A deep-drawing arrangement is for deep-drawing a continuously supplied film strip. The deep-drawing arrangement includes a transporter which revolves continuously around a fixed machine frame and which has plate elements and mold cavities and a cyclically timed deep-drawing apparatus, wherein the mold cavities can be acted on with a pressure reduction. The plate elements are permanently connected to each other via connection lines. A plate element is in the form of a connection element having at least one pressure reduction connection. The pressure reduction connection is connected to a pressure reduction source. The plate elements are permanently acted on with the pressure reduction during operation via the connection lines and the pressure reduction connection. Each plate element has at least one switching valve for connecting the pressure reduction which is permanently applied in the plate element to the associated mold cavities as required.

A device () for sealing three-dimensional objects () in the bag opening () of a film bag () comprises a clamp () for the film bag (), which has a pair of clamping shoes () on each side, between which the edge of the film bag () is held. A heat sealer () is provided for sealing the three-dimensional object () in the bag opening () of the film bag (), wherein the heat sealer () has a pair of sealing jaws () between which the bag opening () of the film bag () can be sealed. The two clamping shoe pairs () of the clamp () are moved apart from one another during the sealing process.

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.
