摘要:
A brush and in particular a tooth brush comprises a brush body and a bristle carrier supporting a plurality of bristles and being preferably removably retained on the brush body. The bristle carrier, consisting of soft-elastic plastic material, is formed as a cap and can be drawn over a projection of the brush body.

Methods for the use of laser beams in the case of plastic monofilaments are proposed. For the optical marking of extruded monofilaments or individual monofilaments of a monofilament union, at least the monofilament to be marked, accompanied by the addition of additives reacting with a color change under laser action, are extruded and treated with laser beams in the areas corresponding to the desired marking.
摘要:
A monofilament with antimicrobial properties for use as bristle consists of an extruded polymer with silver particles which are dispersed in the polymer matrix, and is characterized in that the silver particles have a particle size which is predominantly between 100 nm and 10 μm and are disposed along the cross-section of the monofilament with the particle size decreasing from the outside to the inside. The use of such monofilaments and brushes or paintbrushes having bristles of such monofilaments is also described.
摘要:
In a method for producing a monofilament with reduced secondary binding forces of at least two commonly extruded polymers for the production of bristles or interdental cleaners which are slittable substantially axially through the action of mechanical forces, the at least two polymers of the monofilament are disposed in a regular geometrical arrangement with substantially axially extending boundary layers in which the reduced secondary binding forces prevail for generation of defined slits of flags.
摘要:
A gingival massaging and tooth cleaning brush comprises a bristle carrier with handle and on the bristle carrier individual or bundlewise fixed plastic bristles. For improving the massaging action the bristles are waved transversely to their axis, accompanied by the formation of distinct, stud-like wave tops and with a short wave length.
摘要:
A paint application roll, particularly for a paint roller having a bow-shaped support member provided with a handle and on which the roll can be mounted in rotary manner, has a circular cylindrical carrying body onto whose circumferential surface is applied at least one structural element, which gives the roll surface a height-profiling functionality. Preferably the structural element is held in a replaceable manner on the carrying body and can be a tubular sleeve part externally axially mountable on the carrying body.
摘要:
For the treatment of bristles of brushes, the bristles are fixed in spaced manner from the use-side ends, which are cut to size and subsequently treated by a planar abrading surface arranged at right angles to the bristle extension and all of whose points are moved on circular paths having the same diameter. For setting the contact pressure the abrading surface is fed in the direction of the bristles and for influencing the treatment result the bristles are laterally supported between their fixing point and their use-side ends in a variable spacing from the abrading surface, but which is always the same for all the bristles.
摘要:
A process and apparatus for the production of bristle articles include introducing the plastic bristles in the form of individual bristles or bristle strands through channels and sleeves extending the latter in to a mould for the bristle carrier, followed by thermal melting on their end located on the mould for formation of a thickened portion and the thickened portion on the bristle ends formed during melting is then sealingly engaged on the opening of the sleeve projecting into the mould. During the filling of the mould, the bristles and sleeve are kept in position within the same and the sleeve and the thickened portion on the bristle end tightly engaging against the opening of the sleeve are enveloped by the bristle carrier material during mould filling and then the sleeve is removed from the bristle carrier.
