Abstract
In a method for producing bristle areas for brushes, in particular toothbrushes, bundles of bristles (5) are divided off from a bristle supply (101), transported by a gas or air stream (Pf 1) and introduced into perforations (22) in a central plate (21). The bundles of bristles (5) are removed from the central plate (21) and transferred to a compactor plate (106) and, in the process, the density of the bundle of bristles (5) is increased. In the apparatus for producing bristle areas for brushes, in particular toothbrushes, having a bristle supply (101) and an apparatus (102) for removing individual bundles of bristles (5) from the bristle supply (101), and a transport apparatus (103) for transporting the bundles of bristles (5) into perforations (22) in a central plate (21) by a gas or air stream (Pf 1), a compactor plate (106) that has perforations (108) for receiving bundles of bristles (5) is arranged downstream of the central plate (21), with the cross-sections of the perforations being smaller than the cross-section of the bundle of bristles (5) supplied to the respective perforation (108). An apparatus is provided for forwarding the bundles of bristles (5) from the central pl…
