    Previous attempts to cut or trim a wet, non-woven, fibrous mat using a fluid jet have been largely unsuccessful, particularly when the mat contained reinforcing strands. The present invention overcomes this problem by using a fluid jet located below the mat in combination with a fluid jet set at an angle above the mat.

    FIG. 1 shows a device for producing a nonwoven fibrous material; in fig. 2 - a device for cutting material edges, front view; in fig. 3 - the same, side view.
    An aqueous fibrous suspension, for example, a suspension of glass fibers in water, is prepared in mixer 1 and pumped into tank 2 via a pipeline (not shown). This suspension is then pumped through the pipeline 3 under high pressure into the hydraulic template 4, where the suspension is spread in a layer over the surface with holes 5, for example, on the mesh surface of the conveyor 6. The suspension is sucked through pipes 7, which suck water through the surface of the conveyor 6 , leaving a raw mat 8 of randomly interwoven fibers on the upper surface of the conveyor 6. Water sucked into the pipes 7 using a vacuum source (not shown) enters the collection tank through pipelines (not shown) for lneyshego jo use it in a mixer to prepare a new suspension.
    The raw fiber mat 8 is transferred from the conveyor 6 to the second belt 9, which can be made of an identical material and identical to the conveyor 6 of the design. Both tape 9 and wet mat 8 move in the direction shown by the arrow; Kami (Fig. I) are passed through a set of rollers 10 through a resin bath 11 to soak the raw mat 8 with a binder resin. The mat 12 impregnated with the binder is then transferred from the belt 9 to the third conveyor belt 13. The mat 12 that is impregnated with the binder is transferred through the dryer where all remaining material on the mat and in the binder is removed, and the resin in the binder vulcanized.
    The raw mat 8 is cut after it leaves the hydraulic template 4 before it is transferred to the second conveyor belt 9. As a result of using one or two trimming devices 14, one or both edges can be cut. The edge of edge 15, which is separated from the main part of the mat 8 using the trimmer 14, is not transferred. on the second conveyor 9, and is sent to the waste return bin 16, where it disintegrates into parts using a pump 17, and then is pumped to the slurry tank 2 through conventional pipelines (not shown). Previously, the return bin 16 wastes and 50 lasos 17 were used to reuse when f -; changes in the whole mat 8 at the beginning of operation 7 of the entire system or during periods when the quality of the mat 8 did not meet the requirements for any reason. When removing the edge of the edge 15 in its wet state and before, the binder is added and cured substance, this edge is recyclable. Ready mat requires

    Most of the cases are only very narrow edging in order to obtain a sharp and even edge.
    The trimming device 14 (FIG. 2) comprises a collector assembly 18, a nozzle installation assembly 19, and a mounting assembly 20. The collector assembly 18 is typically a V-shaped collector, one of whose elbow 21 passes over the surface, with openings or conveyor belt 6 , the other elbow 22 is under the belt, and the connecting part 23 connects both elbows at the edge 24 of the conveyor belt 6. The collector (Fig. 2) can be made of a conventional pipe and pipe fittings, however it can be of any conventional design.
    At the end of the upper elbow21, a nozzle 25 is installed, in which a distributor of a jet of liquid is replicated. For example, nozzles 26, so that the central line of the nozzle is located node angle relative to the vertical. Angles may be different, however, an angle of 45 ° to the vertical is most appropriate. The nozzles are oriented so that the outgoing jets from it are directed downwards and to the edge 24 of the conveyor belt 6. At the end of the lower elbow 22, a nozzle 27 is fixed, in which a liquid distributor, for example nozzles 28, is installed, so that the central line of the jet emitted from it is vertically.
    The nozzles 26 and 28 may be identical and preferably have a round hole with a diameter of usually about 3.57 mm through which a jet of liquid is emitted. The collector has such a construction and the nozzles are located so as to position the central lines of the two jets emitted by the nozzles 26 and 28, crossing them at point 29. The latter is located above the upper surface of the conveyor belt 6 and preferably at a distance of about 6.35-12.7 mm from its upper surface.

