Description

Elastically resilient and preferably resilient fillers Containing Spatially Profiled Web The present invention relates to elastic resilient and preferably resilient, fillers-containing, a structure made of single layers, smooth, non-slip, dry-cleanable and spatially profiled track for covering or covering sleeping, travel, couchette, Bedspreads, pillows, sitting, leaning, solid walls, room ceilings, power-Iährzeug side parts, Doors, mattresses, room decorations, items of clothing or the like .. Come as blankets especially quilts with paser or capricious or feather fillings, bedspreads Consider pillows with washable synthetic fiber fillers. Other products of the The bedding industry is sod mattress toppers, reform under-beds and quilted quilts and duvet covers of all kinds. The seats are in particular motor vehicle seats, Backrests, side rests, interior door panels and side panel panels on the back seats of a motor vehicle. In the technology of upholstered furniture consider the side and back of armchairs, Couohecß Se8bel - Seat cushions, Chouch - seat cushions, armchairs and Cheuch - back cushions, Ohouch seat covers, that are made of one piece, Ohouch backs that are made of one piece, Profiled upholstered furniture backs. Regarding the mattress Industry are to be mentioned mattress cover plates in predominantly one-piece execution with the well-known ornaments made by stitching. In terms of furniture technology and room decoration include partial cladding of furniture, wall and ceiling surfaces. In clothing technology, dressing gowns are provided with fillings, anoraks and Sleeping bags. However, this is not an exhaustive list of the registration options.

So far, such tracks, including by department The individual pieces that have come about are understood, the necessary profile patterning by hand obtained, in which preferably so-called quilting seams are made. Through the Quilting seams pull the fillers together, and there are dependencies from the arrangement and position of the quilting seams required patterns and ornaments, especially in the form of squares, rectangles and rhombuses, if not different Patterns are to be realized.

The present invention is set to the task of this manual work in To bring omission.

This task is solved when the profiling areas of the web High frequency welds are. So it only needs to be carried out High-frequency training with appropriately arranged electrodes in order to ornamental patterns by means of a single work process with practical elimination to be able to produce by hand.

To wash items made from such webs and chemically To be able to clean, exist the welding mediators occurring in the weld seams expediently made of polyamides, especially modified polyamides. As such are Examples of these are polycondensation products from hexamethylenediamine and adipic acid. The synthetic resin can also be a polyamide of aminocaproic acid.

Polyamides of the 7-aminic acid, the 9 - Amino - nonanoic acid, the ii - amino - undecanoic acid. The sweat-promoting synthetic resin can also be a polyamide based on dodecanolactam. However, one is not only dependent on polyamides and modified polyamides.

Polyethylene and especially polypropylene can also be used.

It is advantageous if the carrier is in the form of synthetic resin particles occurring welding agent a single layer of the synthetic resin particles carrying Web occurs with the particles either attached to or incorporated into the web are. The methods used for this purpose are known per se and do not require any representation. If such individual tracks are used as a carrier of the welding agent, so come in particular from cellulose, from foam, from fiber fleece and the newly developed spun-bond fabrics are considered. It is irrelevant whether the individual layers are only consist of one or more layers. It can also come from different Existing layers of materials form a single layer insofar as the particles are incorporated into or into this single layer, with the particles preferably in the contact surfaces made of different materials existing layers can occur.

Also the machines for carrying out procedures to apply the particles with mutual distances and the same layer thickness are per se are known and therefore do not require any representation.

The drawing shows exemplary embodiments in a highly schematic representation a web designed according to the invention again.

Fig. 1 shows an embodiment of the web in which the welding agent load-bearing single layer occurs approximately in the median plane of the web, while Pig. 2 a Exemplary embodiment illustrates in which the welding agent carrying Single layer delimits the web as an outer layer.

The last-mentioned web is not suitable for further processing only for welding purposes, but also for ice sealing, since the synthetic resin particles load-bearing single layer can be brought into the state that a lIeiss seal for the purpose of connection with other fabrics or webs.

In Fig. 1 an enlarged section through the web is schematically made clear. Hit 1 and 2 are upper and lower cover fabrics indicated, between which fillings 3 are utid 4, which are designed as fleeces.

