Abstract
PURPOSE:To improve the deficient portion of the side of a heat insulating panel and the defective bonding of the side portions by a method in which before the rise time of raw material, a sheet material is bent and contacted and the central portion of the raw material is extended toward left and right sides by a roller. CONSTITUTION:An unexpanded polyurethane resin P is charged from an injector onto a color steel plate primarily molded, and a sheet material is guided by a roller 6 to a place where the raw material P reaches the early period of its cream time, whereupon the raw material P laminated on a Kraft paper and the inside of the decorated face of the color steel plate is doctored by a roller 6 so as to make part of the raw material P contact with the Kraft paper, and then the raw material P is flowed toward the left and right sides. Afterwards, the raw material P is gradually expanded to the entrance of a cure oven while suppressing upward expansion by an extending roller 7. Then, it is sent into the cure oven where the raw material P is expanded to the final bulk and cured.
