<p>A novel apparatus and method for processing high bulk tissue webs are disclosed for 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 of 9.0 grams per cubic centimeters or greater, 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 (160) for engaging opposite end surfaces of the parent rolls. A backing plate (168) is operably connected to and rotatable with an unwind shaft (162) connected to an electric drive. An inflatable bladder (164) is mounted on the backing plate. The clamping means engage a first parent roll (R) 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.</p> |
