PURPOSE:To enable the attainment of uniform baking quality and to improve the operation efficiency of a baking furnace, by applying continuous varnish baking to a hooped material while uncoiling the material before cutting an electromagnetic steel plate. CONSTITUTION:After being set on an uncoiler 8, a hooped material is uncoiled and simultaneously subjected to varnish coating by a varnish roller 2, and then it is conveyed by a conveyor 5 into a baking furnace 4, wherein varnish baking is applied thereto. An electromagnetic steel plate 6a undergoing the varnish processing is coiled on a recoiler 9 and a continuous operation is started. The speed of these recoiler 9 and uncoiler 8 is changed synchronously with that of the varnish roller 2 and the conveyor 5. The speed of rotations of the varnish roller 2 and the conveyor 5 and a furnace temperature 3 are adjusted automatically to be proper based on the baking quality which is detected by a baking quality detecting device 7 set on the recoiler 9 side. A series of operations described above are controlled automatically. |
