    Abstract: A method for forming plastic preforms into plastic bottles includes introducing a plastic preform to be expanded into a blow mould, wherein this blow mould has at least two side parts and a bottom part which is movable in a longitudinal direction of the plastic preform in relation to these side parts; introducing a rod-shaped body through a mouth of the plastic preform into the interior of the plastic preform; applying a first pressure to the plastic preform; applying a second pressure to the plastic preform, wherein this second pressure differs from the first pressure and is higher than the first pressure; applying a third pressure to the plastic preform, wherein this third pressure differs from the second pressure and is higher than the second pressure. After applying the third pressure to the plastic preform, the bottom part is moved in the longitudinal direction of the plastic preform towards the latter.
