Patent number: 11708931Abstract: The invention relates to a tubular liner for the rehabilitation of an, in particular, underground sewer pipe, comprising at least an inner tubular film, a resin-carrier layer surrounding the inner tubular film, and comprising a mechanically protective outer film system. The outer film system comprises at least one outer film in the form of a UV-radiation- and short-wavelength, visible light-absorbing and/or -reflecting, single-layer or multi-layer film which contains, in one or more polymer layers, at least one short-wavelength, visible light-absorbing and/or—reflecting, organic or inorganic color pigment or a corresponding dye, and at least one organic or inorganic compound which absorbs and/or reflects the UV radiation. Moreover, the outer film system comprises at least one mechanically stable reinforcing web which rests on the aforementioned outer film. The outer film system has a transmittance for visible light at at least one wavelength in the range of 550 nm to 800 nm of at least 1%.Type: GrantFiled: August 30, 2021Date of Patent: July 25, 2023Assignee: BUERGOFOL GMBHInventor: Kurt Stark

Patent number: 11319097Abstract: A novel lower tool enables a packaging machine having a molding station with a trough to be used to produce skin packaging having a flat base plate. The lower tool includes a body base and a flat upper surface and is arranged in the molding station of the packaging machine such that the flat upper surface of the lower tool covers the trough. The lower tool fits detachably into a lower tool holder of the packaging machine. During the packaging production, the flat upper surface supports the flat base plate of the packaging. Suction applied via a passage through the flat upper surface is used to hold the flat base plate onto the flat upper surface. The lower tool is a means for converting the packaging machine from producing a first type of packaging having a trough-shaped carrier into producing a second type of packaging that has a flat carrier.Type: GrantFiled: February 10, 2020Date of Patent: May 3, 2022Assignee: Buergofol GmbHInventor: Christian Huber

Patent number: 11105455Abstract: The invention relates to a tubular liner for the rehabilitation of an, in particular, underground sewer pipe, comprising at least an inner tubular film, a resin-carrier layer surrounding the inner tubular film, and comprising a mechanically protective outer film system. The outer film system comprises at least one outer film in the form of a UV-radiation- and short-wavelength, visible light-absorbing and/or -reflecting, single-layer or multi-layer film which contains, in one or more polymer layers, at least one short-wavelength, visible light-absorbing and/or -reflecting, organic or inorganic color pigment or a corresponding dye, and at least one organic or inorganic compound which absorbs and/or reflects the UV radiation. Moreover, the outer film system comprises at least one mechanically stable reinforcing web which rests on the aforementioned outer film. The outer film system has a transmittance for visible light at at least one wavelength in the range of 550 nm to 800 nm of at least 1%.Type: GrantFiled: March 20, 2019Date of Patent: August 31, 2021Assignee: Buergofol GmbHInventor: Kurt Stark

Patent number: 10040935Abstract: A single or multilayered film is presented having at least one layer that contains at least one thermoplastic olefin homo or copolymer, modified if need be. The layer contains additionally, at least one polyester. Such film is used as a sliding film or preliner in trenchless pipe renovation using the tube lining technique in which the film is layed on the inner wall of an underground sewer pipe laid that will be renovated. An insertion pipe with a curable carrier material can be pulled in sliding fashion over the sliding film laid on the pipe.Type: GrantFiled: August 17, 2017Date of Patent: August 7, 2018Assignee: BUERGOFOL GMBHInventors: Abdel-Kader Boutrid, Kurt Stark, Franz Schleicher, Gregor Schleicher

Patent number: 9731488Abstract: The invention refers to a method for laminating a tubular film (1) preferably manufactured by means of blown film (co-) extrusion with a material capable of absorbing resin or liquids, wherein the tubular film (1) is laminated over its entire perimeter with several layers (10, 11, 12, 13; 20, 21, 22; 30, 31) overlapping or positioned directly opposite one another on their front sides containing material capable of absorbing resin or liquids, so that essentially there are no areas left along the perimeter of the tubular film (1) not covered by the laminated layers (10, 11, 12, 13; 20, 21, 22; 30, 31). The invention also refers to a tubular film laminated in such a way and to various applications.Type: GrantFiled: April 7, 2014Date of Patent: August 15, 2017Assignee: Buergofol GmbHInventor: Kurt Stark

Patent number: 9656438Abstract: A multi-layered film in the form of a hose-shaped outer film for an insert hose of a pipe rehabilitation system includes silver-colored pigments in at least two layers of the film, or a metallization applied on both outer layers of the film, or silver-colored pigments in at least one layer of the film and a metallization is applied on an outer layer of the film. At least one UV absorber is inserted in at least one or several layers of the film of the film. The entire film is permeable to UV light and visible light in a wavelength range from 200 to 800 nm at a rate of less than 0.1%, and is opaque. The UV radiation and visible radiation are reflected in a wavelength range from 200 to 800 nm.Type: GrantFiled: December 9, 2014Date of Patent: May 23, 2017Assignee: BUERGOFOL GMBHInventor: Kurt Stark
