A yarn winding device comprising: a yarn supplying section adapted to supply a yarn; a yarn storage device adapted to pull out the yarn from the yarn supplying section and temporarily store the yarn; a package forming section adapted to pull out the yarn from the yarn storage device and wind the yarn around a winding bobbin to form a package; and a control section adapted to control the package forming section, wherein the package forming section includes a package supporting section (44, 45) adapted to rotatably support the package, a package rotation detecting section adapted to detect a rotation amount of the package, a contact roller adapted to rotate while making contact with the package supported by the package supporting section (44, 45) to rotate the package, and a roller drive source adapted to rotatably drive the contact roller, characterized in that the control section carries out a deceleration control of decelerating the contact roller while adjusting such that a difference in peripheral speeds of the package and the contact roller is smaller than or equal to a predetermined value in a state where the yarn is connected between the yarn storage device and the package forming section and in a state where the package and the contact roller are brought into contact with each other based on a detection result of the package rotation detecting section and a rotation speed of the contact roller, wherein the control section calculates a reference value of a difference in peripheral speeds of the package and the contact roller based on the rotation speed of the contact roller and the detection result of the package rotation detecting section in a predetermined period before start of the deceleration control, and carries out the deceleration control using the reference value. a yarn supplying section adapted to supply a yarn; a yarn storage device adapted to pull out the yarn from the yarn supplying section and temporarily store the yarn; a package forming section adapted to pull out the yarn from the yarn storage device and wind the yarn around a winding bobbin to form a package; and a control section adapted to control the package forming section, wherein the package forming section includes a package supporting section (44, 45) adapted to rotatably support the package, a package rotation detecting section adapted to detect a rotation amount of the package, a contact roller adapted to rotate while making contact with the package supported by the package supporting section (44, 45) to rotate the package, and a roller drive source adapted to rotatably drive the contact roller, characterized in that a package supporting section (44, 45) adapted to rotatably support the package, a package rotation detecting section adapted to detect a rotation amount of the package, a contact roller adapted to rotate while making contact with the package supported by the package supporting section (44, 45) to rotate the package, and a roller drive source adapted to rotatably drive the contact roller, characterized in that the control section carries out a deceleration control of decelerating the contact roller while adjusting such that a difference in peripheral speeds of the package and the contact roller is smaller than or equal to a predetermined value in a state where the yarn is connected between the yarn storage device and the package forming section and in a state where the package and the contact roller are brought into contact with each other based on a detection result of the package rotation detecting section and a rotation speed of the contact roller, wherein the control section calculates a reference value of a difference in peripheral speeds of the package and the contact roller based on the rotation speed of the contact roller and the detection result of the package rotation detecting section in a predetermined period before start of the deceleration control, and carries out the deceleration control using the reference value.
