Description

BACKGROUND OF THE INVENTION The present invention relates to a knitted ribbon consisting of a basic warp knitting weave and a weft-laying of two threads running opposite one another. stitches, wherein the at least one weft thread extends below the stitches of the entire row from one edge to the other edge of the ribbon and the method of making the knitted ribbon.

Several embodiments of knitted ribbons are known according to their manufacturing process. In one case, the wide knit is cut into narrow strips according to the width of the ribbons, wherein the wide knit is produced in various combinations of basic warp weaves or in combination of these with continuous weft laying from one edge of the article to the other edge. This group of knitted ribbons also includes wide knitted fabrics in which the stitch columns are joined by placing them under needles of different lengths. Wide: the knitted fabric is fixed and refined after removal, then cut to the desired width of the individual ribbons.

The disadvantage of this embodiment and the technological process of manufacturing ribbons are the frayed edges of the ribbons, which, moreover, lack solid edges, production is complex and requires further operations on a special device, which is expensive and reduces labor productivity.

In another case, knitted ribbons are also made

206871 - -----__ with a fixed edge in various combinations of bases, their warp ties, or in the form of pillars joined by laying under needles of different lengths, while a plurality of ribbons are juxtaposed together by threads which during the editing process.

Disadvantages of this process of manufacturing ribbons include the need to treat wide knits, which is a problem. Even an extra manufacturing operation is costly and increases; demands for further handling before treatment of ribbons and when. customized ribbons on a special, quite expensive and complex processing equipment. j

In another case, the individual knitted ribbons are manufactured separately, mainly in a coarser design, such that the stitches of the chain stitches are joined by weft laying from one thicker yarn that runs under the stitches of the entire row of knitting from one edge to the other. solid edges ί ribbons, but at the cost of using a special laying device.

^! The described technological process requires warp knitting machines and I equipped with a special single-purpose and placement device ¹ exchanges that reduces the production of:

^{1 of the} machines as a result of the need to merge the operation of the said laying device with the holding device. The construction of the laying device does not allow the two weft threads to be laid against each other or even

Fig. 6 is a longitudinal direction in full sleeve; putting two knit ribbons side by side with two | the weft threads against each other in each row with the empty needles indicated at the edges of the ribbons.

FIG. 1 shows a knitted ribbon which consists of chain eyelets 1 forming the base of the knitted ribbon. The chain loops 1 bind the weft yarns 2 on the reverse side of the knitted fabric in each row Rj áž R _{3 of the} weft yarns 3 and 4, which in the edges form curves 5 and 6 against each other.

According to FIG. 2, the knitted ribbon consists of chain eyelets 1 and 1 'forming the base of the knitted ribbon. The chain loops 1 bind the weft loops 2 on the reverse side of the knitted fabric to the rows R ₂ , R _{4 of the} weft threads 3 and 4, which in the edges form curves S and 6 against each other. Rows R ₂ , R ₄ of shorter chain stitch length 1 '; do not bind weft threads 3,4.

FIG. 3 shows a knitted ribbon of chain stitches 1 forming the basis of the knitted ribbon. The chain loops 1 bind the weft loops 2 on the reverse side of the knitted fabric in each row R _x to R _{3 of the} weft yarns 3 and 4, which in the edges form curves 5 and 6 against each other. A warp of coarse threads 17 extends in the longitudinal direction between the chain eyelet columns 1, which largely fills the gaps between the chain eyelet columns 1 and narrows it. As shown in this figure, the warp threads 7 laid in the longitudinal direction are bound in the face and back sides by the weft threads 3 and 4.

According to FIG. 4, the knitted ribbon consists of chain eyelets 1 forming the base of the knitted ribbon. Řetízková; the eyelets 1 bind with ruby loops 2 on the reverse side ;; knits in each row R _x to R ₃ weft yarns; 3 and 4, which in the regions create arcs 5 and 6 against each other. Between the two edge posts S _x and S _{8 of the} chain lugs 1, on both sides of the ribbon, in the longitudinal direction, a further warp of coarse threads 7 in the pattern sleeve runs. Threads 7 filling the marginal gap between the full number of columns S ₂ to S _{7 of} the chain-stitches 1 which taper in this way. The warp threads 7 laid in the longitudinal direction are bound from the front and back side by weft threads 3 and 4.

