Provision is made here that the web has at least one protruding web rib, and/or that at least one rib is formed on the outer face of the sheath.

Abstract: A polycrystalline material having low mechanical strain is provided. The polycrystalline material includes one or multiple layers of a first type and one or multiple layers of a second type. The layers of the first type and the layers of the second type each include at least one polycrystalline material component. The layers of the first type have a smaller average crystal grain size than the layers of the second type, a layer of the first type and a layer of the second type being situated, at least in part, one above the other in an alternating sequence, and it being the case for the transition between the layers of the first type and the layers of the second type to be abrupt or continuous.

Abstract: An index plate molding device configured to produce a multi-component part including an injection mold having an injection parting surface, and an ejection mold having an ejection parting surface in selective contact with the injection parting surface to form an ejection parting line therebetween. The index plate molding device also includes an index plate movable relative to the injection mold and the ejection mold, where the index plate includes an index parting surface in selective contact with the injection parting surface to form an index parting line therebetween, and where the index plate is shaped such that the outer surface of the first component of the multi-component part is available for overmolding on both sides of the index parting line when the first component is coupled to the index plate.

Abstract: An interdental cleaner for cleaning interdental spaces includes a cleaning portion for interdental cleaning and a handle portion connected as a grip to the cleaning portion by a flexible neck portion.

Abstract: An interdental cleaner has a rod-shaped carrier formed of plastic, which has a structuring with structural elements radially protruding from the carrier on at least one section of an axial length thereof. The carrier is twisted in at least one part of the section having the structuring together with the structuring about a carrier longitudinal axis.

Abstract: A method for manufacturing an interdental cleaner includes providing a rod-shaped carrier made of plastic, into which laterally protruding bristles are embedded. In this case, a filament array formed of a plurality of filament strands is inserted into a holding cassette and is fixed in a predefined alignment in the holding cassette by means of a holding device. The holding cassette is then inserted into an injection-molding device and the filament array is extrusion-coated with plastic in the injection-molding device, forming a plurality of rod-shaped carriers arranged spaced apart next to one another. Finally, the filament strands forming the filament array are separated at least in the sections located between adjacent rod-shaped carriers. In addition, a device for carrying out the method is provided.

Abstract: An interdental cleaner has a rod-shaped carrier consisting of plastic, which has a cleaning device in an axial end area. The cleaning device comprises at least one fabric part, which extends in the direction of a longitudinal axis of the carrier and which has mutually intersecting thread systems with warp threads and weft threads. Provisions are made for the fabric part to be connected to the carrier and to radially project from same, wherein thread systems or the warp threads, on the one hand, and the weft threads, on the other hand, extend at an angle in the range of 20° to 70° to the longitudinal axis of the rod-shaped carrier and pass through the rod-shaped carrier.

Abstract: A manufacturing method is provided for a piezoelectric layer arrangement and a corresponding piezoelectric layer arrangement. The manufacturing method includes the steps: depositing a first electrode layer on a substrate; depositing a first insulating layer on the first electrode layer; forming a through opening in the first insulating layer to expose the first electrode layer within the through opening; depositing a piezoelectric layer on the first insulating layer and on the first electrode layer within the through opening; back-polishing the resulting structure to form a planar surface, on which a piezoelectric layer area, surrounded by the first insulating layer, is exposed; and depositing and structuring a second electrode layer on the first insulating layer, which contacts the piezoelectric layer area.

Abstract: A device for cleaning the mouth or teeth has a rod-shaped support, on one axial end of which an interdental cleaner made of a flexible plastic is arranged. A brush-like cleaning part made of a flexible plastic, and having a plurality of protruding cleaning elements, is arranged at the opposite axial end of the rod-shaped support. In addition, the rod-shaped support has a grip portion made of a flexible plastic and arranged preferably in the central area of the axial length of the rod-shaped support. Provision is made that the grip portion is connected, via at least one connecting portion, to the interdental cleaner and/or to the brush-like cleaning part so as to form a one-piece structure.

Abstract: An interdental cleaner with a rod-like support which has a cleaning device in an axial end region. The cleaning device includes a cover on the support made of a soft-elastic plastic, and structuring is formed on the outside of the cover having a plurality of fingers protruding with radial components from the cover, which fingers are made of the same material as the cover and are connected as one piece thereto. The structuring additionally has a bristle edging with a plurality of bristle bundles protruding with radial components from the cover and/or individual bristles which are each formed from pre-produced bristles embedded in the cover and/or in the support.
