Abstract
Apparatus for making a yarn comprises two juxtaposed, closely spaced apart twisting drums, which rotate in the same sense about parallel axes and at least one of which has a suction zone, which faces the generally triangular twisting space defined by said twisting drums between them. A fiber-guiding passage extends into said generally triangular twisting space at an oblique angle to the axes of said twisting drums and has an outlet opening, which extends along said axes and serves to supply fibers which are to be twisted together to form a yarn. In order to increase the strength of the yarn, each suction zone is enlarged in width adjacent to one end of the outlet opening of the fiber-guiding passage.
