A filament winding apparatus comprises a former 14 rotatable about an axis 16, a resin bath 20,and an adjustment pulley 24 rotatable about an adjustment axis 26, rotation of the former 14 about its axis 16 causing a filament 12 to be drawn through the resin bath 20 and around the adjustment pulley 24 to be wound upon the former 14, wherein the adjustment pulley 24 is adjustably mounted to permit displacement of the adjustment axis to vary a length of filament 12 located between the resin bath 20 and the former 14, a motor 40 being operable to displace the adjustment axis 26 of the adjustment pulley 24. A control method suitable for use with the apparatus is further disclosed wherein data representative of the profile of the former and the rotary position thereof are used to control the displacement of the adjustment axis of the adjustment pulley. |
