20090278288 | Method and Device for Blow-Molding Containers - The invention relates to a method and a device for blow-moulding containers. Following a thermal conditioning process, a parison is stretched by a horizontal bar inside a blow station provided with a blow mould, and is moulded into a container by the effect of the blowing pressure. In order to carry out the blow-moulding, pressurised gas is introduced into the container. The horizontal rod is hollow at least in parts. Once a maximum blowing pressure has been reached in the blow station and at the earliest at the beginning of a pressure drop, a cooling gas is guided out of the horizontal bar towards the bottom of the blown container. | 11-12-2009 |

20100001439 | AUXILIARY DEVICE AND METHOD FOR FINISHING PREFORMS - An auxiliary device and a method for finishing and calibrating preforms that are removed from a multiple tool in an unstable shape, the calibration process being performed with compressed air immediately after removing and withdrawing the preforms from the multiple tool. Nipples that can be inserted into the preforms are provided with expandable press rings or sealing rings in order to seal the interior of the blow-molded part of the preforms. The compressed air is introduced via the nipples, the sealing process being performed by radially expanding the press rings or sealing rings in analogy to the closing process of thermoses, thus protecting the preforms from adverse forces. The sealing point can be randomly selected in the transition zone from the threaded part to the blow-molded part of the preforms. The interior of the blow-molded part is optimally sealed without affecting the form stability and dimensional stability of the preforms. | 01-07-2010 |

20100072679 | Container Made From Expanded Plastic Film - A plastic film preform is expanded to form a container. The preform has a longitudinal axis that extends from an open top to a closed bottom. The preform is pressurized with a first pressure sufficient to cause side walls of the preform to expand outwardly and the bottom of the preform to be drawn inwardly thereby reducing a length of the preform along the longitudinal axis. Side molds are closed around the side walls of the preform, the closed side molds being larger than the expanded side walls. A bottom mold is closed to be adjacent to the bottom of the preform after pressurizing the preform with the first pressure. The preform is pressurized with a second pressure sufficient to expand the preform to fill the closed molds. The preform is thereby significantly stretched in a direction perpendicular to the longitudinal axis and minimally stretched along the longitudinal axis. | 03-25-2010 |
