Abstract
The device for the roll-sealing of sheets has a mating roll and a sealing roll, which presses against the mating roll with a sealing force, so that a molded sheet and a cover sheet can be guided between the sealing roll and the mating roll and sealed to form a sealed composite sheet structure. The surface of the mating roll has recesses to accept blister pockets of the molded sheet and a rippled structure. The elevations formed by the rippled structure comprise contact areas of different sizes.
