Abstract
An apparatus (1) is used in the production of brushes for the preparation of completely processed bristle bundles. Bristle strand material (4) is thereby conveyed with the aid of a feed mechanism (5) to a grinding device (6) where its free ends are processed into what will become the ultimate useful ends. By this processing, the free length of the bristle strand ends, and thus their ability to deflect laterally during grinding as well, can be exactly adjusted to this work procedure. This processing can be adapted to differing bristle material, or even adapted to differences in the desired rounding off results. The actual length of the final bristle bundles does not play a role in this, since the cutting of the bristle bundles to length does not take place until a following work step.
