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.

Transfer station for transferring bristle filaments

An apparatus () for producing bristle arrangements for brushes, in particular toothbrushes, having a bristle supply () and an apparatus () for extracting individual bundles () of bristles from the bristle supply (), and also having a transporting apparatus for transporting the bundles () of bristles by way of at least one hollow line () by means of a stream of gas or air in perforations in a bundle-retaining plate, is characterized in that the apparatus () for extracting the bundles () of bristles from the bristle supply () has at least one bundle holder (), and in that the bundle holder(s) () of the extraction means (), the inner contour () of the hollow line(s) () and the perforations in the bundle-retaining plate are each contoured in a manner corresponding to the bundle contour which is desired in the bristle arrangement.

Apparatus for producing bristle arrangements for brushes

In a method for producing bristle areas for brushes, in particular toothbrushes, bundles of bristles () are divided off from a bristle supply (), transported by a gas or air stream (Pf) and introduced into perforations () in a central plate (). The bundles of bristles () are removed from the central plate () and transferred to a compactor plate () and, in the process, the density of the bundle of bristles () is increased. In the apparatus for producing bristle areas for brushes, in particular toothbrushes, having a bristle supply () and an apparatus () for removing individual bundles of bristles () from the bristle supply (), and a transport apparatus () for transporting the bundles of bristles () into perforations () in a central plate () by a gas or air stream (Pf), a compactor plate () that has perforations () for receiving bundles of bristles () is arranged downstream of the central plate (), with the cross-sections of the perforations being smaller than the cross-section of the bundle of bristles () supplied to the respective perforation (). An apparatus is provided for forwarding the bundles of bristles () from the central plate () to the compactor plate ().
