ABSTRACT:
For the treatment of bristles of brushes, the bristles are fixed in spaced manner from the use-side ends, which are cut to size and subsequently treated by a planar abrading surface arranged at right angles to the bristle extension and all of whose points are moved on circular paths having the same diameter. For setting the contact pressure the abrading surface is fed in the direction of the bristles and for influencing the treatment result the bristles are laterally supported between their fixing point and their use-side ends in a variable spacing from the abrading surface, but which is always the same for all the bristles.
