Definitions
- the invention also relates to a calender arrangement for calendering a material web, especially a paper or board web, the said arrangement comprising a long-nip calender, in which the backing roll of the long-nip roll is a heated, metal-surfaced roll, the rolls of which form a long nip between them, the length of which in the direction of travel of the web is within the range from approximately 10 mm to 500 mm.
- the method relating to the invention is characterised in that as a long-nip roll is used a roll, the belt mantle of which is made of metal, at least as concerns its calendering, longitudinal, central area; that in the method, a nip pressure within the range from about 0.1 MPa to about 50 MPa is directed at the material web W, and that the surface temperature of the rolls before the nip N is adjusted to a value from about 60°C to about 350°C.
- the nip pressure is preferably within the range from about 0.2 MPa to about 15 MPa, and the surface temperature is preferably within the range from about 120°C to about 300°C.
- the calender arrangement relating to the invention is in turn characterised in that the belt mantle of the long-nip roll is made of metal, at least as concerns its calendering, longitudinal, central area.
- Figure 1 shows a diagrammatic view of the long-nip calender arrangement relating to the invention, as seen from the end, and
- Figure 3 shows a diagrammatic view of another embodiment of a belt mantle of a long-nip roll applicable to the calender arrangement relating to the invention, as seen from the end.
- Figure 3 shows a solution in which a thin-walled metal cylinder 41 is fitted over the polymer belt 40 of a shoe roll 15, the cylinder being tightened in place by means of the internal air pressure of the roll.
- the length of the cylinder 41 is the same as the width of the material web and it is not fixed to the end structures of the shoe roll, whereby loading causing fatigue in metal materials is avoided in the edge area of the shoe.
- the surface temperature of the rolls before the nip IM is adjusted to a value from about 60°C to about 350°C, and preferably to a value from about 120°C to about 300°C, when the surface temperature used in conventional machine calendering is typically within the range from about 60°C to about 120°C.
- the length of the nip N in the direction of travel of the material web is preferably within the range from about 10 mm to about 500 mm.
- the surface roughness R a of both the steel belt 30 of the long-nip roll 15 and of the outer surface of the backing roll 11 is preferably less than 0.3 ⁇ m, whereby the material web W can be subjected to gloss treatment.
- the solution relating to the invention is applicable to both on-line use and off-line use. It is conceivable to use the calender arrangement relating to the invention, for example, on the press section for drying the material web, for pre-calendering before the coating machine and for final calendering after the coating machine.
