Abstract (en)
[origin: EP2708625A1] A housing (12) supports a yarn-winding drum (22) which is driven to rotate by a motor (18) controlled by an electronic circuit (C) as a function of signals from a sensor tension (40) integral with the housing (12). The tension sensor (40) comprises a flexible member (42) arranged to interfere with the yarn unwinding from the yarn-winding drum (22) and to bend to a variable extent depending on the yarn tension. The flexible member (42) incorporates circuit means (R) that generate a variable output depending on the bent configuration of the flexible member. The housing (12) has a first peripheral surface (12a) and an opposed, second peripheral surface (12b) which have mutually engageable profiles and are provided with respective male/female connectors (52, 54) for mechanical/electrical connection of a plurality of identical feeders in a stacked configuration (80). The electronic circuit (C) is programmed to enable the motor (18) to unwind yarn in response to a deformation of the flexible member (42) with respect to a resting configuration corresponding to a predetermined, minimum tension, on the basis of setup instruction transferred via the connectors (52, 54).
