Abstract
Method and apparatus are disclosed relating to forming yarn by 'vacuum spinning'. A spinning nozzle assembly is provided which includes two axially aligned sections, each formed with a through passageway. Adjacent facing surfaces of the sections define a continuous radial slot through which air flow may be directed. The axially aligned sections of the nozzle are, in one exemplary embodiment, telescopically received within a sleeve mounted for rotation within a housing. The nozzle sections may be adjusted axially relative to each other to alter the dimension of the radial slot as desired, for example, in accordance with a predetermined yarn count.
