Abstract
A composite yarn is spun in a tapering gap between two suction drums which define suction zones adjoining the gap and facing each other. A yarn core is supplied to the gap between the facing suction zones from a bobbin at one end of the gap and flying fibers are supplied into the gap between the facing suction zones. Yarn drawoff rolls at the opposite end of the gap withdraw spun yarn while holding it against rotation, the flying fibers being twisted and wound around the yarn core in the gap between the facing suction zones to be spun into the composite yarn when the drums are rotated in the same sense.
