Abstract

PURPOSE:To obtain a brush having a high accuracy and good quality by forming a longitudinal bead at the center of each strip material when a plurality of slits are punched at one end of a plate material to produce brushes of the strip material, thereby eliminating the twist and the inclination of the material. CONSTITUTION:When a plurality of slits 5 are punched from one end of a plate material 4 to produce sliding brushes 7'' made of a plurality of brush strip materials 6, a longitudinal bead 6a is formed at the center of each material 6. The bead 6a may be formed by compression with a punch of strip shape. In this manner, the irregularity in the width of each slit 5 and the step of each material 6 can be remarkably reduced, thereby obtaining a brush having good quality.
