Abstract (en)
[origin: EP2108736A2] The method involves providing a suction roll sleeve (2) with a pass-through opening. A set of material characteristics of the roll sleeve is altered with regard to an increase in resistance against vibratory fissure corrosion in a localized area of the roll sleeve corresponding to the opening, where the resistance occurs by introducing a set of internal stresses or through a structural change in the roll sleeve. The stresses are produced mechanically through plastic deformation. A tool e.g. ball, with a diameter which is larger than a diameter of the opening is inserted via the opening. An independent claim is also included for a roll sleeve for a paper machine, comprising a pass-through opening.
