Publication number: 20080193582Abstract: The invention relates to an extrusion storage head (10) for a blow-molding machine and a method for production of blow-molded multi-layer plastic hollow bodies made from a two- or multi-layer pre-form, whereby two or more peripheral manifolds (16, 18) are arranged above a storage reservoir (20), from which the peripherally-extruded plastic may be sequentially ejected as a tubular parison from a controlled annular nozzle (24) by means of an ejector piston (22). According to the invention, an additional peripheral manifold (26) is arranged between the storage chamber (20) and the controlled annular nozzle (24) for application of a further plastic layer (outer functional layer) on the previously peripherally extruded plastic carrier. The additional peripheral manifold (26) is connected through a supply line (28) to an additional external storage element (30) for the molten plastic of the functional layer, wherein the additional external storage element (30) has a separate extruder (32).Type: ApplicationFiled: May 5, 2006Publication date: August 14, 2008Applicant: Mauser-Werke GmbHInventor: Peter Langos

Patent number: 6923636Abstract: A blow-molding machine for producing blow-molded hollow bodies from a thermoplastic material, includes two blow-mold halves which can be horizontally displaced and provided with separate drive units for a transport drive and for the sequence of movements of the mold closing and locking device to open and close the blow mold halves. Conventional blow-molding machines are still equipped with hydraulic drives at least for the mold closing and locking device. In order to provide a blow-molding machine that can for example be operated under clean-room conditions, the drive unit of the blow-molding machine according to the invention is configured for the clamping elements of the mold closing and locking device as an electromotive direct drive with a spindle drive and a spindle mechanism with recirculating rollers.Type: GrantFiled: May 13, 2002Date of Patent: August 2, 2005Assignees: Mauser-Werke GmbH & Co. KG, Kautex Maschinenbau GmbHInventors: Peter Langos, Wolfgang Hamlischer, Johannes Geilen, Markus Holbach, Wolfgang Schmitt, Erich Kiefer, Karsten Friedrichs, Olaf Weiland

Patent number: 6773249Abstract: The invention relates to an extrusion head for producing a tubular parison (22) in order to manufacture large-volume, blow molded plastic hollow bodies. The inventive extrusion head has an adjustable ring-shaped tube outlet nozzle for selectively adjusting the nozzle opening (20) in order to alter the wall thickness of the exiting parison (22). In order to provide a multiple adjustability of the extruded tube cross section, the invention provides that the extrusion head comprises at least three separate nozzle/mandrel gap adjustment elements (D 0=mandrel, DS I, DS II, DS III) which are differently profiled and exchangeable. The elements can be individually and/or simultaneously brought into working contact with the exiting parison (22) in the mandrel gap (20) from inside and/or outside, whereby at least two of the adjustment elements (D 0=mandrel, DS I, DS II, DS III) are configured such that they can be adjusted.Type: GrantFiled: September 5, 2000Date of Patent: August 10, 2004Assignee: Mauser-Werke GmbHInventors: Dietmar Przytulla, Peter Langos

Patent number: 6551089Abstract: The invention relates to an extrusion head (10) for a blow molding machine for producing two-layered hollow plastic bodies, including one or more extruders, connected to the extrusion head housing (12), for supply of molten plastic melt. In particular when using different plastic materials of different viscosities, it is very important to create for both materials substantially the same rheological flow conditions when distributed across the circumference to form a tubular parison.Type: GrantFiled: January 17, 2001Date of Patent: April 22, 2003Inventors: Peter Langos, Manfred Lehmann, Stefan Keusch

Patent number: 5975881Abstract: A blow molding machine, includes a base frame, a blow mold adapted for receiving a tubular parison and having a first mold support plate for support one mold half and a second mold support plate for support of another mold half. A transport unit is mounted to the base frame for so moving the first and second support plates that the mold halves are free from any direct, form-fitting coupling, with the transport unit including a first drive mechanism operatively connected to the first support plate and a second drive mechanism operatively connected to the second support plate and operating independent of the first drive mechanism. Secured to the support plates is a locking mechanism for pinching off the tubular parison and clamping the mold halves during the blow molding operation.Type: GrantFiled: November 14, 1997Date of Patent: November 2, 1999Assignee: Mauser-Werke GmbHInventors: Peter Langos, Wolfgang Hackner, Wolfgang Hamlischer, Uwe Humrich, Klaus Maier

Patent number: 5562934Abstract: A blow molding machine designed as a two station machine (10) has at least one extrusion device (12) and an accumulator head which supplies a tubular thermoplastic parison to two blow molds arranged next to each other and having two horizontally movable blow molding halves. In order to simplify the construction of the machine at reduced space and to achieve a high productivity, the blow molding machine according to the invention has only a three-platen system with three mold mounting plates (22, 24, 26) for clamping the four blow molding halves (14, 16, 18, 20).Type: GrantFiled: September 22, 1994Date of Patent: October 8, 1996Assignee: Mauser-Werke GmbHInventors: Peter Langos, Uwe Humrich

Patent number: 5460504Abstract: The invention relates to a storage head for a blow moulding machine for discontinuous manufacture of multi-layer co-extruded and blow-moulded hollow bodies made of thermoplastic. To improve the product quality and to increase the throughput, each distributor element is designed as a spiral channel distributor (20) which distributes the individual molten plastic streams uniformly at the periphery. The ejector (14) consists of at least two concentric tubular pieces (42, 44) and the peripherally distributed plastic flows from the ejector (14) through an annular gap (46) into the storage space (16) in the storage head housing (10) below the ejector.Type: GrantFiled: August 20, 1993Date of Patent: October 24, 1995Assignee: Mauser-Werke GmbHInventors: Peter Langos, Manfred Lehmann
