wider strips of material by using recycled fabric strips as connecting elements 3 or as connecting tape 6. By using such fabric strips, a special, visually interesting additional effect can be achieved for design purposes, as has already been done in the description.
