Detailed Description
In the invention, the difference between the adhesion net sheet 1 and the existing knotless net and knotted net is as follows: as shown in fig. 1a and 1b, the intersection points of the net feet of the knotless net are not provided with net knots and are formed by combining balanced rhombic warp knitting tissues and weft insertion grouping and weaving, the intersection points of the net feet of the knotted net are provided with the net knots, as shown in fig. 2a and 2b, the net knots protrude towards the periphery, each net knot is tightly fastened and connected with four net feet, the adhesion net piece comprises a conventional net piece 1 and an adhesion piece structure 2, and two adjacent conventional net pieces 1 are connected through the adhesion piece structure 2; the adhesive sheet structure 2 comprises at least one row of net feet, as shown in fig. 3a and 3b, which are formed by interweaving open or/and closed warp knitted chain stitches (fig. 4). The number of rows of net feet arranged in the adhesion sheet structure 2 can be set according to the use environment of the net sheet and the thickness of the net line, and the producer can select the open warp knitting chain organization or the closed warp knitting chain organization.
In this embodiment, the adhesive sheet structure 2 is L 1 、L 2 、L 3 、L 4 、L 5 、L 6 And L 7 A total of 7 rows of guide bars are woven, and the movement of each row of guide bars is driven by a separate chain block; l is 1 、L 2 、L 3 、L 4 、L 5 、L 6 And L 7 The technological chain arrangement of each row of guide bars in the row guide bars is as follows:
L 1 ：4224×6,2442×5；
L 2 ：4664×6,6446×5；
L 3 ：4400×11；
L 4 ：4488，4466×5,2266,4466×4；
L 5 ：4400，4422×5,6622,4422×4；
L 6 ：2266,4466×4,4488,4466×5；
L 7 ：6622,4422×4,4400,4422×5。
for the knotless net shown in fig. 1a and 1b, the knitting is usually performed by using row guide bar looping and 4 row guide bars as weft insertion process, and the row chain of each row guide bar process is as follows:
L 1 ：2446,4224×4,2024,4224×4；
L 2 ：6442,4664×4,6864,4664×4；

in general warp knitting knotless nets, lapping is realized by the front and back swing of a guide bar between latch needles and the movement along the latch needle plane, the front and back swing of the guide bar between the latch needles is driven by an eccentric link mechanism, and the movement along the latch needle plane is driven by a chain block on a pattern knitting wheel. At this time, the tongue bed moves only up and down. However, in some net-knitting machines, in order to reduce the amplitude and time of the front-back swing of the needle bed of the guide needle, the latch needle moves up and down and also swings against the guide bar of the guide needle, which plays a certain role in buffering the tension of the yarn and reducing the breakage of the yarn.
As can be seen in FIG. 6, L 1 And L 2 The guide bars being moved in loops, L 3 And L 4 The row guide bar makes a yarn laying motion with small needle moving amplitude, L 5 And L 6 Laying movement with large needle shifting amplitude of row guide bar, L 3 ～L 6 Weft insertion quilt L 1 ～L 2 The rows are locked and tightened to form knotless net tissue.
The adhesion net sheet of the invention is mainly different from the common knotless net: the conventional mesh sheets 1 are bonded together by the adhesive sheet structure 2, and no mesh is formed in the adhesive sheet structure 2. When the conventional mesh sheet 1 is a knotless mesh sheet, the adhesive mesh sheet can be obtained by improving the general knotless mesh process and adding a plurality of groups of inserting weft insertion threads to adhere mesh legs at two sides of the conventional mesh sheet together.
The weft insertion guide bar and the looping guide bar are mainly different in that: the weft inserted weft yarn does not move transversely absolutely in front of the latch needle, so that the weft yarn cannot be hooked by the latch needle to form a loop, and only moves transversely on the back of the latch needle, so that the weft yarn is pressed by the extending line of the loop and tightly clasped with the loop. The looped yarn must traverse before the latch needle, and the yarn is hooked by the latch needle to form a loop.
