Abstract (en)
An object of the present invention is to provide a winding device which is able to suppress the variation of contact pressure while using the weight of a package as the contact pressure.When viewed in an axial direction of a rotation drum 40, each cradle arm 30 swings so that, as the diameter of a package Pw increases, a direction of an inclined straight line L connecting a swing fulcrum U with a center V of a bobbin Bw supported by the cradle arm 30 gradually approaches a vertical direction. Furthermore, until the direction of the inclined straight line L becomes identical to the vertical direction after the start of winding of a yarn, a contact point S between the rotation drum 40 and the bobbin Bw or wound package Pw is arranged to be within an angle which is more than 0 degrees and less than 45 degrees on the premise that a horizontal direction passing through a starting point which is a center C of the rotation drum 40 is defined as 0 degrees.
