Definitions

  • This invention relates to an endless belt for use in a long nip press. More particularly, the invention relates to a press jacket used on a sleeve type of long nip press such as the Voith Flexonip press, or to belting used on a Beloit-type long nip press.
  • a press jacket or belting will be referred to as a belt.
  • a long nip press is used in a papermaking machine to dewater a fibrous web.
  • the belt is typically used in combination with a felt, which functions to support the web between the belt and a cylindrical press roller.
  • the belt is engaged by an arcuate pressure shoe, which includes a concave surface. The roller and the shoe cooperate to define a long nip through which the belt, felt and web pass to increase the dewatering of the web when compared to conventional nips on a papermaking machine.
  • Prior art long nip press belts have been constructed of a woven fabric coated and impregnated with a polymeric resin, such as polyurethane. Grooves may be formed in the outer surface of the belt for receiving water from the felt and web.
  • Representative patents of this type include Dutt U.S. Patent 4,946,731; Stigberg U.S. Patent 5,196,092; Cronin et al International Publication No. W087/02080 (International Application No. PCT/US85/01953); Dutt U.S. Patent 5,234,551; and Dutt U.S. Patent 5,238,537.
  • the prior art has utilized a synthetic base structure woven on a textile loom using multiple sheds or harnesses. Typically, this structure is stabilized and seamed to form an endless base.
  • the present invention teaches use of a non-woven synthetic base structure incorporating preformed loops joined with connecting rods to form a uniform endless base. Advantages offered by the invention include ease of manufacture in that preparation steps such as weaving and seaming are eliminated. Elimination of these process steps provides significant improvement in manufacturing flexibility. Additional benefits include improved uniformity and coatability of the base structure.
  • a long nip press belt is formed of a nonwoven spiral-type base or carrier which defines a first surface and a second surface.
  • the base includes a series of axially extending side-by-side spirals, each of which defines an internal space.
  • the spirals are interconnected by a series of substantially parallel connection rods extending through the internal spaces of adjacent spirals.
  • a polymeric resin coating is applied to the spiral base, and fills the internal spaces of the spirals.
  • the polymeric resin coating extends at least coextensively with the first and second surfaces of the base.
  • the polymeric resin coating defines a first surface which extends past the first surface of the base.
  • the coating further defines a second surface, which may either be coextensive with the second surface of the base or may extend past the second surface of the base.
  • the base or carrier is thus embedded within the polyurethane material to form a continuous composite belt structure, functioning to reinforce the polyurethane material and to maintain the integrity of the material during use in a long nip press environment.
  • the invention further contemplates a method of making a long nip press belt, substantially in accordance with the foregoing summary.
  • Fig. 1 illustrates a section of a spiral-type base or carrier 10 which forms a part of the long nip press belt of the invention.
  • the construction of base 10 is representatively illustrated in Gauthier U.S. Patent 4,567,077, the disclosure of which is incorporated by reference. This patent discloses use of the spiral-type material as a papermaking fabric which directly supports the web.
  • Base 10 is constructed of oppositely oriented axially extending spirals, shown at 12, 14.
  • Spirals 12 are oriented in one direction, e.g. with their upper portions being inclined leftwardly, and spirals 14 are oriented oppositely, e.g. with their upper portions inclined to the right between spirals 12.
  • Spirals 12 and 14 extend along parallel longitudinal axes. Referring to Figs. 3 and 5, spirals 12 and 14 define longitudinally extending internal passages 16, 18, respectively. Spirals 12 and 14 are arranged to overlap each other, so that the end portions of internal spaces 16, 18 overlap. Connector rods 20 extend through the overlapping portions of spiral internal spaces 16, 18, to connect spirals 12 and 14 into a continuous mat.
  • base 10 is constructed into an endless belt according to conventional technology, and is positioned about a pair of rolls 22, 24.
  • One of rolls 22, 24 is driven so as to provide movement of the top run of base 10 in a left-to-right direction.
  • a urethane coating apparatus is positioned over the upper run of base 10, and includes a nozzle 28 which deposits a coating of urethane, shown at 30, onto base 10.
  • a stationary box 32 defining a planar upper surface, is located below nozzle 28, and the upper run of base 10 extends through a space between the upper surface of box 32 and nozzle 28, with the lower surface of base 10 engaging the upper surface of box 32.
  • Urethane coating 30 is applied to base 10 by nozzle 28 in a substantially uniform thickness throughout the width of base 10.
  • the urethane material When applied to base 10, the urethane material is in a substantially liquid state, and functions to flow into and completely fill passages 16, 18 of spirals 12, 14, respectively, to a depth such that the lower extent of urethane coating 30 is coextensive with the lower surface of base 10.
  • Rolls 22, 24 are operated at a speed such that urethane coating 30 has set and hardened sufficiently when discharged from the upper surface of box 32 to form an integral, self-supporting sheet or mass with base 10 embedded therein.
  • This process of applying urethane coating 30 to base 10 is continued while base 10 is moved by rolls 22, 24 until the entire extent of base 10 is coated with coating 30 to thereby form an integral, endless urethane belt 33 reinforced by base 10 embedded therewithin.
  • urethane coating 30 defines a lower surface, shown at 34, which is coextensive with the lower surface of base 10. Coating 30 further defines an upper surface 36 spaced above the upper surface of base 10. Representatively, base 10 has a thickness of approximately 0.08 inches, and coating 30 has a thickness of approximately 0.13 inches, leaving upper surface 36 of coating 30 approximately 0.05 inches above the upper surface of base 10. This thickness of coating 30 has been found to provide sufficient flexibility and strength to belt 33 to withstand use in a long nip press environment.
