Abstract
A condensing zone is arranged downstream of the drafting apparatus of a ring spinning machine, through which condensing zone an air permeable transport belt transports the drafted fiber strand. A cleaning element is arranged at the transporting element, which cleaning element takes the form of, for example, a cleaning roller, and which is pressed using a light pressure onto the transporting belt. The rotation direction of the cleaning roller preferably runs in the opposite direction to the direction of motion of the transport belt. The driven bottom roller of the front roller pair of the drafting apparatus can serve as a cleaning roller.
