(54) Yarn winding machine


(57) A spinning machine (1) includes a winding device (12), a yarn clearer (11), a cutter (10), a slack eliminating device (8), a yarn splicing device (92), and a main control section (21). The slack eliminating device (8) includes a slack eliminating roller (30) and a yarn detecting sensor (34) for detecting a yarn on the surface of the slack eliminating roller (30). If a yarn defect is detected by the yarn clearer (11) and a yarn is cut by the cutter (10), the main control section (21) determines whether or not to control the yarn splicing device (92) to carry out yarn splicing in accordance with a detection result of the yarn detecting sensor (34).
