    • [Problem]Disclosed is a method for manufacturing a spherical brush having highly dense brush bristles for easy cleaning of periodontal pockets and a cylindrical brush having the brush bristles highly dense brush bristles at a ball portion of a tip thereof, and a brush manufactured by the manufacturing method.[Solution means]A fiber bundle, which is composed of a number of short fibers prepared by cutting long fibers, is gripped between a set of U-shaped wires arranged to crisscross with each other to form a loop. The open ends of the U-shaped wires are pulled and twisted in opposite directions, so that the fibers at the portion gripped by the U-shaped wires are compressed to reduce the size of their bundled areas. Elastic repulsion is established between the fiber bundles near a wire-gripped portion by the size differences of the cross sectional areas of the free end fibers at both ends of the wire-gripped portion, and is utilized so that the free end fibers diverge radially to the circumference from the wire-gripped portion.
    • 本发明公开了一种球状刷的制造方法,该球形刷具有高密度的刷毛,用于容易地清洁牙周袋,以及具有刷毛刷毛顶端的高度致密的刷刷毛的圆筒刷, 制造方法。 [解决方案]通过切割长纤维制备的由许多短纤维组成的纤维束被夹持在彼此交错排列的一组U形丝之间以形成环。 U形电线的开口端被拉向并在相反的方向上扭转,使得被U形电线夹住的部分处的纤维被压缩以减小其捆扎区域的尺寸。 通过线夹持部分两端的自由端纤维的横截面面积的尺寸差异,在线夹持部分附近的纤维束之间建立弹性斥力,并且使用自由端纤维径向分散到 来自线夹的部分的圆周。
