摘要： A shoe press unit comprises a support beam, a shoe element movably supported on the beam, a pressing unit arranged between the beam and the shoe element for urging the shoe element away from the beam and toward a counter element, and a flexible belt that is arranged to slide over the pressing surface of the shoe element. An oil evacuation arrangement formed separately from the shoe element is affixed to the shoe element proximate an upstream edge region thereof. The oil evacuation arrangement has an inlet opening located such that a major portion of the excess oil expelled from between the belt and the shoe element passes through the inlet opening with a kinetic energy that is substantially undiminished from the initial kinetic energy of the oil as it exits from between the belt and the pressing surface of the shoe element.

摘要： A shoe press for applying pressure to a moving web of paper or the like includes a press shoe extending along a full width of the web being carried through a nip defined between the shoe and a backing member, a support for the shoe, and a plurality of articulated hydraulic loading cylinders arranged between the support and the shoe for urging the shoe toward the backing member to apply pressure to the web. Each loading cylinder includes a single piston and first and second cylinders attached to the shoe and to the support, respectively. The opposite end portions of the piston are slidably received within the cylinders so as to define working chambers in the cylinders which are pressurizable by hydraulic fluid for urging the two cylinders away from each other. The piston engages the cylinders at seals which enable the piston to pivot with respect to both cylinders about axes parallel to and perpendicular to the machine direction so as to enable the loading cylinders to accommodate deformations and thermal expansion of the shoe in the cross-machine direction and to allow the shoe to pivot about an axis perpendicular to the machine direction.

摘要： A press device with an extended press nip for pressing of a continuous paper or paperboard web comprises a press shoe, a backing member, a support, and a plurality of loading cylinders with main axes in their longitudinal directions. The press shoe can be moved between different positions. A stop member is arranged downstream of the press shoe for transfer between and fixation at different stop positions in the machine direction. At least some of the loading cylinders or the support comprise members eccentrically arranged with respect to one or some of the main axes, which members can be brought into different eccentric positions with respect to the main axes. The eccentric position and the stop position controls the position of the press shoe during the pressing, and thereby the pressure curve.

摘要： A shoe press for a paper or board machine, comprising a press shoe, a counter roll and a circulated flexible belt. A plurality of hydraulic loading cylinders for pressing the press shoe against the counter roll are arranged between a horizontal frame beam and the press shoe. The pistons of the loading cylinders are connected to the horizontal beam. The shoe press may have first hydrostatic compartments in the surface of the press shoe facing the counter roll and second hydrostatic compartments arranged between the side of the press shoe facing the loading cylinders and the loading cylinders. For supplying the working chambers of the loading cylinders and/or the first and/or second hydrostatic compartments with hydraulic fluid, there is arranged a duct which extends in the longitudinal direction of the press shoe and is common to all working chambers and the first and second hydrostatic compartments, respectively. The duct for connecting the working chambers is at least partially formed by tubular duct members which are formed separately from the frame of the shoe press and which extend between and fluidly connect adjacent pairs of loading cylinders. In a preferred embodiment, the tubular duct members are slidably inserted in bores formed through the pistons of the loading cylinders, and a seal is disposed between the duct members and the bores for sealing of the joints.

摘要： In a roll nip (5) formed between a shoe press roll (1) having a concave, plane or slightly convex press shoe (11), a flexible jacket (15) and a hot counter roll (3), the jacket (15) may be damaged by the heat from the counter roll (3) upon a web break. To avoid this, the roll nip (5) is opened by removing one of the press shoe (11) and the hot counter roll (3) from the other, so that the jacket (15) resumes a generally cylindrical shape having an arched portion located across the shoe (11). Then, a force is applied inside the roll jacket (15), directed away from the roll nip (5), to tension the roll jacket (15) over the leading edge and the trailing edge of the press shoe (11), so as to reduce the height of arch of the arched portion over the shoe (11) sufficiently to ensure removal of the jacket (15) from contact with the hot counter roll (3). Preferably, the force against the inside of the jacket is applied by means of a tensioning shoe (61). Suitably, the tensioning shoe is operated by a linear actuator (59), e.g. a fluid force actuator, carried by a support beam (17) that extends axially through the flexible jacket (15).
