CENTRAL FED ROLLER FOR FILAMENT EXTENSION ATOMIZER

A roller (300) has an outer cylindrical surface having an array of holes, a central feed channel (302) inside the roller (300), and veins (304) connecting the channel (302) to the holes, forming a path for liquid between the channel (302) and the holes. An atomization system having a fluid reservoir...

More Information
Summary:A roller (300) has an outer cylindrical surface having an array of holes, a central feed channel (302) inside the roller (300), and veins (304) connecting the channel (302) to the holes, forming a path for liquid between the channel (302) and the holes. An atomization system having a fluid reservoir (312); a pair of rollers (300, 400), at least one (300) of the rollers (300, 400) having: a central feed channel (302), the channel (302) fluidically connected to the fluid reservoir (312), an array of holes on a surface of the roller, and veins (304) connecting the channel (302) to the holes, a nip (402) formed between the rollers (300, 400), and a receiving surface positioned to receive droplets formed when liquid exits the holes, stretches between the rollers (300, 400) as they counterrotate to form filaments and the filaments break into droplets.
