  • Tissue impulse drying
    Patent number: 6860968
    Abstract: A process for producing tissue webs is disclosed. More particularly, the present invention is directed to an improved process for drying webs. According to the present invention, a formed web still containing a substantial amount of moisture is passed through a nip formed between a press roll and a heated drum. When passed through the nip, the web is placed on a porous fabric. The web is then carried through the nip for a period of time and subjected to temperatures and pressures sufficient to create a steam front which travels through the web and expels a significant amount of moisture from the web through the porous fabric.
