Abstract
A condensing zone for condensing a drafted fiber strand is arranged downstream of the front roller pair of a drafting apparatus of a ring spinning machine. The condensing zone includes a stationary sliding surface having a suction slit, over which the fiber strand is transported by a perforated transport belt. The condensing zone is bordered on its exit side by a nipping roller which is disposed on the transport belt. The nipping roller drives the transport belt and is in turn driven by a friction roller. The friction roller is pressed, by means of a loading spring, onto the nipping roller as well as onto a roller of the front roller pair of the drafting apparatus.
