  • Patent number: 7744360
    Abstract: A process for making a toothbrush head comprising widthways adjacent sections, the process comprising the stages of first making the head in an injection moulding process with the sections relatively spaced apart from each other in a widthways direction, then secondly moving the sections of the so formed head relatively spaced closer to each other in a widthways direction. An apparatus for performing the process is also disclosed.
    Type: Grant

  • Patent number: 6919038
    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.
