Abstract
Press device for treating a material web that may includes an impermeable press element having a press face, an opposing element, and a nip formed between the press element and the opposing element. The press device may also include a felt belt that guides the material web through the nip and that is positioned between the material web and the opposing element. The material web may be separated from the press element after leaving the nip because the press element may further include at least one of grooves and holes formed in the press face that close in the nip due to pressing forces to form a smooth surface, and that open after leaving the nip.
