Definitions

  • ABSTRACT A roller-lock is used as a sealing system for the inlet and outlet of material webs into or out of autoclaves and consists of a series of individual pressure chambers which are separated or defined by pairs of rollers whereby, the material passing from the atmosphere into the the pressure chamber of the autoclave moves through several staged pressure chambers having increasing pressure therein. When the material passes out of the autoclave it moves through the same chambers in an opposite direction to be subjected to staged decreasing pressure as it passes out of the sealing systern.
  • continuous pressure steamers for the high-pressure/saturated steam treatment of web-shaped textiles can also be used for pressures of more than 3 bars (approximately 2 atmospheres gauge), if a roller-lock is used as the sealing system for the material inlet and outlet into or out of autoclaves.
  • this roller lock consists of a series of individual pressure chambers, whereby in the case of the material inlet from the outer atmospheric pressure to the working pressure in the autoclave pressure stages with increasing pressure are arranged while in the case of the material outlet in the opposite transport direction pressure stages with falling pressure are arranged behind one another.
  • roller-lock characterized by the fact that the pressure chambers consist of pairs of rollers of various hardness and in each case are spaced to define squeezing slit along the roller width in pairs on the cylindrical jacket thereof, whereby, when the direction of rotation remains the same, the roller pairs concerned are means for the material inlet as well as also for the material outlet.
  • the transport of the material web is directed between hard rollers and rollers coated with an elastic covering.
  • roller-lock according to the invention serves at the same time for the roller inlet and outlet. That means a considerable simplification of the pressure steamer, increase of operating safety and reduction of the susceptibility to interruption.
  • the sealing is carried out not in the fiber material, as with lips, pressure tube or membrane seals of the prior art but only on the rollers, whereby an impairment of the material surface is eliminated and the regularity of the absorption of the dye liquor is as sured (i.e. no slide tracks are formed).
  • the pair of rollers consists of an elastically mounted smooth metal roller 3 and of a soft roller 4 provided with an elastic covering 9, for example of rubber or soft plastic.
  • the metal rollers (hard rollers) are embedded for the sealing against the atmospheric pressure in plastic cups or pressure tubes 5, the pressing power of which may be regulated against the rollers by applying pneumatic or hydraulic pressure via corresponding feed pipes 7.
  • the material comes into the first pressure stage chamber 6, which is isolated from the outer atmospheric pressure through the squeezing between the pair of roller pairs 3, 4 on the cylinder circumference on the one side.
  • the front ends, axles and bearings are sealed by known elastic sealing elements with adjustable pneumatic or hydraulic pressure.
  • the pressure (against the atmospheric pressure) in the first pressure stage chamber 6 is only higher by a part amount of the working pressure provided for, for example, on average by 0.5 to 1 bars. This small pressure difference makes it possible to keep low also the pressures applied of the elastic pressure tubes and the roller pair 3/4.
  • the pressure tubes or plastic cups 5 themselves are provided with a sliding covering 8 adjacent the roller 3 so that the friction resistance, the seal and the frictional heat are then likewise low, and the dye liquor is not pressed out at the squeezing slit.
  • Pressure stage chambers 6 opposite one another should be expediently under the same pressure.
  • roller-lock is used for the material inlet as also for the material outlet without it being necessary to undertake alterations.
  • the material runs through the pressure stage chambers at the outlet and the roller pairs in the opposite direction as with the material widths running in whereby the pressure is now released by stages.
  • a sealing system providing a pressure seal inlet and outlet for textile fabric webs between the interior of a high pressure chamber on which the system is mounted and a lower pressure zone such as the atmosphere, said system comprising a housing having first and second open end portions and at least one pair of opposed oppositely extending walls, said first open end portion communicating with the interior of said container and said second open end portion providing an inlet and an outlet for the webs supplied to the pressure chamber; and a plurality of sets of rollers mounted in said housing in sealing relation between said pair of opposed walls, and defining a plurality of separate pressure chambers in the housing through which the webs pass on their way into and out of said high pressure chamber; said sets of rollers including a first set of rollers mounted in said housing with their axis of rotation parallel and in spaced alignment with each other between said first and second ends of said housing; each of the rollers in said first set being covered by an elastic material; and a second set of hard rollers comprising a plurality of pairs of rollers respectively associated with at least one of said elastic rollers; the
  • said biasing means comprises generally semicylindrical inflated sleeves mounted in said housing adjacent said hard rollers on the sides thereof opposite the nips formed between the hard rollers and the elastic rollers whereby the biasing of said hard rollers into engagement with the elastic covered rollers is regulated by the inflated sleeves so that the nips between the rollers will be substantially pressure-tight.
  • a sealing system as defined in claim 4 including reducing valve means for regulating the pressure in the pressure chambers in said housing between the rollers.
  • a sealing device for sealing the common inlet and outlet opening of a high pressure chamber in which textile fabric webs are treated; said device comprising a housing mounted on said chamber in communication therewith and having a series of staged pressure chambers formed therein for providing a graduated pressure drop between one end of the housing adjacent the high pressure chamber and the opposite end of the housing; said housing having a pair of end walls, and said staged pressure chambers being formed between said end walls and a plurality of rollers rotatably mounted therebetween in sealing relation and in contact with each other to form gas and pressure tight nips therebetween to define said staged chambers; said rollers including a series of groups of rollers each of which includes at least one pair of laterally spaced hard rollers, and a roller covered with an elastic material positioned between the hard rollers in contact therewith on opposite sides thereby to form pressure tight nips on opposite sides of the elastic covered rollers for respectively engaging fabric moving into and out of said high pressure chamber and for sealing adjacent staged pressure chambers
