ABSTRACT:
In apparatus for making a yarn, two closely juxtaposed suction drums are rotated in the same sense and have suction zones which define a generally triangular space. A drawframe supplies a roving to one end of said triangular space. Withdrawing means are provided for withdrawing a yarn formed from said roving from the other end of said triangular space. Means are provided for supplying covering fibers to a predetermined length zone of said triangular space in a direction which is transverse to the axes of said drums so that said covering fibers cover said roving. To improve the twisting of the roving, means for twisting the roving are provided between the drawframe and said predetermined length zone of said triangular space.
