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 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.
