A nozzle structure with a plurality of bristle bunches includes a mouth-shaped casing and a plurality of bristle bunches. The mouth-shaped casing has a first end portion with an air inlet and a second end portion opposite to the first end portion. The second end portion has a plurality of outlet pores arranged in parallel and a plurality of bristle pores. Each of the outlet pores connects to the air inlet via a ventilated space inside the mouth-shaped casing, and the plurality of bristle bunches are implanted in the bristle pores of the mouth-shaped casing. In addition, the bristle bunches protrude further out from the outlet pores.

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.

The invention relates to a method for manufacturing a brush seal with inclined bristles. In order to be able to manufacture these brush seals in an especially cost-effective manner, at least the following steps are provided: provision of a brush blank with at least one metal thread or wire packing fastened at or in at least one wire core; local, at least partial heating of at least the wire core and/or a subregion of the thread or wire packing adjacent to the wire core, by a current flow through the wire core; bending of the thread or wire packing relative to the wire core for producing of the inclined position of the bristles of the brush seal. The invention further relates to an apparatus for manufacturing brush seals and a brush seal for a turbomachine, in particular for an aircraft engine.

An applicator for a cosmetic product, in particular mascara, comprises a twisted core and fibers which extend from the core and are held by the core, the core having a main longitudinal direction of extension, known as the main axis (X), and the core being rectilinear along the main axis (X), the fibers forming an envelope (E) with their free ends, characterized in that the envelope (E) comprises, along the main axis (X), a substantially concave face (F1) and a substantially convex, opposite, face (F3).

An applicator for a cosmetic product, in particular mascara, comprises a twisted core and fibres which extend from the core and are retained by the core, the core extending in a main longitudinal direction, referred to as the main axis (X), the core being rectilinear along the main axis (X), and the fibres forming an envelope (E) with their free ends. The envelope (E) has four faces (F1-F4), the faces (F1-F4) each having a plane of symmetry comprising the main axis (X), each of the four faces (F1-F4) being generated by a straight line, referred to as a generating line, orthogonal to the main axis (X) and orthogonal to the plane of symmetry of the face (F1-F4), at least two consecutive faces (F1, F2) of the four faces (F1-F4) having a curved profile along the main axis (X).
