A bottling apparatus (1) in aseptic conditions of containers (100) made of a thermoplastic material, comprising: at least one mobile organ such as, for example, a blowing nozzle (24) that is partially located in a contamination-controlled environment (3) isolated from an external environment (4); a linear motor (6) for driving the mobile organ (24), the linear motor (6) comprising a cylindrical stator (7) and a rotor or magnetic shaft (8) integrally connected to the mobile organ (24), the separation volume between the rotor (8) and the cylindrical stator (7) being sanitisable by means of a sanitising fluid that passes through a grooved surface (14, 15, 18).

Method for forming plastic preforms into plastic containers, wherein a plastic preform is introduced into a blow mould and is expanded into a plastic container by being applied by a flowable medium, wherein the plastic preform is applied by at least two different pressure levels and wherein furthermore preferably a rod-like body is introduced into the plastic preform, in order to expand the plastic preform in its longitudinal direction, wherein a pressure curve and/or a movement curve of the rod-like body being determined by a measuring device during the expansion process, wherein least one of the curves is evaluated by means of a processor device and at least one point or region of this curve which is characteristic of the course is determined.

The device is used for the blow-molding of containers. A preform made of thermoplastic material, following a thermal conditioning within a blow-mold, is stretched by a stretching rod and is reshaped by effects of blowing pressure into the form of a container. A specification for the positioning of the stretching rod occurs through the use of a linear drive. Blowing pressure is created through the use of at least one positionable blowing gas supply. The linear drive is at least intermittently mechanically coupled with the positionable blowing gas supply and the stretching rod in such a way that coordinated movement kinetics are carried out. The coupling means and the coupled elements are constructed in such a manner that the axis of motion and the resulting force-effect axis form a common spatial axis.

A system for pre-stretching a preform utilized in forming a container. The system including an oven, a conveyor system configured for transporting preforms through the oven a blow molding station having at least one mold with interior surfaces defining the shape of the container, and a transfer station configured to transfer a preform from the oven into the blow molding station. The system also includes a stretch rod and an actuator. The stretch rod is movable between retracted and extended positions such that, when in the extended position, the stretch rod is positioned interiorly of the preform and the preform is elongated by the stretch rod to form a pre-stretched preform. The stretch rod is located to form the pre-stretched preform prior to the blowing medium being introduced into the preform in the blow molding station.
