A spinning device for producing a twisted thread formed at least partially of spinning fibers, includes a flow generator having an air inlet and an air outlet, at least one rotating perforated drum having a given axis, a suction device disposed in the drum, the suction device having at least one suction opening disposed substantially parallel to the given axis and connected to the air inlet of the flow generator, another drum disposed outside the first-mentioned drum opposite the suction opening for forming a spinning wedge from flying fibers, a fiber loosening device for loosening fibers and conducting an air transport current, a fiber conduction channel for conducting the flying fibers and the air transport current from the fiber loosening device to the spinning wedge, means communicating with the fiber conduction channel for increasing the air transport current flowing through the fiber conduction channel, and an air conduction line connected from the air outlet of the flow generator to the air current increasing means.
