Abstract: A roll changer for delivering a web of material has, for edge-aligned connection of the trailing end of a delivered web with the leading end of the web from a new roll, in addition to the web edge-sensor controlling the position of the delivery roll during such delivery, a roll sensor responsive to the position of the edge of the outermost turn of the new roll, adjusting the axial position of the new roll. The sensors are switched to the respective controllers upon rotation of the roll turret to deliver a new roll to the waiting position.