  • upper surface 36 of coating 30 may be ground and polished in accordance with conventional technology.
  • Fig. 4 illustrates another arrangement for forming a long nip press belt according to the invention.
  • box 32 is positioned below the upper run of a pouring belt 38, which extends the entire width of base 10.
  • Pouring belt 38 is trained about a series of rolls 40, one of which is driven to provide movement of pouring belt 38 below base 10 at the same rate of speed at which base 10 travels between rollers 22, 24.
  • Base 10 and pouring belt 38 are arranged such that a space, shown at 42, is disposed between the lower surface of base 10 and the upper surface of belt 38.
  • a urethane coating 44 is applied to base 10 from nozzle 28. Coating 44 again functions to completely fill spaces 16, 18 in spirals 12, 14, respectively of base 10, and to pass through base 10 and space 42 into engagement with the upper surface of pouring belt 38. This results in a long nip press belt 45, as illustrated in Fig. 5.
  • Belt 45 is constructed substantially identically to belt 33 of Fig. 3 in which base 10 is embedded within and reinforces urethane coating 44. In this embodiment, however, urethane coating 44 defines a lower surface 46 which is spaced below the lower surface of base 10. As in the embodiment of Fig. 3, the upper surface 48 of belt 45 is disposed above the upper surface of base 10.
  • coating 44 has a thickness of approximately 0.17 inches, and base 10 again has a thickness of approximately 0.08 inches.
  • Upper surface 48 of belt 45 is disposed approximately 0.05 inches above the upper surface of base 10, and lower surface 48 of coating 44 is disposed approximately 0.04 inches below the lower surface of base 10. This thickness of coating 44 is sufficient to provide adequate strength and flexibility to belt 45 for use in a long nip press environment.
  • Rollers 40 are configured and arranged relative to nozzle 28 to provide support for coating 44 while it sets and hardens after application from nozzle 28 so that, when coating 44 and base 10 are discharged from the rightwardmost roller 40, coating 44 forms a self-supporting sheet or mass with base 10 embedded therewithin. The process of applying coating 44 to base 10 is continued while base 10 is moved by rolls 22, 24 until the entire extent of base 10 is coated with coating 44.
  • Coatings 30, 44 may be any satisfactory elastomer such as conventional urethane as is available from Uniroyal Chemical Corp. under its designation Adiprene Ribbon Flow. Alternatively, any satisfactory elastomer such as is known to those of ordinary skill in the art could be employed to form coatings 30, 44. Coatings 30, 44 are impervious and flexible, and have a sufficient hardness to withstand use in a long nip press environment. Representatively, coatings 30, 44 have a hardness of approximately 95 (shore A).
  • belts 33, 45 are adapted for use in a long nip press, shown generally at 50.
  • the press nip includes a cylindrical press roll 52, an arcuate pressure shoe 54, and belts 33, 45 constructed as described above disposed against pressure shoe 54 between shoe 54 and roll 52.
  • a rod 56 is pivotably mounted to pressure shoe 54 for applying the desired pressure to shoe 54.
  • a papermaker's wet press fabric 58 supports a fibrous web 60, being processed into a paper sheet. Fabric 58 and web 60 pass through long nip press 50 between roll 52 and the belt, such as 33, 45, for extracting water from web 60.
  • the construction and arrangement of the elements of press 50 are conventional in the art.
  • Belt 33 is arranged in press 50 such that its upper surface 36 is disposed against pressure shoe 54, in order to provide maximum wear resistance to belt 33.
  • the lower surface of base 10 bears against fabric 58.
  • Belt 45 is preferably oriented with its upper surface 48 bearing against supporting fabric 58 and its lower surface 46 bearing against pressure shoe 54. The presence of urethane material between lower surface 46 and the lower surface of base 10 provides resistance to wear imparted to belt 45 from pressure shoe 54.
  • Belt 45 may have its upper surface 48 grooved, drilled or otherwise patterned, as is known in the art, to provide additional void volume for water removal during processing.
  • Fig. 7 illustrates an alternative construction of a long nip press 62 in which belts 33, 45 constructed according to the invention are employed.
  • press 62 includes a cylindrical press roll 64, an arcuate pressure shoe 66, and belts 33, 45 constructed as described above disposed against pressure shoe 66 between shoe 66 and roll 64.
  • a rod 68 is pivotably mounted to pressure shoe 66 for applying the desired pressure to shoe 66.
  • a fibrous web 70 being processed into a paper sheet, is disposed between a pair of papermaker's wet press fabrics 72, 74. Fabrics 72, 74, web 70 and the belt, such as 33, 45, move upwardly through the nip between roll 64 and pressure shoe 66, for extracting water from web 70.
  • the construction and arrangement of the elements of press 62 are conventional in the art.
  • Belts 33, 45 are arranged in press 62 in the same manner as described above with respect to press 50.
  • Base 10 is oriented within belts 33, 45 such that connector rods 20, and the longitudinal axes of spirals 12, 14, extend perpendicularly to the machine direction of presses 50, 62, as illustrated in Fig. 1. With this arrangement, the segmental construction of base 10 provides flexing of base 10 as belts 33, 45 are trained about the roll of long nip presses 50, 62 and about the upper surface of pressure shoes 54, 66.
