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: Provided is a method for manufacturing an interdental cleaning device (1) including a base portion (10) having a handle portion (11) and a core portion (12); and a soft portion (20) having a cleaning soft portion (21), a non-slip portion (22), and connecting portions (23) extending from two sites of the non-slip portion (22) and being connected to the cleaning soft portion (21). The method includes causing a second gate (49) of second molds (40) and (41) for molding the soft portion (20) to open at a position substantially equally distant from positions of two communicating openings (48a) of a non-slip molding space (47) for molding the non-slip portion (22), the two communicating openings (48a) communicating with connecting portion molding spaces (48) for molding the connecting portions (23); and charging the elastomeric material from the second gate (49) into a second molding space (42) for molding the soft portion (20) to fill the molding space (42).

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.

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: 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.
