Abstract
A draft device is provided with a rotatable porous roller and a suction tube for establishing a negative pressure within the porous roller. A pneumatic spinning apparatus is provided with a spindle and a nozzle for exerting a whirling air current on a fiber bundle from the draft device. A waste transport pipe is provided for circulating waste discharged from the spinning apparatus back to the porous roller. Waste discharged from the spinning apparatus is thereby recycled to join with the fiber bundle from the draft device.
