Definitions

  • the invention relates to a calender, in particular for the production of sealing plates, consisting of at least two rollers, at least one of which is adjustably mounted in the calender stand and is equipped with a counter-bending device.
  • Such a calender is known for example from DE-PS 17 29 821. However, the calender described here was not built.
  • Bombage is a constant value used to compensate for deflection for a given load value calculated or determined for such in practice.
  • Splitting force and bombage are permanently assigned to each other. This means that other loads, be they higher or lower, result in corresponding losses in the dimensional accuracy of the product.
  • the practice of manufacturing sealing plates requires different nip forces.
  • Sealing plate calenders usually have two rolls of different sizes, namely a large heated work roll on which the sealing plate is built up and vulcanized, and a smaller, usually cooled pressure roll, which has to apply the splitting force or rolling force when the sealing plate is built up. Counter bending is only conceivable on this smaller roller.
  • roller crowning and counter-bending are also known from the construction of rubber or plastic calenders.
  • the counter-bending device is then designed so that the counter-bending can act in both directions in order to always be able to adjust the corresponding compensation in the case of larger or smaller splitting forces.
  • the different directions of force of the counterbend bring with it so considerable problems in the construction of sealing plate calenders that even this combined type could not be used.
  • the invention avoids the disadvantages of the prior art. It is the object of the present invention to design a calender with a large, heavy roller firmly mounted in the calender stand in such a way that the counter roll, which is displaceably arranged in the calender stand and is preferably equipped with a hydraulically actuated counter-bending device, can be subjected to defined and easily measurable forces.
  • the invention consists in that a displaceably mounted carrier is provided in the calender stand, on which Both supports for the bearings of the roller equipped with the counter-bending device and the counter-bending devices are mounted and on which the adjusting devices for the roller adjustment act.
  • the adjustment devices for the roller adjustment move the support of the counter-roller equipped with counter-bending devices.
  • the counter-bending forces can thus act and be measured on the roller independently of the contact forces.
  • the contact forces can in turn be measured and adjusted independently of the counter bending forces.
  • sealing plates can thus be produced with high precision.
  • the design effort is easily manageable. Since the large, heavy heating roller of a sealing plate calender is fixedly mounted in the calender stand in this embodiment, the transmission of the driving forces to this large, heavy roller presents no problems.
  • the counter-bending device must be designed in such a way that both positive and negative deflection of the counter-roller is possible.
  • the counter-bending devices are double-acting hydraulic piston-cylinder units in which the piston surfaces which can be acted upon are preferably 1: 2 in each case.
  • roller axes and the carrier are arranged on an inclined plane.
  • the sealing plate calender shown in the drawing consists of a large, heavy heated roll 1 and a smaller and lighter, cold or cooled counter roll 2 in diameter, which are supported by bearings 3, 4.
  • the bearings 3 of the stimulating roller 1 are fixedly mounted in the calender stand 5, while the bearings 4 are supported by a support 12 which is displaceable in a recess 13 of the calender stand 5.
  • Each support 12 is attached to the carrier 8, which is also slidable in this recess 13.
  • This carrier 8 carries at its outer ends hydraulic cylinder piston units 7, the pistons of which are connected to the bearings 6.
  • the bearings 6 and the hydraulic cylinder-piston units 7 form the counter-bending device.
  • the piston rods of the hydraulic cylinder / piston units 9, which are used for the roll adjustment, act on the carrier 8. These hydraulic cylinder-piston units 9 are attached to the calender stand 5. The forces
