Definitions

  • Glass sheet is formed from a mass of molten glass, for instance by rolling, and is transported horizontally while cooling it from its plastic state to a state in which it can be mechanically handled without damaging its surface.
  • the problem has been difficult. It has been attempted to mount nozzles on a pressure chamber, or to provide the chamber with orifices through which, the gas can flow, providing orifices to evacuate the gas from between the blowing nozzles or apertures.
  • the invention provides apparatus fortransporting a sheet or ribbon of glass on -a gaseous cushion to the exclusion of all contact with a solid support in the region where the glass surface can be readily damaged.
  • apparatus for the support of moving sheets, ribbons, and the like on a cushion of air which comprises a flat surface, pneumatic pressure means connected thereto, a series of slots of emission extending through the flat surface from the pressure means transversely of the course of the sheet and substantially across its full width, a series of slots of exhaustion in the flat surface parallel to the slots of emission, the slots of emission and exhaustion being generally arranged so that each pair of slots of exhaustion has between them two slots of emission and, between the two slots of emission, part of the flat surface.
  • a novel process involves the supporting of hot glass sheet moving in a selected direction out of contact with a flat surface which comprises establishing. a series of blades of upwardly moving gas transversely to its line of motion and substantially throughout the width of the sheet, establishing linear apertures of evacuation between some of the said blades and establishing linear zones of static pressure substantially fully across the sheet between alternate pairs of the said blades.
  • the apparatus contains orifices of emission for the gas associated with orifices of evacuation, all theorifices being slots which extend across the line of motion of the sheet and substantially the full width of the sheet.
  • Each slot of evacuation is separated from the next by two slots of emission which are choked to establish a substantial loss of head, the slots of evacuation being substantially larger in order to permit outflow with only negligible loss of head.
  • the upper surface of the walls of the slots constitute a flat surface, in the sense of the term defined above, which is substantially free of deviations from the flat except for the slots themselves.
  • the distribution of the slots of emission and exhaustion establish between two adjacent slots of emission a flat area extending across the line of motion of the sheet, free of apertures, above which the gases form a cushion at constant, static pressure. There are thus established along the path of the moving sheet a series of transverselyextending kinetic, pneumatic zones alternating with static pneumatic zones of support. The gas emitted by each of the two slots of emission, after establishing the zone of static pressure flows toward the nearest slot of evacuation.
  • the supporting surface thus formed is regular and progressively corrects the defects of the sheet, the different zones playing different corrective roles. It is advantageous that the part of the surface occupied by the slots should not substantially exceed 10 percent of the whole.
  • the slots of emission should offer a substantial obstruction and loss of head to the passage of the gas in order that thegas, despite the weight of the sheet, adopt a laminar flow as it issues from the slots.
  • an advantage of the invention arises from establishing the loss of head by introducing a grill or wire mesh tightly between the two walls. The introduction of this choke makes it unnecessary to machine the surfaces of the slots of emission accurately, Furthermore, this structure guarantees the maintenance of proper spacing of the lips of the slots throughout their length.
  • the width of the slots of emission are preferably between 0.4 and 0.7 mm. and ordinarily need not be greater than 1 mm.
  • the slots of evacuation offer only a negligible obstruction to free flow so that the whole of the gaseous cushion which sustains the gas is under a mean pressure which is highly uniform and which is only slightly inferior to the pressure of the gas at the discharge lip of the slot of emission. This is easily accomplished by giving the discharge slots a width of possibly 2 mm.
  • the gaseous cushion thus formed is very thin, on the order of 0. l 5 mm. or even less, but of great rigidity so that the sheet of glass is compelled to shape itself with great exactitude to the surface of reference constituted by the horizontal walls between the slots.
  • the slots should extend fully across the sheet, but the zone of the surface between two slots of emission may be reduced to improve the flow toward the outlet slots, which has shown to be advantageous for the, correction of small irregularities'in the glass sheet.
  • the sheet when the sheet has hardened it is of advantage to enlarge the distance between adjacent slots of emission inorder that the zones of static pressure represent an increased proportion of the total area, which may exceed 60 percent of the total surface of the gaseous cushion, the optimum spacing being a function of the conditions existing at a particular location. This spacing is the greater as the material is stiffer, as the speed of the sheet is greater, and as its moment of inertia is the greater; and vice versa.
  • the slots may be rectilinear, sinuous or broken but it is preferable, especially when the sheet is soft, to use straight line, parallel slots perpendicular to the line of motion of the sheet. In this way all the points of the lower surface of the glass along one transverse line are treated simultaneously and uniformly by gas flowing out of a single slot. This prevents the creation of longitudinal zones in the glass which would otherwise tend to be differently treated and introduce correlative deformations of the sheet, and it contributes largely to reduce and remove defects of planeity. Furthermore, rectilinear, parallel slots are more easily made than others. The slots are readily made by spacing vertical walls a selected distance across the line of motion of the sheet. These walls extend into pressure chambers containing gas under constant pressure.
  • the chambers are supplied with gas at superatmospheric presthe blades of gas issuing from the slots of emission.
  • the relatively large loss of head suffered by the gas passing through the choked slots assures a constant flow even when the sheet does not fully cover the blades of gas, the excess gas used thus becoming trivial.
  • the lateral flow of gas away from the edges of the sheet above the surface of the pressure chamber is very small and does not disturb the supporting cushion.
  • the gas leaving the sheet flows into the interior of the chambered pressure box which presents the slots of emission and exhaustion, it is advantageous to establish thermal equilibrium for the whole process, thereby limiting risks of deformation which might otherwise exist.
  • the spent gases may be entrapped, controlled, and recycled.
