<p>The machine has a base part (3) for forming a base of a stationary container part (1), and a gap (4) formed between the base part and the container part. A gap width adjusting device (10) changes width of the gap and has a compression element (11) surrounding a section of an external circumference of the container part. Wall thickness and/or material of the container part in an area surrounded by the compression element are selected such that cross section of the container part is reversibly reduced by compressing the compression element.</p> |
