Abstract: A method and an apparatus for spinning and crimping a synthetic multifilament yarn, wherein a filament bundle is spun from a polymer melt and compressed to a yarn plug. The yarn plug is advanced at a cooling speed and cooled within a cooling zone in a moving cooling groove. After cooling, the yarn plug is disentangled to form a crimped yarn, with the latter being wound to a package. The method of the invention also provides for selecting the length of the cooling zone and the cooling speed of the yarn plug such that the yarn plug is cooled in the cooling groove over a period of at least 1 second. To this end, the apparatus of the invention includes a cooling groove, whose width is dimensioned such that the yarn plug can be advanced in meander form in a plurality of superposed layers.

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.
