Abstract
A method for forming plastic parisons to plastic bottles includes the following steps: introducing in a blow mold a plastic parison to be expanded, the blow mold having at least two lateral parts and a base part that is mobile in relation to said lateral parts in a longitudinal direction of the plastic parison; inserting a rod-shaped element in the interior of the plastic parison through a mouth of the plastic parison; applying a first pressure the plastic parison, applying a second pressure to the plastic parison, the second pressure deviating from the first pressure and being higher than the first pressure, applying a third pressure to the plastic parison, the third pressure deviating from the second pressure and being higher than the second pressure. The base part is advanced in the longitudinal direction of the plastic parison while at least temporarily applying the second pressure to the plastic parison.
