ABSTRACT:
A pressure saturator system includes a grooved mandrel and an opposed element which define a converging chamber therebetween. A web is passed through the chamber with a first side of the web adjacent the mandrel. A liquid saturant is introduced into the chamber such that the saturant contacts the second side of the web and impregnates the web as the web passes through the chamber. A gas receiving belt is passed through the chamber with the belt interposed between the web and the mandrel and in contact with the first side of the web. The belt receives gases and any excess saturant form the first side of the web as the saturant enters the web in the chamber, thereby facilitating the removal of gases from the web, improving the saturation process, and protecting the mandrel from undesired contact with the saturant. In alternate embodiments the betls is formed of a porous material or defines an array of gas receiving slots positioned against the first side of the web.
