<p>Extended-nip press for dewatering of a paper or board web, comprising a counter-member (10), which forms an extended press zone (S) together with a press-glide shoe (33) and a glide belt (40) running around the shoe. Through said zone (S), at least one dewatering fabric (50) and the web (W) from which water is removed and which is supported by said fabric are passed. The glide belt (40) is passed over a leading and tensioning member (43;70), and the closed loop of the glide belt (40) is guided around its leading and tensioning member (43;70) so that, between said leading and tensioning member (43;70) and the glide shoe (33) and its possible guide parts (33a,33b), if any, the glide belt (40) has, as a rule, substantially straight runs (40a,40b). The space enclosed by the glide belt (40) and susceptible of oil splashes is closed at both of the end areas of the loop of the glide belt (40) by means of wall constructions (42a,42b), which may, if necessary, be provided with expansion joints (61) fitted in such a way that movements of the glide shoe (33) and of the leading and tensioning member (43;70) for the glide belt (40) in relation to one another are possible.</p> |
