Abstract (en)

A yarn winding machine includes a winding device, an operating device, a supply device, a yarn threading device, and a control unit. The control unit is configured to perform a first control when a first-type error has been detected, the first control performed to control the operating device, the supply device, and the yarn threading device such that a first bobbin is discharged from a pair of bobbin holders, a second bobbin is supplied to the bobbin holders, and the yarn is threaded onto the second bobbin. The control unit is configured to perform a second control when a second-type error has been detected, the second control performed to control the operating device, the supply device, and the yarn threading device such that the yarn is threaded onto the first bobbin while the state in which the first bobbin has been supplied to the bobbin holders is being maintained.
