A web processing system is provided. The web processing system supplies a processed continuous web of material to a cutting arrangement. The cutting arrangement forms sheets from the continuous web of material. The sheets are then supplied to multiple folding arrangements such that a single web of material is used to supply sheets to multiple folding arrangements.

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.

The folding roller includes a rotation axis and at least a gripping member extending longitudinally along the folding roller, controlled by at least a piezoelectric actuator. The piezoelectric actuator causes a pivoting movement of the gripping member about its pivoting axis parallel to the rotation axis of the folding roller.

A folding machine for folding fiber products and fiber products formed and stacked thereby are disclosed. The folding machine includes two folding devices, each of which includes a cutting device, a delivery wheel, a folding-line wheel, a platen wheel, and a folding wheel. The cutting device cuts the fiber product and transports the cut fiber product to the delivery wheel. The folding-line wheel is adjacent to the delivery wheel for making a first folding line on the fiber product carried by the delivery wheel, and then the platen wheel folds the fiber product along the first folding line. Subsequently, the once-folded fiber product is transported to the folding wheel. The folding wheels of the two folding devices are adjacent to each other and are used to fold the fiber product passing therethrough for a second time, and thus fiber products with three folds are formed.

Embodiments are directed to a dispensing device and methods of using a dispensing device having an improved out indicator. The dispensing device includes a housing having a cavity. A tissue stack is disposed within the cavity, the tissue stack including a plurality of tissue sheets folded along a crease. An aperture is formed in a top surface of the housing such that a tissue sheet is removable from the cavity through the aperture. A portion of the tissue sheets includes an out indicator formed along a centerline of each tissue sheet and across the crease.
