Abstract
The present invention relates to a method of producing thick-walled brushes, in particular toothbrushes, with a grip piece and a brush head supporting bristle filaments. In order to increase the productivity, the method mentioned at the start is further developed by the present invention in that a core produced in a first injection molding cycle is coated with a plastic component in at least one subsequent injection molding cycle so as to form a multi-layered grip piece.
