摘要： A friction spinning apparatus comprises a combing roller (19) for opening and feeding fibers in a duct (16, 15) to a throat (Q) formed between the outer surfaces of a pair of perforated and smooth surface drums (10, 12) arranged in parallel to each other and rotating in the same direction. A yarn (Y) formed at the throat (Q), by frictional contact between the fed fibers and the surfaces caused by a suction force, is withdrawn along the throat (Q). The duct (15, 16) is arranged to feed the fibers in an air stream having a direction inclined to the yarn axis (YL) and has a nozzle (17) in the form of a double pipe in the midportion thereof. A compressed air is ejected from the annular slit (17a) between the inner and outer pipe of the nozzle (17) to drag the fibers out from the nozzle (17) to cause them to stretch, whereby the fibers can be conveyed on the throat (Q) in the stretched state.
