Publication number: 20100013125Abstract: The invention relates to a device and a method for finishing and calibrating preforms (10) which are removed from a multiple injection tool in an unstable shape, and proposes an air cooler integrated into the water cooled cooling sleeves (21) for the outer side of the open end face of the preform (10). Particularly in the case of special preform varieties, the areas which are unsupported in the cooling sleeves (21) can be pre-strengthened on the outside, from the beginning of the transfer from the open molds (8, 9) to the removing and cooling sleeves, respectively, by means of a cooling which uses cooling air or low-temperature air. With the novel solution, the highest quality can be assured, in particular with respect to dimensional stability and the absence of pressure points under load, by means of a calibration in the cooling sleeves (32) and the treatment in the area of the aftercooling.Type: ApplicationFiled: January 25, 2008Publication date: January 21, 2010Applicant: Netstal-Maschinen AGInventor: STEFAN BOCK

Patent number: 7611660Abstract: The present invention relates to an apparatus and method for cooling material during continuous vacuum forming. The apparatus includes one or more cooling regions positioned adjacent one or more vacuum regions. A rotatable support belt including perforations therein supports a flexible patterned belt. The flexible patterned belt includes apertures spaced along the length and width thereof. The one or more cooling regions provide a cooling fluid to be drawn through the apertures in the flexible patterned belt to form an area of cooling fluid on the flexible patterned belt which contacts a bottom surface of a hot material received on the flexible patterned belt in order to cool the bottom surface of the material and the flexible patterned belt. The vacuum regions are in fluid flow communication with the perforations of the support belt and the apertures of the flexible patterned belt for drawing the material onto the flexible patterned belt.Type: GrantFiled: July 18, 2006Date of Patent: November 3, 2009Assignee: Bosler Design Services, Inc.Inventor: Kenneth D.

Patent number: 7485252Abstract: Apparatus and method for making a molded plastic article having a stretched and crystallized neck finish. In one embodiment, a series of platforms are carried by a conveying apparatus for transporting a series of molded plastic articles along a predetermined path of travel through one or more treatment stations. At a finish widening station, the molded article, having a relatively wide and thin-walled blow-molded body portion, and a relatively narrow and thick-walled unexpanded neck finish portion, is positioned to enable insertion of a mandrel into an open top aperture of the finish portion to widen the finish. The mandrel may include a lower heated tapered portion for expanding the finish, and an upper cooled body portion on which the expanded finish may be cooled. The article may then be sent to a finish crystallizing station having a heating device that heats the widened finish portion for a time and temperature selected to crystallize at least a portion of the widened finish.Type: GrantFiled: September 6, 2006Date of Patent: February 3, 2009Assignee: Graham Packaging Company, LPInventors: Keith Barker, Brian Lynch, Thomas E.

Patent number: 7402268Abstract: A process for manufacturing a composite profile based on a thermoplastic organic material reinforced by reinforcing fibres includes making a multiplicity of continuous reinforcing yarns come into contact with a thermoplastic organic material and shaping the composite profile. Continuous yarns based on continuous glass fibres and on a first thermoplastic are brought together to be parallel and at least one consolidated tape is formed by heating them, in which tape the reinforcing fibres are impregnated with the first thermoplastic. The at least one tape is introduced into a die sized to the cross-section of the profile and at least one second molten thermoplastic organic material is simultaneously introduced into the die in contact with the tape, to obtain a profile of at least one second thermoplastic organic material reinforced by the at least one tape.Type: GrantFiled: April 25, 2001Date of Patent: July 22, 2008Assignee: OCV Intellectual Capital, LLCInventors: Philippe Boissonnat, Edward Cooper, Guy Zanella, Remi Carel, Philippe Macquart, Thierry Gay
