Abstract
A yarn-delivery device serving as a yarn feeder for textile machines is proposed. To provide an optimum regulation of the yarn transport even for more than one yarn, the yarn-delivery device has a storage drum which is made in one piece with the rotor or armature of the drive motor and which has on its circumference a wire lattice formed by wires arranged in an X-shaped manner. To regulate the yarn tension from the consumer, there is a yarn-tension sensor, the mechanical deflection of which causes an electronic adjustment of the drive motor.
Claims19
A yarn-delivery device for textile machines, comprising:
- a bobbin for a yarn;
- a drive motor having a rotor, said motor drawing the yarn off from said bobbin;
- a storage drum connected to said rotor to form a single unit, said storage drum storing the yarn drawn off from said bobbin in a plurality of turns lying next to one another, said storage drum including a plurality of steel wires arranged in an X-shaped pattern and forming a wire lattice at a circumference of said storage drum so that the yarn can be fed to and removed from said storage drum;
- a yarn-tension sensor being mechanically deflected by the yarn running off said storage drum;
- and
- regulating means for electronically evaluating and converting the mechanical deflection of said yarn-tension sensor for regulating a drive of said drive motor.