The simplest method for knitting the warp knitting mesh structure is to fill yarns on each transverse line by each needle of two guide bars, so that the coils are connected without falling off, the formed wales are not interrupted, the coils in two adjacent longitudinal and transverse lines at the turning coil are not connected, the adjacent coils in the same longitudinal line are padded in opposite directions, and thus 2 coils in the transverse line in opposite directions are used as two sides to form a quadrangle similar to a rhombus. When the yarn laying of the former bar is changed to another needle, the yarn is exchanged with the latch needle yarn laying, 2 loops are needed to be connected, and then the original latch needles are respectively returned. That is, the warp plain weave is adopted, so that the number of the unconnected transverse rows of the longitudinal rows is increased, and a larger mesh effect is formed, which is the basic method for forming the warp knitting mesh.
In accordance with this principle, fig. 7 is briefly explained:
for L 1 、L 2 Looping guide bar, chain block middle L 1 (4224、2442)，L 2 (4664, 6446) are made of open or closed warp knitted chain stitch, and no flat stitch forms mesh, all "mesh knots" are close together.
For the guide bar chain block L 3 (4400) The repeated arrangement is carried out, and the weft insertion needle back lapping yarns with two needle pitches are pressed by the loop forming loops of the two needles and the extension lines thereof. This more tightly binds the warp flat tissue at the "knot" junction.
For the guide bar chain block L 4 、L 5 、L 6 、L 7 The weft insertion simply carries out the needle back yarn laying movement. L is a radical of an alcohol 4 、L 5 、L 6 、L 7 Inlay weft inlay and L 1 ，L 2 The looping is carried out synchronously, the weft insertion guide bar does not transversely move before the latch needle and then swings to the needle back, and the looping guide bar moves one needle before the latch needle to carry out yarn laying looping, so that the weft insertion is clamped between an old coil and an extension line which is about to form a new coil. That is, when a new loop is formed, the weft-insertion is sandwiched between the old loop and the extension line of the new loop, and then the weft-insertion is turned, like an S-shaped weft-insertion, and is inserted into the loop, so that the loop is more compactly folded, and the net sheet is more compactly foldedThe strength is greater.
Although each row is moved independently, the movement is not isolated, but the rows of guide bars are moved simultaneously, and the rows of guide bars are interlaced with each other to form the mesh tissue, as shown in fig. 8.
Fig. 6 and 7 are diagrammatic views used within the industry to represent the movement of the yarn: each row of small black points represents a vertical section of the latch needle, the position above the points is in front of the latch needle, the position below the points is behind the latch needle, and the transverse distance of the black points is the distance between the latch needles and is also equal to the height difference of adjacent process chain blocks. When the yarn winding device works, the latch needle is static, the yarn guide needle carries the yarn to perform yarn winding movement, and according to the relativity of the movement, the strong track of the yarn on the latch needle is drawn to be the artistic drawing shown in the drawing. The artistic conception drawing method of the warp knitting chain organization comprises the following steps: the yarns of the open chain are transversely moved in front of the latch needle, the needles are moved forward from left (right) to right (left), and the forward needles are moved forward from right (left) to left (right) to return to the original positions to form 2 loops. Such as a repeating arrangement of chain blocks (02, 20). The yarns of the closed chain are required to respectively traverse 1 time before the latch needle and 1 time after the latch needle every time 1 loop is formed, traverse is performed from the front of the needle and then from the back of the needle to return to the original position, the yarns are also wound around the latch needle, and if the chain blocks are arranged to be (02,02) repeatedly arranged.
The mesh-free adhesive sheet structure 2 is formed by adhering a plurality of rows of net feet together, when the conventional net sheet 1 is damaged, the damaged notch cannot stretch to other conventional net sheets under the interception of the adhesive sheet structure 2, and therefore large-area damage of the net sheets is reduced.

Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments.
