According to the abstract released by the Intellectual Property India: "An object of the present invention is to improve the reduction effect of power consumption by effectively suppressing air resistance applied to an end face of a package at a time of yarn winding. A yarn winder 4 includes: bobbin holders 24 to which bobbins B, onto which yarns Y are respectively wound, are attached; a contact roller 25 configured to make contact with outer circumferential surfaces of packages P which are formed by winding the yarns Y onto the respective bobbins B; and endface gap covers 40 provided at the respective spaces 70 formed between end faces of the packages P that are adjacent in a front-rear direction. Each end-face gap cover 40 includes a contact roller surface 41 which faces the contact roller 25 side when viewed in the front-rear direction. The contact roller surface 41 is provided on the center Q side of a package P as compared to the outer circumferential surface of the package P in a radial direction of the package P. When viewed in the front-rear direction, at least part of the contact roller surface 41 is provided within an angular range of 30 degrees on the upstream side from the virtual line segment V connecting a contact C to a center Q of the package P and an angular range of 30 degrees on the downstream side from the virtual line segment V in a rotational direction of the package P."
