ABSTRACT:
A pressure saturator for impregnating a substrate with a saturant is disclosed, having a block member with an arcuate, sloping upper surface that is graduated from a relatively deep portion to a relatively shallow portion. Rollers are disposed on each side of the block member for conveying the substrate into and out of the saturator, and a mandrel is disposed between the rollers for guiding the substrate through the saturator. The lower portion of the mandrel is spaced from the block member and extends into the recess formed by the arcuate surface to define a chamber therebetween. The chamber has an inlet and an outlet for admitting the substrate and the saturant, and converges in depth from the inlet region to the outlet region to pressurize the solution and force the saturant into the interstices of the substrate.
