  • Publication number: 20160120377
    Abstract: A of web material for hygiene products includes at least one folded continuous web material, and a first connector and a second connector, adapted for interconnection of the first end surface of the stack to a second end surface of another, similar stack. The first connector includes a first connection surface consisting of a first material, and the second connector includes a second connection surface consisting of a second material; said first and second materials having properties that, upon bringing said first and second surfaces into contact with each other, the surfaces attach to each other by surface adhesion so that the surfaces are repeatedly removable from and reattachable to each other while leaving the surfaces substantially unaltered, whereby a connection between a first/second connector of the stack and a second/first connector of a similar stack is accomplished.

  • Patent number: 9004313
    Abstract: A stack of hygiene sheet products including first and second webs that are interfolded with each other. The stack includes a top panel of the first web and a top panel of the second web, wherein the top panel of the first web overlays the top panel of the second web but has been cut away so that the top panel of the second web is revealed by the top panel of the first web. An adherence layer is placed on the top panel of the first web and the top panel of the second web and is exposed at the top of the stack so that it can adhere to an adjacent stack so that when the last sheets of the adjacent stack are pulled through a dispenser opening of a dispenser, the first and second sheets are pulled securely through with it as a result of the direct adherence.
