Embodiment Construction

[0046] Best way to implement the invention

[0047] The toothbrush manufacturing apparatus 10 is an apparatus for manufacturing a toothbrush 6 by filling the back surface of the substrate 3 with a resin 5 after inserting the bristle bundle 2 of the bristles 1 into the tufting holes 4 of the substrate 3 . The structure of the toothbrush manufacturing apparatus 10 includes a substrate forming machine, a substrate conveying device, a bristle tuft inserting device, a bristle tuft base melting device, and a substrate back filling molding machine.

[0048] In the toothbrush manufacturing device 10, the hair bundle inserting device 20 constitutes asfigure 1 - As shown in Fig. 3 , the stand 20A has a hair supply device 21, a hair bundle holder, holding and moving device 22, a sleeve, holding and moving device 23, and a hair bundle pressing device 24, and operates as follows.

Abstract

A manufacturing method of a brush 6 including of inserting bristles 2 into a bristles insertion hole 55, and thereafter implanting the bristles in a resin base plate. Further, each individual sleeve 60 is prepared in correspondence to cross sectional shapes and cross sectional areas in the bristles insertion hole 55, the bristles 2 are introduced to the sleeves 60, and each of the bristle 2 in the sleeves 60 is inserted to the corresponding bristles insertion holes 55 by an extrusion pin 71.

Description

technical field [0001] This invention relates to the manufacturing method of brushes, such as a toothbrush. Background technique [0002] As the prior art of the toothbrush manufacturing method, the method of using a metal member called a flat wire to insert the hair bundles of the used hairs into the hair bundle holes to fix them is widely promoted. The device structure of this mode is simple, but there are corrosion of metal, waste When forming a composite of metal and plastic, the thickness of the hair-planting part of the toothbrush cannot be reduced, the size of the hair-planting hair bundle is limited (the thick hair bundle cannot be implanted), and it is difficult to tilt the hair-planting and other unsatisfactory shortcomings. [0003] There are the following three methods as conventional techniques that do not use flat lines. [0004] (1) Type I: Special Fair 6-16725, USP4635313 [0005] The hair bundle is inserted into the hair bundle insertion hole of a forming ...
