A joining method wherein fibers of a fiber band are wound around an auxiliary thread threaded into a spinning device and drawn through a spinning cone. The newly spun thread is separated from the auxiliary thread and connected to the end of an upper thread. A spinning device is provided for a jet spinning machine for carrying out such method, comprising a first clamping device for temporary clamping of the upper thread and a second clamping device for temporary clamping of the auxiliary thread. A jet spinning machine for carrying out the method has a mechanism for storing the auxiliary thread and the newly spun thread, a mechanism for separating the auxiliary thread from the newly spun thread, and a splicing mechanism for connecting the newly spun thread to the upper thread, all arranged only on at least one operating carriage displaceable along multiple spinning stations.

A drafting arrangement for a spinning machine, comprising at least one pair of feed rollers, one pair of central rollers and a pair of withdrawal rollers, wherein the lower rollers of the drafting arrangement are configured as roller segments, which are rotated by single-motor drives, and the upper rollers are mounted in a pendulum carrier. The lower roller drive () at least of the pair of central rollers () is arranged together with its lower roller (A) in a bearing device () in such a way that, after opening of the pendulum carrier () receiving the associated upper roller (B), the lower roller (A) and its drive () can easily be removed from the bearing device () in the direction of the pendulum carrier ().

An opening arrangement for an open-end spinning device with a rotating opening roller having opening elements stationarily arranged on its circumference for opening a delivered sliver into individual fibers and for combing out the fibers at a comb-out point. The opening roller has a mechanical stripping arrangement that rotates along with it. The stripping arrangement includes ejectors that are pivotably fastened on the opening roller. Each ejector is arranged between the opening elements and extends over the opening roller transversely in relation to the direction of rotation. The ejector strips combed-out fibers off the opening elements and improves the opening of the opening roller as well as the transfer of the fibers from the opening roller. The opening arrangement is advantageously employed with an open-end spinning frame.

A spinning device for producing a spun yarn by a circulating air flow in a housing has an adjustment device ( ) for controlling the angular position of the fiber ends wrapped around a spindle head, and in turn, the angular position of the fibers wrapped around the produced yarn, by adjusting a linear component of an air flow into the spinning device as a function of the yarn withdrawal speed, whereby a yarn is produced of a required yarn strength even during a spinning start phase in the process of making the spun yarn.

Spinning device for producing a spun yarn by means of a circulating air flow

A device for producing spun yarn by means of an airflow acting in a twisting manner on the fibers of an untwisted sliver (,) as the sliver is being conducted into and through a spindle assembly (,). The spindle assembly (,) comprises a spindle head portion (,) which conically tapers toward a spindle inlet opening (,) and is rotatable independently of a spindle core portion (,) through which the yarn is withdrawn. The device suppresses any tendency of the yarn strength to decrease at high, increasing numbers of spindle revolutions.

Device for producing spun yarn

A device for producing spun yarn by means of an airflow acting in the area between a sliver guide and a spindle (,) on fibers of a non-twisted sliver (,) drafted and delivered by a drafting arrangement in order to twist the fibers. Thereafter, the sliver (,) is passed through the spindle (,). Outside of an imaginary center line (,) of the traveling sliver (,), the sliver guide is arranged such that the fibers are passed along the inward lying surface of the sliver guide. The sliver guide comprises fiber guide elements (,) spaced apart from each other, which permit the free passage of a core fiber bundle. An improved spinning process, along with high productivity and increased yarn strength is possible by means of the device of the invention. The spinning device can be manufactured and operated cost-effectively.
