Abstract
Apparatus for making a yarn comprises two juxtaposed, closely spaced apart suction drums, which rotate in the same sense, and a fiber-guiding duct, which protrudes into the triangular space between the suction drums and serves to supply single fibers. In order to ensure a uniform tying of the single fibers into the yarn as it is formed, the length of the outlet opening of the fiber-guiding duct exceeds the average length of the longest fibers to be processed. Besides, the distance from the outlet opening of the fiber-guiding duct to the common diametral plane of the suction drums is such that the arc length of the periphery of each suction drum from the point which is nearest to said outlet opening to said common diametral plane is not in excess of 0.5 radians.
