Definitions
- the present invention relates to a roller, in particular for smoothing of paper webs, with a hard one consisting in particular of metal Roll core, on the outside with an elastic reference layer is provided, which is made of an elastic matrix material and into the matrix material embedded fibers. Furthermore, the invention is based on directed a method of manufacturing such a roller.
- Elastic rolls of this type are used, for example, when satinizing paper webs.
- An elastic roller forms a press nip together with a hard roller through which the paper web to be processed is passed. While the hard roller has a very smooth surface, for example made of steel or chilled cast iron, and is responsible for smoothing the side of the paper web facing it, the elastic roller acting on the opposite side of the paper web causes the paper web to be leveled and compressed in the press nip. The elasticity of this second roller thus prevents excessive compression of the paper web, which would lead to a greasy appearance of the paper web.
- the size of the rollers is 6 to 12 m in length and 800 to 1500 mm in diameter. They withstand line forces up to 600 N / mm and compressive stresses up to 50 N / mm 2 .
- plastic coverings maximum temperature differences of about 20 ° C over the The width of the roller is permissible and on the other hand they are for the coating
- plastics used are much higher Thermal expansion coefficients than those commonly used Steel rollers or chill cast rollers, so that by an increase in temperature high axial tensions between the steel roller or chilled iron roller and the associated plastic coating occur.
- the part of the task relating to the roller is based on the invention solved by a roller of the type mentioned in that the The fiber content of the reference layer varies radially from the inside out, in particular decreases.
- a corresponding method according to the invention is characterized in that the fiber content of the reference layer in radial Direction is varied, in particular is reduced radially outwards.
- the reference layer has a coefficient of thermal expansion has, which also in accordance with the fiber content radial direction is different from the inside to the outside. Because usually the matrix material has a significantly higher coefficient of thermal expansion has as the fiber material used, is therefore the respective resulting coefficient of thermal expansion of the interspersed with fibers Matrix material both from the coefficient of thermal expansion of the Matrix material as well as that of the fibers. The more fibers in embedded in the matrix material, the more the resulting one looks the same Coefficient of thermal expansion is the coefficient of thermal expansion of the fibers used.
- the fiber content is high, the stiffness of the cover layer is also clear increased, must in the radially outer areas of the reference layer the fiber content should be chosen lower, otherwise the surface the roller is too hard and would not be suitable for santinage.
- a especially essentially continuously decreasing radially outward Fiber content within the reference layer is achieved in that when the roller is heated, those occurring within the reference layer Longitudinal stresses due to the different thermal expansion of the different areas of the reference layer never become so large that a detachment or destruction of the reference layer arises.
- the invention is in the radially outer Area of the reference layer of fiber content essentially equals zero. This ensures that the surface of the roller is as possible is elastic and after a corresponding grinding process has a very smooth surface because the existing ones in the reference layer Fibers do not reach the surface of the reference layer. Farther is ensured in this way that the surface of the roller after a can be resharpened for a certain period of time without the need in the matrix material fibers present on the surface after the grinding process the reference layer emerge from it and thereby the smoothness of the surface would decrease.
- the nip width can also be selected by a suitable choice of the fiber content curve be set as required. Because with a roller with one very elastic covering the hard counter-roller is stronger in the soft Pressing the surface of the elastic roller, the width of the nip in the running direction the more elastic the outside of the Reference layer of the elastic roller is. Thus, by hiring a certain course of fiber content and in particular a certain one A desired fiber content on the surface of the reference layer Nip width can be generated.
- the reference layer a radially outer functional layer and a radially inner connection layer for connecting the functional layer with the roller core.
- the connection layer like that Functional layer, made of an elastic matrix material and into the matrix material embedded fibers exist, preferably the matrix material the connection layer and the functional layer from the same Material and in particular also the fibers of the connection layer and the functional layer consist of the same fiber material.
- the matrix material of the Link layer in fiber bundles or so-called fiber rovings, i.e. in flat slivers, each comprising fibers of the same type the roll core are wound up while the fibers of the functional layer for example in the form of a nonwoven fabric on the connecting layer can be wound up.
- the fiber content of the connecting layer is preferably higher than the fiber content the functional layer, because in this way the connection layer is fiber-dominated and the coefficient of thermal expansion of the connecting layer mainly due to the coefficient of thermal expansion the fibers is determined. This can result in the coefficient of thermal expansion the connection layer at the coefficient of thermal expansion of the roller core can be adjusted.
- the Functional layer described is achieved in that in the case of a Longitudinal stresses occurring evenly over the radial Extension of the reference layer is distributed and therefore not at any Place longitudinal stresses that lead to a violation of the reference layer to lead.
- the fiber content is Connection layer in its radially outer area essentially the same size as the fiber content of the functional layer in its radial inside area. This will affect the thermal expansion a continuous transition between the tie layer and the Functional layer created, so that in this transition area a voltage-optimized connection is created.
- Those are preferred Fibers arranged in radially spaced fiber layers, wherein especially the distance between radially outer neighboring ones Fiber layers is greater than the distance between radially inner fiber layers. Due to the elastic matrix material between the fiber layers is achieved that the reference layer in the longitudinal direction retains certain elasticity, so that those which occur when heated Longitudinal expansion can be compensated well.
