To provide a method for forming a twisted yarn from fiber comprising the fiber untied by an opening roller, and extending on an fiber accumulating face in parallel, and further to provide an apparatus therefor.

A fiber bunch placed on a fiber-accumulating face are guided from a placing region as a roving without twisting, and the guided roving is twisted and fixed at the first time in the following twisting region in the method for forming a twisted yarn. For the purpose, the apparatus is formed so that the fiber-accumulating face may be a rotationally moving face 12, and has narrow groove-shaped holes on the periphery. The apparatus also has at least one ventilation opening 21 extending upward so as to be adjusted to the holes of the rotationally moving face, and a device for imparting twist to the front side of the rotationally moving face, and connected thereto.
