    Abstract: An apparatus for shaping plastics material pre-forms into plastics material containers has a conveying device which conveys the plastics material pre-forms along a pre-set conveying path. The conveying device has a movable station carrier arranged at least indirectly on a stationary base carrier and on which a plurality of shaping stations are arranged. The shaping stations have blow moulding devices which form cavities inside which the plastics material preforms are shaped to form plastics material containers. The blow moulding devices are arranged on blow mould carriers. The apparatus has a changing device suitable for removing at least the blow moulding devices from the blow mould carriers and/or arranging blow moulding devices on the blow mould carriers. A changing device has a gripping device for gripping the blow moulding device, wherein this gripping device is movable in at least two different directions and is pivotable about at least three different axes.
