A brushroll dowel for a vacuum cleaner having bristle stiffeners protruding from a brush dowel. The brushroll can be made using an injection molding process, with the bristle stiffeners integrally molded with the brush dowel and a plurality of stiffened bristles protruding from the brush dowel adjacent to the bristle stiffeners.

An apparatus (1) for forming bristle bundles (2) is provided. The apparatus (1) includes at least one bundle pocket (3), intended to receive a bristle bundle (2) to be formed. The bundle pocket (3) has at least one piercing (6) in the side. A displacement device (7) on the apparatus (1) can be introduced into the bundle pocket (3) through this piercing (6) to create a clearance (29) inside a bristle bundle (2) to be formed. The bundle pocket (3) and the bristle bundle (2) located therein are heated by the heating device (4) in the apparatus (1) to fix the shape of the bristle bundle (2) defined by the bundle pocket (3) and the displacement device (7).

A feeding device for feeding batches of bristle filaments to a bristle filament cassette includes a vertical magazine and at least one batch of bristle filaments arranged therein. In order to prevent individual bristle filaments from being pressed out of the batch of bristle filaments and to provide an ecologically optimized device, the batch of bristle filaments is held in a reusable and circumferentially enclosed batch carrier. A tufting device with the feeding device of a bristle filament cassette and a transfer device between the bristle filament cassette and the feeding device are provided. A corresponding method for fitting a brush is also provided.

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.

A brush for cosmetic implements includes a brush part attached to a support member; the brush part includes a plurality of synthetic resin fibers whose tip end has a conically tapered surface, and a plurality of fiber bundles composed of a plurality of synthetic resin fibers is formed at least three places in a radial circumferential surface of the support member, and further formed in an axial direction of the support member. Provided is a brush for a cosmetic implements in which a brush bristle having a tapered end is provided around the support member in the radial direction, and a manufacturing method thereof.

A method of tufting, with a tufting tool, a brushroll dowel for a vacuum cleaner having a bristle stiffener protruding from the dowel and a bristle hole adjacent the bristle stiffener. The tufting tool includes a notch. The method provides a brushroll with bristles tufted into the bristle hole adjacent the bristle stiffener. A brushroll for a vacuum cleaner can be made using an injection molding process, with bristle stiffeners integrally molded with the dowel and a plurality of stiffened bristles protruding from the brush dowel adjacent to the bristle stiffeners.
