Abstract
The invention relates to a method for manufacturing a roll coating onto a roll frame (1), which coating comprises a base layer (2) on the roll frame (1) and a surface layer (3) on the base layer (2). The base layer (2) is brought to its final form after the surface layer (3) has been formed and cured or solidified. The surface layer (3) is formed on the base layer (2) and cured or solidified after the base layer (2) has been formed on the roll frame (1).
Claims7
A method for manufacturing a roll coating onto a roll frame, which coating comprises on the roll frame a base layer comprising at least one heat-setting or thermoplastic polymer material layer, and on the base layer a surface layer comprising at least one heat-setting or thermoplastic polymer material layer in which method the base layer is formed on the roll frame, and the surface layer is formed on the base layer and cured or solidified after the base layer has been formed on the roll frame, and the base layer is brought to its final form after the surface layer has been formed and cured or solidified, wherein the material of the surface layer is selected in such a manner that its curing temperature is lower than that of a topmost polymer material layer of the base layer.
A roll comprising a roll frame and a roll coating on the roll frame, wherein the roll coating comprises a base layer formed on the roll frame, the base layer comprising at least one heat-setting or thermoplastic polymer material layer, and a surface layer formed on the base layer, the surface layer comprising at least one heat-setting or thermoplastic polymer material layer, wherein the material of the surface layer has a curing temperature which is lower than that of a topmost polymer material layer of the base layer.
