Abstract

The disclosure relates to a deep-drawing apparatus for deep-drawing a continuously fed film web, an associated packaging machine, and a corresponding method. A cyclically sequenced forming station, which runs along from a start position to an end position and runs back from there to the start position is provided, wherein individual format plates are sequentially firstly connected up to a forming vacuum device and then with a following holding vacuum channel. The forming vacuum device is part of the cyclically moved forming station. The holding vacuum channel includes two interlocking telescopic channel portions, a first telescopic channel portion being part of the cyclically moved forming station, and a second telescopic channel portion being mounted statically relative to the fixed machine frame.
