Abstract:
A method of making and processing a high bulk 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 of 9.0 grams per cubic centimeter 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 an unwind stand having torque transmitting clamping means for engaging opposite end surfaces of the parent rolls; engaging the clamping means on a first parent roll; partially unwinding the first parent roll using variable speed drive means operably associated with the clamping means; rotatably supporting the partially unwound first parent roll on a core placement table adapted to receive the partially unwound first parent roll from the clamping means; engaging torque transmitting clamping means on 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; and rewinding the joined web.
