Description

Technical Field [0001] The present invention relates to a continuous loop fiber mat forming edge adjustment device,

The present invention relates to an edge aligning apparatus for continuous loop fiber mat forming, and more particularly, to a method of aligning both side portions (both edges) of a core strand sheet fed to form a continuous loop fiber mat, And to provide a new continuous loop fiber mat forming edge aligning apparatus capable of ensuring evenness of unit weight of each fiber mat.

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.

In order to solve such a problem, a plurality of rows of yarns are supplied to a conveyor, and a plurality of rows of yarns are scattered to be arranged on the upper surface of a conveyor to form a core strand sheet. A core strand sheet The binder is fed into the space between the surface of the core strand sheet and the disturbed yarn in a plurality of rows and then the block forming sheet fed with the binder into the core strand sheet is put into the oven, It is necessary to adopt a method of forming a continuous loop fiber mat integrally bonded.

At this time, when the core strand sheet is conveyed along the conveyor, the yarn of the core strand sheet escapes to both side portions (both edges) of the conveyor to cause loss of material (i.e., loss of yarn and binder) There may be some obstacles to ensuring the uniformity of the weight per unit area of the loop fiber mat.
