摘要： A bobbin-type winder for winding a synthetic yarn at a constant speed is disclosed. The winder includes a bobbin shaft having a bobbin mounted thereon and a bobbin shaft driving apparatus, operably connected to a first inverter, for rotating the bobbin shaft. The winder further includes a traverse device for traversing the yarn supplied to the bobbin, and a contacting roll arranged such that it is movable into contact with the circumferential face of a yarn package wound on the bobbin. The contacting roll is driven via a second inverter and a rotational speed detector is provided for detecting the rotational speed of the contacting roll. A controller is electrically connected with the bobbin shaft driving apparatus and the rotational speed detector for controlling the rotational speed of the bobbin shaft in accordance with the detector rotational speed of the contacting roll. The second inverter is isolated from the controller so that a torque applied from the outer surface of the yarn package to the contacting roll is minimized.
