Description
- I) Grundsätzlich für dünne Platten, z. B. 10 mm Spanplattendicke bis minimum ca. 2,0 mm
- II) Bei dicken Spanplatten = 40 mm mit extrem niedrigem Schüttgewicht von ca. 500 kg/cbm
Nach Verlassen des Rollstangen-Ausrichtbereiches "c" werden die Rollstangen 12 stetig von "a1" bis "a2" mit höherem Druck eingeklemmt, und zwar im Druckaufbau im Bereich "a1" bis "a2" in Höhe von ca. 3 bar = 0,4·HDmax der Presse (z. B. bei 50 bar maximalem Hochdruck ist dann im Bereich "a2" der beginnende Druck 20 bar).
Claims (6)
daß die Abstützung im Einlaufbereich (c, a, b) für die Rollstangen (12) von der Einlauftangente (33) bis zum Beginn (e) des Hochdruckbereichs (HD) mit stetig ansteigendem Preßdruck von 0 bar bis HDmax durch mehrere hydraulische Stützglieder (28 und 32) für den Rollstangen-Ausrichtbereich (c) kraftschlüssig und federnd, für den Preßgut-Vorverdichtungsbereich (a) und für den Kompressionsbereich (b) in zwei kraftschlüssig starre Druckbereiche gegliedert und dafür ein rechner-kontrolliertes servohydraulisch einstellbares Kraftprofil mit variablem Kompressionswinkel α steuerbar ist und
daß von Beginn Rollstangen-Ausrichtbereich (c) bis 1/4 Preßgut-Vorverdichtungsbereich (a) der Preßdruck von 0 bis HDmax/₄ ansteigend aufgebaut wird, wobei die Einlaufstrecke (c, a, b ) ab letzterem Drittel des Rollstangen-Ausrichtbereiches "c" und im Preßgut-Vorverdichtungsbereich "a" mit einer Krümmung RE zum Radius der Umlenktrommel RU mit gleichen bis zweifach größeren Radius ausgeführt ist.
