摘要： Brush ware comprising at least one carrier and bristles made from a moldable plastic material disposed thereon, is produced by providing the carrier with through holes acting like spinning nozzles, to which bristle-shaped molding channels join and a plastic melt for the bristles is injected from at least one side of the carrier—the feed side of the melt—through the holes into the channels thereby forming the bristles, wherein the through holes have a minimal width along at least a portion of their length which is ≦3 mm and the ratio between this width and the flow path of the melt resulting from the depth of the through holes plus the length of the channels is ≦1:5. A device for carrying out the method and brush ware produced in accordance with the method is also described.

摘要： In a method for producing a bristle from thermoplastic polymers through injection molding, the molten polymer mass is injected under pressure into a bristle-molding channel of predetermined length having a predetermined cross-section along this length and the channel is vented during injection molding. To produce injection-molded bristles with excellent bending behavior, the magnitude of the injection pressure is adjusted in dependence on the cross-sectional extension of the bristle-molding channel such that a shear flow is generated with high core speed in the center of the molten polymer mass flow and large shearing effect due to wall friction of the molten polymer mass under distinct longitudinal orientation of the polymer molecules at least in the region of the molten polymer mass close to the wall, which is maintained along the channel wherein the channel is simultaneously vented along its length to support maintenance of the shear flow. A device for carrying out the method is also described.

摘要： A bristle with an antimicrobial finish is proposed, which is preponderantly made from thermoplastic material and which is doped with an antimicrobial substance, which, during use, diffuses to the bristle surface. The bristle is manufactured in a multicomponent extrusion process and has at least one first cross-sectional area of a plastic component determining the mechanical use characteristics of the bristle and at least one further cross-sectional area of the other plastic component. The other cross-sectional area or the sum of all the other cross-sectional areas controls the diffusion rate of the antimicrobial substance.

摘要： A method for the manufacture of brushes with a plastic bristle carrier and a bristle configuration of individual or bundlewise-combined plastic bristles is proposed, in that the fastening-side ends of the bristles or bundles are melted to a thickening, thickenings of adjacent bristles or bundles are interconnected by after shaping and displacement of the plastics material and the connections are subsequently embedded in the plastics material of the bristle carrier. The thickenings are shaped by means of a mold to a clearly defined support structure of webs connecting adjacent thickenings and subsequently the support structure and the bristles projecting over the same are embedded by a short length in the plastics material of the bristle carrier. An apparatus for performing such a method and a brush manufactured by such a method are also proposed.

摘要： In a method for the production of brushes consisting of a bristle support and bristles mounted thereon and combined to at least one group having a defined cross-section with at least two different types of bristles, the bristles of a bristle type are combined into a partial group and the partial groups forming a bristle group are combined into said bristle group and subsequently, the bristle group is mounted to the bristle support. The bristles of each partial group are formed in a surrounding guide of a shaping device into a cross-section corresponding to their partial cross-sections in the bristle group, and the partial groups are then combined while maintaining their partial cross-section in the guides to form the cross-section of the bristle group. A device for carrying out this method and brushes produced in this fashion are also described.

摘要： In a method for the manufacture of brushware with plastic bristles, the bristles are extruded continuously as monofilaments, cut to the desired length and fixed to a bristle carrier as a bristle facing either individually or combined into groups. According to the invention, the monofilament after extrusion or the bristles produced therefrom are provided with at least one substantially linear boundary detectable on the bristle facing of the finished brushware as a color-contrasted marking at a distance from the use-side end of the bristles representing the use state. In brushware produced according to this method, at least part of the outer bristles in the bristle facing have a color-contrasted, substantially linear boundary at a distance from the use-side ends of the bristle representing the use state.

摘要： The invention relates to a method for the manufacture of screwlike bristles by extruding monofilaments. In order to provide a method with which screwlike bristles can be inexpensively manufactured in the same way as conventional bristles with an identical, predeterminable quality, a monofilament having a non-circular cross-section is extruded and is prestretched after drawing off, accompanied by a reduction in its cross-section, followed by further stretching, twisting to a screwlike bristle material over at least part of its length and then stabilization by shrinkage. It is possible to extrude a monofilament with an oval or polygonal cross-section or having a core and at least one axially parallel rib. According to a further method, at least two monofilaments are prestretched on drawing off, accompanied by a reduction of their cross-section, followed by further stretching, twisting together to give a screwlike bristle material and stabilization by heat shrinkage.
