Description

A WOVEN COVER This invention relates to woven fabric covers having an elongated cut provided deliberately to the cover to allow a belt, tape or other elongated object to pass again therefrom, and a method of forming such a cover.

BACKGROUND The invention is useful in machine weaving on weft knitting machines having independently operable needles displaced in two needle beds, for example, a flat "V" bed machine producing mainly a fabric of double fine yarn structure.

It has recently been found that it is possible to weave one-piece upholstery covers that removes the need to cook together parts of the cover. In British Patent 2,223,034, the applicant describes a method for knitting one piece covers for the base and / or back cushions of a motor vehicle seat.

Motor vehicle seat covers and / or trimmed panel covers may require that the provision on the cover be provided for the passage through it of a particular belt for the vehicle seats a belt may be required. security that passes through the cover to anchor to the seat frame, or in the case of a panel anchored to the vehicle frame.

Object of the Invention The present invention provides a woven cover and a method for knitting a cover, containing the provisioning of the passage of a seat belt.

Declarations of the Invention According to the present invention there is provided a cover for an object, the cover comprises woven fabrics of double fine yarn weft having at least one groove or cut in the direction of course in the fabric at least one edge of alcorte extending in an overlapping part comprising additional courses which overlap the other edge of the cut.

The overlapping part helps to hide the object inside the cover of a person observing so that the object can not be easily seen.

A single double worsted fabric, a fabric which can be produced on a single row of needles has a technical face side, which is produced in contact with the needle bed, and a technical reverse side which is remote of the bed of needles. Where such fabric is produced on a V-bed machine technical side of the fabric is the side of the fabric closest to the center line of the bed V.

In a production of conventional woven fabrics, the technical face of the fabric is the face seen by the wearer and / or usually the face on the outside of the garment.

A fine double yarn structure by comparison, is produced on both beds of a V-bed weaving machine, and has in effect a pair of ribbons connected by the interenganche fabric loops. It will be appreciated, therefore, that the double thin yarn structures tend to be heavier in weight than the unique thin yarn structures.

The application of the present invention uses both single fine yarn and double fine yarn weaving techniques.

Preferably, the overlapping portion comprises a plurality of courses of a single fine woven fabric. The cut in direction of the course can be formed through aligned courses of both layers of double thin yarn, on one side of the layers the two edges of the cut extend into a pair of fins of single fine yarn, which can be pushed to through the groove formed in the outer layer.

Alternatively, the cut in the direction of the course may be formed in aligned courses of both layers of double thin yarn, the two cuts of each cut extending like a pair of fins of a single thin yarn tube construction whose fins may be pushed through the cut.

In another embodiment the cover includes a tubular portion of single fine yarn integrally formed with the double thin yarn cover and at least one end of the tubular part of single fine yarn constitutes a cut in the direction of the course and preferably said end of the part. of single tubular fine yarn opens to the other side of the double fine yarn fabric, said overlapping part being at one end of the tubular part and being able to wrap itself inside the tubular part.

In a further embodiment the overlapping part is a part of double fine yarn, and there is a second cut in the direction of the course aligned with the first cut and spaced by several courses thereof and which also has an edge which extends inside the overlapping part of double fine yarn which can overlap the first overlapping part.

Also according to the invention there is provided a method for forming a cut in the direction of the course in a weft woven cloth cover which is woven on a weft knitting machine having needles placed on at least two independently operable needle beds. , wherein the fabric is woven on both needle beds in a construction primarily of double fine yarn and a predetermined course in at least one selected group of consecutive needles on one or both beds of continuous needles for knitting with other needles on each side of the same kept and therefore form a fin, the fabric then recommences on both beds of needles to continue the construction of double fine yarn from said predetermined course.

Preferably, said group of needles are released after weaving a plurality of courses to form said fin and conveniently said selected group of needles on both needle beds continue to knit from said predetermined course said fin as a thin double yarn construction fin, said group of needles take stitches to restart the fabric from said predetermined course.

Preferably when restarting the fabric, the needles on both needle beds weave a double fine yarn fabric up to a predetermined second course wherein the stitches on both sets of needles are released and both groups of needles then take new stitches and weave a plurality of stitches. courses while the needles on each side of the groups are held until they form a second letter and then continue to knit on all the needles after the formation of said second letter.

Alternatively, said fabric is woven with said selected group of needles forming a tubular part of single fine yarn, and in a predetermined course a group of needles on a needle bed only continues to knit to form a single fine yarn construction fin with the other needles defined.

