Abstract:
1. An apparatus for manufacturing a carbonaceous heat source chip, comprising an extrusion molding machine for extrusion-molding a carbonaceous heat source rod having grooves axially extending on a circumferential surface thereof, a heat insulating material-wrapping device for wrapping the circumferential surface of the carbonaceous heat source rod extruded from said extrusion molding machine in a heat insulating material, said apparatus further comprising: a hollow pipe forming at least part of a conveying path for transporting the carbonaceous heat source rod continuously extrusion-molded by said extrusion molding machine from said extrusion molding machine toward said heat insulating material-wrapping device; and at least one air amplifier for making an airflow running through said hollow pipe in a transporting direction of the carbonaceous heat source rod, wherein: the carbonaceous heat source rod is transported by using the airflow while being dried by the airflow, and the airflow produced by the air amplifier flows only in a direction identical with the transporting direction of the carbonaceous heat source rod and contacts the entire circumferential surface of the carbonaceous heat source rod.
