FIG.8is a perspective view of a first embodiment of a method for manufacturing a mascara brush according to the present invention. InFIG.8, the method will be described by using the brush rod11of the first embodiment. As illustrated InFIG.8, the method for manufacturing a mascara brush comprises the steps: (a) forming a certain pattern of filaments151by attaching the filaments151to an adhesive tape14; (b) inserting the certain pattern of filaments151into the slot12; (c) forming a brush15by injecting an adhesive into the slot12or vibration-fusing or thermal-fusing the slot when the certain pattern of filaments151are inserted into the slot12; and (d) cutting and removing the portion attached with the adhesive tape14from the brush rod11formed with the brush15. In step (a) illustrated inFIG.8A, first, the filaments151are arranged to have a certain pattern to form the brush15. Generally, the arrangement of the certain pattern of filaments is formed on a lower adhesive tape, and then an upper adhesive tape is attached on the top of the filaments when the arrangement is completed to fix the shape of the filaments151. Next, in step (b) illustrated inFIG.8B, the certain pattern of filaments151are inserted into the slot11-3of the brush rod11. The certain pattern of filaments151inserted into the slot11-3are fixed into the slot11-3. The interval of the slot11-3is formed to about 0.1 mm to 1.5 mm. Next, step (c) ofFIG.8Cis a step of fixing the filaments151inserted into the slot11-3. To fix the filaments151, the slot portion is fused by injecting an adhesive into the slot11-3or using a vibration fusing machine20or thermal fusing machine20. The vibration fusion includes ultrasonic fusion or high-frequency fusion. Accordingly, the filaments151are fixed to form the brush15. In the case of the adhesive, there is no problem that the material is different, but when the vibration fusion or thermal fusion is performed, it is preferable that the brush rod11and the brush15are made of the same material. This is because different frequencies or heat are applied during vibration fusion or thermal fusion. In the embodiment, the brush rods11,11′, and11″ ofFIGS.1to5may be used. As illustrated inFIGS.2and4, even when the slots11-3a,11-3b,11-3a′,11-3b′,11-3a″, and11-3b″ are formed in a multilayer, since the certain pattern of filaments151are inserted, the vibration fusion or thermal fusion is performed in the same manner. Step (d) ofFIG.8Dillustrates a step of removing the adhesive tape14portion from the brush rod11. When the adhesive tape14portion is removed, generally, one side is formed in a shape tapered toward an end when the filaments are prepared, but the other side is cut by a cutter so that the end may not be tapered. However, since the both ends of the brush have different shapes, the tapered portion of the original end may be used to apply the mascara finely and the portion with the cutting surface may be used to apply a large amount of mascara, and thus there are various advantages and there is an advantage of forming a different shape of brush. Next, step (e) illustrated inFIG.8Emay further include a step of cutting the end of the brush in a certain form to form a certain shape of cutting line15-1on the end of the brush15when the brush15is fixed and adhered to the brush rod11. The cutting line15-1may be variously formed in the form illustrated inFIG.11. Further, a curling may be formed without cutting the end. In addition, curled filaments may be used, and such a use may be only a simple design change in the art to which the present invention pertains.

FIG.9illustrates a second embodiment of a manufacturing method. In the second embodiment, the manufacturing method comprises the steps of: (a) forming a certain pattern of filaments151′ by tying filaments151′ with a strap14′; (b) inserting the certain pattern of filaments151′ to the slot11-3; (c) forming a brush15by injecting an adhesive into the slot11-3into which the certain pattern of filaments151′ is inserted or vibration-fusing or thermal-fusing the slot; and (d) cutting and removing the tied strap portion from the brush rod11formed with the brush15. As illustrated inFIG.9A, first, the certain pattern of filaments151′ are formed by tying knots on the strap14′ to have the certain pattern of filaments151′. The knots formed on the strap may be formed by knitting the filaments, binding the filaments or attaching the filaments to the strap14′. Next,FIG.9Billustrates a step (b) of inserting the filaments151′ tied with the certain pattern of knots on the brush rod11into the slot11-3. The brush rod used in step (b) may use the brush rod ofFIGS.1to5. As illustrated inFIGS.2and4, even when the slots11-3a,11-3b,11-3a′, and11-3b′ are formed in a multilayer, since the filaments151′ are inserted into the slot, the same step is applied. InFIG.9C, when the filaments151′ are inserted into the slot11-3, step (c) of fixing the filaments151to the brush rod11is performed. To this end, the filaments151′ are fixed by applying the adhesive on the slot11-3or fusing the slot11-3by the vibration fusion machine20or thermal fusion machine20. The vibration fusion includes ultrasonic fusion or high-frequency fusion. The filaments151′ inserted into the slot11-3are fixed to form the brush15. Next,FIG.9Dillustrates step (d) of cutting the strap14′ portion fixing the filaments151′ when the filaments151′ are inserted into the brush rod11. Next,FIG.9Eillustrates step (e) of further including a step of cutting the end of the brush in a certain form to form a certain shape of cutting line15-1on the end of the brush15when the brush15is fixed and adhered to the brush rod11. The cutting line15-1may be variously formed in the form illustrated inFIG.11. Further, a curling may be formed without cutting the end. Further, the mascara brush may be manufactured by using the curled filaments according to the process.
