Abstract: A brush stuffing machine comprising a bristle magazine and a stuffing tool which is movable between a bundle take-over position and a stuffing position, the stuffing tool is pivotally mounted about an axis for movement on a circular arc between the take-over position and the stuffing position.

Abstract: A toothbrush comprises a brush body with a brush head and a carrier platelet attached to the brush head. A plurality of bristle bundles consisting of a thermoplastic material are attached anchor-less to the platelet. The brush head in addition has: bores, recesses or holes which have bristle bundles inserted and affixed with anchors or loops; and/or bores, recesses or holes which have knobs, pegs, pointed bristles or pointed cones inserted therein; and/or knobs, pegs, pointed bristles or pointed cones attached to the brush head.

Abstract: Method for manufacturing plungers for medical syringes, whereby such a plunger (3) consists of at least two parts, namely a longitudinal plunger body (4) made of plastic and a piston body (5) provided at the front end of the plunger body (4) which consists of a plastic which is softer than the plastic of the plunger body (4), characterised in that such a plunger (3), or at least a part (36) thereof, is formed by first manufacturing the piston body (5) and then the plunger body (4), or at least a part (37) of this plunger body (4), by means of injection moulding, whereby the plunger body (4), or the above-mentioned part (37) thereof, is injected against the piston body (5).

Abstract: A tuft picker device for a brush making machine has a bristle magazine for holding a supply of loose bristles, a tuft picker having a tuft picking notch being movable past an open side of the bristle magazine in a working stroke. A shield member is adapted to be shifted across the tuft picker notch to change the effective depth thereof. The shield member can be adjusted by an adjusting device in each working stroke in order to vary the effective depth of the tuft picking notch from one working stroke to the next to change the size of a tuft engaged in the notch.

Abstract: Device for compensating the vibrations caused by the movements of a tool of a brush manufacturing machine, more particularly of a tool (1) having at least one slide (2) which is provided in a first guide (3) such that is can move to and fro and which is provided with driving device (4) for this slide, wherein the device includes a compensating mass (16) and of a moving device (17) to move this compensating mass (16) in the opposite sense of the movement of the slide (2).

Abstract: Device for manufacturing brushes by means of successive operations, which mainly consists of a number of brush holders (9-11) which are provided on a means of transport and which can be moved between different posts (5-8) which are provided along the means of transport, more particularly working posts (6-8) where a processing can take place and/or waiting posts (5) where the brush holders (9-11) can be put in a wait position, characterized in that the means of transport is provided with means which make it possible to move the brush holders (9-11) independently from one another.

Abstract: Device for manufacturing brushes, more particularly for inserting fibers in a brush body, which device mainly consists of a filling tool and at least one supply duct, characterized in that between the supply duct (3) and the filling tool (7) is provided at least one rounding means (16).

Abstract: A brush tufting machine includes a machine tool table having a slide that is displaceably guided on the machine tool table in at least two mutually orthogonal directions. A first drive is provided for reciprocating the slide in a first one of the two directions, and a second drive is provided for reciprocating the slide in a second one of the two directions. Two drums are mounted at the slide for rotation about parallel, spaced axes. Two tufting tools are arranged at the machine tool table at a distance from each other and each in opposition to a peripheral surface of one of the drums. The peripheral surface of each drum has brush body holders arranged thereon.

Abstract: Method for manufacturing brushes whereby openings (3) for bundles of fibers (5) are provided in a brush body (2), to which end the brush body (2), while it is placed in a positionable brush body holder (18), is being presented to a boring tool (19), whereby this boring tool (19) is moved to and fro according to the boring direction in order to carry out the actual boring operation on the one hand, and in order to provide for a depth compensation on the other hand, characterized in that the actual boring operation and the depth compensation are realized by means of a single drive element (24).

Abstract: Method for manufacturing brushes, whereby bundles of fibers (2) are provided in openings (3) in a brush body (4) by means of a filling tool (5) of the type which at least consists of a bundle remover (7) for separating bundles of fibers (2) from a fiber magazine (8), a mechanism (9) for supplying fastening material (10) in order to fix the bundles of fibers (2) in the openings (3), a filling tool slide (11) moving to and fro to guide the bundles of fibers (2) to the brush body (4) and a needle (13) to put every bundle of fibers (2) concerned in the corresponding opening (3) together with a fastening element (14) formed of the fastening material (10), characterized in that at least the filling tool slide (11) is controlled by means of an individual electric drive element (27).
