ABSTRACT:
A cantileverable roll for use in a roll press, wherein the cantileverable roll cooperates with a backing roll. The cantileverable roll has a rotating surface and is either a solid rotatable roll body or a stationary roll body with a rotatable shell around it. A journal at each end of the cantileverable roll is supported in a respective bearing bracket. At one end of the roll, preferably the drive end, there is a non-rotating extension piece which extends out axially from the roll body and is fastened to the bearing bracket at that end. A tension bar or the like connects the extension piece to a stationary structural part and introduces force in the roll body which compensates for the weight of the roll when the other end of the roll is temporarily unsupported and the roll is cantilevered. The backing roll may also be cantilevered. The various techniques for supporting the one end of the roll by using the coupling element from the extension piece to the frame of the paper making machine are disclosed. The cantileverable roll and the roll press are particularly useful in a paper making machine.
