  • a further disadvantage is that it is also very difiicult for certain of these means, devices, arrangements and the like to be dismantled or replaced, and that those parts of the installation which form a unit, for example, a long boiler, can only be transported with special auxiliary devices and also with considerable loss of time.
  • the present invention permits all these disadvantages to be avoided in a simple manner; at the same time, a number of very important additional advantages are obtained.
  • the installation provided by the present invention for continuously treating (for example impregnating or vapour-treating) strip-like material under vacuum is built up of components adapted to be assembled in sections, each of the components being associated with a predetermined treatment or stage of the treatment and the components being adapted to be coupled to one another with sealing.
  • the individual components of the installation each comprise, for example, an independent treatment group which may consist of vacuum pumps and pipe lines, valves, cooling assemblies, transformers, switches, fuses, impregnating rollers, etc. All these parts together form an independent unit and a self-contained operating group. It is only necessary, for example, for the electric mains and the cooling water supply to be connected for setting the installation in operation.

It is only necessary, for example, for the electric mains and the cooling water supply to be connected for setting the installation in operation.
  • the individual components of the installations are mounted, for example, on wheels running on rails, whereby it is possible in certain cases for the components of the installation to be taken apart and replaced-conveniently and simply.
  • the separate components of the installation for example, the separate sections of a vacuum boiler, to be mounted on their own travelling frames or carriages.
  • the couplings connecting the components to one another are to be so constructed thatthe components are also capable of being adjusted relatively to one another when they are coupled, this being useful or necessary, for example, when it is a question of modifications or adaptations in the guiding of the material being conveyed.
  • the means for adjustment purposes may, for example, be provided spaced apart arcuately by on the casings of the components.
  • couplings are advantageously incorporated in the pipe lines between the vacuum pumps arranged in a fixed position after the installation, especially for the convenient separation and replacement of the components of the installation, perhaps when threading the strip to be vapour-treated through the narrow slots of the sealing means between the components.
  • the vacuum pipe is provided at this separation point with two plates, one of which is surface-ground, while the other comprises a dove-tailed groove with a rubber ring. This permits a certain relative displacement of the pipes or tubes at the junction, which is advantageously so arranged that when the components are brought together, the two plates are automatically urged one against the other.
  • the packings between the components are advantageously provided externally on the walls, for example, of the boiler sections.
  • Each component of the installation is preferably pro vided at least at one end with a rigidly fitted ring or the like which is, for example, welded around the said end and projects beyond the latter, the ring embracing the other component which is coupled to this point or being embraced by the other component, and a resilient packing ring'bearing on two components to be sealed oil relatively to one another is provided in at least one encircling groove of the ring and/ or of the bearing part forming the counterpart of the ring.
  • the packing ring may be a tube, adapted to be expanded by means of air, gas, oil or the like in such manner that the ring bears tightly and firmly against those parts of the installation which are to be sealed off.
  • the packing ring for example, a tube
  • the groove may have a substantially dovetailed cross-section for this purpose.
  • the tube may also be secured by split rings or by adhesives.
  • the pins are surrounded at the sealing position by hollow (and perhaps inflatable) packing rings, which are Vulcanised, for example, on pins and in turn are surrounded, for example, by projections of that wall (for example, of a vacuum boiler) provided with openings for the lead-ins.
  • the means, devices, arrangements and the like to treating, for example, strip-like material are advantageously arranged separately or in groups on supports independent of the housing of the corresponding component, which supports may comprise frames consisting of sectional members or the like, which are passed through the wall of the housing of the corresponding components of the installation while being sealed off against vacuum or a positive pressure.
  • the correspond- Those parts of .the installation for example, vacuum chambers, which are at the delivery end considered in the direction of the process are expediently supplied by a vacuum pump, preferably a steam-jet pump, which is economic in the low pressure range, while the common main vacuum pump is .connected to the chamber at the inlet end.
  • a throttle valve or an overflow valve is advantageously disposedbetween these two chambers, for example, in the partition.
  • the chamber with the less effective vacuum is connected to the initial vacuum side of the steam-jet pump by way of a separate pipe line adapted to be closed by means of a throttle valve.
