DEVICE FOR MAINTENANCE OF A ROLL OF A FIBER WEB MACHINE

摘要

The invention relates to a device for the maintenance of a roll of a fiber web machine which comprises a grinding means (20) for the maintenance of a surface/cover of a roll (10). The grinding means (20) of the maintenance device is arranged to grind wave-type deformations (12) in the surface/cover of the roll (10) of the fiber web machine passing in the longitudinal direction of the roll. The grinding means (20) comprises a curved contact area which simultaneously extends at the point of at least two crests (13) of the wave-shaped deformation (12) in the surface/cover of the roll (10) and into connection with the curved contact area is arranged abrasive material (25).
