Abstract: A shearing device (1) having a blade (2) with at least one blade cutting edge (5) which is helically coiled, and rotatable, about an axis of rotation (R) of the blade (2). The blade cutting edge (5) is assigned a counterpart blade cutting edge (4) of a counterpart blade (3). The shearing movements, by which for example bristle filaments (7) of brushes (8) for machining can be cut to length, are generated by relative rotational movement of the at least one helically coiled blade cutting edge (5) with respect to the preferably static counterpart blade cutting edge (4) of the counterpart blade (3). Since the blade (2) and the counterpart blade (3) can keep their spacing to one another constant during operation, there is a relatively low risk of injury during the use thereof.

Abstract: A twisted brush (1) having a bristle carrier (2) made of twisted together wire portions (3) which have oval and/or elliptical cross sections, at least in the distal portion (4) of the bristle carrier (2). Further, a twisted brush (1) whose bristle carrier (2) has an extraction protection (12) at a distance from its proximal end (11) is also provided. Using this extraction protection (12), the bristle carrier (2) can be fastened to the handle (7) of the twisted brush (1) in a manner protected against extraction. Moreover, a method for producing a twisted brush is also provided, wire portions (3), of which at least one is profiled, i.e. has at least two regions (4a, 6a, 13a) with different cross sections, are twisted together to form the bristle carrier (2).

Abstract: An apparatus for producing round brushes, which have bristles twisted in between two portions of a folded wire. The apparatus has a bristle feeding device and a rotary gripper for twisting two portions of wire with bristles located therebetween, a deflecting device with two deflecting rollers spaced apart in the longitudinal direction of the wire. The rotary gripper is linearly displaceable transversely in relation to the longitudinal direction of the wire, for gripping the folded region of the wire that is formed by force being applied by an application element that is adjustable between the deflecting rollers transversely in relation to the longitudinal direction of the wire. A bristle feeding device, for feeding bristles to the bent-around portions of wire, is provided in the region of the deflecting rollers. In the region of the unfolded portions of wire there is provided a device for slowing the advancement of the wire.

Abstract: The invention is a pre-scented and custom treated card for use with a vacuum cleaner having an intake nozzle, a receptacle and a blower that creates a flow from the nozzle to the receptacle so as to carry dirt from the nozzle into the receptacle. The pre-scented and custom scented card includes a card and oil containing a fragrance, an anti-bacterial agent and/or an odor eliminator. The card is formed from a material that is capable of absorbing a fragrance. The oil containing the fragrance, the anti-bacterial eliminator and/or the odor eliminator are disposed on the card. The card may be cut into a plurality of strips that are then inserted into the receptacle through the opening of the bag or receptacle.
