ADHESIVE COATING DEVICE

摘要

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).
