Q
The apparatus of the invention comprises a
member adapted to be driven ata predetermined
rate from the spindle drive of the machine, and
means actuated by said member for stopping the
55 rotation of the spindle when the predetermined
amount of yarn has been wound on to the packé-
age carrier. The spindle drive may, for example,
drive through suitable reduction gear a notched
