An apparatus (1) for forming bristle bundles (2), the apparatus (1) comprising:

• at least one bundle pocket (3) for receiving at least one bristle bundle (2),
• a heating apparatus (4) for heating the at least one bundle pocket (3),
• the bundle pocket (3) has at least one introduction opening (5) and at least one lateral cutout (6) therein,
• a displacement pin (7) configured for profiling the at least one bristle bundle (2) that has been introduced into the bundle pocket (3) is configured to be inserted through the at least one lateral cutout into the bundle pocket (3) transversely or orthogonally to an introduction direction of the at least one bristle bundle (2), such that the at least one bristle bundle (2) that has been introduced into the bundle pocket (3) is adapted to be formed from a non-deformed initial shape to a desired target shape under an effect of heat from the heating apparatus (4) that is adapted to be dissipated to the bundle pocket (3).
