Definitions
- the invention relates to a method for producing an elastic material web from at least one rubber layer according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of claim 15.
- a generic method and a generic device is known for example from WO 2004/052630.
- each of the rubber sheets is formed from a guided through a nip rubber layer.
- the rubber layer is applied as an extrusion mass directly to the nip formed by two rolls.
- Each of the rubber webs thus produced is then joined together immediately in a further nip with a middle carcass path, so that a multilayer material web, which is used in particular for the production of tires arises.
- the known method and the known device is particularly suitable for relatively large material thicknesses of the material web.
- the desired material thickness is set as a function of a gap height of the nip and as a function of the modulus of elasticity of the respective material.
- the material thickness which is established after calendering is up to 50% greater than the gap height of the nip.
- the setting of a desired material thickness depends essentially on the material properties. Particularly problematic has been found To obtain as constant as possible material thicknesses over the entire width of a material web. For example, widths of 1,500 mm and above are common to provide webs for tire manufacturing.
- Another object of the invention is to produce elastic material webs, regardless of their material thickness, even with web widths of over 1,000 mm with the smallest possible thickness tolerances.
- the invention is achieved for a method in that depending on a compressive force acting in the nip in the interior of one of the rolls or both rolls respectively a hydraulic counterforce is generated, which acts within the rolls via an incompressible pressure medium on each an expandable roll shell such that the material thickness is substantially constant over a width of the material web.
- the invention is achieved in that one of the rolls or both rolls each have an expandable roll shell, on which acts an enclosed inside the roll in an annular pressure chamber incompressible pressure medium and that the rollers is associated with at least one controllable pressure source, which is connected for adjusting a hydraulic counterforce with two pressure chambers or with one of the pressure chambers in the interior of the roller.
- the invention has the particular advantage that the nip between the rolls is adapted such that despite the elasticity of the material, a material web is produced with a constant uniform material thickness.
- the nature of the nip and in particular the gap height is dependence on the respective generated in the rollers hydraulic counterforce.
- both influencing factors determining the material thickness such as the deflection of the rolls and the elasticity of the material, can be taken into account when setting the material thickness.
- very precise webs of material from a raw rubber or a non-crosslinked rubber can be produced as one or more layers.
- the method variant is preferably used, in which the hydraulic counter forces in the interior of both rollers for adjusting the material thickness of the material web are the same size.
- the rolls have the same design in terms of their diameter and their nature, so that the rubber layers in the nip are guided through the nip to the material web at the same circumferential speeds of the roll skirts.
- Start value set. With this start value, the work process begins first in order to change the starting value thereafter, depending on the material thickness produced, after a running-in phase to a so-called operating value.
- This method variant can also be improved by measuring the material thickness of the material web.
- the measured value of the material thickness is compared with a tolerance range in order to adapt the operating value of the hydraulic opposing force or both operating values of the hydraulic opposing forces in the rollers for changing the material thickness of the material web in the event of an impermissible tolerance deviation of the measured value.
- a tolerance range in order to adapt the operating value of the hydraulic opposing force or both operating values of the hydraulic opposing forces in the rollers for changing the material thickness of the material web in the event of an impermissible tolerance deviation of the measured value.
- the method variant is preferably used, in which the material web is treated in at least one further second nip formed between one of the rolls and a third roll.
- a new counterforce is generated in the interior of a roller that cooperates with the third roller. Due to the lower elasticity of the entire material web, it is thus possible to produce altered settings of the counterforce in the third roller, which makes it possible to adapt the overall setting accordingly to produce a constant material thickness.
- the erfmdungswashe method variant in which the precursor of the rubber layer is formed by an extrusion mass and fed to the nip, is particularly advantageous to produce a rubber sheet directly after the extrusion.
- the rollers are preferably driven at the same peripheral speeds.
- the rollers are preferably driven individually.
- At least one of the rolls is held in its position adjustable according to another variant of the method, wherein the compressing force is preferably generated in the nip by one or more force transmitter, which act on the movable roller.
- the roll shells of the rolls are heated or cooled by a fluid. It should be noted that despite a guided in the roll shell fluid, the extensibility of the roll shell is maintained.
- the inventive device for carrying out the method is characterized in that within each of the rollers, an individual hydraulic counterforce can be generated, which leads to a deformation of the roll shell.
- the connection between an annular pressure chamber formed inside the roller and a pressure source enables a change of the enclosed incompressible pressure medium at any time, so that dynamic processes can be compensated.
- each pressure source is assigned in each case a separate pressure chamber.
- the pressure sources are each assigned a control unit which is connected to a control device. This makes it possible to realize individual settings and controls during the production of the material web.

- This also makes it possible to produce the second generally multilayer material web with a substantially constant material thickness.
- the rubber web formed by the first nip is produced in its material thickness in such a way that together with a further fed material web, for example a carrier web and a further rubber web, it produces an optimum material combination.
