Abstract

Raw filter material is fed to a continuous band supported at its lateral edges by cushions of air generated from perforations in air pressurized chambers below the band, the pressure being maintained by a pump which also generates the vacuum at the central filtration zone of the band. The device dispenses with conventional rail supports and consequently requires less propulsive force and minimizes wear on the support and drive drums to provide an economic and efficient band filter.