  • the slots of emission and the slots of evacuation are formed between juxtaposed walls transverse to the lines of motion of the material transported and in a plane perpendicular to it.
  • the slots of emission of one pair, seated between two consecutive slots of evacuation are separated by a hollow body through the interior of which fluids can be circulated which affect a heat exchange, heating or cooling, with the gases flowing through the slots and also with the supporting cushion and the material transported, in the latter case a substantial heat exchange occurring by radiation to or from the hollow body.
  • the elements separating the slots of emission from the slots of exhaustion may have hollow passages through which hot or cold fluids may pass.
  • thermal exchanges can be mild or intense, notably sufficiently intense to accomplish tempering, or of a minor sort which accomplishes merely a progressive cooling.
  • the cooling or heating fluids circulating through the hollow box between the slots may be used to establish a temperature gradient along the length of the moving material.
  • the cooling of the surface of the pressure box may be advantageously used to prevent adherence of the glass to the box should the two accidentally come in contact.
  • FIG. 1 is a vertical longitudinal section through the upstream end of a preferred form of apparatus
  • FIG. 2 is a section on the line lI-II of FIG. 1.
  • FIG. 3 is a perspective view, sectioned and cut away, illustrating the construction of the apparatus
  • FIG. 4 is a schematic vertical, sectional view including a dia gram of the pressures existing under the sheet, as established by the apparatus.
  • FIG. 5 is a vertical longitudinal section through a section of a unit of the invention.
  • FIG. 1 the gas which is to support the sheet is introduced by a conduit 1 into a pressure box 2.
  • the upper wall of the pressure box is provided with ranks of orifices 3 which are disposed throughout its area and deliver the gases to chambers 4 which are sufficiently larger than the apertures 3 to reduce the speed of the gases.
  • Each pressure chamber 4 distributes gas to two slots 5, 5a which are parallel to each other and transverse to the direction of motion of the sheet of glass 7 as shown by the arrow. These slots interpose the gaseous cushion between the moving sheet and the top of the apparatus.
  • a substantial reduction in pressure is provided by grilles or screens 6, 6a, which may be of woven refractory metal, extending the length of each slot between the walls and assuring a good discharge of the gas toward the sheet.
  • This loss of head is-substantial compared to the whole of the gaseous circuit and is calculated to establish a uniform pressure and uniform flow in all parts of the system.
  • the zone of static pressure is found at 8 in even intervals between two slots of emission 5, 5a.
  • the gas, having established stable pressure in these areas flows toward the slots of evacuation 10 which are parallel to the slots of emission and are composed by the parallel walls 10a and 10b.
  • the slots 10 open through apertures 12 into canals 11 which are connected by orifices 13 to chamber 14 which is common to all the exhaustion slots.
  • the chamber 14 may be connected to an outlet canal 15 for the recycling of gas.
  • the slots 5, 5a are separated by a hollow body or profile 16 having interior canals which are connected by conduits 18 to a source of fluid such as water, air, steam, which permits one to control the temperature of the gases flowing upward and of those in static state thereabove.
  • a source of fluid such as water, air, steam
  • FIG. 4 is a pressure diagram in which the zone 8 of static pressure is represented as having a pressure p which is substantially constant and which is substantially equal to the pressure of the gases flowing from slots 5, 5a. At the right of the exhaustion slots 10 the pressure falls to a valve p.
  • the pressure p,,,, for which the cross hatch surface s is equal to two times the cross hatch surface s is the mean pressure of the gaseous cushion which corresponds to the weight of the supported glass.
  • FIG. 5 shows an apparatus similar in its general principles to that described hereinabove but which has several advantages, especially in that it can be cast, that the number of parts to be fabricated is reduced, time and cost of assemblage are minimized, and the problem of maintaining gas tightness between the compartments of supply and return of the gas is eliminated.
  • the body 19 is cast in the foundry, includes slots 5, 6 of emission, and slots 10 of exhaustion which discharge into canals 11 connected to the air. These bodies have inclined upper sides 20, prismatic in shape, which receive hollow bodies 21 of trapezoidal section corresponding to the prismatic profile 20.
  • Posts 22 support the trapezoidal profile 21 in proper position, which is established by the grilles or wire mesh 6 which line the inclined walls of elements 11.
  • the tops of elements 11, 21 conform to the same plane whether it be flat or curved.
  • the gaseous cushion is plane and horizontal, but it can be inclined to the horizontal either longitudinally or transversely.
  • the upper surface of the box which generates the gaseous cushion may be arched either in the direction of motion of the sheet or transversely, for instance in the case where it is desired to support a bent sheet.
  • One may also form the box flat at its extremity, for instance upstream, and go at a progressively increasing arch toward the downstream end, thereby forming a bent sheet progressively from an initially planar sheet.
  • the advantages of the invention are in the accomplishment of the objects hereinbefore stated, and also in supporting the sheet more uniformly, with fewer disturbances, in correcting imperfections in the surface of the sheet, in giving it a superior finish, and in improving the uniformity of treatment of the sheet from side to side.
  • a pressure box having a flat upper surface over which the sheet material moves in said direction, there being a first multiplicity of slots for the emission of air, in and through said surface, and a second multiplicity of slots in and through said surface, for the exhaustion of air emerging from said first multiplicity of slots, all said slots being parallel and extending continuously substantially the full width of said ribbon, there being a pair of slots of emission between each consecutive two slots of exhaustion, the area occupied by the slots being not substantially more than percent of the whole upper surface, and conduit means connected with said box for supplying air under pressure to all said slots of emission, and for exhausting air from said slots of exhaustion.
