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.

A process for making a toothbrush of the type comprising a handle and at least two sections widthways adjacent to each other on opposite sides of a toothbrush longitudinal direction, each section comprising a head part adapted to carry bristles and a neck part by which the head part is integrally connected to the handle, the sections being flexibly integrally linked to each other, wherein the process comprises the stages:
- firstly making the sections in an injection moulding process with the sections flexibly integrally linked to each other and relatively spaced apart from each other in a widthways direction,
- secondly moving the so formed sections relatively closer to each other in a widthways direction so that the head parts and neck parts of the sections come closer together in the widthways direction.
An apparatus adapted to be supplied with a plastics material skeleton of a toothbrush comprising a handle part and at least two sections spaced apart widthways adjacent to each other on opposite sides of a toothbrush longitudinal direction, each section comprising a head part adapted to carry bristles and a neck part by which the head part is integrally connected to the handle, the sections being flexibly integrally linked to each other, the apparatus being adapted to move the head part and the neck part of the sections relatively closer together.
