An elongated device to seal an edge of a substrate has an elongated flexible linear form capable of rolling, akin to a tape. The tape has its own substrate encapsulated by a polyurethane coating. Upon application of heat, the tape welds to a base layer of a fabric, such as nylon. The tape continuously merges into the base and thus prevents intrusion of fluids and gasses through any stitching or other apertures of the base, including any pathogens, microbes, and viruses in the fluids and gasses. The tape resists over forty washings of the conjoined base part of a garment made from the fabric. The tape has proportions that promote a tight seal of the base and comfortable feel to the skin of a wearer of a garment having the tape upon the fabric.

A method for surface preparation of composite substrates prior to adhesive bonding. A curable surface treatment layer is applied onto a curable, resin-based composite substrate, followed by co-curing. After co-curing, the composite substrate is fully cured but the surface treatment layer remains partially cured. The surface treatment layer may be a resin film or a removal peel ply composed of resin-impregnated fabric. After surface preparation, the composite substrate is provided with a chemically-active, bondable surface that can be adhesively bonded to another composite substrate to form a covalently-bonded structure.

A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.

There is described a method for forming a tube (3) of a web (4, 4) of packaging material comprising the steps of advancing the web (4) of packaging material along a web advancement path (P), overlapping a first lateral edge (19) of the web (4, 4′) of packaging material with a second lateral edge (20) of the web (4, 4) of packaging material for obtaining a longitudinal seam portion of the tube (3) and fusing at least an internal outer surface (34) of the first lateral edge (19) and an external outer surface (37) of the second lateral edge (20) with one another for longitudinally sealing the seam portion of the tube (3). The step of fusing comprises at least the substeps of directly heating the external outer surface (37) of the second lateral edge (20) and heating by contact the internal outer surface (34) by establishing contact between the internal outer surface (34) and the directly heated external outer surface (37).

A method for fabricating wetsuit garment including wetsuits, boots and gloves for water sports uses, comprising preparation of at least a substantially elastic joining member made of hot melt adhesive, and joining at least two interconnected panels of rubber foam or sponge by the substantially elastic joining member to cover and seal the seam between the two interconnected panels for firmly bonding the two interconnected panels for making a strong, elastic and flexible wetsuit garment.

A three-dimensional decorative piece that is made of a thermoplastic synthetic resin and can retain bulkiness and shape by a core and a method of producing the same. The three-dimensional decorative piece includes an upper layer molded body made of an upper layer material with a metal vapor-deposited layer and having a three-dimensional shape with a convex portion formed on its front surface side through a high-frequency dielectric heating, a core formed by curing a flowable synthetic resin filled in the convex portion of the upper layer molded body, and a substrate bonded a back surface side of the core by fusion.

A laser-welded body includes at least three of resin members, which contain a thermoplastic resin including: a first resin member which is a laser-irradiated subject, has an absorbance a.sub.1 of 0.01 to 0.12; a second resin member which has an absorbance a.sub.2 of 0.1 to 0.9 and includes a butted part where ends of one or more resin members are brought into contact with each other; and a third resin member which has an absorbance a.sub.3 of 0.2 to 3.8, and the absorbances a.sub.2, a.sub.3 exhibited by the second resin member and the third resin member are attributed to the inclusion of nigrosine as a laser beam absorbent therein, and the resin members are overlapped in the above mentioned to form contacted parts at these interfaces, at least a part of the butted part and/or the contacted parts are laser-welded.

The present invention relates generally to coated abrasive articles, such as coated abrasive film belts having improved strength and durability, as well as methods of making and using said coated abrasive articles.

A method for monitoring a curing process of a cured-in-place pipe is disclosed. The method includes affixing a plurality of sensors to a resin layer of a liner, and determining a curing profile corresponding to at least the resin layer, the curing profile including a threshold curing value. The method further includes sensing, using the plurality of sensors, real-time data indicative of at least one curing parameter. Additionally, the method includes comparing the real-time data from each sensor to the threshold curing value, and outputting an alert upon the real-time data meeting or exceeding the threshold curing value.
