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.
