  FIGS. 4 (a) to 4 (f) are diagrams for explaining paper brush bristles used in the segment brush of the present invention. It is made from a thin paper sheet 41 as shown in FIG. The paper sheet 41 is rounded from one end to form a round bar 42. The rod-like body 42 is in a twisted state 43 as shown in FIG. After twisting the rod-like body 42 obtained by rolling the thin paper sheet, the twisted paper brush bristles 44 are produced by further twisting.

  Since the twisted paper brush bristles 44 have a gap between twisting and twisting, they can absorb vibrations in addition to the softness and stiffness of the paper. In the case of Japanese paper, the paper sheet 41 is shaded (some places can be seen through). The paper sheet can be selected from various varieties depending on the surface to be polished or the purpose of polishing, such as Japanese paper, western paper, cardboard, recycled paper and the like. The paper sheet may be based on waste paper, milk pack, cardboard or the like.

  FIGS. 4 (e) and (f) are other examples of twisted paper brush bristles in which at least one of the twisted paper brush hairs is knitted by a knitting machine (known knitting machine). 45 is wound 45 '. For example, as shown in the figure (f), one of the wound meshes is attached to an attachment member 452 to form a paper brush having a mesh. The paper brush can have an end surface 451 or a side surface as a polished surface. From the synthetic resin brush bristles, it is possible to obtain paper-specific properties with a softer polished surface and lower back. There are many types of the paper, and the type of paper suitable for the purpose can be selected depending on the application when used as paper brush hair. The various paper sheets are twisted after rolling a thin sheet into a rod-like body.

  The twisted rod-like body has a unique softness resulting from the type of paper, a frictional force resulting from the twisting and twisting of the paper, and a unique strength due to these, and is stiff, and It becomes paper brush hair with excellent flexibility. At least one or a plurality of the twisted and twisted rod-shaped bodies are assembled into a paper brush hair. The highly flexible paper brush bristles are implanted in the implantation member.

  The twisted paper brush bristles are further knitted by a known knitting machine (not shown) as shown in FIG. In addition to the illustration, various known methods can be employed for the method of knitting the twisted and twisted paper brush hair. The paper brush bristles knitted in the net shape can use the tip, side end and side as brush surfaces. As for the method of knitting the net, the degree of polishing can be changed depending on the intersection, knot, size of the stitch, density of the stitch, etc., in addition to the paper material. Since the paper brush hair knitted in a net shape has more gaps than the case of twisting only, it can be polished while absorbing vibration in addition to soft polishing.

  Although not shown in the figure, the paper material rolled up, twisted, and rolled up soaks the adhesive throughout. The paper material rolled up, twisted and rolled is formed into a desired shape by a mold after the adhesive is dried. The twisted and brushed bristle material formed into a desired shape at the tip part is bundled into a paper segment brush. The paper segment brush has a unique softness on the polished surface, and is added with hardness by an adhesive, and has a unique strength as a segment brush.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to the said Example. The present invention can be modified in various ways without departing from the scope of the claims. The material, size, shape, density, etc. of the brush hair and the mixed substances can be arbitrarily selected. In particular, it is needless to say that well-known or well-known members can be used for the metal member, the synthetic resin member, the mixing member, and the adhering member other than those mentioned in the present specification.
