Abstract
An apparatus for winding a filament onto a former includes one or more filament supply bobbins mounted on an annular carrier for rotation about a first axis for receiving a plurality of windings of the filament, and a translation device for moving the former relative to the carrier along a path which passes through the carrier thereby enabling the filament to be wrapped around the former. A guide member guides the filament from a respective bobbin to the former, the guide member defining a radially outward facing cylindrical surface. The apparatus reduces bending of the filament as it is wound onto the former.
