In general, glass fiber (glass fiber) mats are used in a variety of applications such as liquid or gas phase separators, thermal insulation, low temperature insulation, and insulation. Glass fiber mats can be made from glass fibers (or glass fiber strands). The process of making glass fiber strands from molten glass generally involves thinning the fibers from the small openings of the equipment operably connected to the glass-melting furnace. The extruded glass fibers are formed into a desired diameter and thickness (generally by mechanical means) and are collected or directly molded into a mat.

The production process of glass fiber is made by blending the raw material (powder form), melting it at a high temperature of 1500 ° C or higher, passing it through a hole called a bushing (it is called a spinning process) and winding it with a high speed winder to produce fiber. At this time, the thickness of the fibers and the strands of the fibers are constituted.

The production of continuous glass fiber mats, which have been commercialized at present, is produced by pulling a yarn at a high speed without sensing the yarn during the above-mentioned glass fiber spinning process and directly scattering a certain amount per unit area on the mesh. It is a method that can not be produced without having a spinning facility that produces fibers. The production of spinning mills is not diversified because huge funds have to be invested in order to construct the spinning mills.

The yarn 10 wound on the feeding bobbin in the form of a failure is fed toward the conveyor 30 (belt of the conveyor 30). The yarn 10 is glass fiber. The feeding bobbin is connected to a motor shaft of the motor through a power transmission means (pulley, belt, etc.), and a feeding bobbin is rotatably mounted on a frame (not shown) So that the feeding bobbin is rotated by the motor shaft of the motor so that the yarn 10 is fed to the conveyor 30 side. Alternatively, the yarn 10 is wound on the feeding bobbin in the form of a failure so that the yarn 10 is wound on the winding roll at the end of the supply line of the yarn 10, and the yarn 10 is pulled by rotating the winding roll, (10) may be supplied toward the conveyor (30). In the present invention, the feeding roller is arranged in a plurality of rows in the left and right width direction perpendicular to the longitudinal direction of the conveyor 30 so that the yarn 10 is fed to the conveyor 30 side by a plurality of rows. In the present invention, the yarn 10 is fed to the conveyor 30 in five to six rows. The yarns 10 (glass fibers) fed into the plurality of rows can be fed into the respective feeding sleeves arranged in a plurality of rows and then fed to the conveyor 30.

The yarns 10 (glass fibers) in each row passing through the feeding sleeves pass between two Travis rolls 20 arranged in a pair. The two Travis rolls 20 are arranged in the transverse direction orthogonal to the lengthwise direction of the conveyor 30 and a plurality of rows of yarns 10 are passed between the two Travis rolls 20.

The traverse roll 20 is moved (reciprocated) in the transverse direction orthogonal to the longitudinal direction of the conveyor 30 when the yarn 10 of each row passes between the two trav-rolls 20 in the travicing stage of the yarn 10, So that the yarn 10 in each row is supplied in a disordered state on the conveyor 30. In the present invention, two Travis rolls 20 are rotatably mounted on the frame, the frame is movably mounted in a lateral direction orthogonal to the longitudinal direction of the conveyor 30, and the frame is connected to the piston rod of the cylinder Or a ball screw nut provided in the frame may be connected to a ball screw provided on the motor shaft of the motor. Therefore, as the piston rod of the cylinder expands and contracts, the frame and the Travis roll 20 mounted thereon can be reciprocated (traversed) in the lateral direction of the conveyor 30, and the ball screw rotates The ball screw nut mounted on the frame moves along the ball screw and the frame and the traverse roll 20 mounted thereon can be traversed (traversed) in a direction perpendicular to the longitudinal direction of the conveyor 30. [ It is also possible that one of the two Travis rolls 20 is mounted on the frame so that only one traverse roll 20 is reciprocated in the transverse direction of the conveyor 30. [ All of the reciprocating means capable of reciprocating the traverse roll 20 in the lateral direction of the conveyor 30 can be employed.

The yarns 10 in the respective rows are supplied in a state of being disturbed rather than being supplied in a straight path and supplied onto the conveyor 30 in such a manner that the yarns 10 of the respective rows are entangled with each other when viewed from above the conveyor 30. Figs. 1 to 3 conceptually show that the yarns 10 of each row are fed on the conveyor 30 in a disordered state, and Fig. 4 is a schematic view showing that the yarns 10 of each row are fed 10C is a photograph showing the core strand sheet 10CS. In the present invention, it is important to supply the yarns 10 of each row in a disturbed state at the stage of traversing the yarn 10 to form the core strand sheet 10CS.

A plurality of rows of yarns 10 are supplied on the conveyor 30 in a disturbed state to form a core strand sheet 10CS by aligning rolls 60 on both sides of the conveyor 30, So that the yarn 10 is prevented from being lost due to sideways movement of the conveyor 30. In this case, since the loss of the yarn 10 is reduced and both ends of the core strand sheet 10CS are uniformly aligned without being escaped from the conveying path, the work for making the continuous loop fiber mat 14 becomes more smooth.

The binder 13 is fed onto the core strand sheet 10CS (core yarn 10 sheet) supplied with the yarn 10 of each row disturbed over the conveyor 30 in the supplying step of the binder 13.

An oven 50 is provided on the conveying path of the conveyor 30 and a binder supply part 40 is provided in front of the oven 50 so that when the former loop fiber mat passes into the oven 50, The binder 13 is melted by the heat of the oven 50 so that the liquid binder 13 is attached to the surface of the core strand sheet 10CS and the space between the core strand sheets 10CS is filled with the binder 13, The continuous loop fiber mat 14 comes out from the continuous loop fiber mat. The continuous loop fiber mat 14 in which the core strand sheet 10CS is integrally joined is formed inside the binder 13. That is, the continuous loop fiber mat 14 has a structure in which a plurality of yarns 10 are entangled and embedded in the binder 13 and integrated with the binder 13. At this time, the belt of the conveyor 30, which is the constitution of the conveyor 30, is made of a metal material, so that the belt of the conveyor 30 is not melted when the belt of the conveyor 30 passes through the oven 50.
