A device for feeding warp yarns to a loom, comprising a support member (2); a cylinder (3) associated with said support member (2) and rotatable about its rotation axis (R), and on which a plurality of warp yarns can be wound; at least one motor (4) associated with said cylinder (3) to subject it to rotation; at least one tension sensor (5) active on at least one yarn to generate a tension signal (ST) representative of the value of the tension acting on said yarn; a control unit (6) connected to said tension sensor (5) to receive said tension signal (ST) and to generate and send to said motor (4) a command signal (SC) representative of the velocity of the motor (4), to maintain the value of said tension constant. |
