Description

TECHNICAL AREA

The invention relates to a method of manufacturing a carpet whose external appearance comprises raised areas and lowered areas.

STATE OF THE ART

Carpets whose outer appearance includes raised areas and lowered areas, or carpets with perceptible relief, are known from the state of the art.

For example, the document US 2,860,669 discloses a high and low pile fabric comprising a base with warp yarns woven with filling yarns, pile yarns extending substantially in a woven manner with the base in the form of loops which vary in height according to the chain and wherein the curve of each loop extends over and above at least one of said warp yarns.

The document US 2,860,669 presents the problem that a relief is created using loops of variable height. In this case, it is not easy to obtain a uniform height of the loops in a given section of the fabric. In addition, the loops, and especially the loops higher, can remain attached to external objects that come into contact with such a fabric. There is thus a high risk of damaging the loops and hence the fabric. The document CN 203 960 473 U discloses a chenille fabric with the features set forth in the preamble of claim 1. The present invention has the objective of finding a solution to overcome at least some of the aforementioned problems.

In a preferred embodiment, the present invention provides a carpet according to the first aspect of the invention, wherein one or more weft yarns are caterpillar yarns, mainly as those used in high relief areas. This offers the advantage that the visual impression of the high relief effect is enhanced.
The use of chenille yarns as weft yarns has several advantages. The caterpillar son makes it possible to reinforce the visual impression of the high relief effect without being obliged to increase the quantity of weft threads used. The chenille yarn also has more volume than weight, thus making it possible to obtain a relatively light carpet despite the presence of the reliefs. The chenille yarn also provides the carpet with flexibility and reduces its rigidity thereby allowing a better folding of the carpet to improve the storage and / or transportation of the carpet.

In a preferred embodiment, the present invention provides a carpet according to the first aspect of the invention, wherein an anti-skid layer is attached to the side of the carpet which, during normal use, rests on a surface, such as only a floor. The anti-skid layer is intended to prevent slippage of the carpet relative to a surface, such as a floor. The anti-skid layer may comprise a latex-based material, a plastic-based material, such as PVC, or a rubber-based material. Fixing said anti-skid layer on said carpet side can be carried out by any suitable fastening method which is known from the state of the art.

In a preferred embodiment, the present invention provides a carpet according to the first aspect of the invention, wherein the carpet dimension is perpendicular to both the warp direction and the weft direction for a carpet section. following said second insertion pattern is at most 95% of said dimension for a section of the carpet following said first insertion pattern. In a preferred embodiment, said dimension for a section of the carpet following said second insertion pattern is at most 90% of said dimension for a section of the carpet following said first insertion pattern, and in a still preferred embodiment , said dimension for a section of the carpet following said second insertion pattern is at most 85% of said dimension for a section of the carpet following said first insertion pattern. In this way, the carpet has an outward appearance of raised and lowered sections, which can be clearly seen.

In a second aspect, the present invention provides a method of making a carpet with one or more raised areas, into which is inserted and woven a series of weft yarns substantially perpendicularly in a series of warp yarns according to one or more pre-determined insertion patterns, in which one or more zones are formed by means of substantially upper and lower floating yarns, thereby forming respectively a high relief or a low relief.

• la juxtaposition des fils de chaîne dans une lame sans qu'ils se chevauchent mutuellement; et
• l'insertion et le tissage desdits fils de trame le long desdits fils de chaîne, de telle manière que les fils de trame se trouvent dans des rangées successives et essentiellement perpendiculaires auxdits fils de chaîne, dans lequel les fils de trame sont insérés de façon répétée le long d'un ou de plusieurs fils de chaîne suivant des motifs d'insertion fixés au préalable, ce qui permet d'obtenir des fils de trame flottants,

dans lequel au moins un premier et un deuxième motifs d'insertion alternent, dans lequel la longueur moyenne des fils de trame flottants obtenus suivant le premier motif d'insertion est plus grande que la longueur moyenne des fils de trame flottants obtenus suivant le deuxième motif d'insertion.In a preferred embodiment, the present invention provides a method according to the second aspect of the invention, wherein a zone is inserted with substantially higher or lower floating yarns connecting to a zone with substantially lower or higher floating yarns. respectively. A visually enhanced relief effect is thus obtained by contrast with a neighboring zone having an opposite relief.
In a preferred embodiment, the present invention provides a method according to the second aspect of the invention, wherein one or more chenille yarns are inserted as weft yarns. This offers the advantage that the visual impression of the high relief effect is enhanced.
According to another specification of the method, the method comprises the following steps:

