A double support roller winding machine for winding material webs onto core tubes with different diameters includes an attaching and severing device mounted so that it can be swung from above down into the roller bed where a new core tube has been inserted to engage the new core tube at its apex, to attach the web to the new core tube and to sever the fully wound roll which has been ejected from the roller bed from the attached web start.
