Abstract (en)
A motorized positive yarn feeder with selectable operating mode is provided with a motorized reel (12) having a yarn (Y) wound thereon, which picks up the yarn from a spool (S) and feeds it to a textile machine (TM); a control unit (CU) can operate selectively in a position control mode, in which it receives a position signal (θTM) from the textile machine (TM), and, on the basis of a position signal of the reel (12), it controls the position of the reel (12) in a closed loop according to a transmission ratio that can be set electronically with respect to the position of the textile machine (TM), or in a tension control mode, in which it controls the speed of the reel (12) in a closed loop on the basis of a tension signal of the yarn, so as to stabilize the tension of the yarn (Y) at a reference tension value or at a tension profile that can be set by a user.
