A method for arranging a fibre strand on a spinning device of a spinning station, wherein the spinning device is fed the fibre strand in order to produce a spun thread from the fibre strand by means of a drafting unit having a plurality of roller pairs. The roller pairs of the closed drafting unit are each operated, in a manner corresponding to the predefined drafting ratio of the fibre strand, with an introduction speed lower than the operating speed of the drafting unit, the fibre strand is subsequently introduced into the clamping region of an input roller pair of the drafting unit and the drafted fibre strand, after passing through the closed drafting unit and exiting a clamping region of an output roller part of the drafting unit, is subsequently fed to the spinning device.

A spinning machine and method are provided for feeding a sliver end of a sliver deposited in a can to a spinning position of the spinning machine, wherein the spinning machine includes a plurality of adjacently arranged spinning positions and a plurality of cans arranged in at least a first row under the spinning positions. With a sliver gripper of a robot, the method includes seeking the sliver end from one of the cans in an area that includes at least one adjacent spinning position to a spinning position to be supplied. The sliver end is grasped with the sliver gripper and fed to the spinning position to be supplied.

A spinning machine and method separate a sliver delivered out of a sliver can at a spinning station of the spinning machine. The sliver is delivered out of the sliver can with a supply device at the spinning station in a delivery direction to a spinning device, and is guided by a sliver guide between the sliver can and the supply device. The sliver is clamped in the supply device at the spinning station. In order to separate the sliver, the supply device is driven counter to the delivery direction, wherein the sliver is returned by the supply device and, as a result, the clamping of the sliver in the supply device is released.

Smoking articles including filter elements formed from two or more fibrous inputs with different physical properties are provided. The two or more fibrous inputs are provided in the form of staple fibers, which are at least partially entangled with each other to form a mixed fiber sliver. The mixed fiber sliver includes a first plurality of cellulose acetate staple fibers blended with a second plurality of staple fibers comprising a polymeric material different from the first plurality of staple fibers, such as staple fibers of a degradable polymeric material. The entangled fibers of the mixed fiber sliver may be sufficiently separated from one another such that blooming operations typically required in filter element production may not be necessary prior to incorporating the mixed fiber sliver into a filter element. Related methods, apparatuses and mixed fiber products are also provided by the disclosure.

A process and an installation for producing a yarn in accordance with an airjet-spinning method. A carded fibre sliver is subjected to more than three-fold drawing without levelling at a carding machine and deposited in a can (C). At least nine fibre slivers are fed draftfree from cans (C) to a draw frame and subjected to at least 8.5-fold drawing to form a fibre sliver and deposited in a can (C1). The fibre sliver in the cans (C1) is then fed to a spinning station of an airjet-spinning machine.

A textile machine assembly includes a delivery unit and a receiving unit, wherein during operation of the textile machine assembly the delivery unit delivers a sliver to the receiving unit. A sliver storage unit is operatively configured between the delivery unit and the receiving unit to store, at least intermittently, excess sliver between the delivery unit and the receiving unit when a delivery speed of the sliver at the delivery unit is higher than a receiving speed of the sliver at the receiving unit, and to release the stored sliver when the receiving speed of the sliver at the receiving unit is higher than the delivery speed of the sliver at the delivery unit. The sliver storage unit includes a diverting unit that is movable with respect to the delivery unit or the receiving unit, wherein movement of the diverting unit changes a sliver path of the sliver from the delivery unit to the receiving unit.

Yarn delivery device for a twisting or cabling machine having a first deflection roller for deflecting a yarn; a driven godet, arranged downstream of first deflection roller in yarn transport direction; a separator roller, arranged relative to the godet such that a yarn can be laid several times around the separator roller and the godet, said yarn being wrapped around separator roller and godet jointly; and a pitch lever, having a second deflection roller arranged downstream of godet in the yarn transport direction, for deflecting the yarn again. A cantilever, having a third deflection roller, which, in the yarn transport direction, is arranged downstream of second deflection roller and upstream of traversing yarn guide for feeding the yarn onto a take-up package, second deflection roller being arranged on a different side of a vertical plane extending through axis of rotation of the separator roller from the third deflection.

A yarn spinning system has a sliver feeding part feeding a main material used for yarn formation; a main spinning unit in which the spinning procedure of the main materials is performed; suction pipes present in the main spinning unit and enabling the intake of waste fiber formed during spinning; the draft cylinders enabling orderly drawing and smoothing of the main material (fiber) fed into the system; additionally to provide conveying the injected yarns fed into the system to a draft area through the yarn feeding path; and enabling fancy yarn production by conveying the injected yarns to the main spinning unit by being centered on the main material via the yarn guide.