• the juxtaposition of the warp threads in a blade without overlapping each other; and
• inserting and weaving said weft yarns along said warp yarns, such that the weft yarns are in successive rows and substantially perpendicular to said warp yarns, wherein the weft yarns are repeatedly inserted along one or more warp threads according to pre-fixed insertion patterns, thereby obtaining floating weft threads,

wherein at least a first and a second insertion pattern alternate, wherein the average length of the floating weft yarns obtained according to the first insertion pattern is greater than the average length of the floating weft yarns obtained according to the second pattern. insertion.

By the juxtaposed insertion of warp threads into a blade without overlapping each other, support is formed for the weft threads and thus for the carpet. The warp threads are preferably tensioned between the warp beam of a blade known to those skilled in the art. The successive rows of the weft yarns can be placed one above the other when the blade and the warp yarns are placed upright with respect to a standing person. The rows of weft yarns will be placed next to each other when the blade and the warp yarns are placed in a supine position with respect to a standing person.

In a preferred embodiment, the warp yarns are placed in at least two planes parallel to each other. In each plane, the warp threads are placed without overlapping each other. The two planes form a support for the weft threads and therefore for the carpet.

In a preferred embodiment, the weft yarns are introduced and woven on the warp yarns while they are above or below the warp yarns of a first number of juxtaposed warp yarns and they are then below or above a second number of juxtaposed warp yarns, which are placed directly next to the first number of juxtaposed warp yarns. In some embodiments, the weft yarns are then above or below the warp yarns of a third number of juxtaposed warp yarns that lie directly next to the second number of juxtaposed warp yarns, and thus right now. The repeated passage of weft yarns below and above the warp yarns while the first number, the second number and the following numbers of warp yarns are kept constant, forms a row of an insertion pattern. An insertion pattern according to the present invention comprises several of these rows. In some embodiments, an insertion pattern includes only identical rows. In other embodiments, an insertion pattern includes different rows. In each row of the insertion pattern, said first, second, and subsequent numbers of warp threads are equal to or different from each other. The first number, the second number, or the number of each of the following numbers of warp threads can be 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 threads.

The number of warp threads determines the width, length or diameter of the carpet. The first warp thread takes the first position by going from the right to the left or from the left to the right of the support formed by the warp threads. The weft yarns are introduced and woven on the warp yarns in rows, so that a row starts at the height of a first warp yarn and extends to a last warp yarn, namely the one that is located farthest from the first warp. The insertion is performed in one direction and / or in the opposite direction: from right to left and / or from left to right along the support formed by the warp threads.

The second aspect of the invention is further characterized in that at least first and second insertion patterns are formed alternately, the average length of the floating weft yarns obtained according to the first insertion pattern being greater than than the average length of the floating weft yarns obtained according to the second insertion pattern.

Due to the difference in average length of the floating weft yarns, sections of the carpet that are obtained by means of the second insertion pattern are woven more tightly than sections of the carpet which are obtained by means of the first pattern of insertion. As a result, a carpet is made which includes lowered and raised sections. This relief formed of lowered and raised sections is particularly stable, since it is obtained by creating variations in the solid armor between the warp son and the weft son. This measurement making it possible to obtain a relief in the carpet is certainly not obvious for a person skilled in the art knowing the state of the art, since this person skilled in the art would rather be oriented towards the refinement of conventional methods for creation of relief, like the establishment of loops of different height.

