Method of seaming carpet

A method for joining two carpet segments, each carpet segment having an underside and at least one edge, comprises abutting one edge of one carpet segment with one edge of the other carpet segment, positioning a length of seam tape under the abutting edges, and activating the adhesive to secure the seam tape to the undersides of both carpet segments. The seam tape comprises an elongated base layer being resilient in a longitudinal direction, an intervening layer applied to the base layer, and an adhesive applied to the intervening layer.

Composite live hinge

A hinged component includes first and second portions of material coupled together by a composite live hinge. The live hinge includes a layer of tensile fabric and a layer of elastomer interposed between the tensile fabric and the material of one or both of the coupled first and second portions. The composite live hinge is capable of joining structural composite materials without the need for scoring, and thereby weakening, the structural composite material along the desired hinge line. The live hinge can be embedded in the materials it joins in a method that is compatible with traditional structural composite layup processes and in a manner which prevents resin from the structural composite materials from infiltrating the tensile fabric and compromising its flexibility.

20190270257 · 2019-09-05 ·

Described is a heating means for thermally connecting two objects each having a plastic material, wherein, during the connecting, a first inner object is surrounded at least partially by a second outer object, and the heating means surrounds the first inner object at least partially along a complete circumferential course around the first inner object, and is located between the first inner object and the second outer object. The heating means has a ribbon-type structure. The ribbon-type structure has an auxiliary heating material, which is inductively heatable, wherein the auxiliary heating material is spatially distributed or arranged along the circumferential course such that an electrical conductivity is interrupted at at least one position along the complete circumferential course around the first inner object. Further described are an arrangement and a system each having such a heating means as well as a method for thermally connecting two plastic objects.

ENHANCED COMPOSITE LIVE HINGE
20190264482 · 2019-08-29 ·

A hinged component fabrication method in which, in a layup stage of fabrication, the component includes a live hinge joining uncured material portions together at a hinge region and comprising a layer of tensile fabric at least partially infiltrated by an uncured elastomer layer at least partially interposed between the tensile fabric and the uncured material portions such that the uncured elastomer blocks the uncured material portions from infiltrating the hinge region. The method may include locating overlapped tensile fabric and elastomer layers in a tool and introducing polymer-based material into the tool such that polymer-based material portions overlap respective opposite ends of the fabric and elastomer layers. The polymer-based material portions are formed to a desired shape using the forming tool so that the fabric and elastomer layers form a live hinge between the polymer-based material portions.

PRESSURELESS BONDING PROCESS FOR ATTACHING SOLAR CELLS TO A PANEL
20190267934 · 2019-08-29 ·

A method for forming a solar panel can include attaching one or more tacking pads to one or both of a first surface of a first solar panel subassembly and a second surface of a second solar panel subassembly. The method further includes dispensing an adhesive onto at least one of the first and second surfaces. The first and second surfaces are placed in contact with the one or more tacking pads, thereby tacking the first and second solar panel subassemblies together, during which the first and second surfaces contact the adhesive, thereby decreasing a thickness and increasing a surface area of the adhesive. Subsequently, the adhesive is cured. The tacking pad(s) maintain fixed alignment of the solar panel subassemblies during curing of the adhesive, and establish a bond line of the adhesive.
