Cleaning device for flanged reels

A device for cleaning from the surfaces of flanged reels, especially magnetic tape reels, dust and dirt particles, said device comprising:

• a means for conveying the reels along a path of gas nozzles in such a position that both outer flange surfaces, both inner flange surfaces and the hub surfaces of said reels are accessible by several jets of cleaning gas leaving said gas nozzles, whereby each gas nozzle is capable of and suitably arranged for directing a jet of gas onto a surface of said reels as they are conveyed and the impacting of said gas on said surface removes said dust and dirt particles therefrom;
• said path of gas nozzles comprising at least three groups of gas nozzles, each group consisting of at least one gas nozzle, the first and second groups of gas nozzles being respectively positioned along said path to direct gas onto each of said outer flange surfaces of said reels and the third group being positioned along said path to direct gas onto both of said inner surfaces and the hub of said reels;
• a means for ionizing the jets of cleaning gas whereby the static charge on the surfaces of said reels is neutralized so as to enable the easy removal of dust and dirt particles therefrom by said cleaning gas;
• and
• a suction device for withdrawing the dust and dirt particles as they are removed from the vicinity of the cleaned surfaces.
