Abstract (en)
An apparatus comprising at least one stack of feeders (F1, F2, F3), each of which is provided with a motorized yarn winding reel (12) adapted to draw the yarn from a spool in order to feed it to a textile machine. The feeders (F1, F2, F3) are all connected electronically on a primary communication channel (32) in order to communicate bidirectionally with a central control unit (CU), are provided with electronic interconnection means (RXF, TXF) adapted to provide a secondary communication channel (34) which locally interconnects the feeders (F1, F2, F3) of the stack to one another, and are each programmed to communicate their own identification code (ID1, ID2, ID3) to the following yarn feeder in the stack by means of the secondary communication channel (34).
