Abstract: A process is claimed for manufacturing a vacuum cleaner brush fibre bristle retaining strip comprising a plastic-backed pile fabric (1) consisting of a base fabric (3) of warp and weft fibres into which polymer bristle fibres (2) are integrated. Process stages involve: (a) selecting a strip of pile fabric(1) with integrated polymer bristle fibres whose area corresponds to the number of fibre retaining strips to be manufactured; (b) continuously extruding a thermoplastic plastic strip (5) from a slit die at constant speed; (c) bringing the pile fabric strip (1) and plastic strip together and applying pressure while the thermoplastic is still soft to achieve a mechanical integration between both strips; (d) cutting or punching individual retaining strips from the plastic-backed pile fabric after it has cooled. Preferably the pile fabric (1) may: (a) already have preformed angled bristles; (b) have bristles fibres normal to the base fabric which are set in an angled position when the plastic strip (5) and pile fabric are combined: (c) have bristles normal to the base fabric which are then angled under heat and pressure before or after combining the pile fabric and plastic strip, e.g. by rolling or ironing. The bristle fibres are set into the thermoplastic when the two strips (1,5) are pressed together. Additional chemical integration of both strips (1,5) can be achieved by the correct selection of materials, process temperature and pressures.
