Description

  The present invention relates to a method for producing a bag-like mesh body having corners, and a bag-like square mesh produced by the production method.

  Conventionally, as one method of manufacturing a mesh body having corners, as shown in Technical Document 1, first, a rhombus network is knitted by a Raschel machine or the like to form a mesh of the knitted mesh body. Along the legs, cut diagonally in a straight line and separate the triangular part into a square mesh form, and stitch each side of this square mesh into a shape and size according to the application, It was the target square mesh.

On the other hand, as described in Patent Documents 2 and 3, the bag-shaped square mesh is used as a sandbag or a stone bag used for civil engineering work such as revetment work. These sandbags and stone bags are knitted with a net by a Raschel machine, a knotless net or a crotch net, but all have a rhombus shape, and in particular, a net with a highly productive Raschel machine is often used. .

  However, when a bag-like square mesh is formed from a rhombus-like mesh body, first, as in Patent Document 1, the rhombus-like mesh body is knitted and the knitted mesh body is cut obliquely. Then, after obtaining the square mesh, it was necessary to overlap the two square meshes and stitch at least two sides into a single bag-like square mesh.

As for the conventional bag-shaped square mesh, as in Patent Documents 2 and 3, a rhombic mesh is formed into a bag shape by sewing, and gravel, stones, etc. are filled in this mesh bag. Due to the physical properties of the diamond-shaped knitting structure, the net expands in the weft direction, and the length in the warp direction is naturally shortened.

  The present invention, when producing a bag-shaped square mesh, allows the knitting machine to be integrally knitted on the knitting machine without stitching the square meshes together, and the degree of background obtained by separating unnecessary portions. It is intended to provide a bag-shaped square mesh with a low elongation rate.

  In order to solve the above-mentioned problems, the present invention uses a double needle row warp knitting machine to individually knit the front and rear nets with the front net forming knitting yarn and the rear net forming knitting yarn, Of the knitted wales constituting the part network and the rear network, the knitted wales that define a desired network body are connected and knitted in a slanting direction with connecting yarns to form a bag-like network body, and then connected and knitted. By separating the defined part including the outside of the part by cutting or the like, a bag-like net body having corners is manufactured.

  In the present invention, a bag-like net body composed of a front net and a rear net constituting a rhombus-like knitted structure including legs and knots is connected and knitted by a connecting yarn, and the net of the net is It is a bag-shaped square mesh formed with corners.

  According to the manufacturing method of the present invention, the bag-shaped square mesh having the square stitches formed in the rhombus-like knitted structure is knitted simultaneously with the knitting of the front network and the rear network. The desired bag-shaped square mesh can be easily obtained by separating the material by cutting or the like.

  In addition, the bag-shaped square mesh obtained by the manufacturing method of the present invention is a square mesh shape even though the bag-shaped square mesh is knitted with a rhombus-like knitted structure, so the object stored in the bag is a stone. In some cases, when the net is added with the weight of the stone to be stored, the vertical and horizontal dimensional stability and shape retention of the bag are improved, and the bag-shaped square mesh is less likely to be deformed during use.

  Furthermore, another bag-shaped square mesh obtained by the production method of the present invention is formed of a rhombus-like knitted structure for each knitted surface constituting the mesh cage in the formation of a rectangular parallelepiped mesh cage called a gabion. Since it is formed in double by a square mesh, by folding the developed net material obtained by separating the part that defines the mesh bag by cutting etc., by sewing a part of the bent part A robust desired gabion made of a square mesh can be obtained.

  The knitting needles that pass through the connecting yarns are jacquard hooks that can be controlled by jacquard, and the connecting knitting for each knitting wale forming the mesh is carried out by the individual connecting yarns, so that a bag-like net body is obtained. As a result, it is possible to freely select the connecting position in the front and back netting knitting, and as a result, the bag-like square netting having various square shapes can be obtained by the binding knitting at any position of the front and back netting. Can be organized.

  The knitting needles that pass through the connecting yarn are string bars formed by stretching a long body, and the connecting knitting for each knitting wale forming the mesh is threaded through a guide attached to the string bar. When the yarn is divided and formed into a bag-like net body, the movable width of the string bar through which the connecting yarn is threaded in the connecting knitting of the front net and the rear net is the same as that of the conventional guide bar. By taking it three times or more larger, it is possible to employ a minimum number of connecting yarns, and it is possible to maximize the width of the square mesh.

  By knitting the front mesh and the rear mesh with different meshes, it is possible to manufacture on the machine a bag-shaped square mesh having different density and shape of the corners.

  Since at least one side of the mesh body is open and the other side is knitted and knitted with a connecting thread, it has vertical and horizontal dimensional stability as a bag-shaped square mesh having a slot for stones, etc. Even when it is filled, it becomes a bag-shaped square mesh with good shape retention that does not deform the square.

  Since the meshes of the front mesh and the rear mesh are different, in the use of the bag-shaped square mesh in civil engineering work such as vegetation, it can be used as a composite having different meshes. Moreover, application as a sandbag is also possible by sewing.

  Next, embodiments of the present invention will be described with reference to the drawings.
