Abstract
A condensing zone lies downstream of the front roller pair of a drafting unit of a spinning machine, in which condensing zone a drafted fiber strand is condensed. The condensing zone comprises a sliding surface having a suction slit, which sliding surface serves as a guide for a circulating, perforated transport belt. The transport belt transports the fiber strand to a nipping roller, which presses the fiber strand and the transport belt against the sliding surface. The nipping roller is connected to a drive, from which drive said nipping roller can be cut off in age the case of a break in the transport belt.
