Definitions

  • Webs of material are transported through spans that typically have web stabilizers, such as shown in U.S. Patent No. 4,321,107 and U.S. Patent No. 5,738,760 .
  • the webs move at a relatively high speed through the spans and across the stabilizers.
  • At least two forces are applied: at least one force is applied to the outside sheet edge region of the stabilizer; and at least one force is applied to the main body of the web.
  • the force is applied to the outside sheet edge region of the stabilizer to draw the side edge of the web to the stabilizer.
  • the edges of the web are kept in-line with other portions of the web moving across the stabilizer. Minimizing curling of the side edges reduces stresses in the web material, reduces web breaks and may improve characteristics of the web material because the side ends are subjected to less stress and stretching.
  • the force applied to the outside sheet edge region of the stabilizer may be formed by air movement away from the web edge.
  • compressed air or a vacuum may be applied at or near the sheet edge to draw air from the edge of the web to create a suction pushing the edge of the web towards the stabilizer.
  • air may be forced or drawn through a gap at the sheet edge.
  • the gap is generally parallel to and adjacent the side edge of the web. As the air flows through the gap, a pressure drop forms at the sheet edge that draws the side edge of the web towards the sheet edge of the stabilizer.
  • the air movement over the sheet edge is preferably in a direction flowing away from the web, perpendicular to the sheet edge, and aligned with the intended elevation of the web.
  • the air movement may be directed in other directions, including towards or away from the stabilizer.
  • the air flow should create a low pressure between the web and the sheet edge of the stabilizer such that the low pressure pulls the side edges of the web towards the sheet edge.
  • the force is applied to the main body of the web to inhibit the web from fluttering as it passes near the stabilizer.
  • the air movement over the sheet edge is preferably in a direction flowing parallel or substantially parallel with the flow of the web.
  • the air movement may be directed in other directions, so long as some vector of the air flow is concurrent with the direction of web travel.
  • the air flow should create a buffer zone between the web and the stabilizer such that fluttering of the web is inhibited.
  • FIGURE 1 is a schematic diagram of a web stabilizer in accordance with an aspect of the present invention.
  • FIGURE 2 is a schematic side-view diagram of a web stabilizer in accordance with an aspect of the present invention.
  • FIGURE 3 is a schematic cross-sectional diagram of a web stabilizer in accordance with an aspect of the present invention.
  • FIGURES 1-3 are schematic diagrams of a web stabilizer 100 and a web moving below the stabilizer.
  • a moving fluid preferably a gas such as air, is introduced along two portions: substantially widthwise near the outside edge of the web and substantially lengthwise along the stabilizer.
  • gaps 102 may introduce air substantially perpendicular to the direction of web travel. Although illustrated as perpendicular to the direction of web travel (i.e., at 90° as measured from the direction of web travel), any suitable angle may be employed. For instance, the "side air" introduced via the gaps 102 at the sides of the web travel may be at any angle between 0 and 90° (such as at substantially 75°) or even any angle at 90° ⁇ 60° as measured from the direction of web travel.
  • gaps 104 may introduce air substantially parallel to the direction of web travel (i.e., substantially at 0° as measured from the direction of web travel). Other suitable angles may be employed.
  • the "step air” may be at any angle ⁇ 90° as measured from the direction of air travel.
  • the stabilizer 100 may be designed to handle any suitable size of web, such as webs that are approximately 212 inches wide. Smaller and larger widths are contemplated, and the precise width of web is relatively unimportant to aspects of the present invention.
  • the moving fluid e. g. , air
  • the moving fluid e. g. , air
  • the moving fluid introduces gaps 102 and gaps 104 create forces that stabilize the web, possibly inhibiting curling and/or fluttering. Reducing curling and/or fluttering should, in many instances, reduce sheet breaks and improve performance and the speed potential of the web machine.
  • the machine may be employed in a process for making tissue, towel, paper, board, plastics, and/or polymers. It may be possible to use at least certain embodiments in connection with making sheets of malleable metals or other thin films.
  • the stationary web stabilizer 100 may be a generally rectangular device having a substantially flat bottom surface, as more fully described herein.
  • the web generally moves at a high velocity over the flat bottom surface. The movement of the web creates a pressure difference on opposite sides of the web that draws the web towards the surface.
  • the center portion of the web may be adjacent the bottom of the stabilizer.
