Abstract
To shape paperboard sheets into cylindrical winding cores in a winder instead of using ready-made hollow core tubes thereby doing away with the necessity of waste disposal of used winding cores or facilitating the discarding disposal by restoring them to the original flat shape. In the winding of a web using a multi-spindle turret type of winder, the spindle positions of the turret are allotted to a winding core shaping station, a web winding-up station and a wind-roll removal station. At the winding core shaping station, each sheet of paperboard is rolled and lapped around a winding core shaft and butt joining parts are attached with a pressure-sensitive adhesive tape to shape each winding core, shaped winding cores are transferred to the web winding-up station by the turning movement of the turret to conduct the winding, each full wind-up roll is transferred with further turning movement to the removal station and removed from the winder.
