  • Patent number: 11547202
    Abstract: A mascara brush having a centre made of at least two wire sections twisted together along a longitudinal axis of the wire core, and having a bristle covering made of plastic bristles formed by filaments, each of which bristles is held in a clamping manner between the two wire sections, and which bristles are formed with a wedge-shaped bristle tip or without a wedge-shaped bristle tip on their free ends. At least one portion of the bristles has a bristle coating made of a first softer material, and a bristle core that is joined to the bristle coating and made of a second harder material, and at least these bristles have a transverse cut, in the form of a simple wedge, on one side or on two sides, at least partially on their radially outward free ends, and comprise a wedge-shaped bristle tip having at least one cut surface forming a wedge.

  • Publication number: 20210022481
    Abstract: The invention relates to an eyebrow applicator (1) comprising bristle-forming filaments (5) retained in a clamped manner between at least two wires (3, 4) twisted together, characterised in that at least one portion of the bristle-forming filaments (5) has a cross-section (perpendicular to the longitudinal axis thereof) formed by a solid core (7) from which at least 8, preferably at least 10 ribs (8) and ideally 12 ribs (8) protrude radially on all sides, wherein the outer diameter of these filaments (5) is at least 0.25 mm, the length of the bristles (6) formed by these filaments (5) is max, 3 mm, and the material of these filaments (5) has a hardness of <60 Shore D.

  • Patent number: 10499725
    Abstract: A mascara brush with a core comprising at least two sections of wire twisted together along a wire core longitudinal axis and a set of bristles comprising bristles of plastic formed by filaments, which are respectively clamped between the two sections of wire and are formed at their free ends with a wedge-shaped bristle tip or without a wedge-shaped bristle tip. The mascara brush provides an increased storage capacity for the mascara composition to be applied with improved delivery of stored mascara composition to the lashes. This is achieved by the bristles being formed from a plastic material extruded into a fibre, to which outwardly protruding particles are added and/or which is provided with punctiform depressions (indentations), which roughen the bristle surface, wherein the bristles that have a wedge-shaped bristle tip at their free ends comprise at least one cut surface that forms a wedge and the surface roughness of which lies between 0.2 ?m and 6.3 ?m, in particular between 2.9 ?m and 6.3 ?m.

  • Patent number: 9901159
    Abstract: A wire core brush, preferably in the form of a cosmetic or mascara applicator, having bristle-forming elements held between at least two wires that are twisted together, forming bristles arranged essentially along at least one helix, between which a helical open space is provided, characterized in that the helical open space is partially filled by a film strip, which wraps around circumference surface shared by the wires that are twisted together.

  • Publication number: 20170215565
    Abstract: A mascara brush comprising a core made of at least two wire sections twisted with one another along a wire-core longitudinal axis and a set of bristles made of bristles formed from plastic filaments, each of said bristles being held in a clamped manner between the two wire sections and being formed on the free ends thereof with or without a wedge-shaped bristle tip, wherein the bristles, at least partially, are formed from internally hollow filaments, a solution is provided with which the mass delivery in relation to the known applicators is improved. Same is achieved in that, in particular at least, the bristles formed on the inside in a hollow manner on the radially outward free ends have an oblique cut in the form of a simple wedge and comprise a wedge-shaped bristle tip comprising at least one cut surface forming a wedge.

  • Patent number: 4055120
    Abstract: In a rotary printing machine, the cylinder for holding the printing plate has a printing plate tensioning device formed in it, which includes an adjustably positionable tensioning rail. To adjust this rail, a set of marks is formed on the cylinder. A support base carries an optical device to view the marks. On the base there are tensioning rail engaging adjustably positionable abutments and the alignment of the marks in the field of view of the optical device enables proper positioning of the abutments and of the tensioning rail.
