The invention also relates to a method for producing a duvet with the following steps:

a) providing an outer fabric, an underlay and a filling;

b) arranging the filling between the outer fabric and the lower fabric;

c) disposing a circumferential terminating strand along the array of step b) about which a band is beaten;

d) bonding the tape to the upper and lower fabric.

A duvet and a manufacturing method of this kind are generally known in the art (see, e.g., U.S. Patent No. 2,217,621).

For duvets comes the design of the surrounding edge, along which the outer fabric and the lower fabric are sewn together are, of particular importance too. For one thing, the edge must be in terms of functional properties, e.g. Strength and durability the connection, meet certain requirements. On the other hand, the edge also fulfills an aesthetic Function, since qualitative defects, such as inadequacies in processing or material selection, in this area the blanket especially eye-catching. The one taken in the band End strand, usually in the form of a cord, ensures a visually appealing and even appearing circumferential Edge.

A blanket of the type mentioned is shown in Fig. 6a in a Top view and in Fig. 6b in a side enlarged Section along the line VIb-VIb shown very schematically. The blanket 60, on the outer fabric 61, a seam 62nd is implied on its edge with a pebbly border provided, consisting of a running along the edge Kordel 63 and a band 64 consists. The long sides of the band 64 are wrapped around the cord 63, so that the band 64 the cord 63 completely enveloped. The directly on each other lying ends 65 of the longitudinal sides of the belt 64 are between inwardly wrapped edges of the outer fabric 61 and a Unterstoffs 66 arranged. With the help of a dashed line indicated Seam 67 is the band 64 with the outer fabric 61 and the lower fabric 66 connected. A filling 68 of the blanket 60, at which is e.g. to be able to act down is between the outer fabric 61 and the lower fabric 66 distributed.

This pebbly edge design is aesthetically pleasing and conveys a pleasant because of the bordered cord 63 handy feeling. In addition, with this border design Make comforters with sharp corners. pleats the band 64 at its inner edge in the corner area, the due to the compression of the belt 64 when passing around the Corner are unavoidable, are made of the outer fabric 61 and lower fabric 66 covered. Thus, these wrinkles are not apparent and the uniform appearance is taken from the Cord intended.

The disadvantage, however, that in this known edge design the filling 68 for manufacturing reasons not is fixed at the edge. To fix the filling between the band edges placed around the terminating strand are brought and this assembly then between the cut edges of outer fabric and lower fabric are placed. When fixing by This assembly would be stitched out of seven superimposed ones Layers inevitably slip. It would be difficult or even impossible, when sewing a longitudinal edge of a 2 m long blanket this assembly later, e.g. to Sewing a particular route in particular the seat of the innermost Able to correct, namely the filling. Fillings 68, which are not attached along the edge of a duvet, however, tend to do so during use or during washing to slip inside the blanket. It can then become unwanted Build up accumulations of filling in some areas, while in other areas the filling is wholly or partly is missing.

A well-known duvet with a fixation of the filling is in Fig. 7a in a plan view and in Fig. 7b in a lateral enlarged section along the line VIIb-VIIb simplified shown.

In this known blanket 70, the edges of an outer fabric 72 and an under fabric 74 bordered by a band 76, the much wider than that in the tench-like edge design 6 and 6b is band 64. Thereby it is possible to have a circumferential end portion of the filling 79 between the embraced edges of outer fabric 72nd and lower fabric 74 and these areas from the outside through to beat the broad band. The long sides of the band 76 are immediate, i. without an additional cord, outside around the edges of the outer fabric 72 and the lower fabric 74 are turned around and sewed with these and the filling via a seam 78. Slippage of the filling 79 in the marginal chambers of Duvet 70 is prevented.

This band edging conveys a relatively broad lobed Edge.

A further disadvantage is that the above-mentioned pleats, the inevitably when driving around the belt 76 to corners at the inside edge, not at the band edge are covered by the outer fabric 72 and lower fabric 74. To the pleating to hold in visually acceptable limits, the corners become the blanket 70 rounded with a relatively large radius of curvature executed, as can be seen in Fig. 7a. Round corners However, they are undesirable because the covers of comforters in usually have sharp corners and thus there from the comforters only partially completed.

A similar tape enclosure is also known from DE 198 21 047 A1 known. In contrast to the band enclosure described above However, there are the longitudinal edges of the tape in front of the Sew with the filling and the upper and lower fabric inside turned over, causing fraying of the longitudinal edges of the Bandes is prevented.

From DE 43 32 863 C1 is a particular as a duvet cover intended fabric shell known, the "stitched on the left" and only everted after completion of all sewing. The edge the fabric cover described there is provided with a piping, however, the seam with which the tuck on the outer fabric and the lower fabric is attached, due to the subsequent Everting from the outside is not recognizable. The tucks will be not sewn in one go around corners of the fabric cover, but instead overlap in the area of the rounded executed Corners partly.

It is an object of the present invention to provide a duvet of specify the type mentioned above, on the one hand slipping prevents the filling from the edge of the bedspread, and on the other hand aesthetically pleasing and nevertheless production technology is inexpensive to produce.

