Abstract (en)
[origin: DE4006325A1] The brush bristle active ends processing starts with forming bristle tights and clamping them at a distance from the active ends. After cutting to size, the active ends are ground. The grinding is carried out by a surface, orthogonal to the bristle extension, whose all points move on circular tracks of identical dia. The bristle compression against the grinding surface is variable, and the bristles are supported at a variable spacing.
