Manufacturing machine for manufacturing heat-source rod and method of manufacturing same

Abstract

A manufacturing machine manufactures a heat-source rod having a rod-like extrusion-molded article made from a combustible material with axial grooves in the cylindrical surface thereof and a heat-insulating web enveloping the article, and is provided with a apparatusfor spouting water to the web W in the process of the web W being fed to a wrapping section. The spout apparatusincludes an air vibratorwith a vibrating rod, and a flexible nozzleattached to the rodto extend across the rodand supplied with water from a rate regulating pump. While the web W is being fed, the end of the nozzlespouts water to the web W, reciprocating widthways relative to the web W due to vibration of the rod, and the water spouted dissolves a binder used in the web W to bind heat-insulating fiber, thereby forming a wet band H, where the wet band H has a waveform continuing along the longitudinal direction of the web W and provides a adhesive region for bonding the article.
