Uniformly wound rolls of soft tissue sheets having high bulk

摘要: A uniformly wound parent roll of soft, high bulk tissue has greater uniformity in sheet basis weight, machine direction stretch and when compared to rolls by conventional winding methods. The method involves carrying the on a relatively air impermeable transfer belt (18) which traverses an unsupported span between two drums. (15) is transferred from (25) as urged against sheet/transfer at point within span. resulting deflection detected and, response, reel spool position controllably changed maintain predetermined limits. tension controlled differential speed outer most surface belt.
