An apparatus for shaping plastics material pre-forms into containers includes a blow molding station on a movable conveying device. The station has a blow mold forming a cavity in which the pre-forms are expandable by a gaseous medium. A stressing device acts upon the pre-forms with the gaseous medium to expand them. A clean room surrounds the blow molding station at least in part. A stretching unit stretches the pre-forms along their longitudinal direction and includes a stretch bar movable with respect to the plastics material pre-forms. The stretch bar is insertable into the pre-forms. The station has a receiving space with a wall for receiving the stretch bar, which is movable relative to the receiving space and which surrounds the stretch bar at least in part. A flexible sealing device, which separates a sterile room area from a non-sterile room area, is arranged inside the receiving space.

Apparatus and method of shaping plastics material pre-forms into plastics material containers with stretch bar movement sealed off by rolling diaphragm

At least one blow-molding station is arranged on a conveying device. The blow-molding station includes a blow-mold that forms a cavity into which plastics material pre-forms are expanded by a gaseous medium, supplied by a stressing device. A clean room at least partially surrounds the blow-molding station. A stretching unit stretches the plastics material pre-forms along their longitudinal direction with a stretch bar that is insertable into the plastics material pre-forms. The stretching unit includes a drive device for moving the stretch bar. The blow molding station includes a receiving space with at least one wall for receiving the stretch bar. In operation, the drive device is positioned outside the receiving space at least part of the time. A gaseous medium at a pressure higher than ambient pressure in a non-sterile environment of the receiving space is supplied to the receiving space.

Apparatus and method for shaping plastics material preforms

An apparatus and method for the shaping of plastics material pre-forms into plastics material containers with at least one blow moulding station which is arranged on a conveying device rotatable about a pre-set axis of rotation (D). The blow moulding station has a blow mould and this blow mould forms a cavity in the interior of which the plastics material pre-forms are capable of being expanded by being acted upon with a gaseous medium to form the plastics material containers, with a stressing device, which acts upon the plastics material pre-forms with the gaseous medium in order to expand them, and with a clean room, which surrounds the blow moulding station at least in part. The clean room is bounded off from an environment by at least two walls which are movable relative to one another.
