Abstract

The press-belt filter has an arcuate entry gap 6 in the region of an arcuate sliding guide 3 which is formed by a perforated plastic shell. This plastic has very favourable sliding properties. The arcuate entry part corresponds approximately to a circle sector of 15 DEG . The frictional stresses along the screening belt running on the sliding guide are consequently not very high. <IMAGE>
