Abstract
Edges of a filter band passing across an opening between two parallel rollers are sealed by a pair of slides each consisting of a downstream fixed piece and an upstream piece adjustable for the thickness of filter band used. The downstream face of the band is backed by a mesh in the plane of the fixed slide pieces, the mesh consisting of stiffened parallel with the rollers, crossed by support between them and the filter band.
