ABSTRACT:
Bristle articles can be manufactured in that the bristle carrier and optionally the ends of the bristles are melted and brought together under pressure, or the bristles are introduced into an injection or foaming mould for the bristle carrier and are embedded in the bristle carrier material by injection moulding or foaming. The cycle time of these processes is extremely long as a result of the thermal processes (heating, melting, injection moulding, cooling). It is possible to significantly reduce the same in that the tools for holding or producing the bristle carrier on the one hand and the clamping devices for the bristles on the other are moved on closed paths and the clamping devices at at least one common station are transferred to the path of the tools and at least during the thermal processes are jointly moved with the tools and are subsequently returned to their movement path.