In an additional embodiment in a predetermined course said selected group of needles on both needle beds continues to weave a single thin stamen tube to form a single fine stamen tubular loop which is subsequently separated along a line of course to form a pair of tubular fins of single fine yarn with open ends.

In yet another embodiment in said predetermined course for said group of needles the stitches on a needle bed are pulled and / or transferred to the other needle bed, and a single fine yarn loop is formed by the fabric on said needle group. on the other bed of needles whose loop is subsequently cut along a course line to form a pair of single course fins.

The woven fabric is woven from a yarn of ultifilaments preferably a polyester yarn which can be air textured. The yarn can be chenille yarn as described in the published application of the applicants EP-A-0627,516.

Figures 3 and 4 show a second woven fabric according to the present invention; Figure 5 and Figure 6 show a third woven fabric according to the present invention.

Figure 7 and Figure 8 show one embodiment of the present invention.

Figure 9 and Figure 10 show a fifth embodiment of the invention, and Figure 11 shows a sixth embodiment of the invention.

Detailed Description With reference to the drawings, each set of drawings constitutes a schematic plan view and a cross-sectional side view through a cut in the direction of the course formed in a fabric part 11 forming part of a car seat cover. which is woven of relief continuously of unique operation. The fabric cover is of a mainly double thin yarn construction and is woven on a "V" bedding machine provided with a conventional press stand device and / or other loop retainer to hold the woven fabric between the beds of opposite needles of the machine. A woven direction in each set of drawings is in the direction of the arrow "A" which is from the bottom to the top of each pattern so that the reliefs of pieces of fabric extend vertically upwards in each diagram and the courses are fully extended in each diagram.

The fabric of a complete seat cover is described in detail in British Patent GB-A-2,223,034 and will therefore be decided here to give an understanding to the present invention.

Now, with reference to figure 1 and the figure 2 shows a part 11 of a seat cover which is virtually formed of a woven fabric of double fine yarn relief of the fabric part 11 is formed with a cut in the direction of the course 12 on it to allow the passage through the fabric of a weaving belt or other elongated member. The lower edge 12a of the cut 12 extends from a fin 13 comprising a plurality of courses woven of double fine yarn. The letter 13 overlaps the other edge 13.

A second cut in the direction of the course 14 is located in the double fine yarn fabric 11 in alignment with the first cut 13 so that there is a band 15 of a fine double yarn fabric several courses wide between the two cuts. A second letter 16 extends from the upper edge 14B of the second cut 14 and is of a sufficient number of courses to cover virtually the letter 13.

The cloth cover including the part 11 is woven on two independent needle beds and is woven into a fine double yarn structure to a predetermined course "A". When you reach the "a" course, the needles to the left of the line x of needles and to the right of the needle line stop, and the group of consecutive needles between the needles x and continue to knit on both needle beds for about few courses (about 10 and a 12 course) to form the letter 13. The stitches on the needles x and on both needle beds are then not pressed.

The needles between x-y (on both needle beds) take new loops to form the courses set in all the needles so they continue to weave around 20.25"b" courses. In course "b" the stitches on the needles x and on both beds are then released and taken again to form the established courses and weave a plurality of courses around 25-30 courses, while the needles outside of x and remain . This forms the second letter 16. Then the needles on both beds weave to form the rest of the double fine worsted fabric.

Now with reference to Figures 3 and 4, a part 31 of a seat cover of a woven fabric of double fine yarn relief having a cut in direction of the course 32 formed therein is shown.

On one side F of a fabric the upper and lower edges 32a and 32b of the cut 32 each extend the cut 1 inside of a single fine yarn construction fin 33 and 36 respectively, on the rear face A of the fabric the upper edge B of cut 32 extends into a small single fine stamen construction fin 37. The two fins 33 and 36 can be tucked back through cut 32 to form sharper and more aesthetically pleasing edges to the cut 32 As before the material of the fabric is formed of a fabric of relief of fine double yarn on all the needles up to the course "a". On reaching the Ha course, the needles outside the x and y needles stop, and all the needles on the posterior needle bed between x and y are released and preferably the last course contains a fusible thread The needles on the front needle bed between x and y needles continue to weave a single thin yarn construction loop for about 40 courses.After about 30 courses are woven on the front bed, the rear bed needles between x and y begin to weave the fin of fine fin yarn. 37 for about 10 courses, the needles on both beds then retract the fabric of the double fine worsted fabric structure, this results in the formation of a double fine yarn structure having a cut 32 with a single fine yarn loop on the F side. The construction is similar to that described in the British published patent application 2,223,034 A. The upper part can be cut by either orthe or by including a pair of courses of a reliable thread during the weaving of the single fine yarn fins 33 and 36. Now with reference to F 5 and 6, as before a woven cloth of double fine stamen relief 61 has a cut in the direction of course 62 formed there. The upper and bottom edges 62b and 62a respectively of the cuts 62 each have a single fine stamen tubular fin 62 and 66 extending therefrom on the front face S.

