FUNCTION
In the tandem roller system (TRS), sweeping materials are first conveyed by means
of the side brush (a) from the corners and edges of the sweeping area into the
center of the machine and therefore towards the two counter-rotating roller brush
(b). From this, the sweeping material is taken up and conveyed into the dirt-hopper
(c) situated at the back. The dust stirred up by the sweeping process is vacuumed
up by a vacuuming system (fan) (d), filtered by flat-pleat filter (e) and thus
separated from the clean air. Filter cleaning (f) removes the dust caked onto the
flat-pleat filter and allows this to drop into the dirt-hopper.
