1. A tissue or towel stack comprising:
- a plurality of discrete tissue or towel leaves, each leaf folded so as to provide at least three tissue or towel panels, the leaves being folded back upon themselves so that each leaf has a first set of panels which consists of an end panel and at least the next adjacent panel, which first set of panels is overlappingly located between a second set of panels that consists of an end panel and at least the next adjacent panel of an adjacent folded leaf, and wherein the leaves are substantially identical, and the panels of each leaf are substantially the same size and configuration.

4. A method of producing a towel or tissue rack comprising the steps of:
-
providing a continuous web of towel or tissue material; delivering the web to a cut off roll to transversely cut the web to form discrete towel or tissue leaves; delivering the leaves from said cut off roll to a lap roll; delivering the leaves from the lap roll to a retard roll so that each leaf has a leading portion overlapping a trailing portion of the preceding leaf, the leaves overlapping by a predetermined length; delivering the leaves from the retard roll to a folding roll; transversely folding each leaf at the fold roll to have at least three leaf panels, with overlapping portions of adjacent leaves being folded to form discrete panels such that each leaf has a first set of panels which consists of an end panel and at least the next adjacent panel folded between a second set of panels that consists of an end panel and at least the next adjacent panel of an adjacent folded leaf, and wherein the leaves are substantially identical, and the panels of each leaf are substantially the same size and configuration. - View Dependent Claims (5, 6, 7)

8. A machine to produce a towel or tissue stack, each stack having a plurality of leaves, with each leaf consisting of at least three panels, said machine comprising:
-
a cut off roll which receives a continuous web of towel or tissue material and transversely cuts the web to form discrete leaves of a predetermined length; a lap roll to which the discrete leaves are delivered to arrange the leaves so that adjacent leaves overlap; a retard roll cooperating with the lap roll to overlap adjacent leaves; and a folding roll assembly which transversely folds each leaf to form at least three panels, with overlapping portions of adjacent leaves forming discrete panels, and wherein the machine is configured to accommodate one of the leaves between the lap roll and the retard roll so that said folding roll assembly folds each leaf so as to have a first set of panels which consists of an end panel and at least the next adjacent panel folded between a second set of panels that consists of an end panel and at least the next adjacent panel of an folded adjacent leaf, with the leaves being substantially identical and the panels of each leaf being substantially the same size and shape. - View Dependent Claims (9, 10, 11, 12)
