ABSTRACT:
A method and mechanism for positive web transfer in a press section of a papermaking machine including an intermediate press nip formed between first and second press members with a porous felt on one surface of the web and a nonporous looped smooth surface belt of nonextensible material impervious to water passing through the nip in direct contact with the other surface of the web so that the web follows the belt downstream of the nip with the web first being pressed between an earlier press upstream of the intermediate press, and the web being removed from the belt following the intermediate press with rewetting of the web on the offrunning side of the intermediate nip due to contact with the impervious belt being eliminated.
