Abstract: A device for forming and pressing a mouth piece of a container comprising fibers, for example pulp, wherein the device comprises a mold for surrounding at least one outer surface of a mouth region of the container in which the mouth piece is to be formed, wherein the mold comprises a structure for forming the mouth piece. The device also comprises a mandrel for introduction into an opening of the mouth region and a movement means for performing a relative movement between the mold and the mandrel to reduce a clearance of the mold and the mandrel, and thus to form and press the mouth piece. This disclosure also includes a method for forming and pressing a mouth piece of a container comprising fibers, for example pulp, using the device.

Abstract: A stretch blow moulding machine and method are provided for forming a container. A preform is expanded to a first configuration in a blow mould of a stretch blow moulding machine. A stretching rod element is introduced to the blow mould to expand the preform from the first configuration to a second configuration. The stretching rod element moves axially in the blow mould in a stretching direction. The plastic perform is temporarily coupled to the stretching rod element during at least a period of time of the expansion of the preform from the first configuration to the second configuration for influencing a behavior of the perform during the expansion.

Abstract: Method for operating an apparatus for forming plastic preforms into plastic containers, wherein in a working mode a plurality of forming stations are moved along a predetermined transport path by a movable carrier, wherein these forming stations in each case having blow mould arrangements which in a closed state in each case form cavities, within which the plastic preforms are formed into the plastic containers and the plastic preforms are supplied to these forming stations in order to be formed by supplying a flowable medium to the plastic containers, wherein this forming takes place at least temporarily during the transport of the forming stations along the transport path, and wherein at least temporarily at least components of the blow moulding arrangement are tempered. At least parts of the blow mould are pre-heated in a standstill of the carrier or a movement of the carrier, which is slower with respect to a movement of the carrier in the working mode.

Abstract: A method is described for shaping the bottom of hot-filled containers, in which the bottoms of the containers are forced inwardly from a state bulged outwardly, in particular as they cool down. Complex mechanisms for forcing the bottom inwardly are dispensable for the reason that the bottoms are forced inwardly by at least one fluid jet and/or fluid pressure wave. In addition, shaping the bottom can advantageously be carried out in a production region immediately downstream of a closer.

Abstract: Disclosed is a method for producing liquid containers by: producing a plastic container by a blow moulding process; filling the plastic container with a flowable medium, such as a liquid; and at least partially closing the container, which is filled with the liquid, with a container closure. After the at least partial closing of the container, a gaseous medium is fed to the interior of the container via at least one opening introduced into at least one portion of a wall of the plastic container or a circumferential wall of the container closure or via an intermediate space which exists between a mouth and the container closure.

Abstract: Provided is a method for operating a device for shaping plastic preforms to form plastic containers, wherein the device has a movable support on which a plurality of shaping stations for shaping plastic preforms to form plastic containers are arranged, and these shaping stations each have blow molds that are suitable for and intended for molding the plastic preforms and are arranged at least indirectly on blow mold supports. The blow molds are kept at least temporarily in a magazine device, wherein this magazine device is suitable for and intended for receiving several sets of blow molds.

Abstract: A method for transforming plastic preforms into plastic bottles, in which preforms are introduced into blowing stations, each blowing station having at least one blow mold and a stretching rod for stretching the preform along a longitudinal axis of the preform within the blow mold, and the preforms are expanded to form the plastic bottles by being acted upon by a gaseous medium in the blow mold, wherein a wall thickness of the plastic container is measured by at least one measuring device which outputs the measured values to a closed-loop and/or open-loop control device, wherein at least a stretching speed of the stretching rod is varied by the closed-loop and/or open-loop control device at least at times and/or at least in some locations during the blowing operation, individually for each blowing station, in order to adjust a wall thickness of the plastic bottles.
