Abstract (en)

[origin: EP3865441A1] A yarn is properly guided to a yarn holding portion by a clamp cutter, when a completed package is replaced with a new bobbin. A clamp cutter 50 performs at least first movement and second movement. The clamp cutter 50 performs the first movement after cutting and holding a part of a yarn Y between a yarn supplying unit 11 and a package P. The first movement includes a rearward movement component and is movement in a direction in which the yarn is pulled out from the yarn supplying unit 11. The clamp cutter 50 performs the second movement after the first movement, in order to guide the held yarn Y to a yarn holding portion 28 of a bobbin holder 22. The second movement includes a forward movement component. After the clamp cutter 50 starts the second movement and until the yarn Y is held by the yarn holding portion, a controller 14 causes a feed roller 16 to rotate backward to remove the slack of the yarn Y.
