Abstract:
1. A method for the production of bristle areas for brushes, comprising separating partial bundles of bristles ( 5 a , 5 b ) from a bristle supply ( 101 ), transporting the partial bundle of bristles via a gas or air flow (Pf 1 ) 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 ( 5 a , 5 b ) 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 ( 43 b ) 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 ( 43 b ), 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.
