The machine (1) has section-wise arranged spinning areas positioned next to each other on both sides of a machine longitudinal axis. Each area has suction pipes (10) in an area of a stretching unit arrangement (5) attached at a negative pressure-subjectable filter device (20) by a suction channel (12). The pipes are connected to a negative pressure source i.e. electric motor driven ventilator, or the channel by actuating a defined controllable slider element (13) that is engaged into a channel part (11), where the negative pressure source is arranged at the channel part. |