  • the side edges of the web may curl away from the bottom of the stabilizer. There is a desire to eliminate the curling and force the side edge into the same plane as the center portion of the web. Furthermore, there is a desire to simultaneously stabilize the center portion of the web.
  • a moving fluid e.g., air
  • a moving fluid is directed away from the side edge to generate a transverse force applied to the side edge and, at the same time, a moving fluid is directed in the direction of web travel to generate a congruent force applied to the web.
  • the transverse force causes the side edge of the web to move towards the outer edges of the stabilizer, while the congruent force prevents the web from impacting the stabilizer.
  • air is used to refer to a moving fluid that is preferably atmospheric air but may be other gases and liquids and includes using vacuum or other negative pressures.
  • the moving fluid may alternatively comprise inert or substantially inert gasses (e.g., noble gasses, nitrogen, etc.) may be used.
  • the moving fluid may facilitate a reaction in or on the web. For instance, the use of oxygen may facilitate an oxidation reaction on the web surface.
  • the air may flow through any suitable configuration of tubes and/or pipes and may be delivered and/or controlled separately with respect to gaps 102 and 104.
  • at least one hollow beam with air nozzles delivers air to gaps 102 and/or 104.
  • Gaps 102 and/or 104 may include air knives, pipes, beams or bars with internal air passages and air nozzles formed by drilled holes or slots along the length of the device.
  • the devices are preferably mounted on or in the vicinity of a bottom surface of the stabilizer 100 and, particularly, at or outside the sheet edge region of the bottom surface and along the width of the stabilizer 100.
  • the stabilizer may be positioned below the web and have an upper surface adjacent the web, where the air movement device is mounted on top of the upper surface.
  • the surface of the stabilizer adjacent the web may be flat, arched, contoured or have other shape which faces the web.
  • gaps 102 and/or gaps 104 are at a pressure and velocity sufficient to influence the position and orientation of the web edges and web body such that the entire web, including the web's edges, is rendered more stable from the reduced flutter and curl.
  • the surface of the stabilizer 100 adjacent the web may be smooth or rough, a bottom (or top) surface and a planar surface.
  • Air through gap 102 may be introduced beyond the web's edge in a horizontal dimension, such in a range of zero to twelve inches from the web edge.
  • the air may be introduced such that the air flows along the surface of the stabilizer. In some embodiments, the air flows away from edge of the web in a direction substantially parallel to the surface of the stabilizer.
  • FIGURE 2 schematically illustrates a side-view of stabilizer 100 showing gaps 106 and 108 for "side air" supplied at least partially perpendicularly to the direction of web travel (as shown by the arrow).
  • the side air stabilizes the edges of the web during operation, and the holes or perforations 110 and 112 in gaps 106 and 108 supply the air in a direction at least partially orthogonal to the side-view depicted (i.e., the air through holes or perforations 110 and 112 are directed partially towards the viewer).
  • Gaps 106 and 108 are defined by the difference in location of surfaces 130 and 132.
  • the web stretches along the width of stabilizer 100 in a plane substantially parallel to surfaces 130 and 132.
  • gaps 116 and 114 supply the "step air" in the direction of web travel.
  • Gaps 116 and 114 may be of any suitable height, such as, for example, any height in the range of 1/16" to 3/4" (or greater).
  • These gaps may have a number of holes or perforations that supply air to stabilize the web during operation. For instance, there may be thousands, e.g., about 3600, of perforations for each step. These holes or perforation may each be about 0.001" in diameter or larger (e.g., 0.01").
  • alternative embodiments may include a single gap supplying "side air.”
  • other embodiments may include three or more gaps for supplying side air. It may be preferable to have the same number of slots supplying "side air” as supplying "step air”.
  • surfaces 130 and 132 have a stepped configuration, in which the gaps 116 and 114 that supply the "step air" alter the surface of the stabilizer 100.
  • the surfaces 130 and 132 are discontinuous to the direction of the web travel, and the direction of the web travel is substantially parallel to the stepped surfaces 130 and 132.
  • Shafts 118, 120, 122, 124, 126, and 128 supply a fluid (e.g., air) individually, selectively, and/or collectively to both the gaps for side-air and step-air.
  • a fluid e.g., air
  • These shafts may additionally or alternatively provide mounts for mounting the stabilizer in place.
  • the shafts are connected to gaps 102 and 104 by any suitable equipment, such as, for example, hoses, pipes, etc.
