Abstract

A method is provided of producing a core-sheath yarn in which a core yarn is continuously guided in a spinning zone through a gap formed between two adjacent surfaces moving in opposite directions, and staple fibres are fed into the path of the core yarn in such a way that the staple fibres come into frictional contact with the moving surfaces. The core yarn is thereby covered with the staple fibres. The core yarn is guided into the spinning zone at a first defined speed and after covering with staple fibres is drawn off again at a higher second defined speed so as to produce a defined predetermined elastic elongation of the core yarn in the spinning zone. A preferred apparatus for this purpose comprises two rotatable drums (1) each with a porous sleeve in whose interiors are provided air suction devices and between which is defined a narrow gap in which in use the fibres to form the sheath core supplied as individual fibres are collected and spun. A first delivery mechanism (14) is arranged upstream of the drums (1) and a second delivery mechanism (16) is arranged downstream of the drums (1) for the defined supply of the core yarn (3) into the spinning zone and for the defined takeoff of the spun core-sheath yarn from the spinning zone. Means are provided for driving the delivery mechanisms at an adjustable gear ratio. <IMAGE>
