Abstract
A yarn winding device which comprises a yarn feeding unit for feeding a yarn at a predetermined yarn speed, an absorbing unit for absorbing a variation of a yarn speed by storing the yarn therein, a tensioning unit for applying a predetermined tension to a yarn, and a yarn winding unit for winding a yarn on a bobbin while traversing the yarn. A yarn detecting unit is provided for detecting whether or not a yarn is in front thereof in the absorbing unit and a control unit is also provided for controlling yarn winding speed of the yarn winding unit by increasing and decreasing that speed in accordance witha signal from the yarn detecting unit indicating a yarn existence or non-existence. After all, this yarn winding device makes a cone cheese package or a ribbonless package under constant tension by using an absorbing means between a feeding unit and a winding package.
