[Also in Division B5] Brittle fibre strands 8 (e.g. of glass fibre) are fed into a pugmill having a pair of rotatable mixing members 2 by which the strands are broken and distributed evenly into thermoplastic material the components of which are metered at 5; the length of the broken strands is said to be determined by the distance of their point of introduction 7c from the outlet 6. As shown the screw housing 1 is made in sections and has a longitudinal opening 11 along which the fibre inlet 10 can be adjusted, the remainder of the opening 11 being closed by members 9'. Alternatively there may be a plurality of fibre inlet openings, the ones not in use being closed by a cover. The material may be extruded as strands, slabs or granules.
