摘要:
An end-rounding device and a method for smoothening and end-rounding bristle filament ends, for the use in brush heads, in particular toothbrush heads, is provided. Thereby, bristle filament ends can be provided which end-rounding quality shows a high homogeneity although more than one end is end-rounded in one step. Thus, the method and the device can be used for end-rounding of bigger bristle arrangements, such as bristle bunches comprising a multiple of filaments used for one bristle tuft.

The present invention relates to a method of tapering a toothbrush bristle which increases production efficiency. The method includes the steps of cutting bundles of toothbrush bristles; and non-directionally immersing the entire cut bundles of toothbrush bristles into a chemical solution to taper both sides of the toothbrush bristles. According to the present invention, the production efficiency of a needle-shaped bristle is increased approximately three times, and the loss of raw materials is greatly decreased because several processes are not performed.

The present invention provides a needle-shaped bristle and a method of manufacturing the needle-shaped bristle. The manufacturing method of the present invention includes the steps of cutting and removing a packing sheet, which is wound around a bundle of bristles, by a length ranging from 30 mm to 50 mm from a first end thereof, and grinding first ends of the bristles using a rotating grinder. The manufacturing method further includes steps of packing the first end of the bundle of bristles, from which the packing sheet is removed, using a packing sheet, cutting the bundle of bristles to a length ranging from 22 mm to 32 mm, and immersing a second end of the cut bundle of bristles, thus tapering second ends of the bristles. The needle-shaped bristle has an advantage of realizing a reduction in the proportion of defective products.

According to the invention, during the production of bristles (12), at least some bristles in a bristle trim are split by mechanical forces in at least one subsection of their length into several partial cross-sections or fingers which are separate from each other. In order to produce bristles with defined fingers in a simple manner, independently of the mutual arrangement of said bristles, the mechanical forces are exerted from different directions (R1 to R8) in relation to the longitudinal axis of the bristles (12). In particular, a blunt tool (13) without a cutting edge is used, for example, a striking tool.
