A brush includes a brush head which comprises a brush support, and a plurality of brushing members integrally provided on the brush support, wherein the brushing members and the brush support are integrally formed together by heat treatment.

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.

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). Further a brush production machine (20) having a wire-forming device (19), by which, in at least one region (4a, 6a, 13a) of a wire portion (3) to be profiled, a cross section of the wire portion (3) can be modified such that the wire portion (3) after profiling has at least two regions (4a, 6a, 13a) with differently formed cross sections.

According to a method or an apparatus for fastening bristles in a bristle carrier (10) without using an anchor a heating (39) is provided in a tool part configured to transport the bristles. After inserting the bristles into anchoring openings (12) in the bristle carrier (10), the anchoring openings are closed by applying pressure.

An environmental-friendly paintbrush without bristle-implanting holes includes a handle, a bristle-implanting brush head, and a metal plate. The bristle-implanting brush head may have one end provided with a bristle material-laying trough, and another end connected with the handle. A plastic block may be placed inside the bristle material-laying trough. Bristle material may be filled in an interstitial space between the plastic block and the bristle-implanting brush head. The plastic block is formed with a metal-laying trough. The metal plate is set inside the metal-laying trough. Two ends of the bristle material-laying trough are formed with metal slots provided inside the brush-implanting brush head. Two ends of the metal plate are slotted into the metal slots. A method of processing an environmental-friendly paintbrush without bristle-implanting holes is also disclosed.

The present invention provides an apparatus for combining a brush. The apparatus for combining a brush includes: a brush-fitting unit that is coupled to a main body and couples a fixing member for fixing a brush hair part of a brush to a brush body by pressing the fixing member; a brush-feeding unit that is coupled to the main body to feed the brush to the fitting unit; and a brush-rotating unit that is combined with the brush-feeding unit, and rotates the brush.

The present invention provides a brush and a manufacturing method thereof. A brush of the present invention includes: brush hairs; a brush hair part that has a brush coupler to which the brush hairs are attached; a brush body that support an end of the brush coupler; a coupling member that has a first part coupled to the brush body and a second part coupled to the edge of the brush coupler and has a metallic tube; and a fixing member that prevents shaking of the brush coupler between the brush body and the brush coupler, in which the coupling member and the brush body are combined by pressing the portion of the coupling member where the coupling member and the brush body are in contact with each other.

Improvements in the technical field of brush manufacturing include providing a profiling device (25) for profiling a set of bristles (3) of a brush (1) to be manufactured, which profiling device is set up to profile a cleaning side (27) of the set of bristles by axially displacing bristle filaments (4) of the set of bristles (3) relative to their longitudinal axes.
