Abstract
Method of preparing fibers fed from a fiber-loosening device into a wedge-shaped spinning zone of a friction spinning machine having friction elements moveable relative to one another, which includes feeding a fiber-laden carrier-air flow having a component directed parallel to the wedge-shaped spinning zone tangentially to one of the friction elements at a location outside the wedge-shaped spinning zone and in a direction opposite the direction of movement of the one friction element, simultaneously exerting holding forces on the fibers and flinging the fibers against the moving surface of the one friction element so that the fibers are stretched out and held fast thereon, conveying the fibers in held-fast condition thereof into the wedge-shaped spinning zone, rolling the fibers therein and integrating the fibers into a yearn, and drawing-off the thus-formed yarn.
