Claim 1
Independent Claim
110 words
In a sealing system for a chain conveyor, comprising a rotary drum provided with side gearwheels for the chains and central blades to define compartments for the passage of the articles to be conveyed the improvement that the chains comprise rollers mounted between pairs of lateral articulated links, the gearwheels having teeth in register with each blade, said teeth being adapted to engage between the respective links and rollers and the said teeth being flanked by check members adapted to assume positions on either side of the links and in sealing-tight connection with the blade on the one hand and a gasket associated with the gearwheel on the other hand.
