Abstract

A manufacturing method for producing a cosmetic applicator brush is disclosed. The method comprises a first step of cutting and bending a plurality of wires, a second step of stacking a plurality of discs along the plurality of wires, a third step of twisting the plurality of wires to form a desired angle, and a fourth step of coining and cutting the plurality of wires to produce the cosmetic applicator brush. The movement among the first step, the second step, the third step, and the fourth step is done via a conveyer belt system. All of the first step, the second step, the third step, and the fourth step are performed by a single machine or system.
