Abstract
The method and the device are used for blow forming containers of a thermoplastic material. The preforms that are used are first temperature treated and then shaped into containers in the area of at least one blow station. Moulds to define the container shape are held by mould supports. At least two preforms are simultaneously shaped into containers within each blow station. Positioning of the preforms is done such that the preforms assume a positioning relative to one another when entering the blow station that differs from the positioning during the blow forming process. Spacing of the preforms relative to one another is changed during transport between entry into the blow station and blow positioning. In addition to this first change in spacing, a second change in spacing between adjacent preforms is performed relative to one another.
