Method and device for discontinuing operation of a winding device after a thread break occurs

In a device for carrying out a method of discontinuing operation of a winding device for textile coils after a thread break, the winding device having a winding cylinder for frictionally driving a coil to be wound, means for disconnecting the operation of the winding device, means operatively connected to the coil for actuating said disconnecting means in response to a predetermined coil winding fullness and means activated by said disconnecting means for stopping the driving of the winding cylinder and for issuing a demand signal for a coil exchange, means for issuing a thread break signal upon the occurrence of a break in a thread being wound on the coil, means associated with said actuating means and responsive to the thread break signal for rendering the disconnecting means ineffective and for inducing subsequent lifting of the coil away from the winding cylinder and including means responsive to the thread break signal for stopping the driving of the winding cylinder and the rotation of the coil and for inducing issuance of at least one signal selected from the group of signals consisting of a fault signal and a demand signal for automatically activating a fault-eliminating device.

In a device for carrying out a method of discontinuing operation of a winding device for textile coils after a thread break, the winding device having a winding cylinder for frictionally driving a coil to be wound, means for disconnecting the operation of the winding device, means operatively connected to the coil for actuating said disconnecting means in response to a predetermined coil winding fullness and means activated by said disconnecting means for stopping the driving of the winding cylinder, means for issuing a thread break signal upon the occurrence of a break in a thread being wound on the coil, means associated with said actuating means and responsive to the thread break signal for rendering the disconnecting means ineffective and for inducing subsequent lifting of the coil away from the winding cylinder, the winding device having a winding mandrel for the coil being wound, drive means for the winding cylinder, and a clutch for engaging the drive means to drive the winding cylinder, and including switching means, means for braking the winding mandrel, and means for braking the winding cylinder, said switching means being responsive to the thread break signal for engaging said means for braking said winding mandrel and said winding cylinder.

In a device for carrying out a method of discontinuing operation of a winding device for textile coils after a thread break, the winding device having a winding cylinder for frictionally driving a coil to be wound, means for disconnecting the operation of the winding device, means operatively connected to the coil for actuating said disconnecting means in response to a predetermined coil winding fullness and means activated by said disconnecting means for stopping the driving of the winding cylinder, comprising means for issuing a thread break signal upon the occurrence of a break in a thread being wound on the coil, means associated with said actuating means and responsive to the thread break signal for rendering the disconnecting means ineffective and for inducing subsequent lifting of the coil away from the winding cylinder.