All fibrous materials are used as materials for such fillings Consider whose properties enable them to act as fillings. To call are in particular the natural and man-made fibers, among the natural fiber materials the vegetable and animal fibers, those made of man-made fibers natural and synthetic raw materials. Finally, there is a welding agent load-bearing middle layer 5. As sweat mediators are made of polyamides Synthetic resin body 51 indicated chemically. Next, the middle single ply is 5 in Sections 52, 53, 54 etc. have been split up to indicate that, for example, as shown at 52 as the carrier of the synthetic resin particles 51 a foam layer can be provided, the material for the foam in particular plastic foams, such as polyurethane, come into consideration.

The number 53 indicates that a single or multi-layer Fibrous web can be used to form the middle layer 5, wherein embedded synthetic resin particles have been designated with 55. Section 54 is intended illustrate that as a carrier of the synthetic resin particles consisting of modified polyamides 56 pulp can also be considered. Another possibility is to use it of the so-called spun-bond material, not shown in the drawing, as in general any material comes into consideration that is capable of being deposited or embedded incorporated, suitably designed synthetic resin in the form of synthetic resin powder and get in its position.

Finally, at 71, 72 etc. the spatial profile is indicated, which arises from the fact that high-frequency electrodes are attached to these points have been. However, the deformation of the perspiration-promoting layer is not layer 5 has been clarified to show the appearance of the various materials Sections not to disturb. But of course that extends through that High-frequency welds 71, 72, etc. resulting, spatial profiles in the welding layer layer 5 into it, so that the synthetic resin particle 51, 55, 56 etc. the entire bundle of layers 1, 3, 5, 4, 2 is recorded. By the same time Any welding of the layers at the points 71, 72 occurs in three dimensions ProfilXierung, which before the present invention could only be achieved by quilted seams, in particular in the form of decorative quilted seams, are attached at these points became.

The role of the sewing threads is now through the synthetic resin particles 51, 55, 56 etc. and the arrangement and formation of the self are formed High-frequency electrodes (not shown) correspondingly designed, spatial Profiles, with the fillings 3 and 4 outside of the welds Maintaining the original shape and thus acting elastically and resiliently Form cushions, which are indicated at 81, 82, 83.

The same high frequency welding can be used to make the web 6 to complete at 9 and the fillings 3 and 4 lying there as well as the sweat-promoting To close middle layer 5 to form a uniform, compressed seam.

Naturally, edging tapes or other, known measures can be provided to a portion of the web 6, for example to form a quilt is used to give a good taste appearance.

In the embodiment according to FIG. 2, the weld-imparting limit Layer layer 1o the web 6 on one side. It will therefore be on the opposite side limited only by the upper cover fabric 1.

Towards the sweat-promoting layer lo, it is excluded Foam consisting of a further layer of fabric and a filling 12 made of nonwovens at.

The sweat-promoting outer layer 1o can again accordingly the representation of the section 13 made of foam, according to the representation of the section 14 made of a nonwoven fabric, as shown in the illustration of the section 15 made of cellulose or, not shown, of a spun-bond material, whereby it is of course also possible instead of the following in the longitudinal direction of the web Sections that are for purposes of illustration in this direction one another follow, the sweat-promoting layer 1o in the direction perpendicular thereto from individual layers to build, the materials correspond to the materials according to 13, 14, 15 etc. As well as the sweat-promoting layer layer lo is always either synthetic resin particles 16 attached or stored, so that in relation to the creation of a spatial profile, which is no longer shown in Fig. 2, the conditions prevail under which according to the representation of FIG. 1, the web is able to appear as a profiled body.

It is in the essence of the invention that the embodiments In no way exhaust the available options.

The invention also extends to some of those described above Features and ultimately it has their overall combination as well as all partial combinations the characteristics of the object, insofar as the latter is technically sensible and feasible as well They can be searched, even if the new technical effects that can be achieved in each case are mentioned above are not mentioned and described in detail. Likewise, all in the Details shown in the drawing as such and in their functional context assumed as described.
