Apparatus for manufacturing cushion materials

An apparatus for manufacturing a cushion material including a hollow body, a table disposed on said body and formed with apertures of predetermined shape, a hollow upper cover member movable toward and away from said table, and a plate closing the lower end opening of said upper cover member and formed with apertures of the same shape as that of said apertures of said table and aligning with the latter, said table and said plate being adapted to hold a sheet of foamed material of continuous cell structure therebetween during impregnation of a fine powdery welding material into said foamed material through said aligned apertures, said apparatus comprising a porous member disposed within said body, means for supplying air under relatively low pressure from beneath said porous member thereby providing a cloud-like floating layer of said fine powdery welding material above said porous member, and conduit means extending into the zone of said cloud-like floating layer for jetting a gas under high pressure into said cloud-like floating layer for jetting a gas under high pressure into said cloud-like floating layer thereby forceably carrying said fine powdery welding material in said cloud-like floating layer toward said apertures of said table by the gas under high pressure.
