Definitions

  • This invention relates to apparatus for sealing chambers at points where web materials enter or leave the same.
  • any thickening of the web material causes a binding and slowing of the web, and tearing results from the traction exerted by downstreamward pulling means: such thickening occurs, for instance, when two web lengths are joined in the usual fashion by a lap joint.
  • downstreamward pulling means such thickening occurs, for instance, when two web lengths are joined in the usual fashion by a lap joint.
  • devTces usually require careful adjustments for web stocks of even minor change of normal thickness, and to compensate wear: and an adjustment which places a pressure upon the web, even by driven rolls, can cause a calendering effect which changes the surface characteristics and hence modifies the behavior during the treatment in the chamber: this is true of both coated paper stocks and stocks in which specific surface patterns are to be retained.
  • rollers whose axes are staggered at the sides of the web and which have surfaces so disposed as to permit the web, with the variations of thickness, to pass between the rollers of a pair without pinching, and with the surfaces also making contact with the two surfaces of the web so that the leakage is being restricted by the presence of the web itself.
  • An object of this invention is to provide a seal for admission or withdrawal of a web from a treating chamber, in which the web moves between the staggered rollers of a pair and in contact with both rollers but without being pinched or squeezed therebetween.
  • Another object is the provision of a seal of such type, which is competent to restrict leakage of atmospheric gases inward toward a vacuum chamber, with pressure reductions of 10:1 or greater, between the inlet and outlet of a single unit structure.
  • a further object is the provision of a seal which can be easily opened for threading of a web of material therethrough, and easily closed again to sealed condition.
  • Fig. 1 is a conventionalized showing, partly in upright section, of a vacuum deposition apparatus having a treating chamber to which a web is fed and withdrawn through seals according to this invention, three sealing units being provided at the inlet and outlet points.
  • Fig. 2 is an upright longitudinal sectional view, substantially on line 22 of Fig. 3, showing the arrangement of parts in a single unit.
  • Fig. 3 is an upright transverse sectional view, substantially on line 33 of Fig. 2, showing the driving devices and the parts provided for opening the unit for threading the web.
  • Fig. 4 is an upright section, substantially on line 44 of Fig. 3, showing a drive system.
  • Fig. 5 is a fragmentary detail section substantially on 1 line 5-5 of Fig. 2.
  • Fig. 6 is an upright section through another illustrative form of the invention.
  • Figs. 7a and 7b together comprise an upright section, on a larger scale, through the combined inlet and outlet structure of Fig. 6.
  • Fig. 8 is a fragmentary conventionalized diagram, on a larger scale, showing the path of a web over rollers.
  • a web of paper W is provided on a supply roll 10, from which it is withdrawn into the inlet 11 of a first inlet seal unit 12, and thence moves in succession through the second inlet seal unit 13 and the third inlet seal unit 14, and then enters the vacuum deposition chamber 15.
  • the coated web CW leaves chamber 15 and enters a first outlet seal unit 16, and then passes in turn through the second and third
  • the treating chamber is shown as having an inlet guide roll 21 over which the webmoves and by which it is guided downwardly to the surface of a large coating roll 22.
  • the web moves from the coating roll 22, a turning roll 23, beneath a second coating roll 24, over a second turning roll 25, beneath a third coating roll 26, over a third turning roll 27, and thence into the first outlet unit 16.
  • This employment of three coating rolls is illustrative of presentation of a surface of the web for acceptance of vaporized metal, such as aluminum, in the treating chamber 15.
  • the coating rolls can be cooled by outlet seal units 17, 18 and is rewound on a take-up reel means known to those skilled in the art; preferably all rolls are positively driven.
  • Vaporizer elements :E are supported on and receive electrical current from these bus bars: such elements may be of the types shown in my patents, being resistively heated by the current to a temperature above the evaporation point of the deposit material at the low pressure prevailing in the chamber 15.
  • the deposit material may be provided as a filament or wire on reels 32, from which it is drawn by the driven feed rolls 33, and thus delivered into contact with the tops of the heated elements E.
  • the material melts, spreads, and is vaporized to form anatmosphere withinthe chamber 15; and con- .denses .upon the surface of the web W as the latter is supported opposite the elements E by the coating rolls.
  • the sealing units 12, 13, 14, 16, 17, 18 may be made identical: and one illustrative unit is shown in Figs. 2 and 3.

