Description

one

The invention is intended for the manufacture of a web - a wire mesh of rings formed during the assembly process of wire spirals.

There are known methods for fabricating a wire mesh of woven rings, in which the first row of rings are formed by cutting the outermost turns from a series of parallel-lying spirals and reducing the ends of each turn, and the subsequent rows are obtained by interweaving the outermost turns of the spirals into every two rings, followed by their cut and converging ends.

According to the proposed method, in order to simplify the technology, after each row of rings are woven, the mesh web is moved reciprocally in the direction of the row rows by an amount equal to half the grid spacing.

In addition, in some cases, before each reciprocating movement of the mesh, it is turned 180 ° around an axis perpendicular to the direction of the row of rings.

FIG. 1-3, a diagram of the formation of the netting web by the proposed method is given.

The grid is made from a series of spirals 1 arranged in increments equal to the grid spacing. The spirals are turned one turn in a screw motion, the end of each spiral is woven into two adjacent rings of the finished row of mesh 2, after which the end turns of the spirals are cut along lines 3 and reduced to form a new row of rings. The grid is supported by the teeth of the comb 4 located at this time between the spirals 1. Next, the grid is intercepted, the comb 4 is brought in and the comb 5 is fed, the teeth of which enter the rings of the new row of rings. When intercepting combs 4 and 5 move obliquely and, moreover, along the upper row of rings and a half step. After interception, the operations described above are repeated to form the next row of rings.

Sometimes, during manufacture, the grid is placed on a row of fixed hooks 6 (Fig. 3) located at the same spacing as the comb, for the rings of the upper row collected in the previous cycle. Then, all the spirals 1 are turned by a screw motion one turn, while the ends of each spiral are engaged with two adjacent rings of the upper row of the finished part of the grid. The end turns of the spirals 1 are cut off and their ends are reduced, forming a new row of mesh rings, after which the grid remains from the hooks 6, turn it around the vertical axis by 180 ° and hang it on the hooks 6 on the new rings,

Claims (2)

1. A method of manufacturing a wire mesh of woven rings interconnected, in which the first row of rings are formed by cutting off the extreme coils from a series of parallel spirals and reducing the ends of each coil, and the subsequent rows are obtained by weaving the extreme coils of the spirals into each two rings with by their subsequent cut-off n by converging the ends, differing the fact that, in order to simplify the technology, after each row of rings is woven, the web of mesh moves reciprocatingly in the direction of the row of rings by an amount equal to half of the net of the net. 2. A method according to claim 1, characterized in that prior to each reciprocating movement of the web, the net is inverted by 180 ° around an axis perpendicular to the direction of the row of rings. 1 FIG. 2 FIG. 3
