METHOD OF PRODUCING WALLPAPER

The present invention relates to a foamed embossed silk wallpaper production apparatus having a multi-stage foam with a near-infrared heating hot air oven. To this end, the foamed embossed silk wallpaper production apparatus comprises: a wallpaper supply part; a first coater and a second coater; a first near-infrared heating hot air oven and a second near-infrared heating hot air oven consisting of hot air of a hot air fan and a near-infrared lamp; a surface processing device; and a wallpaper winding part. A polyvinyl chloride (PVC) plastisol layer is formed on an upper side of the paper wallpaper to have two or more stages, and near-infrared ray and hot air are simultaneously generated and heated in the near-infrared heating hot air oven. By forming two or more stages of foam layers are rapidly and stably formed on the upper surface of the wallpaper paper so that three-dimensional patterns are clearly and smoothly formed on the surface thereof, thereby enabling mass-production of wallpaper having two or more stages of foam layers. 본 발명은 벽지공급부와, 제1,2코팅기와, 근적외선램프와 열풍기의 열풍으로 구성된 제1,2근적외선가열열풍오븐기와, 표면가공기와, 벽지권취부로 구성하여 벽지원지의 상부면에 PVC플라스티졸층을 2단 또는 2단이상으로 형성하여 근적외선가열열풍오븐기에서 근적외선 및 열풍을 동시에 발생가열하여 벽지원지의 상부면에 2단 또는 2단이상의 발포층을 신속하고 안정적으로 형성하여 그 표면에 입체적무늬를 선명하고 양호하게 형성하고, 2단 또는 2단이상의 발포층을 갖는 벽지를 대량으로 생산하도록 한 근적외선가열열풍오븐기를 구비한 다단발포체를 갖는 발포 엠보실크벽지제조장치에 관한 것이다.
