Abstract
A draft free condensing zone for condensing a drafted fiber strand is provided between a front roller pair of a drafting unit of a ring spinning machine and a delivery roller pair arranged downstream thereof. The apparatus for condensing comprises an air-permeable und suctioned sliding surface which is in contact with the fiber strand, under which sliding surface is located a suction slit which is stationarily arranged and extends essentially in transport direction of the fiber strand. The sliding surface is the front surface of a rotating disc, whose rotational axle extends essentially perpendicular to the transport direction of the fiber strand.
