Abstract
A packaging machine for making filter bags with infusion products including a plurality of processing stations and a cleaning unit. The processing stations define a processing path and are configured for making infusion products. The cleaning unit is configured for removing dust from the processing path and in turn includes a generator device positioned above the processing path and configured for generating a flow of air designed to push the dust beneath the processing path; at least one ventilation grille coupled to the generator device and designed to convey the flow of air along a predetermined direction of emission which extends around the processing path and at least one suction device positioned the processing path and configured for sucking the dust promoting the evacuation from the machine.
