Description

  The present invention relates to a brush assembly with a soft touch and a high cushioning property, and a method for manufacturing a brush. The present invention relates to a brush material and a brush assembly having a soft touch and cushioning properties by taking air into the brush material and the brush assembly, and a method for producing the brush.

Conventionally, a mirror polishing tool for polishing a hard surface, for example, as described in Japanese Utility Model Publication No. 6-18781, after weaving a wire made of ultrafine stainless steel wires, a pair of cut ends are arranged on the inside. The other pair of end portions are also folded inward, and then a core member is fitted into the channel member to produce a brush. Since the brush does not have a portion having a cut surface at the end, the surface of the material to be polished can be uniformly polished.
Japanese Utility Model Publication No. 6-18781

  However, in recent years, it has become necessary to polish surfaces such as liquid crystal, glass, and resin. Examples of the material for polishing the soft surface include a sponge and a buff material. Further, since the conventional brush is polished by a machine, there is a case where an impact is applied when hitting a material to be polished. No brush device has been developed that takes into account the problem of contact between the brush and the material to be polished. A material having a soft surface, such as a sponge or buff material, was inserted into the channel member, and then a core member was fitted into the bent portion of the material to form a channel brush. The fitting of the core member has a disadvantage that it has a balance with a brush, a channel member, and a core member, requires skill in assembling work, and takes assembling time.

  In order to solve the above-described problems, an object of the present invention is to provide a brush assembly and a method for producing a brush that are soft and take cushioning properties into an object to be polished having a soft surface. It is another object of the present invention to provide a brush assembly and a method for producing a brush that can be easily and quickly performed when a soft and cushioning brush is incorporated into a channel member.

  According to the present invention, when a soft and cushioning brush is incorporated into the channel member, if the two-folded portion is hardened by the resin member, this portion is welded to the channel member by heating, so that the core member is unnecessary. Can be assembled easily and quickly.

(First invention)
The brush assembly of the first invention is made of at least one soft material of woven fabric, non-woven fabric, foamable rubber member, natural fiber, synthetic fiber, and rubber-based member. A unit brush woven twice inside, a resin member in which a central portion of the unit brush is hardened, and a channel member that fits the resin member portion. The said raw material can be made into desired hardness by individual or mixing a woven fabric, a nonwoven fabric, a foamable rubber member, a natural fiber, a synthetic fiber, and a rubber-type member. The rubber material may be either natural rubber or synthetic rubber.

  The unit brush includes a first folded portion in which both side end portions of the soft material formed in a planar shape are folded inwardly, and a second folded portion in which upper and lower end portions of the first folded portion are folded inwardly. And a folded portion. The first folding portion is folded with both longitudinal end portions facing inward. In addition, the second folding part is folded inward so that both ends of the first folded part are perpendicular to each other.

  In the unit brush, the central portion in a state where the first bent portion is formed and / or both end portions in the state where the central portion and the second bent portion are formed are solidified by a resin member harder than the material. In the brush, at least one of the unit brushes is fitted to the channel member in the resin member portion. The channel member and the resin member of the unit brush are welded to each other by heat.
