摘要： A system for treating a porous web with a liquid treatment liquid continuously moves the web along a path sequentially through a saturating station, steaming station, and drying station. A drum in the saturating station engages a back face of the web and a trough closely surrounds the drum and confronts a front face of the web. Seals form between the drum and trough a generally closed and pressurizable chamber through which the web passes and which is supplied with the treatment liquid at superatmospheric pressure so as to force the liquid against only the front face of the web. In the steaming station jets of steam are directed against the back face of the web to heat the web and disperse the treatment liquid throughout the web. The web is heated and dried in the drying station.
