The invention relates to a vibration-damping apparatus (18) for a winding device (4) of a textile machine (1), which textile machine produces cross-wound packages (5), the vibration-damping apparatus being provided for reducing the vibrations that occur at the pivotably mounted package cradle (8) during the winding operation of the textile machine (1).

According to the invention, in order to obtain a vibration-damping apparatus which is unproblematic both with regard to safety and with regard to contamination and which also always ensures a vibrationally relatively stable state of the package cradle, the vibration damper is in the form of a friction damper (20) having friction forces of different intensity depending on the working direction, the friction forces acting as the cross-wound package (5) lifts off during the winding operation being greater than the friction forces acting during the return of the cross-wound package (5).

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.

A winding device and associated method for swiveling a bobbin in the winding device during an interruption of a winding operation are provided, wherein the bobbin rests on a backing roller and is formed on a bobbin tube onto which a thread is wound. The bobbin tube is rotatably held between holders on two retaining arms mounted on a common swivel arm having a swivel axis. With force measurement unit, one of intrinsic weight of the bobbin or a force effect that acts on the retaining arms due to contact of the bobbin with the backing roller is measured. A manual force is transmitted into at least one of the retaining arms in a force direction that is determined by evaluating the force measurement unit. With a drive that is operably configured with the swivel arm, the swivel arm is swiveled in the force direction.

A winding device for winding a yarn onto a package tube has a spindle that holds and rotationally drives the package tube. A support roller abuts against a peripheral surface of the yarn winding package during winding of the yarn. The spindle is supported by a pivotably mounted swivel arm so as to swivel relative to the support roller. A contact-force control device is provided and includes an actuator disposed to actuate the swivel arm, and a control device configured with the actuator. A bending beam load cell is configured on the swivel arm to determine an actual value of a contact force between the yarn package and the support roller. The contact force is regulated to a predetermined target value via control of the actuator by the control device.

The frame brake assembly includes a sleeve, a piston, a brake, and a retracting device. The piston translates within the sleeve between an upper first position and a lower second position. A brake is coupled to a lower portion of the piston beneath the sleeve. As the piston moves between positions, the brake moves in a corresponding manner. In the second position, the brake is lowered into contact with the ground. The retracting device is used to automatically return the piston and brake to the first position. When installed on the coiling machine, the frame brake assembly is coupled to the frame of the coiling machine and is in selective engagement with a pair of spool arms. Rotation of the spool arms induces translation from the first position to the second position in the frame brake assembly.