  • the valve is-closed and the initial vacuum side of this pump, parallel to the other component at the inlet end, is connected to the common main vacuum pump.
  • sealing means for the lead-in for the material between the components for example, two vacuum chambers
  • two parallel plates the spacing of which is small in relation to the free path length of the gas molecules, it perhaps being necessary to utilise the laws of molecular flow.
  • the flow resistance of this device may readily be so great that the highest vacua are maintained even with very great pressure differences between the two chambers, without the web or the like conducted therethrough being impeded or impaired in any way.
  • sealing plates it is also possible to use two endless travelling belts or bands forming a slot-like passage, or only one such belt or band and a rotating roller engaged by the latter over a relatively large part of its circumference; the belts and the roller accompany the material at a certain'speed while it travels through this slot-like sealing passage, which is in effect also moving.
  • the material is thus subjected to very gentle treatment, because relative movements between the material and the belt or roller do not occur.
  • the sealing effect is very good, -because the belts and roller completely enclose the strip-like material over a relatively long distance.
  • the belts and roller may at the same time serve as driving means.
  • supplementary sealing means for example, bars covered with fabric, which are arranged transversely of the direction of travel and rub on the belts and rollers.
  • Such bars may in addition serve as separating devices, for example, for dust, and also as a brake it they are adjustable.
  • the travelling belts, rollers or the like particularly have the advantage that in practice there is 'no deleterious eifect on the travelling material while maintaining a good sealing action, because no relative movement occurs between this material and the travelling belt or belts and roller.
  • these sealing means are in particular also very suitable if a material formed with apertures, for example, gauze-like material, is to be moved therethrough.
  • the individual threads or the like of the gauze which have a tendency to cause creeping paths along them and thus an undesirable transfer of air for one chamber to the other, are satisfactorily enclosed by the two travelling belts or by one belt and a roller accompanied by this belt over a large part of its circumference, because the belts are usually capable of being made sufiiciently long or the diameter of the roller sufiiciently large.
  • the arrangement en- -sures a very good sealing action with a very gentle treatment when sensitive material, such as perforated foils having a thickness of for example, only 0.1 mm. are to "be passed through, or when it is a question of very large pressure differences between the chambers.

  • the holes forming the viewing passages provide a practically unimpaired vision of the vapour-treating chamber in accordance with the optical principle which is known per se.
  • the holes are at the same time so formed, arranged and directed that the observer can accurately inspect the entire vapour treating chamber, preferably from diflerent points.
  • the vapour-treating chamber is advantageously arranged completely enclosed in one of the independent components of the installation, perhaps as a single treatment space filling this component, and is preferably supplied by its own vacuum pump; in this case, the strip-like material to be vapour-treated advantageously itself forms the upper limit of the treatment space.
  • the winding by means of supporting rollers is particularly suitable for materials which satisfactorily withstand the great pressure which obtains between the coil of strip material which is always increasing in weightand the rollers supporting it by hearing on the circumference.
  • the rolling method using a winding rod is particularly suitable in order to reel more sensitive and perhaps very soft or brittle material.

  • Each section of the installation is mounted on a travelling frame or carriage 9, 10, 11 and 12, respectively; the sections are adapted to be moved axially so that the strip-like material may be conveniently passed through from the chamber to chamber through narrow sealing slots.

  • the sealing belt 20 is advantageously tensioned by the tension spring 25 to such a high degree that it not only urges the material 13 firmly against the roller 15 but also causes the sealing means completely to absorb any excess pressure between the chamber 19 and a space 31 which may also be a chamber.
  • the complete sealing arrangement may also be completely arranged in one of the chambers, for example, in the chamber at higher pressure.
  • casings 32 and 33 of the sections 1 and 2 respectively are adjustably coupled to one another by a ring 35 welded to the casings 32 and 34.
  • the ring 35 projects from an end of the casing 32 towards the casing 33 and surrounds the latter casing with a small clearance 36; it has an internal peripheral groove 37 in which is arranged a hollow packing ring 38, which ring may be so expanded, for example, by compressed air or oil under pressure, that it completely and reliably seals off the two sections while at the same time maintaining some degree of flexibility between them.
