Abstract

1. Method of treating the free ends of natural bristles used for the making of tooth brushes, characterised in that it consists of applying the free ends of bristles to a wheel (10) according to a combined relative movement composed of a to-and-fro oscillation (14, 14') of the bristles above the wheel (10) in a plane perpendicular to the grinding plane, the said wheel (10) being rotated (N) about its axis (12), disposed parallel to the grinding plane, and in that the combined relative movement further comprises a simultaneous rotation (n) between the wheel (10) and the bristles, about an axis (13) substantially perpendicular to the grinding plane.
