ABSTRACT:
A roll is supported at the middle thereof, for a paper, board or finishing machine is composed of two sections, a so-called inner shell (54′) and an outer shell (52′), supported by one another in the middle area of the roll (50′). The nominal stiffness of the manufacturing material of the inner shell (54′) of the roll is substantially greater than the nominal stiffness of the manufacturing material of the outer shell (52′) of the roll.
