<p>A first twisting member comprises a rotary drum. A movable second twisting member defines a triangular-section space with said drum. A pair or withdrawing rollers are associated with one end of said drum. A sliver source is operable to deliver a sliver to said space at the other end of said drum and comprises a draw frame, which directly precedes said space and is operable to draw out said sliver and to hold the drawn-out sliver against rotation. The twisting members are operable to receive flying fibers in said space and to twist said drawn-out sliver and to twist said fibers in said space around said sliver so as to form a yarn. Said withdrawing rollers are operable to withdraw said yarn from said space.</p> |
