摘要： 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.

摘要： 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.

摘要： Shoe press unit and method for treatment of a fibrous pulp web. The shoe press unit includes at least one press shoe, an opposing surface, a flexible press belt guided over the press shoe, and at least one force element composed of a cylinder/piston unit supported on a carrier. The at least one force element presses the press belt against the opposing surface to form a press zone elongated in a web run direction, and the cylinder/piston unit include a pressure chamber having at least one pair of cylinder/piston subunits successively positioned in the web run direction. Pressure fluid lines are coupled to respective ones of the at least one pair of cylinder/piston subunits to separately supply pressure fluid to each cylinder/pressure subunit to impart a tilting moment long a tilt axis substantially perpendicular to the web run direction. The method includes supplying a pressure fluid to a first and second pressure fluid line from a common pressure fluid source at a source pressure, supplying pressure fluid through the first pressure fluid line at a first fluid pressure to a first subunit of the at least one pair of cylinder piston subunits, supplying pressure fluid through the second pressure fluid at a second fluid pressure to a second subunit of the at least one pair of cylinder piston subunits, and maintaining a sum of the first and second fluid pressures to be substantially equal to the source pressure.

摘要： 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. The additional positive or negative forces transfer a tilting moment to the press shoe whereby the press shoe tilts around a respective tilting axis. The tilting axis extends substantially perpendicular to the run direction of the fibrous pulp sheet and in the transverse direction of the press arrangement. Thus, the additional forces can, substantially, independently influence the pressure profile in the press opening, set along the run direction of the fibrous pulp sheet.
摘要翻译： 一种纸或纸板机的压制装置，用于在沿着纤维纸浆片的行进方向延伸的压力开口中处理纤维纸浆片。 压力开口由两个压制表面限定，其中至少一个是由至少一个压靴引导的柔性压力套筒构成的。 由于在压靴和压榨套筒之间产生流体垫，柔性压力套筒还能够借助于压靴而压靠在相对的压力表面上。 因此，压靴能够被张紧，使得所产生的主加压力沿着基本上垂直于被引导通过压力开口的纤维纸浆片的方向施加。 杠杆被设计成以正或负的力加载压靴，其作用在基本上垂直于所产生的主压力的压榨机上。 附加的正或负力将倾斜力矩传递到压靴，由此压力靴围绕相应的倾斜轴线倾斜。 倾斜轴线基本上垂直于纤维纸浆片的行进方向并且沿压力装置的横向方向延伸。 因此，额外的力可以基本上独立地影响沿着纤维纸浆片的行进方向设定的压力开口中的压力分布。

摘要： A press blanket for a press device in a paper making machine, or the like, is formed of an elastomeric blanket material and fully embedded layers of reinforcement threads. The radially inner layer is formed of longitudinal threads which extend parallel to the axis of the press blanket. The radially outer layer is formed of circumferential threads which are wound in the direction of blanket motion and are wound generally helically. The threads are fully surrounded by the layer of homogeneous elastomeric material, that is formed from a single pouring. The circumferential threads have a diameter of at most 1/500 of the outside diameter of the fully rounded press blanket. In a unit area of the press blanket, the tensile strength of the circumferential threads is at least 40% greater than the tensile strength of the longitudinal threads. An apparatus for forming such a press blanket includes a rotatable pouring cylinder on which the longitudinal threads are supported, an elastomeric material pouring nozzle which moves longitudinally over the pouring cylinder and an unwinding device for delivering the circumferential threads in a helical manner and located just after the pouring nozzle above the pouring cylinder.
