The invention relates to equipment for processing composite materials and can be used in various sectors of the national economy for the manufacture of mesh structural elements, non-metallic reinforcing mesh for concrete, polymer concrete, etc. products.

The purpose of the invention is the expansion of technological capabilities and improving the quality of manufactured products.

FIG. I shows the device, side view; in fig. 2 - the same, top view; in fig. 3 - section AA on. FIG. 2; in fig. 4 shows a pattern for laying and moving transverse threads at the ends of the conveyor; in fig. 5 - the structure of the fiberglass mesh, obtained by laying the transverse filaments on the longitudinal.

The device includes a stationary shpulnik 1, an impregnation bath 2, a conveyor 3, a wrapper 4, a polymerization chamber 5, t needles 6, a cutting tool 7. The conveyor 3 and a wrapper 4 are set in motion by means of leading sprockets 8 and 9 through corresponding gears 10 and 11 from a single drive 12. The winding machine 4 transverse threads is perpendicular to the conveyor 3. The thread guide 13 of the wrapper 4 is fixed to a cantilever and when rotating the latter makes a movement in a plane perpendicular to the conveyor 3, and around it along a path equidistant to winding ontura 4. Thread guide 3 possibility of axial movement for adjusting its position relative to conveyor 3 (Fig. 4).

Conveyor 3 consists of two chain loops 14 (Fig. 1), to the links of which metal plates 15 are attached (Fig. 3) with fluoroplastic linings 16. For better contact of the transverse filaments with the longitudinal contours, 16 have

The outlet form, the conveyor is located at the base 17.

The ends 18 of the pads 16 are provided with holes 19, into which spring-loaded locking pins 20 are inserted, allow them to sink into the holes 19 when moving the stop 21 relative to the cam 22 and return to their original position under the action of spring 23. The threads are longitudinal in orientation before laying The conveyor 3 passes through the impregnation bath 2 and the thread guide gels 24. The transverse orientation threads after the impregnation bath 2 pass through. Central niten and ruler 25, and then 4 reed yarn feeder 13 of the wrapper 4 to the trans-Yorter 3.

G Device, works as follows.,

I From the blade 1, the longitudinal thread system is charged through the impregnation bath 2, the thread guide 24 on the conveyor 3 and evenly placed on its surface. The transverse yarn system from the spool box 1 is grouped into one thread And through the impregnation bath 2 and the fixed central thread guide 25 is threaded through the yarn feeder 13 from winding 4: and fixed on fixing tabs f f x 20 of the conveyor 3. From With the help of the driver, I and 12 and the 10 and 11 transmitters transmit: with rotation, respectively, of the leading stars, 1 daughter 8 and 9 of the conveyor 3 and the wrapper 4. As a result, the yarn feeder 13 rotates, forming a system of transverse threads around the moving conveyor 3 with longitudinal threads . Buttress threads are placed on the upper and lower branches of the conveyor 3 between the pins 20 installed on the ends of the pads 16. When the conveyor is moving. The 3 turns of the transverse threads go from a vertical position to a horizontal one, in which case their tension occurs, which is; the swarm can be adjusted by extension; yarn feeder i3 on the winding 4 towards the conveyor 3, as well as changing the diameters of the driven sprockets 26 of the conveyor 3 (Fig. 2 and 4). The predetermined tension in the transverse threads is maintained throughout the conveyor's path until the end of the binder polymerization process.

The required tension of the longitudinal grid lines is created and adjusted by known means, both before they enter the impregnation bath 2 and after it 5. The final structure of the formed mesh and its geometrical parameters depend on the ratio of the speeds of movement of the wrapper 4 and conveyor .3, as well as on the schita of the longitudinal threads.

After the two filament systems are superimposed on each other, the resulting mesh with the help of conveyor 3 enters the polymerization chamber 5 {Fig. I and 2), at the exit of which the stops 21 of shtyry 20 interact with the deflecting copiers 15 22, as a result of which the plugs 20 drown in the holes 19 of the pads 16 and do not prevent the removal of the grid from the conveyor 3. After These grids, stops 21, come off copiers 22 and pins 20 under the action of the spring 23 to return to their original position. The rolls 6 feed the grid to the means 7, where it is cut into blanks of the required length, the finished products are picked up by the means 27 and placed in a container 28.

2t; Thus, the device allows to form in the continuous mode a high-quality fiberglass mesh of longitudinal and transverse threads with different patterns of their interlacing.
