ABSTRACT:
An apparatus and method for winding tissue webs into a parent roll includes a rotatable reel drum having a flexible outer shell for engaging a web of tissue paper against a reel spool. A deflection sensor is mounted adjacent to the inner surface of the outer shell for measuring the amount of deflection of the flexible outer shell caused by the paper roll. The amount of deflection is related to the pressure at the nip point and, by moving the reel spool and flexible reel drum away from each other as the diameter of the paper roll increases, the pressure can be controlled at a desired level. Accordingly, a predetermined light nip pressure can be applied to the roll as the tissue web is wound thereon and large parent rolls of high bulk tissue can be manufactured with desired properties when unwound.
