A slitter-winder for winding of pulp webs or corresponding webs with a thickness of at least 0.5 mm, in which the winder is a two-drum winder having two winding drums on support of which at least two pulp web rolls are wound. At least one of the winding drums is a nip acceptance winding drum (NAWD), that is a winding drum with a cover having a hardness of 40-80 Shore A and a thickness of 3-50 mm. The winding drums and a steel core or a shaft of the at least two pulp web rolls have parallel rotation axes and are in a rolling contact where the at least one winding drum is driven.

A thin metal strip winding method includes: a step of causing a thin metal strip to fly from a flight tube; a cutting and grasping step of cutting and grasping any portion of the thin metal strip flying from the flight tube; a thin metal strip connecting step of connecting the any portion of the thin metal strip cut and grasped in the cutting and grasping step and a leader as a ribbon, the leader being a to-be-connected portion of another thin metal strip remaining on a winding roll set on a winding roll rotation unit of a winder that winds up the thin metal strip; and a thin metal strip winding step of winding up the ribbon around the winding roll by causing the winding roll rotation unit to rotate.
