Abstract
Press section in a paper machine and method for replacing press fabrics therein including two separate press nips and a frame part for each press nip. Side frames of both frame parts are interconnected by upper horizontal beams in the machine direction. The upper horizontal beam at the tending side is comprised of two beam parts of which one is situated above the side frames of the frame part of the first nip at the tending side and the other is situated above the side frames of the frame part of the second nip at the tending side. The tending-side beam parts operate as a machine-direction cantilever beam so that a first beam part is supported on the second beam part and thereby on its frame part while the side frames of the first frame part are open for replacement of the fabrics in the first nip. The beam parts operate reciprocally with each other in inverse functions as a cantilever beam and as a support part when the press fabrics in the second nip are being replaced.
