ABSTRACT:
A process and an arrangement for the spinning of staple fibers into a yarn is disclosed in which sliver-shaped fiber material is opened up into individual fibers which are fed to a collecting surface which moves at a speed which corresponds to at least the feeding speed of the individual fibers. The collecting surface conveys the fibers to a withdrawal point with the collecting surface tapering between the feeding point and the withdrawal point. The collecting surface operates to bundle the fibers during the conveying to the withdrawal point to form a fiber composite which is withdrawn at the withdrawal point while receiving a twist. It is provided that the withdrawal of the fiber composite at the withdrawal point takes place in a direction which corresponds essentially to the conveying direction of the fiber composite on the collecting surface, a withdrawal speed being provided which is essentially equal to the conveying speed of the collecting surface.