FIG. 5 shows a knitted ribbon of chain stitches 1 forming the base of the knitted ribbon. Chain stitch bind rubními 1 loop 2 on the reverse side of the fabric in each row R to R _{2 with} weft yarns 3 and 4. The weft yarn 3 extends below the entire loop 1 ί line _p R _4, R _s, while in row R _2, R ₃ is bound by the stitches 1 of the column S _{ť »The} weft thread 4 runs under the stitches 1 of the whole row R ₂ , R ₃ > while in the row R _x it is bound by the stitches 1 of the column S ₄ and in rows R ₄ and R _{5 2} , S ₃ , S ₄ . In all the rows R to R are _the arches 5, 6 against each other. Between the columns S _t to S _{4 of the} chain stitches 1 there are further warps) or further warps in the longitudinal direction. A drawback is also the weft laying in each row, not in any chosen row.

The above-mentioned disadvantages of the known embodiments of knitted ribbons are overcome by the invention, which is based on a new design knitted ribbon comprising at least one basic single-faced oscillating weave in various layouts combined with weft laying and comprising two weft yarns facing each other. one extending below the stitches of the entire row from one edge to the other edge of the knitted fabric, the returning weft yarns forming arcs against each other in the knitted ribbon.

According to one aspect of the invention, the knitted ribbon comprises two weft threads in each row, according to the invention.

; a different flag in every second, third, or arbitrarily selected line. Knitted ribbon ¹ is POSSIBLE but preferably amplify and zestejnoměmit that becomes entangled at least one other warp binding between the two weft threads loops extending below the whole row in the longitudinal direction between the wales. The at least one further warp may be in full or exemplary sleeve.

The method of making knitted ribbons according to the invention is characterized in that the two weft yarns are laid in any row against each other by two laying machines around one or both empty knitting needles adjacent to the needles forming the outermost stitch pillars to which the weft yarns are bound, the stringing of the laying apparatus corresponds to the width of the individual ribbon made on the knitting and needles, which it would not be possible to produce without the use of empty knitting needles.

Knitted ribbons produced by the method of the invention exhibit two weft yarns facing each other in one stitch row, giving the ribbon the character of a woven ribbon with higher stability in all directions compared to known knitted ribbons. The new ribbons are characterized by a better, regular aesthetic appearance than, for example, knitted ribbons in the form of pillars, joined by placing them under needles of different | length. The advantage of the new method of production of ribbons is mainly in the possibility of using the existing warp knitting machines without the need for an additional single-purpose laying device. Another advantage is the higher performance and production of warp knitting machines compared to ribbon machines and the possibility of using knitted ribbons for some special purposes. Furthermore, various binding structures can be formed similar to fabrics, such as twill, linen, and the like, by the length of weft yarn laying in the selected staple in succession. According to the invention, it is possible to create completely new binding designs including double-sided patterns or loops.

Further advantages and features of the knitted ribbons of the invention result from the accompanying drawings, wherein FIG. 1 shows a knitted ribbon with two weft yarns facing each other, FIG. 2 shows a knitted ribbon with two weft yarns facing each other, FIG. 3 weave of knitted ribbon with two weft yarns facing each other,. In the longitudinal direction, another warp of coarser yarns 7, in which even the greater part fills the gaps between the columns S _r to S _{4 of the} chain eyes 1 and narrows them. The warp threads 7 laid in the longitudinal direction are bound from the face and back sides by the weft threads 3 and 4.

; Fig. 6 is a schematic illustration of laying two unconnected knitted ribbons side by side. By means of the illustrated direct laying 1, the chains are formed on all knitting needles except for unoccupied knitting needles 8, around which they however lay the weft yarns 3 and 4, forming the arcs 5 and 6 against each other. In this case, the unoccupied knitting needles 8 serve as temporary auxiliary

J 206871 means for retaining the weft yarns 3 and 4 during a long return, which would normally bend the knitting needles forming the stitch edge columns, causing the stitches to fall. Long reversible laying around unoccupied knitting needles ₍ 8 prevents this undesirable effect.

i For simplicity and easier imagination, all of the figures show a knitted ribbon only; ! in basic single-chain chain binding. However, it is also clear that in practice, other types of warp seams can be used in the base of knitted ribbons | bindings. '-'
