ABSTRACT:
In a side seal mechanism of a high pressure steamer consisting of a pair of seal rubber rolls provided respectively above the cloth inlet and outlet, a seal block to support the seal rubber rolls and a side seal plate, an automatic pressure control device of the side seal plate comprising providing a side seal plate which is supported by means of a seal block so as freely slidable in the axial direction of the seal rubber rolls, a pushing-pressure control screw which is screwed to a support member attached en bloc to the seal block so as movable in the axial direction of the seal rubber rolls, a pressure-push plate movable in the axial direction of the seal rubber rolls in operating the pushing-pressure control screw, and a cushion rubber body interposed between the pressure-push plate and the side seal plate. The pushing-pressure against the side seal plate due to the thermal expansion of the seal rubber rolls can automatically and satisfactorily be absorbed with the use of a cushion rubber body.
