Cross Winding Package, Method For Producing Cross Winding Package, And Yarn Winding Apparatus

Abstract: A cross winding package (100) of a cross winding package includes a cone-shaped winding bobbin (120) and a yarn layer (110). The winding bobbin (120) has a taper-shaped winding surface inclined from a central axis (C) by a first angle (θ). The yarn layer (110) is 5 wound up around the winding bobbin (120) having a surface of the wound yarn with the same inclination as the winding surface of the winding bobbin (120). The yarn layer (110) includes a first yarn layer (111) that contacts the winding bobbin (120) and has a first traverse width (W1), a second yarn layer (112) that is on the first yarn layer (111) and has a second traverse width (W2) that decreases partially or entirely along with increase in distance from the first 10 yarn layer (111), and a third yarn layer (113) that is on the second yarn layer (112) and has a third traverse width (W3). The first traverse width (W1) and the third traverse width (W3) satisfy the relationship of W1×1/2 ≤ W3 ≤ W1×2/3. This cross winding package has a low unraveling tension.
