摘要： A press mechanism and method for removing liquid from a traveling fibrous web such as in a paper making machine including first and second elongate extended press nips including an endless looped traveling belt passing over spaced guide rolls with first and second opposed press rolls pressed into the belt to form the extended nips between the press rolls and belt and opposed shoes within the belt pressing outwardly against the press rolls to form the extended nips with the shoes urged against the belt by opposed pistons having a liquid pressure chamber therebetween so that the reaction forces of the fluid on the pistons are cancelled with the web being carried through the nips on felts and following the belt between the nips.
