Abstract

Two yarn components (e.g. wool fibre strands) are converged at a convergence guide after pref. being fed through the same drafting device and a ply-twist is inserted into the strands by e.g. a ring and traveller downstream of the convergence guide such that the twist runs back to the convergence guide. A device is provided between the convergence guide and ring and traveller to intermittently prevent the twist running back to the convergence guide so as to insert a twist into the individual strands; pref. the strands pass between a plane presser roller, and a co-operating roll which has a cut-away portion so that the strands are intermittently nipped and freed on rotation of the co-operating roll. A twist is inserted into the yarn components and the components ply twisted together in a single operation.
