Zusammenfassung:An apparatus for drying an embryonic web. The apparatus comprises a micropore medium having pores therethrough. The pores are the limiting orifice in the air flow used in the drying process. The micropore medium has a surface oriented towards and preferably contacting the web to be dried. This surface has a relatively low surface energy, and preferably a surface energy of less than 46 dynes per centimeter.
