A yarn winder, used for winding various kinds of yarns by automatically setting the moving speed of a bobbin holder so that it is suitable for the increasing size of the yarn package wound onto the winding bobbin holder. In the winder, while a contact roller (7) is pressed onto a bobbin (9) inserted onto a bobbin holder (8) or a yarn layer wound on the bobbin (9), a yarn (Y) is traversed by a traverse apparatus (6), and thus, the yarn is wound on the bobbin. The movement of the contact roller due to increase of the wound yarn is detected by a sensor (16), and the slider is moved based on signals detected by the sensor so as to move the bobbin holder in such a direction that it moves away from the contact roller. The slider is actuated by signals from the sensor detecting the amount of the movement of the contact roller, and the speed of the winder can be varied stepwise or continuously.
