ABSTRACT:
A seal device having a pair of rubber seal rolls arranged in pressed contact with each other at a cloth material passing port of a drum body of a high pressure steamer adapted for hygro-thermic treatment of textile products such as a cloth material. Seal plates which are formed with a flexible and elastic metal or synthetic resin sheet and upper or lower sides of which are secured to edge portions of the cloth material passing port disposed in parallel with the pair of seal rubber rolls while the other sides are in pressed contact with the seal rubber rolls. An air chamber formed in a triangular cross-sectional shape connects a pressed contact point between the rubber seal rolls respectively to contact points between the seal plates and the seal rubber rolls, and air pressure is supplied to the air chamber through an air supply passage. A pair of correcting air jet pipes are spaced across the cloth material and arranged to blow air to both sides of the cloth material to correct its posture for preventing it from being wound on the surface of the seal rubber rolls after it has passed these rolls. A passage is provided for expelling to the outside a surplus portion of the air supplied to the air chamber to prevent it from coming into the drum body.
