Method and apparatus for producing bristle areas for brushes

摘要

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 plate (21) to the compactor plate (106).

1. A method for the production of bristle areas for brushes, comprising separating partial bundles of bristles (5a, 5b) from a bristle supply (101), transporting the partial bundle of bristles via a gas or air flow (Pf1) and inserting the partial bundles of bristles into perforations (22) of a central plate (21), wherein at least two of the partial bundles of bristles (5a, 5b) positioned offset in an axial direction to one another in the bristle supply direction are pushed together and inserted into the same perforation (22) of the central plate (21) and pressing the bristle bundles (5) in the central plate (21) into a compactor plate (106), using a plurality of hole pins (43b) inserted into and movable through the perforations (22) in the central plate (21) wherein the at least two of the partial bundles of bristles that were previously pushed together and inserted into the same perforation of the central plate are pressed into the compactor plate (106) using a single one of the hole pins (43b), and wherein the compactor plate (106), that includes a plurality of perforations (108) to receive the bristle bundles (5) from the central plate (21), with cross-sections of the perforations (108) that contact sides of the bristle bundles each being smaller than a cross-section of the bundle of bristles (5) supplied to the respective central plate perforation (22) so that a bristle density of the bristle bundles (5) is increased during insertion.
