| 20130056573 | Improved Method and Device for Feeding a Yarn or Thread to a Processing Machine with Constant Tension and Velocity - A method for feeding a yarn or thread to a processing machine, such as a textile machine, the method includes unwinding the yarn from a bobbin, bringing it into cooperation with a rotary member and then directing it to a sensor member arranged to verify its feed tension to the processing machine, with monitoring of the yarn feed velocity. The measured tension and measured velocity data being fed to a control unit which controls the yarn feed to the machine. The tension is continuously controlled by the unit to maintain it constant then, if this tension condition is verified, the velocity is controlled to render it constant, while at the same time the tension value is continuously monitored to verify whether it remains constant.
