When in operation, the four pages of heald frames have the following operation rule: the page 1 frame 21 and the page 3 frame 23 are lowered simultaneously and the page 2 frame 22 and the page 4 frame 24 are raised simultaneously.
The first page of heald frame, the second page of heald frame, the third page of heald frame and the fourth page of heald frame are sequentially and circularly provided with a 1 st group of heddles, a 2 nd group of heddles, a 3 rd group of heddles and a 4 th group of heddles.
When the number of the heddles of any group of heddles on any one page of heald frame is more than or equal to 2m, the group of heddles form 2 parallel dividing lines, 4 parallel dividing lines, 6 parallel dividing lines, 8 parallel dividing lines, and the number of the heddles of other groups of heddles is 1 in a conventional arrangement. m is a positive integer.
When the number of the heddles of the adjacent groups of the heddles on any two adjacent pages of heald frames is equal to or more than 2, the adjacent groups of the heddles form 2@2 and 4 dividing lines, 3@3 and 6 dividing lines, 4@4 and 8 dividing lines, and the number of the heddles of other groups of the heddles are set conventionally and are all 1. Wherein the number of warp threads in each heddle is 1.
The harness wires forming the cord fabric dividing line are non-white harness wires, and the warp wires are non-white warp wires, such as red harness wires and warp wires. The color is striking, and the identification, counting and cutting are more convenient.
Because of the difference of the cutting width of the tires of different users and different models, in the weaving process of the grey cloth of the cord fabric, the parallel cutting lines with different numbers can be woven according to the variety specification, the organizational structure design and the change of the harness wire threading method.

According to the invention, different harness wire drafting methods are designed and used according to the cord fabric variety structure and the number of warp threads when the white blank cord fabric is woven, the original drafting rules of 1, 2, 3 and 4 are broken, and the drafting rules of (1, 1), 2, 3 and 4 are adopted; 1. (2, 2), 3, 4; 1. 2, (3, 3), 4; 1. 2, 3, (4, 4); (1, 1), (2, 2), 3, 4; 1. (2, 2), (3, 3), 4; 1. 2, (3, 3), (4, 4); (1, 1), (2, 2), 3, 4; 1. (2, 2), (3, 3), 4; 1. 2, (3, 3), (4, 4); ... the design principle weaves the cloth surface of the cord fabric into patterns, and the desired cutting position can be quickly found according to the change of the number of warps in the patterns. The grey cloth produced by the new drafting method can still obviously show the pattern change after the cord fabric is subjected to gum dipping and stretching and calendering in a rubber factory, and can be cut by a lower cutter quickly, so that the use requirement of a user is greatly met.
The specific application case is as follows:
as shown in fig. 4: 199 th and 200 th warp threads are threaded on the same page of heald frame, and 201 th and 202 th warp threads are threaded on the other page of heald frame; the 287 th and 288 th warp threads are threaded on the same heald frame, and the 289 th and 290 th warp threads are threaded on the other heald frame; 359 th warp threads and 360 th warp threads are threaded on the same heald frame, and 361 th warp threads and 362 th warp threads are threaded on the other heald frame; 479 th and 480 th warp threads are threaded on the same heald frame, and 481 th and 482 th warp threads are threaded on the other heald frame; the 575 th warp threads and the 576 th warp threads are threaded on the same heald frame, and the 577 th warp threads and the 578 th warp threads are threaded on the other heald frame; the 719 th and 720 th warp threads are threaded on the same heald frame, and the 721 th and 722 th warp threads are threaded on the other heald frame; the others are analogized as the warp positions shown in fig. 4. The weaving process is executed by the penetration number of each hole of the front reed. After weaving, 11 parts of the split lines are seen on the whole width of the curtain fabric like a parallel end, and the whole width of the fabric is divided into 12 parts which are symmetrical left and right but are not uniform.
The above-described embodiments are merely preferred embodiments of the present invention, and not intended to limit the scope of the invention, so that equivalent changes or modifications in the structure, features and principles described in the present invention should be included in the claims of the present invention.
