APPARATUS AND METHOD FOR FORMING PLASTICS PREFORMS WITH CONTROLLED VALVE UNIT
A method for forming plastic preforms into plastic containers, wherein the plastic preforms being transported along a predetermined transport path and being acted upon and expanded by a flowable medium during this transport, a controllable valve of a reducing station controlling the action of the flowable medium on a compressed-air reservoir, in particular an annular channel, and a desired target pressure being predetermined, with which the compressed-air reservoir is acted upon, this desired target pressure being taken into account in the control of the valve of the reducing station wherein an actual pressure is determined and this actual pressure is compared with the desired target pressure and, from this comparison, a correction value is determined which is taken into account and/or used in the control of the valve.
Apparatus and process for aseptically forming containers starting from parisons made of a thermoplastic material
Process for aseptically forming containers (100) starting from parisons made of thermoplastic material, comprising the steps of: injecting sterile compressed air inside a parison arranged in a stretch-blowing forming mould (2) so as to obtain a container (100); evacuating the exhaust compressed air from the formed container (100); making at least a part of the exhaust compressed air evacuated from the formed container (100) passing through a sterile filter (SF) so as to obtain recovery sterile air; injecting the recovery sterile air in another parison arranged in another forming mould (2).

METHOD FOR THE PRODUCTION OF FILLED CONTAINERS FROM THERMALLY CONDITIONED PREFORMS
A method for producing containers filled with liquid content from preforms made of thermoplastic material. The liquid content is fed as a pressure medium into thermally conditioned preforms during a forming and filling phase in a mold of one of a plurality of forming stations arranged circumferentially spaced apart on a common, continuously rotationally driven working wheel. A compensating device compensates for thermal consequences of centrifugal force acting on the liquid content fed into the preform during the forming and filling phase. The compensating device imparts a temperature profile to the preform in a circumferential direction, which is not point-symmetrical in relation to a longitudinal axis of the preform to produce a thermally differentiated partial circumferential region. The preform is inserted into the mold such that the thermally differentiated partial circumferential region faces in a radial direction of the working wheel.

System and method for forming containers using blow mold and electric heating elements
A system for forming a container includes an injection station configured to inject a liquid material into a mold to form a preform. The system also includes a forming station including an apparatus for forming a container. The apparatus includes a blow mold configured to receive the preform and inject air into the preform to form the container. The blow mold includes an inner mold surface. The apparatus also includes at least one stretching rod configured to contact the preform in the blow mold and stretch the preform. The apparatus further includes electric heating elements coupled to the blow mold and positioned adjacent the inner mold surface to heat the inner mold surface. The system further includes a removal station configured to release the container from the system.
METHOD FOR ANGULAR INDEXING OF A PREFORM
A process for angular indexing of a pre-form having a body and a neck. The process includes a step of marking the neck of the pre-form which consists of production of at least one reference point on the neck of the pre-form. The process also includes a step of a heating station taking charge of the pre-form, during which the pre-form is transported along a heating course by a support unit, known as a spinner, which makes it possible to turn the pre-form around its axis, and during which the body of the pre-form is heated. The marking step is carried out during the step of taking charge, when the pre-form, supported by a spinner, travels along the heating course.
Sterile blow-moulding machine with ejection for containers
An apparatus for forming plastic preforms into plastic containers, with a movable carrier on which at least one forming station is arranged for forming the plastic preforms, wherein the forming station is transported along a predefined transport path, and wherein the apparatus has a clean room inside which the plastic preforms are formed, wherein this clean room is isolated from a non-sterile environment by at least one wall, with a sterilisation device for sterilising the plastic preforms and/or plastic containers, which device acts upon the plastic preforms and/or plastic containers to be sterilised with a flowable sterilisation medium for their sterilisation. According to the invention, the apparatus comprises an ejection device for ejecting containers from the clean room, and this ejection device has a lock chamber from which the ejected containers can be removed, wherein this lock chamber can be acted upon with an atmosphere containing a sterilisation medium.
