Abstract
An apparatus and a method are for sealing packages on a flatbed machine. The package is formed from a base-film web and a water-soluble cover-film web. The sealing apparatus includes a liquid supply, at least one moistening unit, and a pressing device for vertically pressing and sealing the cover-film web together with the base-film web. The moistening unit has a moistening roller and a spraying device, the moistening unit being able to be switched between a first operating state and a second operating state. In the first operating state, the moistening roller acts on the cover-film web at a roller moistening location. During or after a machine standstill period, the sealing apparatus is transferred to a second operating state in which the spraying device acts on a spray portion of the cover-film web. The spray portion lies between the roller moistening location and the sealing location in the feed region.
