ABSTRACT:
A saturator of the type comprising a chamber situated between a chamber defining element and a mandrel, in which a web is moved between the chamber defining element and the mandrel to impregnate the web with a saturant contained in the chamber includes at least one saturant delivery port which extends across substantially the entire width of saturation zone which extends only partially across the web if the chamber defines a plurality of saturating zones. In this way, uniformity of saturation across the chamber is improved.
