A winding device for a substantially electrically insulating web material having a winding roller on which the web material can be wound, characterized in that an apparatus exists for transferring an electric charge to the web material on the winding roller, and/or when deflecting to the winding roller, and the apparatus for transferring an electric charge is connected to at least one electrical high-voltage source with a positive or negative polarity.

A method of winding a glass ribbon (10), including: winding an interleaving material (20) and the glass ribbon together to produce a roll (40); and tensioning the interleaving material so as to control a roll inter-layer pressure. By controlling the roll inter-layer pressure, the roll can be formed with straight side walls. The tension in the interleaving material can be controlled so as to be greater than 0 and ≦0.25 pounds per linear inch of width of interleaving material. Also, there is provided an apparatus for winding glass ribbon together with interleaving material into a roll. The apparatus includes: an interleaving material supply path; a glass ribbon supply path; a roll winding mechanism (46); and a means (26) for applying tension to interleaving material traveling along the interleaving material supply path, as the interleaving material is wound into roll (40), so as to produce a pressure between the layers of the roll.

A method for winding up a glass ribbon is provided, in which, prior to winding up the glass ribbon, the two surfaces of the glass ribbon are each initially treated with a water-containing medium and subsequently dried so as to produce a defined content of water molecules on the two surfaces, by achieving a saturation of the surfaces of the glass ribbon with water, without bringing about an excess of water molecules. A glass roll is produced in which the electrostatic charge of the glass surface is reduced and, as a result, any undesired excess adherence of the glass surface to an interleaf material is prevented and, in this way, glass breakage, in particular during winding up and/or unwinding of the glass roll, can be markedly reduced.

A package of flat material in a flat profile and a method for making the package. Flat material is wound around a core having hollow channels that are coupled by engagement with extruding pins from a member. The member is mounted on an axis that rotates, causing the member to rotate. The rotation winds the flat material onto the core. The final package of flat material has a flat profile, which may be a convenient shape for storage in small and confined places.

A winding device includes a first roller that winds label roll paper that is composed with a continues base sheet, a plurality of labels and a marginal portion, a second roller that winds the marginal portion peeled off the label roll paper, a drive part that generates a driving force for the second roller to rotate, a drive transmission control part that is provided between the drive part and the second roller such that the driving force is transmitted to the second roller from the driving part, and stops transmitting the driving force to the second roller if a load placed on the second roller exceeds a prescribed load, a detection part that detects a rotation of the second roller, and a control part that determines a cutoff of the marginal portion based on the rotation of the second roller detected by the detection part.

A brake is provided for an idler roll (10) of a fiber web machine, in particular of a slitter-winder, which idler roll (10) has an outer shell surface (13). The brake (20) is located outside the outer shell surface (13) of the idler roll (10) in close vicinity of the idler roll (10) in a non-contacting position. The brake (20) has a permanent magnet (25), which is configured to be moved from non-braking position to a braking position and vice versa by an actuator or cylinder (35, 45).

Described herein are methods and systems for reducing the tail on a parent roll. The system may comprise a web tail extending from a parent roll supported by an unwind stand. The system may further comprise one or more nozzles positioned below the web tail and configured to facilitate the rewinding of the web tail about the parent roll. The web tail may be rewound about the parent roll in a direction opposite to that which the web was initially wound about the parent roll. As a result, the length of the web tail extending from the parent roll may be reduced and is less likely to lengthen as the parent roll is ejected from the unwind stand.
