Title: Process and apparatus for spinning textile fibres

Abstract: A process and apparatus for spinning textile fibres in which the separated fibres are conveyed in an air stream into a confined space between two contra rotating friction discs (6,7). The air stream enters through an opening (5) in one disc (6) and passes through a permeable collecting surface (9,13) into a static suction exit passage (15) located within the other disc (7). The fibres are drawn off at right angles through the annular gap between the two discs and in doing so are twisted into a roving (16).
