Abstract

A doctoring mechanism for removing liquid from a belt and supporting roll, and in particular a water and/or oil film from the belt and supporting roll of a paper forming machine.
In order to achieve this efficiently the doctoring mecha­ nism is located on the outgoing side of the roll relative to belt contact, and the doctor body (1) carries two doctor blades (7,9) wich are arranged to contact the roll and belt respectively to remove liquid therefrom. Furthermore the doctor body (1) serves to catch doctored liquid and the spray generated on se­ paration of the belt from the roll.
