<p>Method for manufacturing brush bodies for tooth brushes by injection moulding, the brush body comprising at least two components (5-9), whereby said method comprises the steps of forming at least one first injection moulding piece (25) by injecting a first component (5) in a first mould (3); transferring the first injection moulding piece (25) by means of a transfer part to a second mould (7); and forming at least one second injection moulding piece (26) by injecting a second component (9) onto the first injection moulding piece (25) in said second mould (7); said method also comprising the steps of forming holes (35) in the first injection moulding piece (25) for inserting brush hair; characterized in that during the forming of the second injection moulding piece (26); a series of pins is brought at least partially into at least a number of the holes (35) so that the holes (35) remain open, in other words, are not filled with the second component (9) and/or are supported against deformation. <IMAGE></p> |
