Abstract

The device serves to apply a prestress to blow moulding elements mounted in the region of mould carriers. The blow moulding elements am adjacent to each other in the area of a mould seam and in each case regionally enclose an internal space, which is intended for shaping a container manufactured with a blow process. In an elastomer a positioning element is embedded at least regionally and is enclosed at a distance by a peripheral element. At least part of the elastomer is arranged between the peripheral element and the positioning element in order to form an elastic connection.
