Claims
- 1. A calender comprising:
- two separately operable roll stacks;
- each roll stack including a top roll composed of a deflection compensation roll and a bottom roll composed of a deflection compensation roll;
- the two roll stacks being arranged one atop the other to form an upper and a lower roll stack;
- the top roll of the lower roll stack being fixedly mounted; and
- a bearing device being adapted to movably support the bottom roll of the upper stack.
- 2. The calender according to claim 1, both roll stacks being arranged in a common machine frame.
- 3. The calender according to claim 2, each roll stack including five rolls; and the machine frame including a 12-roll calender machine frame.
- 4. The calender according to claim 1,
- the top roll of the lower roll stack and the bottom roll of the upper roll stack being located on the bearing device.
- 5. The calender according to claim 1, further comprising a plurality of intermediary rolls positioned between the top roll and the bottom roll, the intermediary rolls being supported on levers.
- 6. The calender according to claim 1, a material web travel path being formed between the bottom roll of the upper roll stack and the top roll of the lower roll stack.
- 7. The calender in accordance with claim 1, the bearing device being adapted to movably support the bottom roll of the upper stack for movement within a roll plane.
- 8. A calender comprising:
- two separately operable roll stacks composed of a plurality of rolls;
- each roll stack including a top roll composed of a deflection compensation roll and a bottom roll composed of a deflection compensation roll;
- the two roll stacks being arranged one atop the other;
- a center of each of the plurality of rolls being arranged in a common plane;
- roll out rails extend laterally to the common plane;
- bearing recesses being located adjacent to the roll out rails; and
- at least the bottom roll of an upper roll stack being supported in the bearing recesses.
- 9. A calender for processing a material web comprising:
- a first and second roll stack substantially linearly and vertically arranged;
- the first and second roll stacks being spaced from each other a distance greater than a spacing between adjacent rolls in a same roll stack;
- a roll of the first roll stack located adjacent to the second roll stack being fixedly mounted; and
- a roll of the second roll stack located adjacent to the first roll stack being movably mountable for movement relative to the fixedly mounted roll of the first roll stack.
- 10. The calender according to claim 9, each of the first and second roll stacks comprising a bottom roll movable in a direction of the linear arrangement.
- 11. The calender according to claim 9, each of the first and second roll stacks comprising a bottom roll movable in a direction transverse to the linear arrangement.
- 12. The calender according to claim 9, the first roll stack comprising:
- a top roll and a bottom roll; and
- at least one intermediate roll positioned between the top and bottom rolls.
- 13. The calender according to claim 12, the at least one intermediate roll comprising a heated roll.
- 14. The calender according to claim 12, further comprising:
- a lever;
- a stanchion, the at least one intermediate roll coupled to the stanchion via the lever.
- 15. The calender according to claim 9, further comprising:
- a stanchion located parallel to the linear arrangement; and
- a transverser coupled to the stanchion for movement parallel to the linear arrangement.
- 16. The calender according to claim 9, the first and second roll stacks being mounted on a common stanchion.
- 17. The calender according to claim 9, a bottom roll of the first roll stack coupled to a sled,
- wherein the sled facilitates removal of the bottom roll from the first roll stack.
- 18. The calender according to claim 9, the first and second roll stacks being separately operable.
- 19. A calender for processing a material web comprising:
- a first and second roll stack substantially linearly arranged;
- the first and second roll stacks being spaced from each other a distance greater than a spacing between adjacent rolls in a same roll stack;
- each of the first and second roll stacks comprising a bottom roll; and
- a sled associated with each of the first and second roll stacks for enabling movement of the bottom roll.
- 20. The calender according to claim 19, the sled comprising a bearing recess to accommodate a bearing pin of the bottom roll.
- 21. The calender according to claim 19, the sled comprising a roll-out rail arranged transverse to the linear arrangement.
- 22. The calender according to claim 19, the sled comprising a stop for restricting movement of the bottom roll.
