Description

A known method of making a netting on circular knitting machines by passing looping on selected needles of the machine. In order to pass the looping, they use the technique of twinning adjacent needles, etc.

According to the proposed method, the needles of the cylinder are placed with gaps in the knitting machines of round knitted machines with gaps in their places, and to enhance the effect, smooth and patterned presses are used in alternating systems, in the selected sequence. FIG. Figure 1 shows one of the possible options for the location of the needles in the cylinder for carrying out the proposed method; in fig. 2 shows another possible arrangement of the needles in the cylinder of the same machine, and in FIG. 3-6 schematically show the relative placement of the needles of the cylinder relative to the presses of the machine’s loop-forming systems during the process.

Inserts are inserted into the machine cylinder with two or one needles in different sequences. There are many variations of alternating tiles with two needles with tiles with one needle, which changes the appearance of the web. For example, two options are shown:

1. Four tiles with two needles and two tiles with one needle on the right side. This arrangement is shown in FIG. one.

2. Four tiles with two needles, one tile with one needle on the right side, one tile with two needles and one tile with one needle on the left side. The alternation of the needles is shown in FIG. 2

To achieve the best effect, a smooth weave alternates with a press weave, for example:

a) a system with a smooth press alternates with a system with a figure press;

b) after two systems with figure presses, one system is installed with a smooth press.

The effect of interlacing is achieved by the appropriate installation of curly presses with respect to each other and with respect to needles.

Of course, these examples of the grid do not exhaust the possibilities of getting the other effects of the mesh on the machine.

The approximate location of the needles around the circumference of the cylinder and the installation of shaped presses with respect to the needles are shown in FIG. 3, on which dots correspond to needles, crosses indicate the absence of needles, Arabic numerals affixed above the needles to the left, correspond to the number of needles and the width of the rapport, and deep and shallow grooves underneath and opposite the needles correspond to the same grooves around the circumference of the press . The notches show the installation of curly presses with respect to each other and with respect to the needles.

For positioning the machine elements of FIG. 3, where rapport is equal to eight needles, the number of needles on the machine should be divisible by 8 without a residue. The number of systems is a multiple of three, since after every two-piece systems with figured presses there should be one system with a smooth press. The alternation of deep grooves with shallow ones on figure presses refers to 3: 5, i.e., after three deep notches, five shallow ones.

For the mesh produced when the machine elements of FIG. 4, the number of needles on the machine should also be divided by 8 without a residue. The number of systems on the machine is a multiple of three. After every two systems with shaped presses followed by one system with a smooth press. The alternation of deep grooves with shallow ones on figure presses refers to 4: 4, i.e., after four deep grooves, four shallow ones.

According to FIG. 5 the number of needles on the machine should be divided by 6 without a residue. The number of systems on the machine is a multiple of three. After every two systems with shaped presses followed by one system with a smooth press. The alternation of deep grooves with shallow ones on curly presses is 3: 3, i.e., after three deep grooves, three shallow ones.

For the arrangement of the machine elements, but FIG. The number of needles on the machine should be divided by 12 with the remaining 6 needles. The number of systems on the machine is a multiple of three. After every two systems with shaped presses followed by one system with a smooth press. The alternation of deep grooves with shallow ones on figure presses refers to 3: 3, i.e., after three deep grooves, three small ones.

Subject invention

A method of producing a netting on circular knitting machines by passing looping on selected needles, characterized in that the needles of the cylinder are placed with gaps in places of which the web, the same and figured presses are installed in the sewing systems in alternating sequences.
