摘要： A press roller having a stationary carrier and a roll jacket which rotates past the support surface of the stationary carrier. A support element on the carrier, like a shoe, is pressed against the inside circumferential surface of the roll jacket by a pressure space that is beneath and acts upon the support element to press it toward the roller jacket. The support surface is at least partially hydrodynamically lubricated at the support surface of the support element. The support surface has at least one row and perhaps a plurality of rows that extend in the direction of the press roller axis comprised of a plurality of oil feed points which are separated from one another along the roller axis. The oil feed points are supplied at least partially independently of the pressure space. Each oil feed point comprises a throttling bore. One or more distribution channels in the support element deliver oil to the bores or to groups of the bores.

摘要： 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.
