  • the lifting device (15) is designed as a hydraulic cylinder.
  • the lifting movement is performed with a simultaneous pivotal movement about a pivot bearing (16) around. This makes it possible, for example, with two lifting devices (15) for different execution of the lifting movement to specify an inclined position in the working state in order to realize a defined skew or to perform a control of a positioning of the rollers.
  • the roller carrier (6) consists of two separate rotor discs (17).
  • the rotor disks (17) are mounted in a guide track (18) of the frame upper part (4).
  • the storage is carried out using rollers (19) which are supported by the rotor disk (17) and roll along the guide track (18).
  • the rotor disk (17) has a toothing (20) in which gear wheels (21) engage in order to provide a drive for the rotor disk (17).

  • the rotor disk (17) can be rotated in this operating state by 180 °, so that the plotted above in the drawing roller (6) with the roller (7) reverses the position.
  • the production can be continued immediately. For this process, a return of the extruder head is not required.
  • the entire change process typically takes a maximum of five minutes.
  • the upper roller (6) can be exchanged for another roller (6) without the production process in the region of the roller (7) having to be interrupted. Also, after replacing the roller (6), it is possible to provide it with its optimum operating temperature using the heater (14). In the roll replacement process according to FIG. 3 In this way, an optimally prepared roller (6) can be provided.
  • the roller carrier (5) has guides (25) for the roller bearings (8) which extend relative to an axis of rotation (26) of the roller carrier (5) substantially in a radial direction (27).
  • FIG. 4 illustrates in a side view of the calender (1) the arrangement of the motors (11, 12). Due to the design of the motors (11, 12) as gear motors, a single drive of the rollers (6, 7, 9) can be carried out using bevel gear. This avoids both the use of transmission shafts and the use of additional brakes, since the engine braking properties realized also provide the necessary braking forces for an emergency stop operation.
  • FIG. 5 shows in an enlarged view a partial illustration of a cross section of the rotor disk (17) in the region of one of the rollers (19). It can be seen in particular that the rollers (19) in the illustrated production positioning in the region of a trough-like guideway (18) engage in the frame top part (4).
  • FIG. 5 illustrates a positioning of the rotor disk (17) relative to the frame top (4) during activation of the lifting devices (22). This is in the operating state according to FIG. 5 to recognize a gap (24) between the rotor disk (17) and the guide track (18). After a distortion of the components using the lifting device (22), the rotor disk (17) is pressed against the guide track (18).
