rotating a winding drum about a center axis of the winding drum and directing a web material around the winding drum;
positioning a continuous loop in a spaced apart relationship relative to the winding drum to form a nip between a surface of the continuous loop facing the winding drum and the winding drum;
inserting a core and directing the web material through the nip between the surface of the continuous loop facing the winding drum and the winding drum;
positioning a rider roll relative to the continuous loop and the winding drum to define a winding space with the winding drum and the continuous loop; and
operating the continuous loop, the winding drum and the rider roll in a manner to wind the web material about the core in the winding space and form a log of wound web material.
