<p>A machine for manufacturing a unitary glass fibre reinforced body shell includes a carriage (52) which is movable along the mold (300) and a turntable (180) which is mounted on a carriage (54) for rotation about a first axis (174) extending in the direction of longitudinal movement of the carriage (52). An arm (210) is slidably mounted on the turntable (180) for radial movement and a dispenser (240) is located on the arm for dispensing glass fibre reinforced resin onto the surface of the mold (300). A guidance system (150) is provided which interconnects the turret (130) and the slidable arm (210) and is operable to cause the arm (210) to reciprocate with respect to the turret (130) in a radial direction to maintain a substantially constant length of trajectory extending between the dispener (240) and the wall of the mold. A drive system is provided for rotatably driving the turret (130) about the axis. The carriage (50) is normally stored on a mobile end cap (10) which may be moved from one mold to another and serves to close one end of the mold. A canopy (80) is mounted with one end connected to the mold (300) and the other end connected to the dispenser carriage (52) such that as the dispenser carriage moves along the mold, the canopy (80) is deployed to cover the open upper end of the mold to form an enclosed chamber from which fumes may be extracted. The method of forming the required body shell includes the steps of dispensing a coating of glass fibre reinforced resin onto the forming surface of a mold (300) while moving the dispenser (240) along successive longitudinally displaced U-shaped paths which traverse the forming surface to form a continuous coating covering the top and side forming walls of the mold cavity. The further step of compacting the coating by applying a compactor (250) to the inner surface of the coating and moving the compactor (250) along the same path as that followed by the dispenser (240) at a point located downstream from the dispenser.</p> |
