YARN WINDING DEVICE AND YARN CATCHING METHOD

YARN WINDING DEVICE AND YARN CATCHING METHOD

When a yarn (12) that is being wound by a winding section (2) is disconnected, an upper-yarn catching pipe (5) of an automatic winder (100) sucks and catches the yarn (12) from a package (20). A unit controller (50) controls a package driving motor. After the upper-yarn catching pipe (5) starts to s...

Zusammenfassung:When a yarn (12) that is being wound by a winding section (2) is disconnected, an upper-yarn catching pipe (5) of an automatic winder (100) sucks and catches the yarn (12) from a package (20). A unit controller (50) controls a package driving motor. After the upper-yarn catching pipe (5) starts to suck an upper yarn, the unit controller (50) causes a driving section to perform a forward-backward reciprocal driving that starts from a forward driving in which the package (20) is rotated forward in a winding direction of the yarn (12) and a backward driving in which the package (20) is rotated in a direction opposite to the winding direction for a rotation amount that is larger than the rotation amount in the forward driving.
