A centrifugal spinning apparatus, comprises a plurality of drawing mechanisms for simultaneously producing a plurality of fiber tows and a plurality of spinning units forming an assembly of such units operating in synchronism, each spinning unit being associated with a respective drawing mechanism and comprising a pair of centrifugal spinning pots associated with respective temporary storage bobbins. Each drawing mechanism alternately supplies two spinning pots. On changing pots, the yarn is severed and its end is picked up by a temporary storage bobbin. A carriage, displaceable along a guide, carries a yarn suction arm pivotally mounted about shaft, a joining device, a reserve yarn bobbin system, and a take-up bobbin. The carriage is moved opposite storage bobbins of the different spinning systems associated with the several drawing mechanisms. The reserve yarn bobbin system ensures the continuity of the winding of the yarn on the bobbin during the displacement of the carriage and the joining of the two ends of the yarn by the joining device so that a continuous yarn is produced on the take-up bobbin and wound at a speed which is a multiple of the speed of each drawing mechanism.
