Abstract (en)

A creel 13 for arranging a large number of yarn-feeding bobbins has a nipping member 38 for holding an end of yarn led out of a newly placed yarn-feeding bobbin 12, a disk tensioner 40 for holding an end of yarn which is led out of an old yarn-feeding bobbin and which remains on the creel 13 at a predetermined position on the downstream side of the nipping member 38, and a knotter 42 for automatically knotting the two held yarns at a position between the two holders. There are further provided tension-applying means 15 and 34 for bringing a tension-applying lever 18 into contact with the knotted yarns 16 between the two holders by driving to thereby apply a predetermined amount of tension to the knotted yarns 16. There are further provided a detection piece 24 and a proximity sensor 32 for detecting a state of tension applied to the yarns 16 by the tension-applying means 15 and 34. <IMAGE>
