Abstract:
A method of making a soft, high bulk uncreped throughdried tissue web, comprising:depositing an aqueous suspension of papermaking fibers onto an endless forming fabric to form a web;drying the web to form a dried web having a bulk value of about 9 cubic centimeters per gram or greater;winding the dried web to form a plurality of parent rolls each comprising a web wound on a core;transporting the parent rolls to a frame including a pair of horizontally spaced apart side frames, each side frame comprising an elongated arm mounted on and moveable relative to the side frame, each elongated arm comprising a retractable chuck means;inserting the retractable chuck means into a first parent roll core;moving the elongated arms to transport the first parent roll core to an unwind position;partially unwinding the first parent roll using variable speed drive means operably associated with the chuck means; moving the elongated arms and the partially unwound first parent roll toward a core placement table, the core placement table adapted to receive from the elongated arms the partially unwound first parent roll;rotatably supporting the partially unwound first parent roll on the core placement table;moving the elongated arms away from the core placement table;inserting the retractable chuck means into a second parent roll;joining a leading end portion of the web on the second parent roll to a trailing end portion of the partially unwound first parent roll by embossing to form a joined web without glue;breaking the trailing end portion of the first parent roll by operating brake means associated with the core placement table to stop the expiring parent roll from turning, thereby breaking the expired web; andrewinding the joined web.
