THREAD WINDER

WIPO Patent Application WO/2021/153479

A1

According to the present invention, the time and effort required to intentionally form a thread seam is reduced. An automatic winder 1 is provided with: a thread feeding part 11; a winding part 13; a cutter 33a which divides a running thread Y between the thread feeding part 11 and the winding part 13; a thread splicing mechanism 32 which, in a state where the thread Y is divided between the thread feeding part 11 and the winding part 13 in a thread running direction, performs a seam forming operation for splicing the thread Y supplied from the thread feeding part 11 to the thread end on the winding part 13 side to form a seam; and a unit control part 15. The unit control part 15 controls the winding part 13 and the cutter 33a so that the cutter 33a cuts the yarn Y each time the winding part 13 winds the thread Y of a predetermined length in a winding mode for winding the thread Y, and is able to execute a test package creation mode in which the thread splicing mechanism 32 is made to perform a thread splicing operation.
