Abstract:
1. An adhesive coating device comprising: a roller, part of which is immersed in adhesive stored in an adhesive reservoir, for applying the adhesive hot-melted in said adhesive reservoir along an arranged one-side edge of a bundle of sheets while rotating; an electromagnetic induction heating coil disposed in a vicinity of said roller; and a current supply device for supplying a high-frequency current to said electromagnetic induction heating coil, wherein said roller is formed of a heating member for generating heat using a Joule heat owing to an eddy current caused by a high-frequency magnetic flux generated by said electromagnetic induction heating coil, and said current supply device supplies the current to said electromagnetic induction heating coil so as to heat said roller so that the adhesive stored in said adhesive reservoir is melted by said roller.
