A continuously operating press is described for the manufacture and/or coating of board webs consisting of a fleece or mat in which the press belts are supported on a lubricant film formed on a slide lining. For the marginal width adjustment of the press zone the slide linings are subdivided into a main zone and adjoining marginal strip zones respectively. In one embodiment of the invention transition zones are in each case provided between two of these slide lining zones and are either made groove-free or provided with blind grooves, which serve neither as supply nor as discharge for lubricant. In a further embodiment of the invention adjacent grooves in these slide lining zones are alternatively provided with supply and discharge openings for the lubricant.
Cette invention concerne une presse en continu servant à la fabrication et/ou au revêtement de panneaux de non tissé ou de feutre et dont les toiles de pressage glissent sur une pellicule de lubrifiant formée à la surface d'une sole de glissement. En vue du réglage de la largeur de travail de la zone de pressage, les soles de glissement sont subdivisées en une zone principale et des bandes marginales adjacentes. Dans une variante de l'invention, des zones de transition sont prévues dans chaque cas entre ces deux zones de la sole de glissement, les dites zones de transition étant soit pleines soit dotées de gorges borgnes qui ne servent ni à l'amenée ni à l'évacuation de lubrifiant. Dans une autre variante de l'invention, les gorges adjacentes pratiquées dans ces zones de la sole de glissement comportent alternativement des orifices d'amenée et des orifices d'évacuation de lubrifiant.
