(31) The industrial textile 6 of FIGS. 1a to 1h has the weft ratio of 2:1.

(32) FIGS. 1b, 1d and if show clearly that the third machine direction yarn 3 participates in forming the bind both on the front side 7 and the back side 8 of the industrial textile 6.

(33) FIG. 2 shows the whole pattern of FIGS. 1a to 1h. The cross-machine direction yarns CMDY, i.e. the first cross-machine direction yarns 4 and the second cross-machine direction yarns 5 are shown on the left side of FIG. 2. In other words, if there is number 4 alone it means that there is only the first cross-machine direction yarn 4 but if there are numbers 4, 5 it means that there are the first cross-machine direction yarns 4 and the second cross-machine direction yarns 5 on top of each other.

(34) The machine direction yarns MDY, i.e. the first machine direction yarns 1, the second machine direction yarns 2 and the third machine direction yarns 3, are shown under FIG. 2.

(35) The first machine direction yarns 1 and the first cross-machine direction yarns 4 form the front side of the industrial textile 6.

(36) The second machine direction yarns 2 and the second cross-machine direction yarns 5 form the back side of the industrial textile 6.

(37) The third machine direction yarns 3, the first cross-machine direction yarns 4 and the second cross-machine direction yarns 5 interweave the front side and the back side together.

(38) The third machine direction yarns 3 and the first machine direction yarns 1 have common interlacing points 91 on the front side of the industrial textile 6. The whole surface of the industrial textile 6 is covered by the interlacing points 91. Examples of the interlacing points 91 are shown in FIG. 2.

(39) The third machine direction yarns 3 and the second machine direction yarns 1 have common interlacing points 92 on the back side of the industrial textile 6. The whole surface of the industrial textile 6 is covered by the interlacing points 92. Examples of the interlacing points 92 are shown in FIG. 2.

(40) FIGS. 3a and 3b show micro photos of the industrial textile 6 of FIGS. 1a to 1d and 2. FIG. 3a shows the paper side of the industrial textile 6 comprising first machine direction yarns 1, third machine direction yarns 3 and first cross-machine direction yarns 4. An example of a common interlacing point 91 on the front side 7 of the industrial textile 6 is also shown.

(41) FIG. 3b shows the machine side of the industrial textile 6 comprising second machine direction yarns 2, third machine direction yarns 3 and second cross-machine direction yarns 5. An example of a common interlacing point 92 on the back side 8 of the industrial textile 6 is also shown. The second machine direction yarns 2 and the third machine direction yarns 3 that form common interlacing points 92 are not necessarily adjacent but there may be a few machine direction yarns between the particular second machine direction yarn 2 and the particular third machine direction yarn 3 (as shown in FIG. 2).

(42) The weft ratio of the industrial textile 6 of FIGS. 3a and 3b may be 2:1 (the ratio of the first cross-machine direction yarns 4 to the second cross-machine direction yarns 5), i.e., 2:1 means that there are double first cross-machine direction yarns 1 compared to the second cross-machine direction yarns 2.

(43) FIG. 4a shows a paper side structure of an industrial textile 6. First machine direction yarns 1 and first cross-machine direction yarns 4 form a plain weave. A first machine direction yarn 10a repeatedly passes below one cross-machine direction yarn 4 and passes above one successive cross-machine direction yarn 4. The first machine direction yarns 10a, 10b next to each other are arranged in such a manner that when a coincidentally selected first machine direction yarn 10a is under a first cross-machine direction yarn 4 a first machine direction yarn 10b next to the coincidentally selected first machine direction yarn 10a is above the first cross-machine direction yarn 4.

(44) There are third machine direction yarns 3 between adjacent first machine direction yarns 10a, 10b, i.e., the first machine direction yarns 1 and the third machine direction yarn 3 alternate. A third machine direction yarn 3 repeatedly passes under three first cross-machine direction yarns 4 and above one first cross-machine direction yarn 4 on the paper side of the industrial textile 6.

(45) The third machine direction yarns 3 have interlacing points 71 with the first cross-machine direction yarns 4 where a third machine direction yarn 3 passes over a first cross direction yarn 4. The interlacing points 71 cover the whole surface of the industrial textile 6 on the paper side of the industrial textile 6 (black dots in FIG. 4a).

(46) The interlacing points 71 extend as parallel diagonal patterns over the paper side of the industrial textile 6. The interlacing points 71 between one first cross-machine direction yarn 4 and the third machine direction yarns 3 are offset compared to the interlacing points 71 that are above or below the particular first cross-machine direction yarn 4. For example, the first cross-machine direction yarn 40b has interlacing points 71b that are offset compared to interlacing points 71a or 71c. The offset may be ±1.

(47) Examples of common interlacing points 91 on the front side of the industrial textile 6 are shown in FIG. 4a.

(48) FIG. 4b shows a machine side structure of the industrial textile of FIG. 4a as it is seen from below. However, the structure is explained as it is seen from above (when it is under the paper side). Second machine direction yarns 2 and second cross-machine direction yarns 5 bind to each other in such a manner that a second machine direction yarn 2 passes over twelve second cross-machine direction yarns 5, under one cross-machine direction yarn 5, over two cross-machine direction yarns 5 and under one cross-machine direction yarn 5. The interlacing points 82 between one second cross-machine direction yarn 5 and the second machine direction yarns 3 are offset compared to the interlacing points 82 that are above or below the particular second cross-machine direction yarn 5. For example, the second cross-machine direction yarn 50a has an interlacing point 82a that is offset compared to an interlacing point 82g. The second pattern may have an offset of ±6.

(49) A third machine direction yarn 3 repeatedly passes under one second cross-machine direction yarn 5, over two second cross-machine direction yarns 5, under one second cross-machine direction yarn 5 and over twelve second cross-machine direction yarns 5.

(50) The third machine direction yarns 3 have interlacing points 72 with the second cross-machine direction yarns 5 where a third machine direction yarn 3 passes under a second cross-machine direction yarn 5. The interlacing points 72 cover the whole surface of the industrial textile 6 on the machine side of the industrial textile 6 (black dots in FIG. 4b). The third pattern may have an offset of ±6 on the machine side of the industrial textile 6.

(51) The third machine direction yarns 3 are an integral part of the bind on the front and back side of the industrial textile 6, i.e. the bind of the front side and the bind of the back side are incomplete without the third machine direction yarns 3. FIGS. 4a and 4b show clearly that the third machine direction yarn 3 participates in forming the bind both on the front side 7 and the back side 8 of the industrial textile 6.

(52) Examples of common interlacing points 92 on the front side of the industrial textile 6 are shown in FIG. 4b.

An example of a common interlacing point 92 on the back side 8 of the industrial textile 6 is also shown in FIG. 5b

(55) The weft ratio of the industrial textile 6 of FIGS. 5a and 5b may be 3:2 (the ratio of the first cross-machine direction yarns 4 to the second cross-machine direction yarns 5).

(56) FIGS. 6a to 6d show a bind of an industrial textile 6. A first machine direction yarn 1 repeatedly passes over one first cross-machine direction yarn 4 and under three first cross-machine direction yarns 4.

FIGS. 6b, 6d, 7a and 7b show clearly that the third machine direction yarn 3 participates in forming the bind both on the front side 7 and the back side 8 of the industrial textile 6.

(63) FIG. 7a shows a paper side structure of the industrial textile 6 of FIGS. 6a to 6d. There are first machine direction yarns 1, third machine direction yarns 3 and first cross-machine direction yarns 4. The first pattern comprises the first machine direction yarns 1 and the first cross-machine direction yarns 4 which are configured in the following manner: Each first machine direction yarn 1 passes below three first cross-machine direction yarns 4 and over one first machine direction yarn 4. The first pattern has an offset of ±1.

(64) There are third machine direction yarns 3 between adjacent first machine direction yarns 1. Each third machine direction yarn 3 repeatedly passes under three first cross-machine direction yarns 4 and over one first cross-machine direction yarn 4.

(65) The third machine direction yarns 3 have interlacing points 71 with the first cross-machine direction yarns 4 where a third machine direction yarn 3 passes over a first cross direction yarn 4. The interlacing points 71 cover the whole surface of the industrial textile 6 on the paper side of the industrial textile 6.

(66) Examples of common interlacing points 91 on the front side 7 of the industrial textile 6 are shown in FIG. 7a.

(67) FIG. 7b shows a machine side structure of the industrial textile of FIG. 7a as it is seen from below. However, the structure is explained as it is seen from above (when it is under the paper side).

(68) The second pattern comprises the second machine direction yarns 2 and the second cross-machine direction yarns 5 which are configured in the following manner: Each second machine direction yarn 2 passes under one second cross-machine direction yarn 5, over four second cross-machine direction yarns 5, under one cross-machine direction yarn 5 and over two second cross-machine direction yarns 5. The second pattern has an offset of ±2.

(69) The third machine direction yarns 3 have interlacing points 72 with the second cross-machine direction yarns 5 where a third machine direction yarn 3 passes over a second cross direction yarn 5. The interlacing points 72 cover the whole surface of the industrial textile 6 on the paper side of the industrial textile 6.