In a preferred embodiment, the present invention provides a method according to the second aspect of the invention, wherein the longest floating weft yarn obtained according to said first insertion pattern overlaps at least two warp yarns juxtaposed by more than the longest floating weft yarn obtained according to said second insertion pattern. In other words, the longest floating weft yarn obtained according to said first insertion pattern passes over at least two more juxtaposed warp yarns than the longest floating warp yarn obtained according to said second yarn pattern. 'insertion. In this way, in one embodiment, the longest floating weft yarn obtained according to said first insertion pattern overlaps three juxtaposed warp yarns while the longest floating weft yarn obtained according to said second insertion pattern does not overlap. only one warp.

In a preferred embodiment, the longest floating weft yarn obtained according to said first insertion pattern overlaps at least three more juxtaposed warp yarns than the longest weft yarn obtained following said second insertion pattern. In this way, in one embodiment, the longest floating weft yarn obtained according to the first insertion pattern overlaps four juxtaposed warp yarns while the longest floating weft yarn obtained according to the second insertion pattern does not overlap. only one warp.

In a preferred embodiment, the present invention provides a method according to the second aspect of the invention, wherein said insertion patterns are formed alternately in the direction of the warp and / or in the direction of the warp. In this way, it is possible to manufacture a carpet with a plurality of said lowered or elevated areas or sections. In some embodiments, the same insertion pattern is thus repeated several times following the direction of the warp and / or the direction of the warp. In this way, the dimensions of said lowered and elevated sections in the carpet may vary. In a specific embodiment, the first insertion pattern is thus repeated twice in succession in the direction of the warp, after which armor between weft threads is then made in the direction of the warp. and warp threads according to the second insertion pattern.

EXAMPLE

The Figure 1 illustrates an embodiment according to the present invention for inserting weft yarns with respect to warp yarns. More specifically, the Figure 1 is a plan view of an armor that forms the surface of a carpet according to a preferred embodiment of the invention. This shows the side of the carpet that is visible in normal use and can be walked on. In the Figure 1 the visible portions of warp threads K1 can be seen as hatched areas and the visible portions of weft threads I1 can be seen as unhatched areas. The weft threads are inserted and woven along the axis II while the warp threads are placed along the KK axis. The weft threads are essentially perpendicular to the warp threads. The armor is executed by means of a 1-2-3-4 insertion pattern and has a first zone Z1 which connects to a second zone Z2. The Figure also shows that the frame 1 of the insertion pattern in zone Z2 comes more often to the surface than in zone Z1. The average length of the floating weft yarns obtained according to the first zone Z1 is significantly shorter than the average length of the floating weft yarns obtained according to the second zone Z2. In addition, the longest floating weft yarn obtained according to the first zone Z1 is significantly shorter than the longest floating weft yarn obtained according to the second zone Z2. As a result, the zone Z1 presents from a relative point of view a low relief and the zone Z2 presents from a relative point of view a high relief. In addition, the longest named first weft yarn passes over seven successive warp yarns, while said second longer floating weft yarn passes only over a single warp yarn. In addition, the armor obtained according to the first zone Z1 comprises several floating weft threads which overlap at least two successive warp threads. In this way, by means of the armor following the first zone Z1, a section of the belt is obtained that is higher than a section corresponding to the armor along the second zone Z2.

The Figure 2 schematically shows a carpet with transverse areas high relief (not hatched, Z2, Z4, Z6, Z8) and low relief (hatched, Z1, Z3, Z5, Z7). The high and low relief areas are arranged next to each other in the weft direction and connect to each other. The alternation of high and low relief accentuates the relief effect, whereby the carpet takes on a curved shape.

The Figure 3 schematically shows a carpet with shaded areas with high relief (not hatched, X2Y1, X4Y1, X6Y1, X1Y2, X3Y2, X5Y2, X2Y3, X4Y3, X6Y3) and with low relief (hatched, X1Y1, X3Y1, X5Y1, X2Y2, X4Y2, X6Y2, X1Y3, X3Y3, X5Y3). The high and low relief areas are arranged next to each other in the weft direction and in the warp direction, and are connected to each other. Thanks to the alternation of the relief zones, the carpet acquires a unique three-dimensional effect.
