Abstract (en)
[origin: EP3771674A1] A package exchanging device (7) includes: a splicer (66) which forms a continuous yarn (Y0) by entangling a yarn end (Y1) and a yarn end (Y2); first hooks (67a) and (68a) which are provided so that a movable amount from an initial state increases in response to a tension acting on the continuous yarn (Y0) when the tension becomes larger than a predetermined value; a catching and guiding mechanism (61) which catches the continuous yarn (Y0) to be locked to the first hooks (67a) and (68a) and moves the caught portion to a predetermined inspection position (P61) so that a tension is generated in the continuous yarn (Y0); a potentiometer (164) which acquires the movable amount of the first hooks (67a) and (68a); and a determination unit (90b) which determines whether a yarn joining operation is successful on the basis of the movable amount acquired by the potentiometer (164) when the catching and guiding mechanism (61) is moved to the inspection position (P61).
