| 摘要 |
The present invention relates to an adhesive coating device for sheet-binding provided with a roller 14, part of which is immersed in adhesive 10 stored in an adhesive reservoir 12, for applying hot-melted adhesive 10 in the above-mentioned adhesive reservoir 12 along the arranged one-side edge of a bundle of sheets 54 while rotating. The device includes an electromagnetic induction heating coil 20 disposed in the vicinity of the above-mentioned roller 14, and a current supply device 51 for supplying a high-frequency current to the above-mentioned electromagnetic induction heating coil 20. The above-mentioned roller 14 is formed of a heating member for generating heat using the Joule heat owing to an eddy current caused by a high-frequency magnetic flux generated by the above-mentioned electromagnetic induction heating coil 20, and the above-mentioned roller 14 is heated by supplying a current from the above-mentioned current supply device 51 to the above-mentioned electromagnetic induction heating coil 20 so that the adhesive 10 stored in the above-mentioned adhesive reservoir 12 is melted. |
