摘要：: The present invention relates to a stack of folded web material for hygiene products, such as paper or nonwoven products, said stack comprising: At least two webs (1,2), the webs including: A first web (1) divided into individual sheets by means of lines of weakness (4); and A second web (2) divided into individual sheets by means of lines of weakness (4); Said first and second webs (1, 2) being interfolded with one another so as to form said stack (3): and.. wherein the first web (1) and the second web (2) are arranged in said stack (3) such that the lines of weakness (4) of the first web (1) and the lines of weakness (4) of the second web (2) are offset with respect to one another along the webs (1, 2); Each line of weakness (4) having a separation strength, being the force required to separate an individual sheet from the web along said line of weakness(4). The first web and the second web (1, 2) are joined to each other at a plurality of joints forming a plurality of individual sheet interconnections (5), wherein each individual sheet interconnection is formed by the joint or joints connecting an individual sheet of the first web (1) with an individual sheet of the second web (2); and each individual sheet interconnection (5) having a separation strength, being the force required to separate the two individual sheets of the first and the second web (1, 2) from each other, such that the joint or joints creating said individual sheet interconnection (5) are broken, wherein the separation strength of the individual sheet interconnections (5) is less than the separation strength of the lines of weakness (4).
