DEVICE FOR FILAMENT END-ROUNDING AND A METHOD FOR END-ROUNDING (TOOTH)BRUSH FILAMENTS

摘要

An end-rounding device comprises a movable body comprising an abrasive surface; a gearing for transferring a movement from a motor to the movable body; a providing unit for providing a plurality of bristle filament ends to the abrasive surface, wherein the providing unit comprises a clamping unit for clamping a bunch of filaments, wherein the bunch comprises a multiple of filaments of a bristle tuft; wherein the abrasive surface has a diameter from 80 mm to 300 mm and comprises a concave curvature oriented in the direction of the clamping unit; and wherein the clamping unit is movably spaced from the abrasive surface at a distance. A method of smoothening bristle filament ends utilizes the end-rounding device.
