Disclosed is a system for winding an end of a thread on a central axis of a spool. The system includes a support means for the central axis, the support means being associated with a mechanism for driving this axis in axial rotation. The system further may have a mechanism for moving a portion of the thread to be wound, positioned downstream of the free end of the thread, and a hooking interface to catch a portion of the thread to be wound, this interface being positioned at the end of the spool central axis and fixed in rotation with the central axis to drive the winding of the thread around the central axis. Finally, the system may have a cutting mechanism of the thread upstream of the portion of the thread interacting with the hooking interface.

The invention relates to a method for operating a textile machine (1) with a multiple number of similar work stations (2), whereas, with the assistance of work stations (2) during normal operation, yarn is produced or is rewound from a delivery coil onto a receiving coil, and whereas normal operation at the individual work stations (2) is interrupted at certain time intervals and is resumed with the assistance of a maintenance operation, and whereas the maintenance operations are carried out by one or more maintenance devices (3). In accordance with the invention, it proposed that for each work station (2), one or more production-related parameters are known or are determined, and that if more maintenance operations are to be carried out simultaneously than can be carried out by the maintenance devices(s) (3), the selection of the work station (2) to be serviced next will then be made under consideration of such production-related parameters, in such a manner that an upcoming batch change is completed as early as possible.

The invention relates to a method for monitoring the quality of a yarn on a textile machine, wherein the yarn passes a monitoring unit of the textile machine, with the aid of which at least one measured variable (M) which is dependent on a physical parameter of the yarn is determined, and wherein the measured variable (M), or a variable derived therefrom, is evaluated with respect to the position thereof with regard to at least one reference value (R). According to the invention, it is proposed that the selection of the reference value(s) (R) takes place taking into account one or more characteristic variables of the yarn, said characteristic variables being yarn-specific and defined prior to evaluating the measured variable (M). Furthermore, a textile machine is proposed which comprises at least one monitoring unit for monitoring at least one physical parameter of the yarn, and at least one controller which is operatively connected to the monitoring unit. The textile machine is characterized in that the controller is configured to monitor the yarn quality according to one or more of the preceeding claims.

A yarn cone holder whereby the yarn cone is mounted on an angled wire section of the holder with a yarn retention arm disposed substantially below the yarn cone and extending outwardly therefrom and including a resilient pad with the lower edge of the yarn cone deforming the resilient pad.

This bobbin unwinding device (32A (32B)) is provided with a bobbin support shaft (33) which rotatably supports a bobbin (B) around which a band-like fiber bundle (F) is wound, a fixed guide (35) which changes the running direction of the fiber bundle (F) unwound from the bobbin (B), and an auxiliary roller (34) arranged between the bobbin (B) and the fixed guide (35), wherein the fixed guide (35) is arranged such that the shaft center of the fixed guide (35) is substantially perpendicular to the shaft center of the bobbin support shaft (33), and the auxiliary roller (34) is arranged such that the shaft center of the auxiliary roller (34) is parallel or substantially parallel to the shaft center of the bobbin support shaft (33).

With regard to a filament winding device in which a plurality of fiber bundles are simultaneously wound around a liner, a tension detecting portion and a tension adjusting portion are miniaturized, the cost of the tension detecting portion and the tension adjusting portion is reduced, and the tension detecting portion and the tension adjusting portion are easily arranged. Provided is a filament winding device 100 that includes a tension adjusting portion 110 that collectively adjusts tension of a plurality of fiber bundles F unreeled from a plurality of bobbins B and an unreeling failure detecting portion 130 that individually detects the unreeling failure of the fiber bundles F on the bobbins B for each bobbin B.

A textile machine producing take-up packages, comprising a storage area for wound take-up packages, a detecting element for measuring the weight of each take-up package to be placed on the tray, a summing element for adding up the measured weights of the take-up packages to be placed on the storage area, and an output element for outputting an output signal if the sum of the measured weights of the take-up packages exceeds a predefined threshold value.

This invention includes an annular hysteresis brake (34) having one end fixed to a stationary frame (11), a support shaft (6) extending through a hollow portion of the hysteresis brake (34), and a spindle part (4) rotatably supported by the support shaft (6). The hysteresis brake (34) includes a yoke (36), a cylindrical hysteresis member (46) inserted into an annular space (41) of the yoke (36), and a hub (37) for rotatably supporting the hysteresis member (46). The spindle part (4) is supported by the support shaft (6) such that the spindle part (4) is restricted from moving toward the hysteresis brake (34) by a sleeve (15). The spindle part (4) and hub (37) are coupled with each other so as to rotate together via pins (21). This invention can simplify the structure while preventing damage to the hysteresis brake, thereby reducing the manufacturing cost of a thread-supplying spindle unit.

A winding device for winding a thread onto a bobbin tube to form a bobbin includes a machine frame, a controller, and a support roller rotatably mounted in the machine frame to support the bobbin tube or the bobbin. A winding mandrel holds the bobbin tube and is pivotally held on a pivot lever that is rotatably mounted on a rotary axis in the machine frame. The pivot lever includes a first and a second lever arm, wherein the winding mandrel is provided on the first lever arm. A linear drive is provided on the second lever arm to move the pivot lever about the rotary axis, wherein the linear drive is connected to the second lever arm via a push rod and an axle bolt and is pivotally attached to the machine frame via a holder. A force measurement device is arranged between the axle bolt and the holder.
