ABSTRACT:
An airlock for the continuously feeding through of a material while obstructing the free flow of a gas is provided. The airlock comprises a first continuous belt having a plurality of nonporous flaps projecting out from it. Each flap has a free edge located outwardly from the belt. A second belt runs parallel to the first and has elements to seal against the free edges of the flaps of the first belt. A motor moves the belts so that their transport sides move together. Particulates are transported in the chambers formed by belts and flaps while the flow of air between and past the belts is inhibited.