(70) Examples of common interlacing points 92 on the front side 7 of the industrial textile 6 are shown in FIG. 7b.

(71) FIGS. 8a to 8f show a bind of the industrial textile 6. In FIG. 8a a first machine direction yarn 1 passes under three first cross-machine direction yarns 42a, 42b, 42c, over one first cross-machine direction yarn 42d, under three first cross-machine direction yarns 42e, 42f, 42g and over one first cross-machine direction yarn 42h.

(72) A second machine direction yarn 2 passes under one second cross-machine direction yarn 52a and over seven second cross-machine yarns 52b, 52c, 52d, 52e, 52f, 52g, 52h.

(73) In FIG. 8b a third machine direction yarn 3 passes over one first cross-machine direction yarn 42a, under three first cross-machine direction yarns 42b, 42c, 42d and one second cross-machine direction yarn 52c, over one first cross-machine direction yarn 42e and under three first cross-machine direction yarns 42f, 42g, 42h.

(74) In FIG. 8c a first machine direction yarn 1 passes over one first cross-machine direction yarn 42a, under three first cross-machine direction yarns 42b, 42c, 42d, over one first cross-machine direction yarn 42e and under three first cross-machine direction yarns 42f, 42g, 42h.

(75) A second machine direction yarn 2 passes over five second cross-machine yarns 52a, 52b, 52c, 52d, 52e, under one second cross-machine direction yarn 52f and over two second cross-machine direction yarns 52g, 52h.

(76) In FIG. 8d a third machine direction yarn 3 passes under one first cross-machine direction yarn 42a, over one first cross-machine direction yarn 42b, under three first cross-machine direction yarns 42c, 42d, 42e, over one first cross-machine direction yarn 42f, under two first cross-machine direction yarns 42g, 42h and one second cross-machine direction yarn 52h.

(77) In FIG. 8e a first machine direction yarn 1 passes under one first cross-machine direction yarn 42a, over one first cross-machine direction yarn 42b, under three first cross-machine direction yarns 42c, 42d, 42e, over one first cross-machine direction yarn 42f and under two first cross-machine direction yarns 42g, 42h.

(78) A second machine direction yarn 2 passes over two second cross-machine yarns 52a, 52b, under one second cross-machine direction yarn 52c and over five second cross-machine direction yarns 52d, 52e, 52f, 52g, 52h.

(79) In FIG. 8f a third machine direction yarn 3 passes under two first cross-machine direction yarns 42a, 42b, over one first cross-machine direction yarn 42c, under three first cross-machine direction yarns 42d, 42e, 42f and one second cross-machine direction yarn 52e, over one first cross-machine direction yarn 42g and under one first cross-machine direction yarn 42h.

(80) The third machine direction yarns 3 are an integral part of the bind on the front and back side of the industrial textile 6, i.e., the bind of the front side and the bind of the back side are incomplete without the third machine direction yarns 3. FIGS. 8b, 8d, 8f, 9a and 9b show clearly that the third machine direction yarn 3 participates in forming the bind both on the front side 7 and the back side 8 of the industrial textile 6. FIG. 9a shows the paper side structure of the industrial textile 6 of FIGS. 8a to 8f. The third machine direction yarns 3 have interlacing points 71 with the first cross-machine direction yarns 4 where a third machine direction yarn 3 passes over a first cross direction yarn 4. The interlacing points 71 cover the whole surface of the industrial textile 6 on the paper side of the industrial textile 6.

(81) Examples of common interlacing points 91 on the front side 7 of the industrial textile 6 are shown in FIG. 9a.

(82) FIG. 9b shows the machine side structure of the industrial textile of FIG. 9a. The third machine direction yarns 3 have interlacing points 72 with the second cross-machine direction yarns 5 where a third machine direction yarn 3 passes under a second cross-machine direction yarn 5. The interlacing points 72 cover the whole surface of the industrial textile 6 on the machine side of the industrial textile 6 (black dots in FIG. 7b).

(83) FIG. 9c shows illustratively that the third machine direction yarns 3 are an integral part of the bind on the front and back side of the industrial textile 6, i.e. the bind of the front side and the bind of the back side are incomplete without the third machine direction yarns 3.

(84) It will be obvious to a person skilled in the art that, as the technology advances, the inventive concept can be implemented in various ways. The invention and its embodiments are not limited to the examples described above but may vary within the scope of the claims.

(85) It should be understood that a bind means the structural arrangement of yarns in a woven fabric. A bind (of an industrial textile) is the arrangement of warp and weft yarns which form a fabric.
