Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brush material for polishing or cleaning rolled steel plates and the like.

A coated brush material in which a synthetic resin wire material containing abrasive grains is used as a core material and fine fibers are wound or braided around the core material has the expected effect of combining the abrasive action of the core material and the cleaning action of the coating. It has been known.

It has been known for a long time that the core material is made of a single wire material or a bundled wire material, and round wire materials are commonly used as the shape of the wire material.

If the core material is a single wire, a round wire may be used, but if the core material is a bundled wire, the wires tend to roll, collapse in clusters, and twist, which may disrupt the alignment of the wires and damage the coating. There is a possibility that the shape may become irregular in the length direction. As a result, uneven gaps and play occur between the round wire rods, resulting in poor adhesion of the coating,
In addition, unevenness may be formed on the surface of the coated brush material, which may cause the fiber coating to break. Furthermore, because the outer shape of the core material is circular, sufficient effects cannot be obtained, especially in heavy grinding.

Accordingly, the present invention provides a coated brush material having a wire assembly as a core material, in which a wire rod having a substantially rectangular cross section is used as the core material, and the wire rods are assembled so that the rectangular sides are in parallel contact with each other to form the entire core material. By arranging the outer shape so that it is rectangular in cross-sectional view and applying the coating, misalignment of the wire assembly serving as the core material, play between the wires due to this, poor adhesion of the fiber coating, and defective shape can be avoided. To provide a coated brush material that effectively solves these problems, allows each wire assembly to work soundly as a core material for polishing, and allows the coating to properly exhibit the focusing and cleaning effects of the wire assembly. It is something to do.

Furthermore, the present invention provides a coated brush material in which the brush planting density is significantly increased, the rectangular sides of each wire assembly exhibit a good grinding effect, and the coated brush material has an excellent heavy grinding effect.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the figure, 2 indicates a synthetic resin wire constituting the core material 1, and 3 indicates a fiber coating.

The wire rods 2 have a substantially rectangular shape in cross section, and the core material 1 is formed by gathering the wire rods 2 such that their rectangular sides 2' are in close contact with each other and aligned in parallel. The outer shape of the core material in the wire assembly is approximately rectangular in cross-sectional view. Preferably, the outer shape of the wire rod 2 is approximately square in cross-sectional view so that each rectangular side can be assembled under the same conditions.

As a wire assembly form that satisfies the above requirements, there is a form in which four rectangular wire rods 2 are assembled so that their rectangular sides 2' are in close contact with each other as shown in Fig.
As shown in B, a six-piece set or nine-piece set, etc., in which three pieces are arranged in two or three rows, is planned.

Each wire rod 2 is cut by rounding the four corners, etc., and a narrow tubular gap 4 is formed in the center of each four wire rod unit by opposing corner cuts 5 in the longitudinal direction of the brush material.

As shown in FIGS. 1 and 2, the wire assembly 2 is made entirely of abrasive grains, or as shown in FIG. Smooth wire material 2 that has a gentle abrasive effect without
Combined with b. Depending on the implementation, the wire rod 2b may be a metal wire.

When combining abrasive-filled wire rods and sliding wire rods, they are arranged in parallel so that they are alternately arranged.

The wire assembly 2 arranged in parallel as described above is used as a core material 1 and is covered with fine synthetic resin fibers.

By forming the corner cuts 5, the outer corners of the core material 1 are also cut off, and therefore the fiber coating 3 is also coated to conform to the corners, and no edges are formed at the corners of the coating 3.

As the coating form of the fiber coating 3, a braided coating or a coiled coating can be applied. It is optional to heat set or coat the fiber coating 3 with an adhesive. It is also possible to fuse the outer surface of the fiber coating 3 and leave an unfused fiber layer in the inner layer.

The coated brush material as described above is suitable as a material for a roll brush for polishing or cleaning.

In other words, in the wire assembly which is the core material, each wire is closely aligned on the rectangular sides, and there is play in the arrangement and collection of the wires.
Prevent rolling, collapse, or twisting as much as possible.

The outer shape of the core material made of assembled wire rods exhibits a regular rectangular shape, as if a single wire rod was used, and therefore the fiber coating is made in an orderly manner, and the outer surface of the coating is not twisted or uneven, and has a uniform outer shape. We can provide the best brush materials. Further, the wide brush material required in the market can be freely formed by increasing the number of rectangular wires arranged in a row.

In addition, since the covered brush materials as described above can be arranged with their rectangular sides parallel to each other to form a brush bundle, the number of brushes per unit area can be reduced when forming a disc brush or a roll brush. The density can be increased significantly. In addition to the improvement in planting density, each rectangular side of each wire assembly serving as the core material exhibits a good grinding effect, and a brush material particularly excellent in heavy grinding effect can be provided.

As a result of the above, the collective effect of the wire assembly in the coated brush material, which could not be fully utilized with the collection of round wire materials, such as the stiffness of the core material, the polishing or cleaning effect, etc., can be fully exerted. In addition, the fiber coating can be made healthy and its wiping effect can be properly exerted.