    The collector assembly 18 is connected to a high pressure fluid source that contains known equipment, such as city water, a high pressure pump connected to a water source, etc. (kg / cm). This system preferably also contains a conventional pressure regulator which allows the pressure in the collector assembly 18 to be adjusted to the desired value. In the preferred embodiment, the fluid used to power the collector assembly 18 is removed from the waste return bin 16, filtered to remove any solid material, including fibers that contribute to the flow of fluid through the nozzles 26 and 28, and is fed through a conventional high pressure pump the manifold pressure torus. The manifold has a means for longitudinal displacement of the manifold to the desired position and is held there by means of an assembly. The frame 30 consists of a mortise frame element 31 and a lower frame element or channel 32. The latter has a 33 slot on the bottom side, which provides horizontal movement of the nut 34. Channel 32 surrounds the carriage 35, which covers the upper elbow 21 of the collector assembly 18 with a conventional clamp 36 . On the bottom surface of the carriage 35 there is a groove in which a nut 34 is placed, mounted on the surface 37 of the clamp 36. In the central part of the box-shaped channel 32 along its entire length there is a spindle 38. At one end the spindle 38 enters the hole 39 in plate 40, which is part of the main frame 30. The other end of the screw 38 passes through the holes in the plates 41 and 42, which are also parts of the main frame 30, and rests on the sub-plate 43 attached to the plate 42. The screw 38 passes through the sub-plate 43 so that an asterisk 44 is fixed at its protruding end. Another asterisk 45, preferably of smaller diameter than the asterisk 44, is attached to the flywheel 46 and installed with it by means of a conventional hub (not shown) and a shaft 47 attached to the plate 42 by means of a nut 48 . While rotating the flywheel 46 rotates link: zdorochka 45, which by means of chain 49 transmits the rotation of the sprocket 44 and the spindle 38: The nut 50 is screwed onto the spindle 38 and attached to the nut 34. The rotation of the shaft 38 causes the nuts 50 and 34 to move transversely along the screw 38 in the direction dependent From the direction of rotation of the screw 38. As the nut 34 transversely moves, it pushes the carriage 35 in the transverse direction, which sets the nozzles 26 and 28 relative to the edge 24 of the conveyor belt 6. To improve the glide of the carriage 35 through the channel 32, the top and sides can be lubricated . The collector assembly 18 and the nozzle adjusting assembly are installed by means of the mounting assembly 20, which contains a mounting plate 51. The latter can be attached by any suitable means to any frame. Plate 51 can be fixed by welding or bolts 52. A bracket 53 is rigidly attached to the central part of the plate top 51, in which a hole 54 of sufficiently large diameter is made to pass through it and without sticking the cut bolt 55. The bolt 55 is screwed into an eye or bracket 56 which is rigidly attached to the upper central part of the plate 57, which has a large notch 58, which serves to accommodate the lower end of the bolt 55 and the end part of the mounting bracket 59. Perpendicular to the plate 57, the bracket 59 is welded, which can cross section. The other end of the crown 59 is rigidly attached to the first 60, to which the second plate 62 is bolted by means of bolts 61, having three longitudinal grooves 63 in the extended koytsb. The second plate 62 is screwed to the upper frame element 31, preferably with three bolts 64. The grooves 63 allow a small transverse adjustment of the collector node 18 and the nozzle adjustment assembly 19 with respect to the conveyor belt 6 in order to compensate for any installation errors. When the nozzle adjustment unit 19 is in the desired position, the bolts of §4 are tightened, thereby locking the nozzle adjustment unit in the fixed position of the conveyor belt pippere 6. The plate 57 is fixed with the bolt 55 and the bolts 66 passing through the grooves 65 in the plate 57 and screwed in the plate 51. In order to correct any mounting errors in the vertical installation of the nozzle adjustment assembly 19 and the collector assembly 18, the bolts 66 are released and the plate 57, having vertical grooves 65 long enough to make an adjustment of 12.7 m m. are installed in the proper vertical position by rotating the bolts 55 in the required direction so as to install the nozzles 28 and 26 in the required position relative to the conveyor belt 6. After the nozzles 28 and 26 are installed in the required position, close the bolts 66, and the nut 67 is pulled to the bottom of the bracket 53 to prevent the bracket 56 from moving upward.
