| (54) | Yarn winding apparatus and yarn withdrawal method |
| (57) A winder unit 10 includes a cradle 23, a contact roller 29, an upper-yarn suction
opening 35, a drive mechanism 60, and a unit controller 50. The cradle 23 holds a
package 30, and the contact roller 29 comes into contact with a surface of the package
30. The upper-yarn suction opening 35 performs a sucking and catching operation to
catch a yarn end 30a trailing from the package 30. The drive mechanism 60 moves the
cradle 23 such that the package 30 is held at a non-contact position Q1 where the
package 30 is separated from the contact roller 29 and at a contact position Q2 where
the package 30 comes into contact with the contact roller 29. The unit controller
50 controls the drive mechanism 60 and the upper-yarn suction opening 35 such that
the upper-yarn suction opening 35 performs the sucking and catching operation when
the package 30 is held at each of the non-contact position Q1 and the contact position
Q2.
