Title:
AUTOMATIC WINDER
Document Type and Number:
Japanese Patent JP2009286608
Kind Code:
A
Abstract:

To improve the productivity of an automatic winder by preventing a doffing device from failing in capturing thread when performing doffing work in the automatic winder.

This automatic winder is provided with a bobbin set part 18, a cradle 23, a first relay pipe 25, an automatic doffing device 98 and a pair of discs 73 of a disc tensor 13. A winding bobbin mounted on the cradle 23 can wind thread 20 unwound from a thread feeding bobbin 21 set in the bobbin set part 18. When performing the doffing work, the first replay pipe 25 captures the thread 20 from the thread feeding bobbin 21, and pulls out the thread to the cradle 23 side. Before the thread 20 in this pulled out state is captured by a thread pull-out arm 61 (clamp cutting head 65) of the automatic doffing device 98, the pair of discs 73 rotate to impart tension to the thread 20.
