  • Patent number: 6197157
    Abstract: A press device for draining and/or smoothing, or shaping the surface and controlling the sheet structure of fibrous pulp webs with a surface weight of under 100 g/m2, such as the fibrous pulp webs used to make graphic papers. The device has a press area which includes at least one press nip through which, during operation, the fibrous pulp web is fed at a velocity of at least 1200 m/min, under simultaneous impingement by pressure. The press area includes at least two press zones subsequent to one another. The device is further characterized by a K value of at least 2.5 kPa·s·m. This K value is the product of L1 and Itot. L1 is the length of the first press zone, measured along the direction in which the web runs, and Itot is the total press impulse operating on the fibrous pulp web in the entire press area.

  • Patent number: 5997694
    Abstract: A press arrangement of a paper or cardboard machine for the treatment of a fibrous pulp sheet in a press opening that is extended in the run direction of the fibrous pulp sheet. The press opening is defined by two press surfaces, at least one of which is constructed of a flexible press sleeve that is guided over at least one press shoe. The flexible press sleeve is further able to press against the opposing press surface with the aid of the press shoe due to the creation of a fluid cushion between the press shoe and the press sleeve. The press shoe is thus able to be tensioned such that a resulting main press force is exerted in a direction that runs substantially perpendicular to the fibrous pulp sheet being guided through the press opening. A lever is designed to load the press shoe with an positive or negative force that acts on the press shoe substantially perpendicular to the resulting main press force.

  • Patent number: 5935385
    Abstract: A press device, e.g., a shoe press device, for treating a sheet of material, e.g., paper or cardboard, in an elongated press gap elongated in a travel direction of the sheet of material. The press device may include a flexible roll jacket that runs around a stationary carrier, an opposing face that forms the elongated press gap with the flexible roll jacket, and at least one of a hydrodynamically and hydrostatically lubricated support element supported on the carrier. The support element may include a compression face adapted to a shape of the opposing face and at least one cloth belt guided through the elongated press gap. The support element may further include an entry face for the flexible roll jacket and for the cloth belt and positioned before the compression face in the travel direction of the sheet of material. A lubricant aspiration device is located before the support element in the travel direction, and is spaced from the roll jacket during normal operation.

  • Patent number: 5925219
    Abstract: Shoe press for treating a material web that may include a press shoe to be pressed against an opposing element, e.g., a counter roll, with a fluid permeable press jacket and a felt belt being positionable between the press shoe and the opposing element, and a plurality of support elements including cylinder devices and pistons supported on a carrier. The press shoe may have a concave-shaped press face forming a nip with the opposing element such that the nip has a predetermined longitudinal span. The press shoe may be movable on the plurality of support elements, and the pistons of the plurality of support elements may carry the press shoe to permit a tilting movement of the press shoe both in a web travel direction and lateral to the web travel direction. A stop may support the press shoe in the web travel direction and may absorb horizontal forces acting on the press shoe.

  • Patent number: 5908537
    Abstract: The invention relates to a roll press including at least three rolls forming several press nips for the treatment of a web of material. One press roll comprises a very flexible roll shell which is rotatable around a fixed support and is mounted on the support by at least one support element which has a concave support surface for defining a wide press nip with a cylindrical backing roll. The backing roll forms an additional press nip with at least one not sag-controlled roll. To obtain as uniform as possible a press nip between the backing roll and at least one additional roll which is without sag control, the circumference of the roll shell of the backing roll decreases axially towards its ends, i.e., that roll may be crowned.

  • Patent number: 5895007
    Abstract: A method and device for winding a paper web to form a reel. The web is wound onto a shell that is predominantly centrally driven to introduce a torque that winds the web on the shell into a reel. A pressure element extends over the width of the web and acts continuously on the outer surface of the reel being wound in order to squeeze out air. A web threading roll comes adjacent the shell during web threading. Once the web is threaded, the shell is moved generally horizontally from the web threading toward the main winding position where the web is wound. A compensation device supports the reel being wound. The first pressure element in contact with the reel may move away, and a second pressure element closer to the compensation device may press upon the reel, after the first pressure element has moved away.
