The invention relates to a device () which is used to press a pressure shoe () against a counter surface, comprising at least one at least partially flexible pressure body () which is supported on the bearing body (), said pressure body comprising at least one cavity () which can be impinged upon by pressure fluid in order to produce a predetermined pressing force over a corresponding pressure body volume.

Pressing device

A shoe press, in particular for a paper machine, comprising a pair of rolls, with one roll having a flexible roll sleeve that rotates around a stationary carrier and support devices, the flexible roll sleeve having axial end areas and being mounted on a carrier in a radially rotatable manner at each of its axial end areas over the support devices, each roll having a shoe with a flat support surface, the support surface of the shoe of one roll supporting an interior side of the roll sleeve, the support surfaces being arranged essentially parallel to each other to create a press opening therebetween, and at least one of the support devices being radially flexible, and in particular elastic.

Shoe press

Press device to treat a fibrous pulp web that may include a shoe press roll and a mating roll. The shoe press roll and the mating roll may be positioned to form a press nip, and at least one endless belt guided through the press nip and forming a substantially non-flexible and rigid drive element at least partially driving the press device.

Press device

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.

Press device with oil aspiration device

A shoe press device for treating a web, particularly for dewatering a web. A shoe press roll has a beam and a flexible press jacket around the beam. A press shoe on the beam presses the press jacket against a backing roll to define a press nip. Support elements supported on the beam press on the shoe. The support elements are in a first plurality along the shoe and a respective second plurality toward each end of the shoe. The second support elements are smaller in size with reference to their pressure area on the shoe, and there is one or more rows of second pressure elements at each end of the shoe. Different respective pressures may be applied to the main and second pluralities of support elements. The backing roll may be a sag adjustment roll including a rotatable roll jacket and support elements in the sag adjustment roll pressing on the roll jacket. The support elements in the sag adjustment roll may be similar in size with reference to the area exposed to the roll jacket and similar to or greater by one in number than the first support elements for the shoe press roll. Various devices control the pressure to the first, second and sag adjustment roll support elements.
