A device for unwinding a tissue roll is disclosed, along with a method for processing high bulk tissue webs. The method includes forming a wet web, drying the web, winding the dried web to form a plurality of parent rolls, unwinding the parent rolls by transmitting torque through the roll center and/or ends, moving the partially unwound roll to effect splicing with a subsequent parent roll, and rewinding the thus united web. In particular embodiments, the torque transmitting means comprise side clamping mechanisms that engage only the end surfaces of the parent rolls. In other embodiments, an automated off-line method for splicing tissue webs from different parent rolls utilizes a finishing unit that substantially continuously impacts each web during unwinding the splice the webs together.
