Patent number: 5576034Abstract: In an apparatus for the production of hollow bodies from thermoplastic material by use of extrusion blow molding, having at least two blow molding units and an extrusion system, in an operating cycle each blow molding unit is movable between a receiving position in which the opened blow molding mold receives a preform and at least one other position in which the expanded hollow body is removed from the blow molding mold. Each blow molding unit is firstly moved from a station remote from the removal station in at least one direction into the removal station and opened after reaching the removal station, whereupon the hollow body previously produced in the blow molding mold is removed. The respective blow molding unit is then moved by use of a second movement in another direction, with the blow molding mold open, into the receiving position which is arranged laterally displaced relative to the path of movement along which the blow molding unit is moved into the removal station.Type: GrantFiled: February 3, 1995Date of Patent: November 19, 1996Assignee: Krupp Kautex Maschinenbau GmbHInventors: Erich Kiefer, Karsten Friedrichs, Klaus Baltes

Patent number: 5368462Abstract: An apparatus for the production of hollow bodies from thermoplastic material by blow molding using a blow molding mold which includes at least first and second mold portions to enclose a generally tubular extruded preform which is expanded within the mold under the effect of an increased internal pressure within the preform. To provide for asymmetric closing and/or opening movements of the mold portions relative to the preform, the blow molding mold is displaced as an entirety parallel to the direction of the opening and/or closing movements of the mold portions, more especially during the mold closing and/or opening procedure, so that an additional motion is superimposed on the movements of the mold portions.Type: GrantFiled: September 30, 1993Date of Patent: November 29, 1994Assignee: Krupp Kautex Maschinenban GmbHInventors: Erich Kiefer, Peter Klusener, Karsten Friedrichs

Patent number: 5143681Abstract: In a process and apparatus for the discontinuous production of preforms for producing hollow bodies from thermoplastic material, the wall of which is a laminate having at least first and second layers, by extrusion blow molding, the flow of material for forming the laminate is guided within the extrusion head which serves to produce the preforms, by suitable dimensioning of the volume of the duct system accommodating the laminate, such that regions of disturbed laminate occur in the end portions of the preform which are squeezed off the extruded preform by the blow molding mold as a waste portion.Type: GrantFiled: March 15, 1991Date of Patent: September 1, 1992Assignee: Krupp Kautex Maschinenbak GmbHInventors: Werner Daubenbuchel, Otto Eiselen, Karsten Friedrichs, Erich Kiefer, Peter Klusener

Patent number: 5141698Abstract: In a process and apparatus for the production of hollow bodies from thermoplastic material, having a wall of a laminate formed by at least first and second layers, by means of extrusion blow molding, a preform having a wall structure with a suitable number of layers is first produced in a batch-wise procedure using an extrusion head. The material required to produce the preform is guided in the extrusion head in such a way that disturbed portions of the laminate pass into the waste flash portions at the ends of the hollow body produced from the preform, so that the wall of the finished hollow body is devoid of disturbed laminate portions of that kind.Type: GrantFiled: March 15, 1991Date of Patent: August 25, 1992Assignee: Krupp Kautex Maschinenbau GmbHInventors: Werner Daubenbuchel, Otto Eiselen, Karsten Friedrichs, Erich Kiefer, Peter Klusener

Patent number: 5110519Abstract: In a process and apparatus for the production of hollow bodies from thermoplastic material, the walls of the hollow bodies are of a laminate structure having at least first and second layers, by means of extrusion blow molding, the pressure within the extrusion head and more particularly at the location at which the laminate is formed by the discharge of flows of material from a storage chamber in the head is maintained within limits such as to avoid disturbing the laminate to such an extent as to have an adverse effect on its function. The pressure at the time of a transition between filling and emptying of the storage chamber and between emptying and filling of the storage chamber is maintained substantially at a pressure level which approximately corresponds to the storage chamber emptying pressure.Type: GrantFiled: July 9, 1990Date of Patent: May 5, 1992Assignee: Krupp Kautex Maschinenbau GmbHInventors: Werner Daubenbuchel, Otto Eiselen, Karsten Friedrichs, Dieter Hess, Erich Kiefer, Peter Klusener
