Title:

THREAD PICKUP DEVICE, THREAD TAKEUP DEVICE, AND THREAD SPLICING METHOD

Document Type and Number:

WIPO Patent Application WO/2015/029275

Kind Code:

A1

Abstract:

This thread pickup device (28) comprises an upper-thread capture/guidance device (30) and a detection unit (68). The upper-thread capture/guidance device (30) has a moving capture part (30a) that moves from a standby position towards a takeup part (17), to a capture position, and captures a takeup-part-side thread, i.e. a takeup thread, by applying suction thereto. The detection unit (68) detects the takeup thread captured by the upper-thread capture/guidance device (30). By moving from the standby position to the capture position, the moving capture part (30a) approaches the detection unit (68) (that is, the detection unit (68) is provided somewhere other than on the moving capture unit (30a)), and with the moving capture part (30a) having moved to the capture position, the detection unit (68) detects the presence or absence of the takeup thread inside the moving capture part (30a).
