A method of manufacturing comingled yarn of carbon and thermofusible fibres comprises the steps of: feeding a tow of thermofusible fibres from a spool to a blending roller and between the spool and the blending roller, spreading the thermofusible tow; feeding a tow of carbon fibres from a spool to the blending roller; spreading the carbon fibre tow between the spool and the blending roller by applying a flow of air over the tow to urge the tow against a supporting surface over which the carbon fibres pass on their way to the blending roller; combining the thermofusible and carbon fibre tows at the blending roller.
