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 airjet spinning arrangement includes a fiber feed channel, which runs into a vortex chamber, and a fiber withdrawal channel, which exits out of the vortex chamber. The fiber withdrawal channel is arranged in a spindle-shaped component, which can be moved away from the fiber feed channel by a moving device. In order to clean the area of the entry opening of the thread withdrawal channel, a cleaning channel is provided, which is directed against the spindle-shaped component and is connected to a pressurized air source. The cleaning channel runs into a ring channel, which surrounds the spindle-shaped component. A first exit opening of this ring channel is designed so that it forms a ring opening surrounding the spindle-shaped component and is directed against the spindle shaped component when the spindle-shaped component is moved away from the fiber feed channel. A second exit opening of the ring channel runs via an intermediary channel into the thread withdrawal channel and is directed against the entry opening of the thread withdrawal channel. Thus, the area of the entry opening maybe cleaned from the inside and the outside in the case of maintenance.

摘要： A twin unit has two drafting devices for drafting fiber strands and is applicable in a spinning machine. The twin unit includes a common housing for the two drivable drafting devices, whereby the housing is detachably mounted in a machine frame. The drafting devices include a number of drivable bottom rollers and are arranged essentially mirror-symmetrical to one another. Each bottom roller has an area which drafts the fiber strand and is characterized in that the bottom roller has two bearing points. The two bearing points of each bottom roller are arranged one on either side of the area which drafts the fiber strand. In one variation, at least two opposite bottom rollers may form a bottom roller pair, in which the bearing points facing to the plane of symmetry of the twin unit are taken up in a joint bearing take-up. In addition, a top roller in the form of a twin pressure roller may be assigned to a bottom roller pair.

摘要： A process for preparing a piecing operation in an air jet spinning arrangement is described. The air jet spinning arrangement comprises a drafting device, whose main drafting zone is bordered on its entry side by an apron roller pair and on its exit side by a delivery roller pair. The apron roller pair is connected to a first drive, the delivery roller pair to a second drive. When the spinning process is interrupted, the delivery of a closed staple fiber strand is stopped in the main drafting zone and a new starting end of the staple fiber strand is created. This new starting end is to be pieced together with an end of a thread already spun. To create a new starting end of the staple fiber strand suitable for piecing, the apron roller pair and the delivery roller pair are each controlled separately when the spinning process is interrupted and are shut down one after the other, in such a way that in the main drafting zone a new starting end of the staple fiber strand is formed.

摘要： A holding device for a twin pressure roller of a drafting unit includes a number of bottom rollers. The twin pressure roller includes a stationary axle and two rotatably supported upper rollers. The holding device includes at least one positioning element assigned to the axle of the twin pressure roller and at least one force transmission element, wherein the positioning element is arranged in the area of the center of the axle of the twin pressure roller and thus permits the twin pressure roller to move in a pendulum fashion around the center. The holding device, together with the twin pressure roller may be lifted from the bottom roller. At least one catch bearing for approximate positioning during placement on the bottom rollers is assigned to the twin pressure roller. It may further be provided that the force transmission element is arranged separately from the positioning element and that the catch bearing is integrated into the force transmission element.

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.
