摘要： An overend take-off crosswound bobbin and a method for its production are designed in such a way that the density of the finished crosswound bobbin is increased and the run-off characteristics during further processing are optimized. For this purpose, in one variant parallel windings are introduced at intervals. In another variant, when the bobbin diameter is small the yarn is wound on at a smaller pitch angle than for a larger diameter. Furthermore, a traversing stroke which is reduced by comparison with the bobbin width is displaced along the bobbin width.

摘要： An air jet spinning arrangement includes an essentially hollow cylindrical vortex chamber, whose peripheral wall forms a supporting surface for a peripheral surface of a rotationally symmetrical insert in the running-in area of the staple fiber strand. A number of air jet slits are worked into the peripheral surface of the insert, which air jet slits are completed to form closed compressed air channels by way of the supporting surface. The nozzle-like mouths of the compressed air channels are arranged on the front side of the insert facing the vortex chamber. The design of the air jet slits resemble a multiple-start thread.

摘要： A process and an arrangement for re-starting a previously interrupted spinning process in a spinning arrangement is provided. The arrangement includes a drafting unit which can be shut down and also an airjet unit including a vacuum chamber. For the purpose of removing an initially inhomogeneous fiber stream, a staple fiber strand, delivered by the re-operating drafting unit, is temporarily suctioned as waste via a deflecting device after it has left the drafting unit. Only then, when a homogeneous fiber stream has formed, is the staple fiber strand joined with a thread which is transported through the airjet unit. The inhomogeneous fiber stream is removed with the aid of the low pressure in the vacuum chamber.

摘要： An arrangement for manufacturing a spun thread from a staple fiber mass includes a feed channel having an outlet opening for feeding the fiber mass, and a yarn withdrawal channel having an inlet opening. In order to generate a rotating current around the entry opening of the yarn withdrawal channel, a vortex chamber is provided with compressed air nozzles. An air evacuation duct surrounds, essentially ring-like, a stationary, spindle-shaped component which forms the yarn withdrawal channel. The feed channel extends in a meandering manner and includes fiber guiding surfaces, which are designed in the form of deflecting edges, between which the staple fiber mass is without support.

摘要： A flexible sealing ring is arranged at an opening roller of an open-end spinning machine which rotates in a chamber of a housing connected to a vacuum source, which sealing ring is supported concentrically to the opening roller in the housing. In order to seal the chamber against the open atmosphere, the sealing ring comprises a sealing lip, to which a sealing surface of a collar of the opening roller is arranged. The sealing ring is disposed, under the action of the pressure drop present between the open atmosphere and the chamber, on a stopping surface which determines the operational position of the sealing ring, which stopping surface is itself arranged preferably at the housing, while, however, in some embodiments, it is arranged at the opening roller itself. The sealing lip defines the smallest diameter of the sealing ring, which is larger than the diameter of the combing structure of the opening roller.

摘要： A yarn package and a method and apparatus for producing the same are disclosed, and wherein the package is composed of a yarn wound in layers of decreasing axial length so as to define a central cylindrical portion and opposite end portions. In order to protectively shield the exposed ends of the yarn layers within at least one of the tapered end portions, the outermost layer is extended so as to overlie and entirely cover such one tapered end portion. In addition, selected intermediate yarn layers may be extended axially a distance sufficient to overlie and cover essentially all of the underlying layers on such one end portion to protect and stabilize the underlying yarn layers.
