Abstract
The open inlet end of a microscreen drum is defined by a circular track which is supported on rollers above the flow. The stationary wall supporting the rollers carries a flange-type flexible seal extending in a partial circle around the opening in the wall. The track carries a fully circular flange and a low-friction, slit tubing covers its axially projecting edge and is engaged by the flexible seal.
