Abstract (en)

The calender assembly, for processing webs of paper and similar materials, has a stack of calender rollers on a plane (E) at an angle to the horizontal. The rollers are on the angled upper side of the pillars. At least one roller (6) is moved upwards by a setting mechanism (49), at right angles to the common roller plane (E). The setting mechanism (49) moves the roller (6) outwards sufficiently for it to be grasped directly at the roller ends by a crane (48), to be lifted upwards clear of the calender. The hydraulic setting mechanism (49) moves the roller (6) along a guide. The calender roller (6) has a bearing pedestal which is in a release fitting at a carrier lever (27) at the pillar. The setting mechanism (49) has a hydraulic cylinder and piston, along the roller carrier lever (27). The setting mechanism (49) has a trough to support an end of the roller (6), carried by a slide between the hydraulic cylinder and the lever (27), mounted to the piston. The removable roller (6) is a center roller in a roller stack. The common roller plane (E) is at an angle of 30-60 degrees to the horizontal or 45 degrees .

Abstract (de)

Eine Kalanderanordnung für Bahnen aus Papier oder ähnlichem Material weist einen Ständer und einen Stapel daran gehaltener Walzen auf. Deren Achsen liegen in einer etwa parallel zu einer Ständerseite verlaufenden gemeinsamen Ebene (E). Diese gemeinsame Ebene (E) verläuft schrägt zur Horizontalen. Die Walzen sind an der schrägen Oberseite des Ständers angeordnet. Mindestens eine Walze (6) ist mittels einer Stellvorrichtung (49) etwa rechtwinklig zur gemeinsamen Ebene (E) nach oben verlagerbar. Auf diese Weise sind die Walzen zwecks Auswechslung besser zugänglich. <IMAGE>
