ABSTRACT:
A saturator of the type which includes a chamber situated between a chamber defining element and a mandrel, in which a web is moved through the chamber to impregnate the web with a saturant contained in the chamber, includes a chamber defining element which defines an array of grooves. The grooves are separated by raised surfaces. The raised surfaces cooperate with the mandrel to pressurize the saturant in a high pressure zone which causes a relatively large amount of saturant to enter the web. The grooves define respective low pressure zones, which cause a reduced amount of saturant or no saturant to impregnate the web. A desired pattern of impregnation of the web can be obtained by properly positioning the grooves with respect to the raised surfaces on the chamber defining element.
