Abstract
A device and method for the production of a tubular film in a blown film method with a blown film line. It includes a lay-flat device and a take-off device with a pair of take-off rolls, in which the tubular film can be laid flat, and at least one deaerating device of the previously flattened tubular film. The deaerating device includes a movement device for a cutting device with cutting elements and is arranged in the transport direction of the flattened tubular film downstream of the pair of take-off rolls so that the flattened tubular film can be slit and deaerated by the deaerating device.
