Abstract
The invention is concerned with a new way of packaging film, e.g. plastics film. The film is packaged as a concertina pack. This is done by combining the effects of gas blowers and movable feet. A fold is started by one set of blowers and completed by an opposed set of feet. The next fold is then started by the opposite set of blowers and its corresponding opposed set of feet, and this sequence is repeated until the pack is completed.
