This clamping element (14) can be advanced transversely with respect to a longitudinal axis of the plug-in receptacle (13) from a starting position into a clamping position in which it secures the bristle carrier (7) via its fastening stud (12) on the clamping apparatus (8).

Abstract: A method for the manufacture of scrubbing brushes and/or painting brushes is provided, in which a processing pressure exerted by a processing tool (3, 4) onto a bristle holder (5) to be processed is determined by a pressure sensor (6), which has a pressure-recording surface (7), which is arranged behind the bristle holder (5) to be processed, in the operating direction of the processing tool (3, 4). In this manner, determination of the processing pressure is possible close to the bristle holder (5) to be processed.

Abstract: A transfer station for bristle filaments that are fed to the transfer station in bristle bundles is provided. The bristle filaments are assembled in bundle form by at least one band and are transferred to a magazine in which the bristle filaments are stored. The transfer station has at least two pairs of gripping fingers spaced apart from one another in the longitudinal direction of the bundles, with the gripping fingers of the gripping-finger pairs being movable relative to one another in order to grip a bristle bundle by a distance between said gripping fingers being reduced. The gripping-finger pairs grip the bristle bundle such that the band of the bristle bundle is arranged between adjacent gripping-finger pairs. This makes it possible for the bristle filaments fed in bundle form to be transferred in an automated manner to the magazine arranged upstream of a stuffing tool of a brush-production machine.

Abstract: In the technical field of the production of brush production machines (1), a construction kit for the production of brush production machines (1) is inter alia provided. This modular construction kit includes at least one basic module type (2a) and a deflection module type (3a), the modules (2, 3) thereof having standardized connection interfaces 5 by which the modules (3) are inter-coupleable to form a brush production machine (1). Since each of the modules (2, 3, 4) is coupleable to each module of the different module types (2a, 3a, 4a), a large number of different brush production machines (1) can be configured by way of this construction kit, without a particular constructive effort being required to this end.

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.

Abstract: A tufting tool for tufting and fastening clusters of bristles in bristle holes in a contoured surface of or oblique holes in a brush body. The tufting tool has a tool head displaceable along the tufting axis between a receiving and a tufting position. The tool head has two guide jaws which are displaceable relative to each other during displacement of the tool head.
