A method and apparatus of feeding a sliver into a combing section in an open end spinning machine including a feed roller and a combing roller which are arranged side by side on parallel axes within a main body. A pressed sliver is released from the peripherial surface of the feed roller and is guided by the nip surface of a presser which has a curved portion of a radius which is a little larger than that of the feed roller and a flat fiber guide surface extending from the nip surface toward the combing roller substantially linearily relative to the nip surface to guide the sliver fed out from the feed roller to the combing roller. Guide walls are provided extending along the fiber guide surface for limiting the spreading of the fiber bundle passing along the guide surface. The guide surface of the presser is oriented to transfer the fibers to a raking point substantially at a point of contact between the combing roller and a tangent common to the feed roller and the combing roller and lying on the same side of the parallel axes of these rollers. The guide surface is at an angle of from 0.degree. to 15.degree. with said common tangent taken as the reference line.
