A spinning machine 1 composed of a melting furnace 11 for producing long fibers (glass fiber yarn) and a wet dryer 12 for drying the manufactured long fibers at a constant humidity, and a plurality of long fibers located at a lower part of the spinning machine 1 Winding machine (2) to wind the wound, the cutting machine (3) to cut the glass fiber layer wound on the winder (2), thin by pulling the glass fiber layer cut as described above one by one and pulling it back and forth and left and right A tensioner (4) for manufacturing a glass fiber plate, an adhesive material applicator (5) for adhering the long fibers (G) as a raw material by applying an adhesive material to the upper and lower portions of the glass fiber plate produced through the tensioner (4), and an adhesive material A long fiber mat manufacturing apparatus comprising a dryer 6 for drying the coated glass fiber plate with hot air; It is made of a short fiber layer coating apparatus for coating a short fiber mat on the upper and lower surfaces of the long fiber mat prepared as described above.

Therefore, when manufacturing the glass mat through the device configured as described above, the glass is put into the melting furnace 11 and then melted to produce a plurality of long fibers and at the same time cooled to a constant humidity and discharged to the bottom Then, after the long fibers discharged to the bottom is completely solidified, it is wound on the winding rolls 21 moved to the left and right to form a plurality of glass fiber layers, and then wound on the winding rolls 21 in multiple layers. The glass fiber layer is cut in the transverse direction through the cutting machine 3 to take out the rolled glass fiber layer one by one, and then the traveling direction and both sides are stretched through the developing device 4 to produce a thin glass fiber plate, and the developed glass The long-fiber mat is primarily manufactured by applying an adhesive to the upper and lower parts of the fiber board and performing hot drying.

Thereafter, the long fiber mat is introduced into the short fiber layer coating apparatus to coat a short fiber layer on the upper and lower surfaces of the long fiber mat, thereby completing a glass mat.

Thus, the present invention is an improvement of the short fiber layer coating apparatus constituting the glass mat manufacturing apparatus configured as described above, first, the configuration of the coating apparatus of the present invention with reference to Figs.

Long fiber mat (JM) is supplied from the front and the first upper, lower conveyors (73, 71) and the first lower conveyor which is moved through the drive unit 711, a plurality of rollers (R) and tighter (T) Located on the front of the 71, the bottom layer applicator 72 is applied to the upper surface of the first lower conveyor 71, the wet coating material mixed with short fibers and adhesive material, and located above the upper conveyor 73 And a top layer applicator 74 for applying a wet coating material mixed with short fibers and an adhesive to an upper surface of the upper conveyor 73, and mounted on one side of the first upper and lower conveyors 73 and 71. 761 and a coating part 7 composed of a plurality of rollers R and a second upper and lower conveyors 77 and 76 which are moved through the tightening machine T;