  • the bottom 40 has a'number of transverse ribs 45, above each of which is journaled a lower roller 46, of which six are shownin the illustration.
  • These rollers may have polished steel or .chrome-plated surfaces, and have shaft extensions 47, 48
  • each extension 48 has gear 52 secured thereto for driving the same.
  • Sheets 53 of a resilient inert material of low -frictional resistance are bent to an L-shape and placed -inithe.
  • the bottom 40 has a flanged hollow extension 57 to whichsuction means may be connected, noting that this "60 has a number of transverse ribs 65, below each of which is journaled an upper roller 66, the number of rollers 66 being illustratively the same as the number of rollers 46 so that the rollers are present in pairs.
  • Each roller 66 has its axis offset or displaced, upstreamward in the illustrated form, relative to the transverse plane through the respective lower roller 46, and is supported out of contact therewith but having its lower generatrix below the level of the upper generatrix of the respective roller 46, so that the web is turned through small arcs in its movement between the rollers of a pair and in its movement toward the next pair.
  • the rollers 66 may be of polished steel or chromium-plated, and have shaft extensions 67, 68 at their ends. These extensions 67, 68 turn in bearings 69, 70, corresponding to the mounting of the rollers 46, and are provided with end sealing plates 71 and gears 72. Sheets 73, corresponding to sheets 53, are
  • the end walls 41, 61 and 42, 62 are spaced from one another to provide slits 80, 81 for the entrance and exit of the web W; these slits being presented for movement of the web without major contact therewith, noting that external guide rolls 82, 83 (.Fig. 1) may be provided to regularize the position of the web W at entering and web CW at leaving the assembly.
  • the bottom and top walls 40, 60 are extended laterally and connected to side sealing walls 84, 85 which overlap one another (Fig. 5).
  • the walls 85 have grooves 86 for receiving packings 87 correspondingto the so-called O ring; and screws 88 are employed for drawing the walls 84, 85 tightly upon the packings 87.
  • the wall 85 is shown as having a shelf 89 for receiving spacing means 90, such as shims, for engagement by the lower edge of wall 84 and thereby limiting the relative downward movement of the upper structure. This limitation on the relative movement of the structures determines the relative positions of the rollers 46, 66 forming part of the respective structures, and of the vertical dimension of the slits 80, 81 in the illustrative form.
  • one of the shaft extensions 48 is shown as having a portion 91 passing through a packing gland 92 in the lower or fixed wall 85: whereby a power source external to the evacuated structures can be employed for moving the rollers 46, 66.
  • the gears 52, 72 of each pair of rollers 46, 66 are shown as meshing in the operative position of the parts, and idlers 93 are present for transferring motion between successive gears 52.
  • the operation of threading or preparing the structure for operation is simple.
  • the bolts 88 of the units are released, and the upper structures raised; therewith separating gears 72 from gears 52 in each, and leaving the .lower rollers'46 exposed.
  • the chamber 15 has a removable top 15a with a sealing gasket 15b and clamping bolts this top is also removed.
  • the outlet sealing units areopened like the inlet units.
  • the web W is drawn from the:roll 10, passed over the rollers 46 of the inlet units,;threaded over and under the turning and coating rolls in chamber 15, and then passed over the rollers 46 of :the outlet-units.
  • the end walls 42 have flanges'projecting beyond the bottom wall 40 and the side walls, and bolts 94 can be passed through these flanges and through the corresponding flanges of the end wall 41 of another'unit, with a sealing gasket 35 between them.
  • 'Supports96 can also be held by such bolts, to mount the unit or group-of units from a frame on the floor as a rigid structure, with the inner stages 14, 16 likewise boltedand sea-ledrelative to the walls of chamber 15.
  • the firstinlet and third outlet units 12, 18 are connected at their extensions 57 to conduits 100 which are under evacuation by a rotary mechanical pump: in practice, it was found that, with the outlet 81 sealed, such a pump could reduce the pressure in space 5 8 to 68 millimeters even in the absence of a web.
  • the inlet slit was reduced so that the pressure in the chamber between the end walls 41, 61 and the rollers 46, 66 was about 34 millimeters absolute, the pressure in chamber 58 was reduced quickly to 208 microns by a 250 liters per second oil sealed pump.
  • the second inlet and outlet units 13, 17 are connected at their extensions 57 to conduits 101 which are under evacuation by a low pressure pump of oil seal type: in practice when units 12 and 13 were thus operated, with the outlet slit 81 of unit 13 sealed, a pressure in the chamber 58 of unit 13 was reduced to 100 microns.
