Patent number: 5360874Abstract: A sintered film containing a copolymer and optionally other common additives is described. The film contains about 30 to 70 parts by weight of a propylene copolymer with a melt index MFI 230/2.16 of at least approximately 3 g./10 min. and about 70 to 30 parts by weight of an ethylene-ethyl acrylate copolymer with a melt index MFI 230/2.16 of at least approximately 3 g./10 min. and with a Vicat softening point of at least about 40. The ethylene-ethyl acrylate copolymer contains approximately 7 to 35 wt % of ethyl acrylate. This film exhibits advantageous properties, particularly a good Shore A hardness.Type: GrantFiled: April 28, 1993Date of Patent: November 1, 1994Assignee: J. H.

Patent number: 5262108Abstract: In the course of producing a multicolored slush skin in accordance with the powder-slush method, individual one-piece slush skins are produced in successive process steps, which extend over the entire mold, which is divided into individual color zones by means of separation fins. After the first slush skin with the first color has been produced, the area assigned to another color is cut off and this part taken out of the mold, the other part of the slush skin remaining in the mold. Subsequently a complete second slush skin is formed in the previously emptied partial area as well as in the area of the remaining first slush skin, etc. A multicolored slush skin, looking from the grain side, then is the result after it is finally taken out of the mold, which is distinguished by an exact and visually tidy separating seam between the individual color areas.Type: GrantFiled: September 6, 1991Date of Patent: November 16, 1993Assignee: J. H. Benecke AGInventors: Jurgen Minke, Roland Wolff, Axel Bruder, Werner Wagner

Patent number: 5242750Abstract: A pressure- and vacuum-moldable foam sheeting, consisting of a foam layer, on which is applied a decorative layer, and optionally a primer layer as well as additional layers, for lining the interior of vehicles, is described. It is distinguished owing to the fact that the foam layer has a) a density of approximately 25 to 200 kg/m.sup.3, b) an elongation at break according to DIN 53571 of at least about 50% and c) a compression hardness according to DIN 53577 of at least 50 kPa (at 50% deformation). Preferably, the foam layer consists of a polyolefin. This vacuum-and pressure-moldable foam sheeting does not require any PVC material for its foam layer; disposal problems are thus eliminated. Because of the low weight of the foam sheeting, there is very little rejected material during secondary processing. The foam sheeting is distinguished by good mechanical properties and satisfies the demanding delivery conditions of the automobile industry.Type: GrantFiled: November 19, 1990Date of Patent: September 7, 1993Assignee: J. H. Benecke AGInventors: Werner Wagner, Heinrich Kracke, Gustav Hildebrandt, Reiner Taczkowski, Axel Bruder

Patent number: 5241004Abstract: A sheet or a molded object is described, which is made of a thermoplastic material comprising a polyurethane, a modified polymer and, optionally, conventional additives. This thermoplastic material thus comprises component A in the form of the thermoplastic polyurethane, the polyvinyl acetate in the form of polyvinyl acetate as well as, as flow modifier, the component C in the form of a further thermoplastic material, an elastomer-modified thermoplastic material or a rubber or combinations thereof. This material has about 10 to 35 parts by weight of polyvinyl acetate and about 1 to 50 parts by weight of component C per about 100 parts by weight of component A. The material advantageously shows an improved melt strength. When this material is calendered, no interfering sticking effects occur.Type: GrantFiled: October 1, 1992Date of Patent: August 31, 1993Assignee: J. H. Benecke AGInventor: Walter Kopytko

Patent number: 5034264Abstract: A multilayered polyurethane upholstery material wherein the upper cover layer is designed as a color fast and non-abrasive polyurethane layer with high porosity. Right next to it a foamed lining layer which partially merges into the following layer made of fleece. This fleece layer consists of a fleece impregnated with a binder with suction and storage properties. The highly porous cover layer can let moisture pass through and give it off to the lower fleece layer, so that the cover layer itself remains free.Type: GrantFiled: December 12, 1989Date of Patent: July 23, 1991Assignee: J. H. Benecke AGInventors: Werner Wagner, Axel Bruder, Gustav Hildebrandt

Patent number: 4987029Abstract: A multi-layer arrangement of films which is capable of being deep-drawn including at least an upper and lower film, which is backed by a foam layer, for example, polyurethane foam, for the fabrication of molded objects such as automobile dashboards or similar parts, wherein at least one layer (12, 14) contains particulate pigments which are added during the fabrication of the film and which have essentially no effect on the color of the upper layer (12).Type: GrantFiled: May 9, 1990Date of Patent: January 22, 1991Assignee: J. H. Benecke AGInventors: Werner Wagner, Axel Bruder, Kurt Giehsler

Patent number: 4964197Abstract: To produce non-woven materials, endless filaments in the form of a warp are drawn off a filament draw-off nozzle to which are joined a filament offlet, a filament guide tube and a spreading extruder. An amount of compressed air under high pressure is admitted to the filament draw-off nozzle. By means of the invention the amount of compressed air at the filament draw-off nozzle is reduced and at the same time an additional amount of compressed air under relatively low pressure is admitted between the filament guide tube and the spreading extruder by means of a propelling nozzle. In spite of an additional amount of compressed air at the propelling nozzle the reduction at the filament draw-off nozzle is so large that for the isothermal compression output as a whole a considerable savings in energy of almost 30% can be achieved, and this while maintaining the important filament draw-off force necessary for the drawing of the filaments inside the filament offlet.Type: GrantFiled: April 18, 1989Date of Patent: October 23, 1990Assignee: J.H. Benecke AG and Corovin GmbHInventors: Kurt Mente, Gerhard Knitsch

Patent number: 4818466Abstract: To produce non-woven materials, endless filaments in the form of a warp are drawn off a filament draw-off nozzle to which are joined a filament offlet, a filament guide tube and a spreading extruder. An amount of compressed air under high pressure is admitted to the filament draw-off nozzle, and by means of the spreading extruder provided with Coanda shells the warp is loosened before impacting on a screen conveyor. In order to achieve as evenly as possible a distribution and loosening of the warp, slot nozzles are provided on either side of the spreading extruder, which are supplied with a reduced amount of compressed air under relative low pressure. Simultaneously, a reduction of the amount of compressed air at the filament drawoff nozzle takes place.Type: GrantFiled: November 20, 1986Date of Patent: April 4, 1989Assignees: J. H.

Patent number: 4778375Abstract: In the production of shaped plastic elements using deep-drawable thermoplastic film, a tension frame is required to clamp the film. The tension frame is formed by lengthwise and transverse frame parts, on the outside edges of which is located one angle clamp on each. The angle clamps can be actuated by means of closure levers into a releasable clamping position, in which the clamp arms of the angle clamp press with force against bottom fixing members of the frame parts.Type: GrantFiled: June 23, 1987Date of Patent: October 18, 1988Assignee: J.
