Definitions

  • the present invention relates to a shoe press roll which presses a web material with a long nip width, and more particularly, to an elastic sleeve for a shoe press formed of an elastic material in the shape of a tube, a manufacturing method thereof and a shoe press roll employing the same.
  • a shoe press is used in a dehydrating press process in the paper manufacturing industry. To put it briefly, the shoe press forms a pressing region with a large width by pressing an elastic belt (sleeve) toward an opposed press roll by using a press shoe having a predetermined width in the running direction and performs a pressing (dehydrating) process for a web material (wet paper web) which is an object to be pressed in this pressing region.
  • a normal roll press applies linear pressure to the object to be pressed, according to the shoe press, since the press shoe has the predetermined width in the running direction, area pressure can be applied to the pressed object.
  • the shoe press is used for a calender in which a web material such as paper, a magnetic tape and the like is glazed in the paper manufacturing industry, the magnetic recording medium manufacturing industry and the like.
  • Japanese Patent Publication No. 2-53543 discloses a press roll which forms a press nip in cooperation with a counter roll
  • Japanese Unexamined Patent Publication No. 2000-178892 discloses a method and an apparatus for calendering a fiber web using a surrounded shoe roll.
  • FIG. 3 is a sectional view showing a shoe press apparatus 100 taken along the direction perpendicular to an axis line
  • FIG. 4 is a sectional view showing the shoe press apparatus taken along the axis line.
  • the shoe press apparatus 100 comprises a press roll 101 , and a shoe press roll 102 which is opposed to the press roll 101 .
  • the press roll 101 is formed of a hard material such as metal, stone, synthesized stone, ceramic and the like and it is rotated at high speed.
  • the shoe press roll 102 comprises a support shaft 103 which is not rotated substantially, a press shoe 104 set on the support shaft 103 , a sleeve support member 105 mounted on each end of the support shaft 103 , and an elastic sleeve 106 which covers the support shaft 103 and the press shoe 104 and has an end supported by the sleeve support member 105 .
  • the elastic sleeve 106 is mounted such that it is pulled in from one end of the shoe press roll 102 so as to cover the outer peripheral surface of the sleeve support member 105 .
  • the sleeve support member 105 is in the shape of a disk, which constitutes an end face of the shoe press roll 102 .
  • a bearing is interposed between an inner diameter of the sleeve support member 105 and the support shaft 103 , and the sleeve support member 105 can be rotated around the support shaft 103 .

  • the shoe press roll 102 is operated in a state the elastic sleeve 106 is swollen.
  • a web material 107 such as a wet paper web which is an object to be pressed is passed between the elastic sleeve 106 and the press roll 101 .
  • the surface of the press shoe 104 has a predetermined width in the running direction and it is gently curved so as to correspond to the surface of the press roll 101 . Therefore, a wide pressing region is formed between the press roll 101 and the shoe press roll 102 , and the web material 107 is pressed in this pressing region.
  • the elastic sleeve 106 Since complex force such as compressive force, tensile force and the like is applied to the elastic sleeve 106 on the shoe press roll 102 during the operation, the elastic sleeve 106 has been conventionally formed of a composite material comprising an elastic material and a reinforcing material such as a base cloth in order to maintain its strength and dimension against the force applied during the operation.
  • the elastic sleeve 106 is extended because of fatigue and it is gradually swollen in the diameter direction because of pressure from the inside also.
  • the elastic sleeve 106 flaps during the operation and the rotation becomes unstable. As a result, the web material is damaged or its quality deteriorates, and a scratch, abrasion or crack is generated in the elastic sleeve 106 .
  • an object of the present invention to provide an elastic sleeve for a shoe press which is prevented from being swollen, to improve durability and maintain running stability for a long period, its manufacturing method and a shoe press roll using it.
  • an elastic sleeve for a shoe press in the present invention, it is formed of an elastic material into the shape of a tube to be used as an outer cylinder of a shoe press roll which presses a web material with a long nip width and characterized in that an inner diameter is gradually reduced from both ends to a center in an axial direction.
  • a shoe press roll in the present invention comprises a support shaft which is not rotated substantially, a press shoe set on the support shaft, a sleeve support member which is mounted on each end of the support shaft and can be rotated around the support shaft, and an elastic sleeve which covers the support shaft and the press shoe and has an end supported by the sleeve support member, in which the press shoe presses the elastic sleeve from the inside to the outside, and the elastic sleeve slides on the press shoe and rotates around the support shaft with the sleeve support member, and it is characterized in that the elastic sleeve has an inner diameter gradually reduced from both ends to a center in an axial direction.
  • the elastic sleeve since the inner diameter of the elastic sleeve is gradually reduced from the both ends to the center in the axial direction, the elastic sleeve can be prevented from being swollen by use.
  • a method of manufacturing an elastic sleeve for a shoe press in the present invention comprises a step of stretching a sleeve formed of an uncured or imperfectly cured elastic material between two rolls, a step of moving the two rolls in directions apart from each other, a step of deflecting the two rolls in such directions that center parts thereof are moved close to each other by utilizing tension of the sleeve, and a step of perfectly curing the elastic material while rotating the sleeve in this state.
  • the elastic sleeve for the shoe press in which the inner diameter is gradually reduced from the both ends to the center in the axial direction can be easily manufactured.
  • a difference in inner diameter between the both ends and the center of the elastic sleeve is 1 mm to 15 mm.
  • the difference in inner diameter is selected from the above range, the elastic sleeve is not swollen by relatively short-time use and the elastic sleeve can be easily mounted.
  • a lower limit value of the difference is 5 mm, and an upper limit value thereof is 10 mm.
