Abstract: A transfer station for bristle filaments that are fed to the transfer station in bristle bundles is provided. The bristle filaments are assembled in bundle form by at least one band and are transferred to a magazine in which the bristle filaments are stored. The transfer station has at least two pairs of gripping fingers spaced apart from one another in the longitudinal direction of the bundles, with the gripping fingers of the gripping-finger pairs being movable relative to one another in order to grip a bristle bundle by a distance between said gripping fingers being reduced. The gripping-finger pairs grip the bristle bundle such that the band of the bristle bundle is arranged between adjacent gripping-finger pairs. This makes it possible for the bristle filaments fed in bundle form to be transferred in an automated manner to the magazine arranged upstream of a stuffing tool of a brush-production machine.
