  • Patent number: 5310126
    Abstract: A winding machine has winding stations and a transport path for leading cops to the winding stations. An apparatus for loosening a reserve yarn winding from peripheries of the cops disposed at the transport path includes scissors having two legs being open at an onset of a yarn search. One of the legs is a yarn loosener to be placed against a cop positioned on the transport path. The cop is rotated to bring the yarn loosener under the reserve yarn winding. An actuator closes the scissors after a predetermined search period. The apparatus for loosening the reserve yarn winding may include a yarn loosener to be placed at a cop positioned on the transport path, wherein the yarn loosener has a forward edge for picking up a yarn, and a sharp cutting edge with a height being increased at increasing distances from the forward edge for cutting the yarn.

  • Patent number: 5301887
    Abstract: A heat sensor which detects the heat generated from sliding frictional contact with a traveling yarn in a textile machine and generates control signals therefrom for the controlling of a yarn winding operation. A temperature-sensitive electric resistor, especially a thin-layer resistor or a film thermometer, serves as the heat sensor. The heat sensor is connected e.g. via a signal converter to control devices, e.g. to a controllable yarn brake and/or to a drive motor for yarn take-up. When the measured temperature rises above a limit value, the braking force of the yarn brake can be first lowered and then the speed of the drive motor can be reduced.

  • Patent number: 5301886
    Abstract: The present invention provides a method and apparatus for operating a textile winding machine to wind yarn packages with the capability to verify a reported yarn break situation and to respond accordingly in the event that a yarn break has not, in fact, occurred. A sensing device at a textile winding station senses the travel of a yarn therepast as the yarn is wound from a supply package onto a take-up package. In the event of a yarn break or movement of the yarn beyond the sensing range of the sensing device, the sensor reports the absence of yarn to a control unit. The control unit responds to the signal from the sensing device by stopping the yarn winding operation and implementing a yarn re-establishment operation.

  • Patent number: 5279474
    Abstract: Method and apparatus for making a filament winding amenable to inside payout and having squared-off ends providing optimal volumetric efficiency. The filament crossovers are distributed so as to reduce crossover stacking in one or a few places which can interfere with winding and payout from the finished winding. A base wire layer is wrapped onto a mandrel over which a guide is nestingly wound with adjacent guide wire turns spaced apart. The filament first layer is wound nesting in the guide wire spaces, and subsequent filament layers accordingly formed. Each crossing filament turn has an advance in a crossing region substantially aligned with a crossover region in the underlying layer and which in one embodiment is one-half the winding pitch.
