Abstract: Fibre loosening device for a spinning unit of a spinning machine. The invention relates to a fibre loosening device for a spinning unit of a spinning machine. Before entering the fibre separating area, the sliver is longitudinally separated into fibre sections fed to a separating region, i.e., to helix-like arranged functional lines on the fibre separating roller, such feeding being non-simultaneous but sequential. The division into the fibre sections is initially carried out by means of protrusions defining grooves therebetween on a condenser, the axial distance between these grooves not being an integer multiple of the helix lead width of the functional lines on the fiber separating roller. The arrangement provides for reducing periodical irregularities of the fibres for the subsequent spinning process.

Abstract: A device for winding conical yarn packages, particularly in textile machines with a constant yarn delivery speed, which eliminates the difference between the yarn delivery speed and the yarn winding speed by using a prolate spheroid drive means for the yarn package. The drive means is supported on a common shaft by means of a tilting joint and a carrier there being a swinging actuator associated with at least one end face of the drive means, the swinging motion of the actuator taking place within a plane passing through the axis of the common shaft.

Abstract: Method of spinning staple fibers by imparting false twist to a continuous fiber bundle. The continuous fiber bundle is formed by a successive doubling of separated fibers, and is thereupon twisted by means of a false twisting element, the separated fibers being distributed along the twisted length of the fiber bundle, as well as along the untwisted section of the continuous fiber bundle.

Abstract: An open end spinning device having a rotating chamber to which discrete fibers are fed and in which the fibers are spun into a continuous yarn which is removed from the chamber. The fibers are supplied through a duct formed in a parallelpiped body, which duct is directed at the opening of the spinning chamber. The fibers are engaged and deflected with respect to the direction of rotation of the spinning chamber by means interposed between the duct and the chamber so that each fiber is braked at its rear end and caused to enter the chamber in an elongated fashion oriented with respect to each of the other fibers.
