Abstract: A roll has a roll body having a central bore and a first end and a second end. Roll necks are flange-mounted to the first and second ends of the roll body, respectively, for supporting the roll body in bearings. At least one compensation weight is eccentrically arranged in the central bore. The at least one compensation weight is adjustable with regard to its mass, an angular position within the roll body, and/or a radial spacing relative to a central axis of the roll body. The at least one compensation weight is adjustable while the roll necks are flange-mounted on the first and second ends.

Abstract: The invention relates to a calender bowl which can be heated by means of a heating medium that is in a liquid or gaseous state of matter. The calender bowl comprises a roll body (1) that is provided with peripheral bores (4) and flange journals (2, 3) comprising supply and discharge conduits for the heating medium. Thermal insulating bushes (8) are mounted on the end areas of the peripheral bores. The heating medium flows through the peripheral bores. The aim of the invention is to adapt the heat transfer from said bores to the lateral surface of the roll body to the respective heat requirements in such a way that the harmful measured differences stay within limits so that the product is not impaired. To this end, adjusting devices are allocated to the flange journals for controllably turning and/or axially displacing the insulating bushes.

Abstract: A paper processing roll for use in a calender of a paper-making machine which during operation can be exposed to increased temperatures is provided with a heat-treated surface which is produced by hot-grinding or hot-balancing or both.

Abstract: A thermally regulatable calender roll, e.g. for drying paper webs, can have a roll body centered on a pair of flanged stub shafts whose flange on at least one end of the roll body can be provided with at least one annular groove or chamber communicating with the heating bores of the roll body. The pitch circle of the heating bores is located outwardly of the pitch circle of the bolts attaching the flanges to the roll body and the heating medium is fed through at least one of the stub shafts to the annular groove and the bores.
