Abstract
A seal construction for a suction roll in a paper machine including a substantially U-section holder open toward an inner face of the roll mantle and a seal mounted in the holder and extending in the axial direction of the roll. The seal includes a frame part arranged within the holder and a wear part fixed to the frame part and placed against the inner face of the roll mantle. The seal construction also includes a loading hose for shifting the seal in the holder against the inner face of the roll mantle. In the interior of the frame part of the seal, an inner loading member is arranged to lock the frame part of the seal in contact with the holder so as to position the wear part of the seal in the desired position in relation to the inner face of the roll mantle.