The two tubular fins can be bent back through the cut 62 to the back of the fabric as shown in Figure 5b to present a more aesthetic front face F. As before the fabric of double fine yarn structure is woven on all the needles on both needle beds to the "a" course. In the "a" course the needles outside the X-Y needles stop while the needles between x and y continue to weave a tubular construction of single fine yarn for about 50-60 courses. After, all the needles are recommenced by weaving the fine double yarn fabric from the course "a" onwards.

The tubular loop of the single fine loop can be cut as before, this is cut or by the inclusion of a pair of reliable yarn courses incorporated therein, producing two tubular fins of single fine yarn 63 and 66. The fins 63 and 66 are of new pushed through the cut. In order to assist the fin to pass through the cut 62, the flap 62 can be pushed in that direction by weaving the extra courses on the front face relative to the rear face to push the flap.

With reference to FIGS. 7 and 8, the virtually double-thin staple fabric 71 is woven with a tubular portion of integral single fine yarn 81 extending to the width in the direction of the full course of the cut and capturing it to one side of the bottom edge. of the cut in the direction of the course 72. The bottom edge 72a of the cut extends into the cut of the single fine yarn tubular fin 73 and the upper edge 72b of the cut 72 also extends into a tubular fin of fine yarn of single flap 76. The two flaps 73 and 76 are shown extending from the front face F from the fabric and can be pushed back through the cut 72 as shown. A belt or knitting 82 shown in dotted line can be passed through the single fine worsted yarn flap 73 and the tubular part 81.

The double fine worsted fabric 71 is woven with a tubular part of single fine yarn 81 formed on the needles between x and y. When you reach the "a" course, the needles outside the needles x and y stop. The needles on both sets between x and y continue to weave as the tubes of single fine yarn as before for figures 5 and 6. Then all the needles restart the fabric of the double fine yarn fabric from the course "a" onwards.

The fins 73 and 76 are made as in figures 5 And 6.

With reference to figures 9 and 10 a part 91 of a cover of a similar construction is described which is described with respect to figures 7 and 8. The double fine worsted fabric 91 includes a single thin stamen tube part 101 which can have an open lower end 102 to the rear face R of the fabric. The tubular part of single fine yarn extends upwards to a cut in the direction of the course 92 formed at the upper end of the single fine stamen tube 91 and opens to the front face F of the fabric. The back layer of the tube of single fine yarn extends inside of double fine yarn material. The lower edge 92 A of the cut extends into a single fine yarn fin 93. The fin 93 can be tucked in the tube 101 as shown in Figure 9B. A belt or knitting 103 shown in dotted line can be passed through the single thin stamen tube 101 and the two cuts 102 and 92 as shown.

The double fine worsted fabric is woven to a predetermined course "v". In the "v" course the stitches on the rear bed needles between the needles x and y are released or transferred to the front bed. The needles between x and y are set and the additional fabric continues with the needles outside the needles x and knitting the double fine worsted fabric and the needles between x and y, weaving a single fine stamen tube 101. This continues to a predetermined course "a" . In the course "a" the needles outside the needles x and y on the back bed between x and y are maintained until the needles x and y on the front bed continue to knit to form a fin of single fine stamen 93. The stitches woven on the needles between x and y they are then released.

The front bed needles between x and y are then put on and with the other needles previously stopped, the fine double worsted fabric continues to be woven from course "a" onwards.

With reference to figure 11 this shows a part of the cloth 11 in similar structure that in figures 9 and 10 except that the single fine yarn tube increases in width progressively course by course, and the single fine yarn fin 123 decreases in width. width progressively course by course. A disguised conduit is provided for a weaving through the cover at an acute angle to the direction in the direction of the relief. On one side of the tubular part of single fine yarn is formed along a particular predetermined relief line.

The embodiment shown in Figure 11 is woven as previously described for the embodiment of Figures 9 and 10 except that when weaving the tubular part of single fine yarn 121 the width in the direction of the tube course is increased on a needle base per course.