  • a wall 39 for example, the Wall :of the boiler section has a connection 41 which is fixed by a weld seam 40 and has at one end a collar 42 with an internal peripheral groove 43 surrounding a hollow, inflatable packing ring 44 which in turn closely surrounds a collar 45 of a copper pin 46 of an electric conductor; the pin 46 can for example, be hollow and adapted to be cooled by water.
  • Figures 5 and 6 shows a construction in which a disc 47 has radially extending rows 48 and 49 of apertures 50, 51, 52. Radial partitions 53 and 54 are arranged between the rows and form individual compartments and which are at the same time fitted on another disc 55 and secure the discs rigidly to one another to form a structural unit.
  • the discs and the partitions are driven by means of a common hub 56 and a shaft 57 so that the discs 47 and 55 run synchronously.
  • the drive means may be of any desired type, for example, an electric motor.
  • the disc 55 faces the pane 58 of a control window and is made of a transparent material, for example, glass and the other disc 47 faces a vapour-treating chamber 59.
  • the chamber 59 is enclosed by a housing, of which a part is illustrated at 60.
  • the housing is provided with a tube section 61 and the window pane 58 is fixed at the free end of the section 61 in a sealed manner.
  • An opening, for example, 51, in the disc 47 corresponds to an opening 62 in the disc 55; both openings are in alignment with one another and are parallel to the axis of rotation 63.
  • a metal particle passing through the opening 51 of the disc 47 in the direction of the arrow 64 does not pas-s through the aligned opening in the other disc 55 owing to the continued synchronous rotation of the latter, for example, in the direction of the arrow 65, which takes place as the particle is travelling forward, but this particle instead impinges, for example, at 66, on the solid wall 7 of the disc 55; at this time, the opening 62 has reached the position -67 shown in dotted lines.
  • the apertures, the mutual spacing and the speed of rotation of the discs are accordingly adapted to the speed of travel of the particles of metal vapour.
  • an electric motor 68 or the like drives a bevel gear '72 through an infinitely variable gear 69 and a spur wheel gearing 70 as well as an additional infinitely variable gear 71, the bevel gear 72 rotating the spur gear 7 through another bevel gear 73.
  • Supporting rollers 75 and vs are driven by the spur gear 74 through additional spur gears arranged coaxially with the latter.
  • a belt pulley or the like driving, a belt pulley on the shaft 78 by means of a belt 77.
  • Chain- Wheels and chains or like transmission systems may be used instead of belt pulleys and belts.
  • a winding bar 79 Arranged on the shaft 78 is a winding bar 79 by means of which the coil 80 of strip material is set in rotation. After the strip or web 81 of, for example, paper has passed through a sealing means (not shown) between the preceding chamber of the installation and that chamber of the installation receiving the winding device, the web travels over guide rollers 82, 83 and 84 and on to a roll 80.
  • a feeler roller 85 or the like loaded by its own weight runs on the roll 80, and is carried by an arm 86 which is pivotally mounted at 87 and which (in a manner illustrated in purely diagrammatic form) operates through a control line 88 on an adjustment means 89 of the infinitely variable gear 71.
  • the infinitely variable gear 71 is so influenced by means of the pivoted feeler roller 85 (acting through the adjustment means 89) which is influenced by the diameter of the roll 80 that the winding speed for the web 81, which speed positively increases with increasing diameter of the roll 80, is maintained by the infinitely variable gear 71 at the prescribed value, for example, is kept constant, that is to say, the gear 71 correspondingly reduces the speed imparted to it by the driving motor ,68 through the two gears 69 and 70, so that the supporting roller 76 driving the winding bar '79 is given a driving speed which is lower in proportion as the diameter of the roll increases.
  • Figure 8 which figure illustrates a winding of the material on to supporting rollers accordingto the invention
  • Figure 7 all the elements of Figure 7 are provided with the same reference numerals.
  • the difference as compared with the other winding system is that the supporting rollers 75 and 76 drive the roll of strip 80 constantly winding on to the rollers at the periphery of the roll of strip material.
  • the strip travels through a heating chamber 91 which is heated by electric heater wires 92, infra red radiators or the like, then through a slot 93 of a 96 which is sealed in relation to the container holding the liquid @by -means of a spring-loaded slide 97;
