Abstract (en)
A creel (12) comprising a frame (16) which supports a battery of spools (14) arranged on multiple horizontal rows and a series of yarn guiding eyelets (18) arranged to guide and support the yarns along their path from the spools (14) to an output end (12c) of the creel (12). The yarns are fed to a warping machine (10) by respective yarn feeders (23), each of which comprises a yarn winding reel (24) which is individually motorized. The yarns in output from the spools (14) are diverted toward the output end (12c) by yarn guiding means. The yarn feeders (23) associated with a same row of spools (14) are all supported at the output end (12c) and are subjected to control means adapted to adjust the rotation rate of the yarn winding reels (24) as a function of the signals received from respective load cells (26) functionally arranged between the yarn winding reels (24) and the warping machine (10), so as to stabilize the tension of the respective yarns fed to the warping machine (10) at a fixed or variable preset level.
