COUPLING CONSTRUCTION AND METHOD FOR JOINING AND LOCKING THE ROLLS OF EXTENDED-NIP PRESS

摘要

A yoke assembly is disclosed for connecting and securing to each other rolls (1, 2) forming a nip in an extended nip press, whereby at least one of the rolls (1) of the extended-nip press includes loading means (3), advantageously at least one loading shoe for loading the endless-loop blanket (4) of one roll (1) against the other one (2) of the extended-nip press rolls so as to establish a nip (N), wherein the lower roll (1) and the upper roll (2) are dismountably connected to each other and the yoke assembly connecting the rolls (1, 2) of the extended-nip press to each other includes rotatable connecting members (7, 8) by means of which the extended-nip press rolls (1, 2) are detachably connected to each other by their bearing blocks (5, 6). The invention is characterized in that the connecting member (7, 8) comprises a first clamping surface (24) adapted slidably rotatable on the respective mating surface (20, 21) of a first roll bearing block (5) so that the first clamping surface (24) and the respective mating surface (20, 21) of the first roll bearing block (5) to be connected therewith form a pivotal joint (10, 11) about which the connecting member (7, 8) can be rotatably disengaged from the mating surface (22, 23) of a second roll bearing block (6) and, respectively, engaged with the latter mating surface (22, 23).
