On the downstream side of the partial applicator 10, when the insertion portions 21 are provided at both ends of the panel in the width direction, the inorganic material e as the inorganic core material c is inserted in the insertion portions 21. However, the inorganic core material (c) is composed of an inorganic fiber material (d) of rock wool material disposed in the center portion of the panel width direction, and an inorganic material of calcium silicate (e) disposed at both ends of the panel width direction. will be.

Thus, in the partial coating device 10, the adhesive is applied to both ends of the width direction of the lower metal shell b in the width direction, and the book-shaped calcium silicate inorganic material is short in the direction in which the metal shell b is sent to the application point. As the ash (e) is extended and adhered, the inorganic core material (c ...) of the rock wool material can be easily inserted between the inorganic silica material (e) of calcium silicate at both ends of the width direction of the panel.

At the rear of the insertion portion 21 into which the inorganic material e of calcium silicate (e) is inserted, the supply device 4 is arranged, and the silicic acid at both ends of the width direction of the panel is formed as a rock wool material between the inorganic material e of the calcium.
