ABSTRACT:
Sealing device for the continuous inlet and outlet of textile material in the form of endless ropes into and from a pressure-tight container under high temperature conditions, consisting of a number of locks of graduated pressure, which are positioned one behind the other in the transport direction of the rope, and characterized in that each pressure lock is a sealing element made of elastic material in the form of the common shell of two frusta of straight circular cones of different height, which abut on each other axially with their top faces, and which face, in the direction toward the open base of the lower frustum the room under higher pressure, and whose internal surface is lined with a smooth layer and the inner diameter of the sealing element approximately corresponds to the diameter of the cylindrically shaped textile rope, so as to be tightly pressed from all sides onto the textile material under the action of the higher internal pressure exerted in the pressure container on the outer shell of the frusta.
