A machine for producing containers comprises processing stations with components adaptable to the shape and size of the material sections used for the container. In the case of a change in form, in particular a change in the format of the sections of material to be used, it is necessary to change the relevant adaptable components. Instead of the conventional approach where the new components must be fine-tuned after an exchange has taken place, fitting surfaces are provided at the processing stations, against which a section of the adaptable components can always be placed in the same position. Therefore, time-consuming installation of exchangeable machine components is avoided.
