Description

I

The invention relates to a device for the manufacture of four-piece knotted woven nets based on the principle of four-pinion gears.

A device is known for making four-strand non-nonshelle braided nets (GDR patent No. 43176, Cl. 25-111, 1968). It is constructed in such a way that for the manufacture of the network shoulders there are a large number of located near the heads of the weave, which consist of four winged gears, the middle points of which are located at the corners of the square (the principle of four gears).

On each of the four heads of the plaiting gears of the heads of the weave, fabrication of the shoulder of the net is carried out by moving four bobbins along the paths of figure eight arranged diagonally to each other (L

gu Winged gears have four grooves each, located right along the corner, for receiving and transporting the bobbins.

For the connection between adjacent shoulders of the net, there is a windrow winged gear of the crown: the heads of the weave are transitions through which the bobbins from one head of the weave are directed to the adjacent ones.

In connection with the location and number of winged gears on the principle of four-pinion gears and the construction of winged gears with four grooves, it takes eight steps or turns of 90 gears to make a node in the shoulder of the network.

However, the disadvantage is the division of the winged gear. The division of the wing gear into 4 slots at an angle of 90 determines the use of 4 DM

calling bobbins with a small capacity of coils.

 The purpose of the invention is to improve the quality of the products produced by improving their strength characteristics by reducing transitions. Figure 1 shows the weaving head and steps for making a braided strand in a network strand; Fig. 2 shows two adjacent braiding heads and steps for fabricating adjacent network strands; Fig. 3 shows two adjacent braiding heads and stages of making weave points between neighboring network strands.

In the upper part of the FIG, there is depicted a braided head 10, which is made up of four winged gears 11-14 located at the corner points of the square. Each top wheel has three grooves 15 located at an angle of 120 to each other. Every 15 times, 1 and 1 1-4 spindles are received and transported. The braided spindles 1 and 2 run around the ijo formed from wheel gears II and 12 TpaeKTOpKH in the type of eight, and the braided spindles 3: and 4 - along the figure-eight trajectory formed by gears 13 and 14.

Fig. 3 shows the fabrication of the intersection of two adjacent network strands. The initial position of the spindle spindles in this case corresponds to the initial position of the spindles of FIG. 2. The transition of braiding spindles from one braiding head to an adjacent one is carried out along trajectories in the form of a figure of eight, formed by winged gears. According to FIG. 3a, it is apparent that the manufacture of the binding sites ends at the end of the five stages and the sixth stage is already the first stage for the final production of the network strand.

Thus, the solution takes advantage of the principle of four-winged gears as compared to the principle of three-pinion gears — a small number of steps for making a node in the network arm — combined with reducing steps in manufacturing the junction from eight to five steps.

The advantage of the proposed device f is that for each winged gear only three slots are needed to receive and transport the bobbin (in the well-known principle of four-fold gears, four slots are needed on each gear wheel). Due to the low maintenance costs of each wing
