A process and apparatus are provided for executing profiling trimming cuts in the bristle fields of toothbrushes. In order to process the fibers separately in different regions of the bristle field, and particularly to shorten them by means of a straight cutter or a level grinding disk, the fibers in the bristle field regions that are not to be contacted by the processing tool, are held at a distance from the processing plane of a processing tool by means of a lateral deflection of the free fiber ends in the longitudinal direction of the respective bristle field region. If the process is employed in several steps, in which respective fibers from various bristle field regions are to be processed, almost any desired profile cross-section can be created in the bristle field, not only in the longitudinal direction but in the transverse direction as well. Processing at each processing stage can thereby be accomplished with straight processing tools, for example with straight cutters. It is thus possible to dispense with the use of expensive profile cutters.
Apparatus for executing profiling trimming cuts in a bristle field of a brush, said bristle field comprising fibers which extend in a first direction from a body of the brush and an area of the field having a longitudinal axis substantially perpendicular to the fibers, wherein fibers in a first portion of the bristle field area make contact with a processing level of a processing tool, while fibers in a second portion of the bristle field area are not in contact with said processing level, said apparatus comprising a pushing element which impinges upon the fibers at their free ends for deflection of the fibers of the second portion of the field, and means for moving the pushing element and the brush relative to one another in the longitudinal direction of the bristle field area.
