PURPOSE:To automatically perform strong band packing, by integrally mounting upper and lower seal heads forming end sealers to an end seal part along with a machine frame capable of opening and closing with respect to the left and right of a machine and providing a rear stopper and a front stopper to an inlet and providing a press roller and a press plate to an upper part. CONSTITUTION:A corrugated cardboard bundle is arranged, and a front arranging stopper 10 and an upper press apparatus 6 fall to introduce said corrugated cardboard case bundle into an end seal part 2. The corrugated cardboard case bundle fed out from a drive roller conveyor 3 is relieved in pressure by a pre-load press roller 11 and catches two bands stretched in front of said bundle to advance. The corrugated cardboard case bundle fed to a bundling position impinges against a front stopper 20 to stop and a rear stopper 12 falls to hold the corrugated cardboard case bundle between both stoppers to arrange the front and rear thereof. The arranged corrugated cardboard case bundle is compressed by a press plate 22 and the upper and lower seal heads of the end seal part fall and rise to thermally fuse the bands of the rear ends of the case bundle. Two belt conveyors 27 are driven by individual motors and the speeds of the left and right conveyors are synchronized by controlling two motors by one inverter.
