Abstract
A device for the manufacture of a spun thread from a fiber sliver includes a fiber conveying channel with a fiber guidance surface. A yarn guidance channel includes an inlet mouth aperture disposed such that the fiber guidance surface guides fibers to the inlet mouth aperture. A fluid generating device creates eddy currents around the inlet mouth aperture to incorporate individual fibers into an end of a yarn being formed in the yarn guidance channel. The fiber guidance surface includes a fiber delivery edge having a shape and disposed relative to the inlet mouth aperture such that the fibers are guided over the delivery edge and conveyed to the inlet mouth aperture in an aligned generally flat planar formation.
