Abstract (en)

[origin: EP3640174A1] To improve unwindability and suppress the latching in the package. The package 7 includes a winding tube 6 having no initial level difference and having both ends flangeless, and a yarn 4 wound around it. The yarn 4 includes a first step 7A and a second step 7B arranged with each other in a longitudinal direction of the winding tube 6. The second step 7B has a diameter larger than that of the first step 7A. The yarn 4 includes a first yarn layer 51 and a second yarn layer 53 alternately layered with each other. The first yarn layer 51 is wound with a width (A) from a reference end (P) corresponding to the first step 7A and the second step 7B. The second step 7B is wound with a width (B) narrower than the width (A) only corresponding to the second step 7B.
