Abstract
A yarn joined to a previously spun yarn is spun in friction spinning apparatus which comprises two juxtaposed, closely spaced apart twisting members, which define a triangular space, from which air is sucked. Singled stable fibers supplied to said triangular space are twisted together by said twisting members to form a yarn, which is withdrawn by a withdrawing device. A joint-forming portion of a previously spun yarn is provided in said triangular space in the region in which said fibers are supplied to said space, and said yarn is withdrawn while fibers are supplied to said triangular space so as to contact said joint-forming portion. To provide said previously spun yarn with a joint-forming portion which can satisfactorily be joined to the fibers for the newly spun yarn, the previously spun yarn which has been introduced into the triangular space is untwisted between the twisting members in a portion which is spaced from the rear end of said yarn and the latter is tensioned to detach a rear end portion of said yarn from the untwisted portion of the yarn and is removed from the triangular space before or during the supply of fibers to the triangular space.
