A plastic container manufacturing machine, comprising a chassis having a camway with a cam and a countercam and an element which is movable relative to the chassis, bearing a roller interacting with the camway so as to ensure the displacement of the movable element. The machine also comprising a device for controlling the displacement of the movable element. The countercam has at least one portion which is movable relative to the chassis, and the control device incorporates a distance sensor that continuously measures the distance of a movable portion of the countercam relative to a fixed reference point on the chassis.

Disclosed is a for forming a container with multiple walls by blow molding or stretch blow molding of a preform, including a blow-molding phase followed by a degassing phase, beginning at a moment, of the formed container, to bring t:s pressure back to the ambient pressure. The method also includes: a continuous measurement of the pressure prevailing in the neck during the degassing phase; the determination of the length of time that has elapsed between the beginning of the degassing and the attaining of a reference pressure in the neck; the comparison of the length of time that has elapsed with a theoretical length of time that is necessary so that the reference pressure is attained in the neck; and maintaining the locking of the mold if the length of time that has elapsed is less than the theoretical length of time.

A method for operating a forming device for forming plastic preforms into plastic containers, wherein in a working mode of the apparatus, the plastic preforms are transported by means of a plurality of forming stations along a predefined transport path, and by loading with a fluid medium are expanded into plastic containers, wherein to expand the plastic preforms, blow-moulding devices are used, inside which the plastic preforms are expanded into plastic containers, wherein in a change mode, at least one of the blow-moulding devices is removed from the apparatus and/or one of the blow-moulding devices is arranged on a blow-mould carrier of the apparatus, wherein to change the blow-moulding devices, a change device is used which has a gripper device for gripping the blow-moulding device. According to the invention, in a working mode, the forming device is operated in a first protected area which is not accessible to a machine operator, and the change device is arranged at least partially in a second protected area which is accessible for the machine operator for at least part of the time in working mode, wherein a connection can be created between the first protected area and the second protected area.

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 molding devices which form cavities inside which the plastics material preforms are shaped to form plastics material containers. The blow molding devices are arranged on blow mold carriers. The apparatus has a changing device suitable for removing at least the blow molding devices from the blow mold carriers and/or arranging blow molding devices on the blow mold carriers. A changing device has a gripping device for gripping the blow molding device, wherein this gripping device is movable in at least two different directions and is pivotable about at least three different axes.
