<p>A sheet-binding adhesive coating device provided with a roller (14) which is disposed to be immersed at part thereof in an adhesive (10) stored in an adhesive reservoir (12), and applies, while rolling, the hot-melt adhesive (10) in the reservoir (12) along the arranged one-side edge of a bundle of sheets (54). The device comprises an electromagnetic induction heating coil (20) disposed near the roller (14), and a current supply device (51) for supplying a high-frequency current to the above heating coil (20). The roller (14) is composed of a heating member heated by eddy-current Joule heat by a high-frequency magnetic flux generated by the heating coil (20), and a current supplied to the heating coil (20) by the current supply device (51) heats the roller (14) to melt the adhesive (10) stored in the reservoir (12).</p> |
