A device and a method for sealing a pressure air blowing hood is described. It is capable of maintaining the seal on a hood that is provided above a sintering material charging layer, on a downward-sucking type sintering machine. The seal is made from a composite material, comprising a hard rigid body, with an elastic body installed on the skirt lower-end part of the air blowing hood so as to be in slidable contact with the surface of the wintering material charging layer.
