Abstract

The invention relates to a doctor apparatus (10) in connection with a roll (T) in a paper or board machine. The doctor apparatus (10) comprises a doctor beam (12) of lightweight construction and that the doctor beam (12) is arranged to pivot on bearing means (13a1, 13a2 . . . ) (pivot movement arrow L1). In connection with the doctor beam there are loading members (14a1, 14a2), a relative linear movement taking place between the loading members (14a1, 14a2) and backup surfaces (12′, 15a′) when the doctor beam (12) is being oscillated.