It is also an object of the present invention to provide a simple feasible method for producing such a duvet specify.

With regard to the blanket, this object is achieved by that the long sides of the tape on the outside of the blanket rest on the forming sides of the outer fabric and the lower fabric and also associated with the filling.

With regard to the method, this object is achieved by that the long sides of the tape on the outside of the blanket forming sides of the outer fabric and the lower fabric and also attached to the filling.

The fact that the tape from the outside on the outer fabric and the bottom fabric is sewn on, the filling can immediately until reach the edge of the blanket and, together with the band, sewn to the outer fabric and the lower fabric and thus fixed. Slipping of the filling is thus excluded. Also in comforters whose interior is in cassettes or longitudinal channels is divided, attached to the boundaries of the filling is a fixation of the filling along the edge of the Duvet advantageous. That's because the channels have that way or cassettes along the longitudinal edges the same filling properties like those that are arranged inside the ceiling are.

In particular, the attachment of the tape from the outside under manufacturing technology Considerably simpler than that Longitudinal sides of the band between the outer fabric and the lower fabric to align, as in the well-known biesenartigen Edge design is the case.

The assembly of lower fabric, filling and outer fabric can be aligned, if necessary by cutting the edges exactly on aligned position of the outer edges are brought. It is production engineering easy, now the over the termination strand beaten protruding edges to the outside of the bottom fabric and outer fabric and to assemble by sewing fix. This is possible with very narrow bands, so that the visually appealing conclusion with the narrow edge remains.

It has also been found that by using very Narrow bands also an attractive design of the corners achievable is, with only a very slight pleating of the band occurs. It is even possible to form almost rectangular corners, being only in the corner a single pleating of the band takes place, but optically suppressed by the terminating strand becomes. In addition, the attachment of the tape opens from the outside several other possibilities, an aesthetically pleasing design also to achieve very sharp corners, where on will be discussed in more detail below.

The solution according to the invention thus combines in a surprising manner the advantages of the pompous enclosure with those of Edging.

The object of the invention is completely solved in this way.

Although duvets are generally rectangular, the invention is but also in circular, octagonal, or other Way shaped comforters are advantageously applicable.

The term substance is also to be understood in the broadest sense and includes all types of planar structures that are woven or nonwoven, natural or natural synthetic materials. As a final strand is suitable, for example a fabric cord, but also a cord of one other material that has the desired flexibility and strength having. The termination strand can also consist of a string, are mounted on the small balls or rollers.

The filling can be any kind of heat-insulating material act, e.g. Down, cotton-like continuous filaments, Mixtures of several materials or tile-like fabrics.

For fastening the band with the outer fabric, the under material and the filling is mainly a seam into consideration. Conceivable However, other fasteners, such as a variety small rivet-like pins, which are characterized by the materials mentioned let it pierce by machine.

The band can be in the strict geometric sense of the form of a have elongated rectangles. Usable for the invention certainly also a band that is only approximately rectangular and For example, has corrugated longitudinal edges. As material come in addition to substances of all kinds and colored plastic films or similar into consideration.

In a preferred embodiment of the invention, the Long sides of the band reinforced by turning inside.

This measure has the advantage that fraying the band edge in ligaments of tissue that can fray effectively is prevented.

One way to create an aesthetically pleasing design To achieve corner areas, there are several terminations and to provide them with enclosing bands, each longitudinally extend an edge between two corners and about on impact end up. It can then in the corner another short band on attached to the underlying ribbons, which are the ends the underlying bands and terminations covered and thus to an appealing appearance of the corner area leads. If the terminating strand is not led around the corner, even sharper corners can be realized than this in the known biesen-like edge design is the case. This is especially true when a final strand as a comparative solid material, such as a tightly twisted fabric cord, is used.

In a particularly preferred embodiment of the invention However, to achieve sharp corners provided that one end of the band is approximately flush with the corner, and that one End portion of a second band, extending along the other Randes extends, so turned around this corner and in this Position is fixed, that the end portion of the second band the Covered at the end of the other band.

This measure has the advantage over the aforementioned variant, that no additional band is to be provided, which at producing precisely over two underlying bands must be aligned. Rather, it will be easy to manufacture a protruding end portion of the one band seized, knocked around the corner and fastened on the other band. Turning around a sharp corner forms only in the corner area on the two long sides of the upper band only one fold each, the appealing appearance the edge design is not affected.

The second volume does not have to have its own final string either enclose. This is e.g. then conceivable, if a page the blanket is provided with a zipper and therefore should be designed differently.

Preferably, however, the second band is a second terminating strand knocked over, which ends at the corner. The ends the final strands are about on impact, but by the protruding and turned over end portion of the second band covered.

This measure has the advantage that a very uniform appearance the edge design is achieved.

In a preferred embodiment of this embodiment provided that the blanket is rectangular, that along the Transverse sides and the longitudinal sides of the cover each a ribbon and a strand enclosed therein runs, and that the End portions of the bands along the transverse sides each around the Corners are turned over and the ends of the ribbons along the Cover longitudinal sides.

