The board web glides above the smooth coating with the aid of fluid lubricant, the lubricant being supplied to the smooth coating through supply openings and discharged therefrom through discharge openings. Each groove in the smooth coating is formed with an opening therein either as a supply or discharge opening, each groove having a lubricant supply opening being positioned adjacent a groove having a lubricant discharge opening. Means are provided for controlling the pressure in at least some of said grooves for generation of a counter-pressure.

Description

Die Erfindung betrifft eine Presse gemäß dem Oberbegriff des Hauptanspruchs. Eine solche Presse ist bekannt (EU-OS 52.359) und hat sich bewährt, jedoch ist die Ausbildung des Gleitmitteldruckfilms über die Länge und Breite des Preßbereichs und damit auch die Wärme- oder Kälteverteilung bei einem erwärmten bzw. gekühlten Gleitmittel ungleichmässig.The invention relates to a press according to the preamble of the main claim. Such a press is known (EU-OS 52.359) and has proven itself, but the formation of the lubricant pressure film over the length and width of the press area and thus also the heat or cold distribution with a heated or cooled lubricant is uneven.

Der Erfindung liegt daher die Aufgabe zugrunde, den Gleitbelag einer Presse gemäß dem Oberbegriff des Hauptanspruchs so weiterzubilden, daß die jeweils vollflächige Gleitmitteldruckfilmausbildung und hierdurch die Wärme- oder Kälteverteilung des Gleitmittels sowie im zu behandelnden Gut vergleichmäßigt ist. Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Hauptanspruchs gelöst.The invention is therefore based on the object of developing the slide coating of a press in accordance with the preamble of the main claim so that the respective full-surface lubricant pressure film formation and thereby the heat or cold distribution of the lubricant and in the material to be treated is evened out. This object is achieved by the subject matter of the main claim.

Die einzige Zuführöffnung in jeder Nut im Gesamtsystem von zumindest im wesentlichen gleichmäßig verteilt angeordneten und sich gleichsam überlappenden Gleitmitteldruckfilm-Teilfeldern nach der Erfindung hat zur Folge, daß diese vollständig mit dem unter Druck stehenden Gleitmittel ausgefüllt wird. Hierbei übernimmt das Gleitmittel im Bereich der Nut die auf das Band lastenden Flächenkräfte - im Bereich dieser Nut -. Zugleich wird das Gleitmittel zwischen das Band und den Gleitbelag in Form eines Gleitmittelfilms gepreßt, so daß der Gleitbelag gut und äußerst gleichmäßig geschmiert ist. Die Drucksteuerung in der jeweiligen Nut mit der Abführöffnung bewirkt, daß gerade auch in diesem Bereich ein Teil der auf dem Band bzw. an dem Gleitbelag lastenden Flächenkräfte von dem Gleitmittel bei nunmehr vergleichmäßigter Druckverteilung aufgenommen wird. Insgesamt ergeben sich somit recht gleichmäßige Druckverhältnisse in allen Gleitmitteldruckfilm-Teilfelder ein außerordentlich niedriger Reibungsbeiwert und überdies ei ne entsprechend vergleichmäßigte Wärme- oder Kälteverteilung des Gleitmittels und folglich auch im zu behandelnden Gut. In zweckmäßiger Ausgestaltung der Erfindung wird die Befestigung des Gleitbelages oder von dessen Teilbereichen in den Nuten - anstelle gesonderter Befestigungen an anderer Stelle - vorgenommen. Infolgedessen wird die für den Gleitmittelfilm wirksame Fläche nicht zusätzlich verkleinert, so daß - hierdurch bedingt - auch keine größeren Flächenkräfte entstehen, welche durch Scherkräfte Abrieb und damit geringe Haltbarkeit und kleinere Standzeiten bewirken.The only feed opening in each groove in the overall system of at least substantially uniformly distributed and, as it were, overlapping lubricant pressure film subfields according to the invention has the result that it is completely filled with the pressurized lubricant. Here, the lubricant in the area of the groove takes on the surface forces on the belt - in the area of this groove. At the same time, the lubricant is pressed between the belt and the sliding coating in the form of a lubricating film, so that the sliding coating is lubricated well and extremely evenly. The pressure control in the respective groove with the discharge opening has the effect that a part of the surface forces acting on the belt or on the sliding lining is absorbed by the lubricant with a now uniform pressure distribution, especially in this area. Overall, this results in quite uniform pressure conditions in all lubricant pressure film subfields, an extraordinarily low coefficient of friction and, moreover, a correspondingly uniform heat or cold distribution of the lubricant and consequently also in the material to be treated. In an expedient embodiment of the invention, the fastening of the sliding covering or of its partial areas in the grooves - instead of separate fastenings at another location - is carried out. As a result, the area effective for the lubricant film is not additionally reduced, so that - due to this - there are also no larger surface forces which cause abrasion and thus low durability and shorter service life due to shear forces.

Zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Expedient refinements and developments of the invention are characterized in the subclaims.

Ein bevorzugtes Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung näher erläutert. Es zeigt:
