Abstract
A process is disclosed for a spinning arrangement for dealing with the correction of an end break. During operation, sliver-like fiber material fed to the spinning arrangement is opened to single fibers by means of an opening roller. The single fibers are then transferred in the form of a fiber veil to a suctioned collecting surface, which is driven in the direction of motion of the single fibers. During the transport of the fibers by means of the collecting surface, the fiber veil is condensed to a narrow fiber strand and the condensed fiber strand is spun to a yarn downstream of a nipping line by means of a twisting nozzle. When an end-break occurs, the material feed is interrupted and the fiber strand is suctioned in the area of the nipping line until the collecting surface is free from single fibers. A piecing operation subsequently takes place.
