Abstract
A method of and device for sealing a high pressure steamer for the continuous wet heat treatment of a cloth utilizes a steamer body provided with a seal mechanism consisting of a pair of seal rubber rolls located at the cloth inlet and the cloth outlet thereof, and includes filling a gas having a density heavier than air in a cloth passage into and out of the steamer body and providing a gas body between each of the cloth inlet and the cloth outlet and the cloth passages into the steamer body with the seal rubber rolls under the same pressure as in the steamer body. A gas having a density heavier than air to be filled in the gas bodies may be replaced with air. The leakage of high temperature and high pressure steam in the steamer body through the inlet side and outlet side seal mechanisms can completely be prevented, and consequently, the seal mechanisms can be operated at the ordinary temperature without damaging the seal rubber rolls constituting the seal mechanisms.
