<p>The present invention relates to an apparatus for automatically applying water glue. According to the apparatus for automatically applying water glue of the present invention, for a papering work using a floating technique, glue is automatically applied to the upper end and lower end of the wallpaper as well as the both sides of the wallpaper and water is evenly applied to the middle portion of the wall paper, where glue is not applied. To this end, a glue blocking roller (40) selectively adheres to a glue-applying roller (35); the glue blocking unit (45) removes glue while adhering closely to the outer surface of the glue-applying roller (35), thereby avoiding delivering glue to the upper part of the glue-applying roller (35) to prevent the middle portion of a wallpaper (P) passed through the glue-applying roller (35) from being coated with glue. Instead, water is applied to the middle portion of the wallpaper (P), where glue is not applied, by a water film formed on the outer surface of the water-applying roller (60). According to the present invention, papering workability is improved, papering quality is enhanced, and labor and costs are saved.</p> |
