| 20110295401 | Programmable Sensor Suitable for Controlling Yarn Feed to a Textile Machine and Method for the Programming Thereof - Sensor for controlling thread or yarn feed to a textile machine wherein a body or casing suitable for being arranged on a support of the machine or positioned near to it and having detection methods suitable for detecting at least one feed characteristic of the yarn to the machine. In the casing or body of the sensor, resources are provided for control of the detection and suitable for modifying the modes of control according to a plurality of control algorithms stored in memory associated with the casing; associated with the latter, selector methods are also provided suitable for allowing a user to choose one of the algorithms, thus selecting the desired operating mode of the sensor during its yarn feed control. The method for selecting desired sensor operating mode is also disclosed. | 12-01-2011 |
| 20110006096 | DEVICE AND METHOD FOR THE CONSTANT TENSION FEEDING OF THREADS OR YARNS FED IN A DISCONTINUOUS WAY - Device and method for constant tension feeding, threads or yarns fed to textile or winding machine or metallic wire to similar machine, in discontinuously with phase sequences. The thread motion has at least first and second feeding or absorption states following each other in time. A controller, connected to a tension detector and thread accumulator, intervenes on the accumulator based upon tension value from the detector. A compensator, between the accumulator and tension detector, cooperates with thread to compensate variation of feeding or absorption state of the thread upon passage between each first and second feeding or absorption state. The controller intervenes to modify the accumulator's action on thread and maintain tension value detected by the detector at set value. Interaction between thread and compensator keeping constant tension value during the changing phase of the feeding state. The compensator freely moveable under action of thread relative to a resting position. | 01-13-2011 |
