Abstract: A method for automatically piecing a thread at a workstation of a textile machine, includes seeking an end of the thread on a surface of a bobbin with a suction nozzle and unwinding the thread from the bobbin counter to a regular draw-off direction of the thread and sucking the thread into the suction nozzle. The bobbin is driven in a direction of reverse rotation with a drive. A thread loop is draw-opened in the thread and moved towards a piecing unit via movement of a feeder unit. The bobbin is driven in the direction of reverse rotation during the drawing-open of the thread loop such that the thread is unwound from the bobbin. A speed of reverse rotation of the bobbin is coordinated with movement of the feeder unit.

Abstract: A monolithic body having angle scaling is rotatable about an axis to measure the rotational position of a machine part. The body has a first annular region which has a flange-type configuration for connection to the machine part, and a second annular region on which the angle scaling is arranged, as well as a crosspiece region. The crosspiece region is arranged between the first annular region and the second annular region. The crosspiece region has a geometrical extension in the direction of the axis which is at least three times smaller than the greatest geometrical extension of the second annular region in the direction of the axis (Z).

Abstract: A method for producing and mounting a body having an angle scaling includes: applying three markings to the body, the markings being set apart from each other; adjusting the body relative to a support device, so that the distances between the markings and a point, which is permanent relative to the support device, are equal; applying an angle scaling to the adjusted body; dismounting the body from the support device; and mounting the body, provided with the angle scaling, on a machine part so that the distances between the markings and a point, which is permanent relative to the machine part, are equal.

Abstract: The invention relates to a method for the maintenance of a plurality of processing stations (13) of a textile machine (10), whereby at least one first maintenance unit (14a-d) can travel alongside the processing stations (13) in order to service and/or control the processing stations (13). The maintenance unit (14a-d) may be moved into an optimized readiness position when none of the processing stations (13) needs to be serviced and/or controlled by the maintenance unit. Alternatively, the direction of travel in which the maintenance unit (14a-d) is to travel to the next processing station (13) in need of service is determined, whereby the direction of travel depends on the totality of processing stations in need of maintenance.

Abstract: For the piecing of a yarn in an spinning device, various computation formulas are stored in a control device into which calculated values as well as special data converted into numerical values relating in particular to the fiber material, the yarn and the spinning element are first entered to compute and select settings for operations relevant to the piecing process. A feeding device feeding a fiber sliver to the spinning device is first brought to a high pre-feeding speed by means of such pre-programmed values and converted data. From this pre-feeding speed, the feeding speed is greatly decelerated in steps to its piecing feeding speed in coordination with the release of the yarn to be fed back into the spinning element.

Abstract: A procedure and apparatus for start-up spinning of a thread in an open-end spinning apparatus is provided. A first and second auxiliary roll-pair are presentable within a thread course during start up spinning. A source of a suction air stream within the spinning apparatus is positioned below the first and second roll-pairs. The source of suction air stream creates a suction flow of air to induce the thread end into the spinning apparatus for start up spinning. A control center is in communication with the first and second roll-pairs, so that the control center controls them. A thread storage unit is positioned between the first and second roll-pairs proximal to the course of the thread. The thread storage unit is in communication with the control center so that the thread storage unit is activated to store and release the thread during start up spinning.

The method includes fixing the graduation support on an inner annular wall of the support body and positioning the support body so that the support body only partly covers the graduation support in an axial direction.

Abstract: Proposed is a procedure for the control of a service module for the maintenance of spinning stations and also a service module for the carrying out of this said maintenance. The procedure is carried out on a spinning machine, which can run at least one activity (A) at individual spinning stations, whereby this activity (A) consists, respectively, of at least one task (I-IV). In a case of a disturbance (4) in the course of the working of a task (I-IV), then the service module is immediately disconnected from automatic operation and is set in stillstand and subsequently, by the said service module itself, at least one procedure (a, b, c, d) for the correction of the said disturbance is carried out in order to complete the activity (A) which is to be carried out, or the service module is reset, into a fully operable state.

Abstract: Upon the start of spinning a thread (F), two auxiliary roll-pairs (20, 21) bring an end (E) of the concerned thread into a preparatory position (P) within an entrainment zone of a suction induced air stream, which stream enters an open-end spinning apparatus (10). At this point, in order to uphold the continuity of the thread, the said auxiliary roll-pairs (20, 21) are stilled in their revolution. With renewed drive, the second roll-pair (21), located more distant from the open-end spinning apparatus (10), causes a reversely directed thread movement, whereby, between the two said roll-pairs (20, 21), a thread surplus is created. This thread accumulation between the roll-pairs 20, 21 is retained in a pneumatic thread storage unit (23). The second auxiliary roll-pair (21) is then stopped from further rotation. The first auxiliary roll-pair (20), proximal to the open-end spinning apparatus (10), now opens itself, thus freeing its clamp on the thread.
