Title: Apparatus of a spinning machine for condensing a fibre strand

Abstract: A condensing zone for condensing a drafted, still twist-free fiber strand is arranged downstream of a front roller pair of a drafting unit of a spinning machine. An air-permeable transport belt transports the fiber strand through the condensing zone. The transport belt slides hereby over a stationary sliding surface, in which a suction slit of a suction channel is located. At the end of the condensing zone, the fiber strand is pressed with the transport belt by a nipping roller to the sliding surface. The nipping roller as well as the front pressure roller of the drafting unit are supported in a top weighting arm. A separate pressure spring is arranged each for the top pressure roller and for the nipping roller. It can be provided that the nipping roller is arranged at a holding device, which can be swivelled around a swivel axle, which lies coaxially to the axle of the front pressure roller.
