Roller for conveying a web or sheet of paper in paper converting machines and conveying method thus obtained
An improved conveying roller for a web or a sheet in a paper converting machine comprises a first cylindrical tubular body having a plurality of radial holes arranged in substantially longitudinal rows, and a second fixed tubular body arranged coxially within the first cylindrical tubular body. The first cylindrical tubular body is capable of rotation relative to the second fixed tubular body. Slidable sealing elements are positioned between the first cylindrical body and the second fixed tubular body to define at least one suction or vacuum chamber. The chamber is suitable for being brought selectively in communication with at least one row of the radial holes during the relative rotation of the bodies.

Fiber product folding apparatus
A fiber product folding apparatus includes a first dashed-line cutting device used to form a plurality of first dashed lines on a first fiber product. Through control of the rotational speed of the first dashed-line roller, the interval between adjacent first dashed lines is adjusted. A first severing device receives the first fiber product with the first dashed lines by a predetermined length and cuts off the first fiber product. A second dashed-line cutting device is used to form a plurality of second dashed lines on a second fiber product. Through control of the rotational speed of the second dashed-line roller, the interval between adjacent second dashed lines can be adjusted. A second severing device receives the second fiber product that includes the second dashed lines by a predetermined length and cuts off the second fiber product. Finally, the first fiber product and the second fiber product are conducted to pass between a first folding roller and a second folding roller to proceed with folding. Since the dashed line interval of the fiber products is the size or length of a single sheet of fiber product, controlling the rotational speeds of the dashed-line rollers would allow for adjustment such that folding can be performed for multiple forms.

Dispenser and stack of sheet products
A dispenser and a stack combination. A dispenser that contains a stack of sheet products and which defines a dispensing path from a product reservoir containing and holding the stack to a dispensing opening through which the sheet products are dispensed. A stack of interfolded webs wherein the lines of weakness of one web are offset from the lines of weakness of another web in a longitudinal direction.

Stack of interleaved wipes
A stack of interleaved wipes where the first wipe (10) will have its first crease (15) drawn to the region of or partially through an opening (1) in a container (2) of the wipes, so that it can be grasped and drawn through the opening. The second wipe (20) and those below are in their interleaved arrangement. The crease (25) together with adjoining parts of the portions (21, 24), is enfolded in a fold (170) of the wipe (10) formed by its portions (11, 16) and the crease (17). The wipe (10) is the wipe next to the wipe (20) on its side opposite from its portions (24, 26). The crease (27) at the opposite edge from crease (25) of the main portion (21) forms with the main portion (21) and the second folded portion (26) a fold (270) which enfolds the fold (350) of the wipe (30).

OUT INDICATOR SHEETS
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.
