Abstract

Interfolded webs such as those of tissue paper are provided in a stack. The upper two webs of the stack are so folded and interfolded as to provide four plies or folds of an upper web to the hand of a user to permit grasping of the full folded thickness for withdrawal. A method and apparatus to effect the particular folding of the upper starter web and next lower web of the stack are illustrated.

Claims

1. A sheet material assembly comprising a stack of longitudinally folded sheet material webs including an uppermost starter web and a next lower web, said uppermost web having longitudinal quarter folds all in overlying relation providing a folded web having an opening toward a side edge of the stack, the quarter folds of an edge portion and of a central portion of the uppermost web lying in contact, the quarter fold of the said one edge and of the opposite web edge defining said opening, and the said next lower web having an edge portion fold and an adjacent central portion fold in overlying relation and lying in said opening of the uppermost web interposed between and separated by an edge portion fold and a central portion fold of the uppermost web so that withdrawal of the uppermost web from the stack also partially withdraws the next lower web, said uppermost web being closed along a zone intermediate the side edges of the stack to permit grasping of the folded thickness of the uppermost web.
