A reinforcing medium comprises a web, tissue or mat formed of continuous glass filament yarns entangled with glass fibre monofilaments. Threads of molten glass 1 fall on to a rotating drum 2 and solidify, the monofilaments so formed break away from the drum 2 assisted by a scraper 3 and are entrained in an air stream to be carried through a hood 5 on to a conveyor 7. The air stream may be formed by the rotation of the drum 2 within a shroud 4. Fed into the air stream from creels 8 are continuous glass filament yarns 9 to be carried through the hood 5 for deposition on the conveyor 7. During their progression the yarns 9 become entangled with the monofilaments, particularly within the hood 5, so that the deposited fibres are an entangled tissue on the conveyor. The tissue on the conveyor is coated with a resin bonding agent and cured to provide a substantially stable mat suitable for the reinforcement of plastics mouldings. <IMAGE> |
