Abstract
The delivery roller pair are made with continuous uninterrupted cylindrical surfaces so that air flows on the input side converge in the nip and then flow from the central zone thereof to opposite end zones. In addition, the air flows on the output side flow from the end zones towards the central zone. The suction nozzle is disposed downstream and in alignment with the nip so as to receive the fiber material for spinning into yarn.
