Definitions

  • ABSTRACT A sealing means for a container which permits the entrance or exit of a web of material to be treated inside the container.
  • Three cylindrical rolls are rotatably mounted in series in the opening of the container and three endless sealing strips of resilient material are pressed against the three rollers.
  • the sealing strips each have two straight portions, each arranged parallel to the axis of the roll.
  • Each sealing strip also has two circular portions near each end of its roll which join the ends of the straight portions.
  • the web material is passed between the sealing strips and the surface of each of the rolls.
  • a sealing apparatus of the type initially specified in which several hoods define the wall or portions of a wall of an intermediate chamber disposed between the treatment container and the atmospheric environment.
  • two hoods can be arranged mirror-symmetrical relative to a roll center plane in defining the intermediate chamber in such a way that the two hoods define the charge and discharge opening of the intermediate chamber.
  • the intermediate chamber can be pressurized with a fluid or it can be evacuated and its contents heated or cooled.
  • the intermediate chamber brings about a pressure step-down between the gas or vapor container and atmosphere, so that on the one hand an essential sealing of the treatment container is provided, on the other hand there is the possibility of subjecting the product web to a differentiated further treatment in its course from the treatment container to the atmospheric environment.
  • each of the intermediate chambers can be evacuated or cooled, pressuredifferentiated or pressurized with different fluids in a manner different from the adjacent chambers.
  • FIG. 1 is a cross sectional view of one of the sealing means taken along a transverse plane.
  • FIG. 2 is a partial side view of one of the sealing means showing one of the end portions.
  • FIG. 3 is a cross sectional view of three sealing means joined in series between the container and the atmosphere.
  • the product web 1 passes in the direction of the arrow 2 from a gas or vapor treatment container 20 into a hood 1 1 curved in cross section, the edge 12 of which has the two straight sections 13, 14 and two arcuate side sections 15, of which in FIG. 2 only the right-hand section has been shown.
  • the shield 16 of the kidney-shaped hood 11 is interrupted at 17 along a length in such a way that the product web can be fed into the hood 11 in direction of the arrow 2 in the illustrated manner.
  • the hood edge 12 with the straight sections l3, l4 and the arcuate sections 15 have a hub-like configuration and accommodates the endless, elastic seal strip 18 which defines a closed space curve with its straight sections 18a and its arcuate sections 18b (only the right-hand one of which is disclosed in FIG. 2), said space curve extending in such a way that the endless seal strip 18 engages the pull roll 6 before the product web 1 is drawn in between the straight section 18a of the elastic seal strip 18 and the pull roll 6.
  • a similar hood 11 is provided on the side remote from the hood 11, said hood 11 having an edge 12 with a seal strip 18 and shield 16 with an opening 17'.
  • the product web 1 is drawn from the roll 6 through this hood, after it has been looped around the roll 6 between the two straight sections (the lower ones in FIG. 1) of the two seal strips 18, 18'.
  • Each of the two hoods 11, 11 is provided with a frame plate 21 21', which confine walls 22, 22' and 23, 23' as well as the roll 6, the interior of an intermediate chamber 24 relative to the treatment container 20 and the atmospheric environment disposed adjacent the hood 11' on the right-hand side in FIG. 1.
  • the space of the intermediate chamber 24 defined above and below the roll 6 as well as lateral of the hood 11, 11' can be in communication through a line 25 with a further container, by which an intermediate pressure between the pressure in the container 20 and atmosphere is produced in the intermediate chamber 24, and the intermediate chamber 24, on the other hand, can also be evacuated or its contents can be cooled or heated or can be treated in some other way.
  • the two plates 21, 21 including the walls 22, 23 and 22', 23' can define the half of the wall of the intermediate chamber 24 each by means of further walls 26, 27, so that the assembly of the intermediate chamber can readily be effected with the two hoods 11, 11'.
  • the product web 1 passes in direction of .the arrow 2 to a first hood 1 11 with a seal strip 118, in order to partially be looped around the roll 106 and passed into a second hood 21 1, which confines a further intermediate chamber 224 with its seal strip 218, the confining walls 28 and 28a as well as the seal strip 318 of a third hood 311, a second pull roll 206 being arranged in said further intermediate chamber.
  • the product web is discharged from the hood 311 into a third intermediate chamber 324, which is confined by the seal strip 318, the walls 29, 29a and 29b and the seal strip 418 of a further hood 411.
  • a third pull roll 306 is provided in the chamber 324.
  • the product web is drawn into a treatment container 31 from the hood 411 via a roll 30.
  • the chambers 124, 224, 324 are connected through conduits 125, 225, 325 with further containers so that different pressures can be produced in the intermediate chambers 124, 224, 324, different fluids can be introduced and a different evacuation or cooling can be effected.
  • Each of the chambers 124, 224, 324 is attached to its adjacent chamber by a hinge, each chamber having an arm 32 which is connected to an arm 34 of the adjacent chamber through a hinge 33.
  • the bulkheads of the adjacent chambers can be releasably connected to one another by screw connections 35.
  • each of said plural sealing compartments is connected to its adjoining compartment by means of a hinge.
  • each of the compartments is connected to a conduit through which a fluid may be applied to alter the temperature of the pull rolls and the web.
  • each of said plural compartments is connected by a conduit to a system which provides graduated pressures in steps ranging from the container pressure to the atmospheric pressure.
