  • Apparatus for contactless cleaning of a conveying element and arrangement for transporting and/or storing of rod-shaped articles with an apparatus for contactless cleaning of a conveying element
    Patent number: 7617562
    Abstract: The invention concerns an apparatus for the contactless cleaning of a conveying element which is designed to receive rod-shaped articles in the tobacco-processing industry, including at least one ionising element for removing electrostatic charges on the surfaces of the conveying element to be cleaned, at least one rotating compressed-air nozzle for loosening and removing contaminants located on surfaces of the conveying element, and a suction device for extracting the contaminated outgoing air, characterized in that associated with the apparatus is a housing for forming a cleaning chamber at least partially shielded from the environment, whereby the cleaning chamber has an inlet opening and an outlet opening for the conveying element to be cleaned, such that upper side and lower side of the conveying element are surrounded. Furthermore, the invention concerns an arrangement for transporting and/or storing rod-shaped articles with an apparatus for contactless cleaning with the above-mentioned characteristics.