- the fiber content of the connecting layer is preferably approximately 40 to 70 Vol .-%, in particular about 50 to 60 vol .-%, preferably about 55 vol .-%.
- the fiber content of the connection layer is both its stiffness, Thermal conductivity and the total coefficient of expansion determined.
- the relatively high fiber content also results in high thermal conductivity reached the connection layer, so that the heat of im Operation overheating points quickly discharged axially to the outside can be avoided so that hot spots are prevented.
- the fiber content is Functional layer preferably about 5 to 20 vol .-%, in particular 8 to 12 Vol .-%.
- the functional layer maintains due to the reduced fiber content less rigidity than the tie layer, as used for uniformity and compression of the treating paper web in the Satinage is required. If due to the reduced fiber content Thermal expansion coefficient of the functional layer can be too large this is achieved by adding fillers to the matrix material the functional layer can be reduced.
- Fig. 1 shows a part of a cut in the longitudinal direction, for example made of steel roller core 1, the outside with a elastic reference layer 2 also shown cut is.
- the reference layer 2 consists of an elastic matrix material 3, in particular a resin / hardener combination in which a variety of fibers 4 are embedded.
- the fibers 4 can be, for example Carbon fibers or around glass fibers or around a mixture of carbon and Trade fiber optics.
- the fibers 4 contrast the stiffness of the reference layer 2 a reference layer made of pure plastic increased and at the same time, especially when using carbon fibers, the thermal conductivity improved.
- the fiber content in the radially inner Area 5 of the reference layer 2 is significantly higher than in its radially outer region 6. This ensures that the reference layer 2 in its radially outer region 6 is more elastic than in its radially inner region 5, so that, for example, when interacting the elastic roller with a hard roller itself hard roller relatively far into the elastic outer surface of the reference layer 2 presses in, which creates a long press nip in the circumferential direction.
- the thermal expansion coefficient is also due to the fibers 4 the reference layer 2 is significantly determined.
- the metallic roller core 1 usually has a significantly lower coefficient of thermal expansion possesses as the matrix material 3, the matrix material expands 3 clearly with a corresponding heating in the axial direction more than the roll core 1.
- the fibers 4, whose Coefficient of thermal expansion in the order of the coefficient of thermal expansion of the roll core 1 is achieved in the area 5 of the reference layer 2, which has a high fiber content the resulting Coefficient of thermal expansion is similar to that of the roll core 1.
- area 5 expands when heated accordingly in the axial direction by a value similar to that of the roll core 1, so that axially occurring longitudinal stresses are largely avoided.
- the fibers 4 are inside of the matrix material 3 as essentially concentric with the roll core 1 running fiber layers 7 is shown schematically.
- the fiber layers 7 can, for example, by winding fiber rovings are generated on the roll core 1, whereby to form the reference layer 2 several wrapping operations are carried out to make several To produce fiber layers 7.
- the fibers or fiber rovings can be in the liquid state matrix material 3 are applied by they are pulled through a matrix bath, for example. However, it is also possible that the fibers or the fiber rovings dry on the roller core 1 can be wrapped and during or after winding with Matrix material are soaked until completely surrounded by it are.
- the fiber layers 7 have in the radially inner region 5 of the reference layer 3 a significantly smaller distance from one another in the radial direction than in the radially outer area 6, with the outermost area there are no fibers in the reference layer 2, i.e. that in this area the pure matrix material 3 is present.
- the uppermost layer of the matrix material 3 is ground off during the winding process.
- the fiber-free design of the radially outer area of the Reference layer is achieved that even after repeated regrinding no fibers 4 reach the surface of the reference layer 2 and thus this surface has an optimal smoothness.
- Line 8 divides the reference layer 2 into a radially outer one Functional layer 9 and a radially inner connection layer 10 shown for connecting the functional layer 9 to the roller core 10.
- Both the functional layer 9 and the connection layer 10 exist a matrix material 3, 3 'with fiber layers 7 embedded therein, 7 ', preferably both the matrix material 3, 3' and the fiber layers 7, 7 'forming fiber material are chosen the same. Basically however, it is possible to use different materials, if this better meets the desired requirements.
- the fiber layers 7 ′ of the connecting layer 10 by winding fiber rovings and the fiber layers 7 of the functional layer 9 is generated by winding a nonwoven fabric.
- a fleece the fibers are usually unevenly distributed and shorter than is the case when winding fiber rovings.
- the non-woven fabric therefore has a higher level of flexibility, than would be the case when using fiber rovings.
- the tensile strength as well as the thermal conductivity of the functional layer improves because the fibers of the nonwoven are in intensive engagement with each other.
- the reference layer 9 for example between 10 and 90, preferably between 40 and 50 fiber layers 7 included.
- the connecting layer 10 usually has a smaller thickness than the functional layer 9, due to the closer arrangement of the fiber layers 7 ', however, the number of fiber layers 7' used can be similar the number of fiber layers 7 of the functional layer 9.
- a typical one Thickness for the connection layer 10 is between 3 to 10mm, while the functional layer 9 can have a thickness of 5 to 20 mm.
