Abstract
A method and device for manufacturing bristle arrangements for brushes. The brush is populated with a carrier pad, and to enable simplification of the manufacture of bristle arrangements for brushes, the bristle bundles which are conveyed by a gas or air stream through the conveying device to the bundle-retaining plate, when being conveyed through the conveying device are electrostatically discharged, such that they are more easily conveyed through the conveying device, and in that they reduce the complexity in the fastening of bristle bundles in a carrier pad without anchoring, since the carrier pad on the rear side has material protrusions which are fused and thereafter interference-fitted in a bundle-fastening plane, in order for bristle bundles which have been incorporated into the perforations of the carrier pad to be connected in a form-fitting and/or force-fitting manner to the carrier pad in a simple manner.
