A yarn winding apparatus (4) comprising a unit control portion (50) which controls the yarn winding device (4), a yarn feeding portion (18) supporting a yarn feeding bobbin (6), a bunch forming portion (60), a yarn unwound from the yarn feeding portion (18) (20) to form a bundle (30), and a yarn monitoring device (15) disposed between the yarn feeding portion (18) and the bundling portion (60) for monitoring a state of the advancing yarn (20). The unit control section (50) identifies, from a monitoring result obtained from the yarn monitoring device (15), a yarn feed bobbin (6) on which a yarn is wound with a deficiency of raw material due to the supply of a roving in a ring spinning machine (2).
