A roll blade assembly for a paper coating machine, comprising a frame (5), a support mounted on the frame (5), a blade member (8) mounted on the support (3), a set of mounting accessories (1, 6, 7) for attaching the inner longitudinal end of the blade member (8) to the support (3), a bar unit (9) provided with a rotating metering bar (10) and, attached to the blade member (8), and a pneumatically inflatable loading bag (2) arranged to push the bar unit (9) outwards from the support (3) when the inflation pressure is raised. The blade member (8) is flexible, and the support (3), the bar unit (9), and the blade member (8) form a recess (4) compliant with the loading bag profile and extending in the lateral direction of the blade member (8) over at least 50 percent of the unobstructed blade width. The large inflated bag contact surface makes a more accurate control of the metering bar pressing force possible by directly contacting the blade member. |
