ABSTRACT:
A device for monitoring the feed of a plurality of yarns (2) to a textile machine (1) comprises a number of sensor means (4) equal to the number of yarns (2) and each cooperating with a corresponding yarn (2) of which they sense the state of feed, and being connected to a control unit (5) which, on the basis of the signals generated by the sensors and of a reference signal (V.sub.A) which is a function of the operating position of the machine (1), enables this latter to be activated or not. The sensors (4) are connected to the unit via a number of connection members less than the number of sensors, each sensor being provided with its own identification code. The device is controlled by the control unit (5) which sequentially interrogates the various sensors (4) by feeding them their own identification code, only that sensor (4) which recognizes this code then feeding to the unit the data relative to the state of the yarn (2) monitored by it.
