    摘要： A partially unwound roll is moved for splicing with a subsequent parent roll, and the united web is rewound. The torque transmitting means include side clamping mechanisms engaging only the end surfaces of the parent rolls. In one aspect, an automated off-line apparatus and method splice tissue webs from different parent rolls in a finishing unit, and substantially continuous impacts on each web during unwinding splice the webs together. In one aspect, an apparatus and method are disclosed for the production of a soft, high bulk uncreped throughdried tissue web by depositing an aqueous suspension of papermaking fibers onto an endless forming fabric to form a web and through drying the web to final dryness without any significant differential compression to form a dried web having a bulk value of about 15 to 25 cubic centimeters per gram or greater, an MD Stiffness Factor of 50 to 100 kilograms, a machine direction stretch of 15 to 25 percent, and a substantially uniform density. A torque transfer device for unwinding a tissue roll includes a frame having a pair of arms spaced apart to accommodate the width of the roll, each arm having a side clamping mechanism mounted thereon to engage one of the opposite end surfaces of the tissue roll. The side clamping mechanism includes a backing plate connected to and rotatable with an unwind shaft connected to an electric drive, an inflatable bladder mounted on the backing plate, and means for inflating the bladder such that the opposite end surfaces of the roll are sandwiched between the side clamping mechanisms.

    摘要： A high bulk tissue web is made by depositing an aqueous suspension of papermaking fibers onto a forming fabric to form a web, drying the web, winding the dried web to form a plurality of large diameter parent rolls wound on a core, and transporting the parent rolls to an unwind stand having torque transmitting clamping means for engaging opposite end surfaces of the parent rolls. A backing plate is connected to and rotatable with an unwind shaft connected to an electric drive. An inflatable bladder is mounted on the backing plate. The clamping means engage a first parent roll by inflating the bladder such that the opposite end surfaces of the roll are sandwiched between the side clamping mechanisms for partially unwinding the first parent roll using a variable speed drive operably associated with the clamping means. The torque transmitting clamping means engage a second parent roll, and a leading end portion of the web on the second parent roll is joined to a trailing end portion of the partially unwound first parent roll to form a joined web without glue. In one aspect, the leading end portion of the web on the second parent roll is transported with a thread-up conveyor. In one aspect, the leading end portion of the web on the second parent roll is transported with vacuum means operably associated with an endless screen belt means with decreasing amounts of vacuum as the web is transported over the endless screen belt means.
