There are already known “dry five liters” with a filter fabric unrolling belt »in which the roller on which the used tape is wound is driven. With filters of this kind, however, the filter belt must be made particularly tear-resistant, partly to be able to absorb the forces required for movement, partly to be sufficiently stable against the grass flow passing through. be. This contradicts the requirement * to make the filter belt as simple and cheap as possible »since it is generally no longer cleaned after use, but destroyed.

The proposed filter allows äusaerst approve the ^one using sound and simple, filter cloth bands "without that can result from their low Beißfestigketfr STashteile in operation.

The object of the firing is a ÜJroekenfilter with a rolling filter to ffband _f in which the filter fabric belt is pressed in at least two counter-rotating conveyor belts that cause the filter bath to unroll »weaves at least one conveyor belt is driven»

Cross-section for the penetrating ,,, to. cleaning gaseous medium In this case, there are no solid components worth mentioning narrowed

It can also be provided that the drive of the or of the conveyor belts when the pressure falls below a certain level

The coupled switching relay is switched on and switched off when a certain pressure is exceeded If this measure is used, the new dry filter works automatically * and it is not necessary to adapt the operating status of the fan to the respective flow resistance of the filter.

A further enlargement of the usable filter belt surface leaves can be achieved by guiding the filter belt over a pulley in a V-shape.