  • the third inlet and first outlet units 14, 16 were closed off and not connected to pumps, so that the pressures in their chambers 58 closely followed the pressure in the treating chamber 15 which illustratively is evacuated by a diffusion pump connected to the exhaust connection 102, to a pressure of, say 0.1 micron.
  • the chamber 58, of each unit, is located at the end thereof nearest the treating chamber 15.
  • the slits 80, 81 of the units were adjusted to between 0.008 and 0.012 inch: it being found that the operation was essentially the same within this range.
  • the spacing between adjacent generatrices of the pairs of rollers was adjusted to about 0.007 inch, corresponding to a lap joint of two paper thicknesses and a glue joint 0.001 inch thick. In general, the spacing should be from 2 to 4 times the thickness of paper material, and corresponding allowances for other materials, based on irregularities in thickness thereof and the known thicknesses at joints.
  • the rollers 46, 66 had diameters of about one inch, and were spaced one and a half inches apart in both upper and lower pans.
  • Each upper roller 66 had its axis spaced inch upstreamward from the upright plane of the corresponding lower roller 46.
  • the rotary mechanical evacuation pumping equipment for the first inlet and third outlet units 1'2, 18 drew about 30 liters of free air per second or 60 cubic feet per minute.
  • the other stages or units 13, 17 and 14, 16 were connected as above. It was found that under such conditions, the minor leakages by having the paper width less than the spacing of the plates 51, 71 did not affect the operation; when the paper was 4 inch narrower at each side, i.e. with an equivalent effective slit /2 inch long, the units 12, 18 were reduced to and held at about 25 millimeters absolute pressure at their connections 57; and second stages or units 13, 17 were reduced to 68 microns.
  • the leak effects in the units 14, 16 were negligible, being less than leakages of the chamber 15 itself.
  • the outer stages were reduced to and held at 48 millimeters pressure, the middle stages at 50 to 128 microns, and the inner stages were essentially at the intended pressure of the chamber 15.
  • the wiper plates 53, 73 were omitted, but the pan walls were located as close to the roller surfaces as possible without contact.
  • the gaps between rollers was 0.009 inch, which was found effective with web thicknesses of 0.004 inch, to permit a splice to pass.
  • the inlet end was sealed except for two ports: a manometer was connected at one port, and a needle valve at the other. The outlet end was connected to an evacuating pump.
  • Empirical equations can be established, as to the total amount of leakage through the unit as a function of the width of the gaps, etc.
  • G--Widths of the gap between rollers not covered by the web L -Total leakage through 1st stage. L --Total leakage through 2nd stage. L Leakage through the gap not covered by paper. L -Remainder of the leakage. W-Width of the unit, i.e. width of the rollers.
  • the amount of leakage is expressed in millimeter litres per second in the first stage and in micron litres per second in the second and third stages. If the leakage and the pumping speed are known at each stage, the prevailing pressure can be obtained by dividing the leakage with the pumping speed. Alternatively, if the leakage is known and the desired pressure is chosen, the leakage divided by this pressure will give the pumping speed necessary for obtaining the selected pressure.
  • the pressure between the exits of the first and second stages is reduced by a factor of 200 (from 35 mm. to 177 microns) with a pumping speed of 500 l./second.
  • P the measured P and 24 microns with a pumping speed of 240 l./secoud, thus reduced again by a factor of 200.
  • P will be only about 0.9 micron and the leakage rate 216 micron liters per second (abbreviated, l./sec.).

  • only about 12% of the pumping speed will be used to take care of the leakage through the sealing unit. This is considerably less than needed to take care of the entrapped air in a master roll-of paper or plastic film loaded in a non-continuous machine.
  • the fresh web W is fed from a supply roller over a guide roller 111 and into the sealing structure by a slit 112. After passing through the sealing structure, the web W is guided downwardly through an opening forming communication between the sealing structure and the interior of the treating chamber, and past a turning roll 114 and thence onto the surface of a large cooled drum in the treating chamber 115.
  • This drum 116 is driven and the web is coated by condensation of vapor coming from the vaporizer elements E.
  • the coated web leaves the drum near its top and passes the turning roll 117 and re-enters the sealing structure. From the sealing structure the coated web CW passes through a slit 113, a guide roll 118 and is re-wound on a take-up reel 119.