This measure has the advantage that the edge designs of Long sides can be done with the help of a machine. On the shorter transverse sides of the prepared blanket then become with the help of a sewing machine the final strands and they sewn on bordering bands. Subsequently, the supernumerary End portions of the transverse bands at the corners turned over and on the respective underlying longitudinal side Band attached.

It is understood that the above and the following yet to be explained features not only in the specified Combinations, but also in other combinations or can be attached in isolation, without the scope of the present To leave invention.

1 and 2 is a blanket according to the invention with 10th designated.

The blanket 10 has an outer fabric 12 and a lower fabric 14 on. Between outer fabric 12 and lower fabric 14 is a filling 18 received in the form of continuous fibers.

On the outer fabric 12 is by transverse or longitudinal seams 20 a Subdivision of the ceiling in several chambers 22 indicated by the large-scale slippage of the filling 18 in the Bettdekke 10 is prevented. Such a subdivision is in particular for slightly movable fillings, such as down, expedient; when using continuous fibers or tile-like fillings, which are less prone to slipping by themselves Such Einteilungsnähte 20 alone aesthetic Be provided for reasons. For the invention is such Classification, however, not essential.

Fig. 3 shows the detail III of Fig. 2 in an enlarged Presentation. In this illustration it can be seen that the filling 18 within the blanket 10 approximately to the outer edge 16 of the outer fabric 12 and the outer edge 17 of the lower fabric 14 extends. Over the respective outer edge of Outer fabric 12 and lower fabric is a folded band 26 laid that also around a fabric cord End strand 24 is beaten. The longitudinal ends 28 of the band 26 are beaten inwards and are on the Outside of the duvet forming sides of the outer fabric 12 and of the lower fabric 14. In this position are the long-side Ends 28 of the belt 26 on the outer fabric 12, the lower fabric 14th and the filling 18 by one over the entire vertical Extension extending seam 30 attached.

The width b of the edge region is in the illustrated embodiment about 7 mm. The total width of the band 26 before the Turning over the long ends is 30 mm.

For completeness, it should be noted that the interstices, in the arrangement shown in Fig. 3 between the individual parts mentioned, only for reasons the clarity are shown; lie in reality the individual parts directly on each other.

FIG. 4 shows a representation corresponding to FIG. 3 Another embodiment of the edge design according to the invention. The filling is a one Tissue-like tissue 32, whose thickness is approximately equal to the diameter of the final strand 24 corresponds.

The following is an advantageous method of manufacture the blanket according to the invention with reference to FIGS. 5.1 to 5.8 explained.

Fig. 5.1a shows in a plan view and in a section along the line V.Ib-V.Ib a first stage of the later duvet, in which a sub-fabric 14, a filling 18 and an outer fabric 12 are stacked on top of each other. The outer edge 16 of the Outer fabric 12 and the outer edge 17 of the lower fabric 14 are thereby, as seen in the sectional view of Fig. 5.1b is aligned over each other. The filling 18 is enough also to the formed by the outer edges 16, 17 Edge approach. In the following, it is assumed that the Filling 18 is a tiled tissue that is in a Cutting process together with the outer fabric 12 and the lower fabric 14 in the desired, shown in Fig. 5.1a rectangular shape was brought.

In a second step will now be machined along the long sides the stacked rectangular layers each a longitudinal end strand 34, 36 created. The final strands 34, 36 are located immediately before Outside edges 16, 17 of the outer fabric 12 and the lower fabric 14th In each case project end portions of the terminating strands 34, 36 beyond the transverse sides. This state is shown in FIGS. 5.2a and 5.2b shown. Alternatively, of course, it is also possible the final strands 34, 36 before cutting the Outer fabric 12, the bottom fabric 14 and the lint-like fabric 18 and then cut together in the same cutting process.

In a further step, the final strands 34, 36 each have a band 38, 40 in the above to Fig. 3 described Worn way and in this position on the outward facing Sutured sides of the outer fabric 12 and the bottom fabric 14. The longitudinal sides of the blanket thus already have, as shown in FIG. 5.3b can be seen, the explained in Fig. 3 shape.

In a following step will possibly still on the transverse sides cut off projecting end sections. The condition after the cutting is shown in Fig. 5.4.

After cutting to length along the transverse sides also terminations 42, 44 (FIG. 5.5) and with transverse sides Bands 46, 48 on the outer fabric 12, the lower fabric 14 and the Fastener 18 attached (Figure 5.6). The termination rods 42, 44 are also cut to length, while in the bands 46, 48 about the corner projecting end portions 50a, 50b, 50c and 50d remain.

Thereafter, these projecting end portions 50a, 50b, 50c and 50d in the direction indicated by arrows 52a, 52b, 52c and 52d Turned around the corners (Fig. 5.7), so that the folded end portions 50a, 50b, 50c and 50d of transverse side bands 46, 48 the ends of the longitudinal bands Cover each 38, 40 each.

In this final state, shown in Fig. 5.8a, the turned end portions 50a, 50b, 50c and 50d with the underneath Sewn layers lying. As shown in Fig. 5.8b Section along the line V.VIIIb-V.VIIIb recognizable is in this state, the folded end portion 50b of the tape 48 over the tape 40. The same applies accordingly for the other folded end portions 50a, 50c and 50d.
