A method comprising providing a polymeric substrate having a melting point of from about 130° C. to about 190° C., and locating a material layer onto the substrate, wherein the material layer comprises one or more polymeric materials that liquefy upon exposure to temperatures of at least about 100° C., to blend with a softened portion of the polymeric substrate. Upon exposure of one or more of the substrate and the material layer to a stimulus, the temperature is increased in a predetermined temperature zone of one or more of the substrate and material layer to cause blending of the one or more polymeric materials of the material layer with the softened portion of the polymeric substrate.

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).

In order to thermally cure a thermosetting adhesive quickly and with less energy, the bonded article (10) according to the present invention comprises an adherend member (1) having a thermal conductivity of 1 w/m.Math.K or more, an adherend member (2) made of a material which can adhere to the adherend member (1), and an adhesion portion that is formed of a cured product of a thermosetting adhesive (3) and that is in contact with both the adherend member (1) and the adherend member (2), wherein the adherend member (1) has a heat transfer-inhibiting structure (4) which inhibits the transfer of heat from a portion thereof in contact with the adhesive (3) to a peripheral portion thereof.

One exemplary aspect relates to a process and apparatus for selectively changing adhesion strength between a flexible substrate and a carrier at specific locations to facilitate shipping and subsequent removal of the flexible substrate from the carrier. The process includes providing a flexible substrate comprising a plurality of integrated circuits thereon providing a carrier for the flexible substrate and adhering the flexible substrate to the carrier by creating an interface between the flexible substrate and the carrier. The process further includes changing the adhesion force between the flexible substrate and the carrier at selected locations by non-uniform treatment of the interface between the flexible substrate and the carrier with an electromagnetic radiation source (e.g. a laser, flashlamp, high powered LED, an infrared radiation source or the like) so as to decrease or increase the adhesion force between a portion of the flexible substrate and the carrier at the selected location.

A laminate film manufacturing method is capable of preventing thickness unevenness of a cured layer and preventing wrinkling of the entire laminate film. A laminate film is manufactured by applying a coating solution including an active radiation curable resin to a surface of a first film that is continuously transported in an application part to form a coated film in a lamination part, laminating a second film that is continuously transported on the coated film to sandwich the coated film between the first film and the second film, and in a state in which the coated film is sandwiched between the first film and the second film, winding the first film around a backup roller and irradiating the coated film with infrared rays from an ultraviolet irradiation device while continuously transporting the first film to cure the coated film in a curing part so as to form a cured layer.

Method for manufacturing a reinforced part, including the steps of: producing a support structure and then covering the support structure, at least partially, with at least one composite material including reinforcement fibres, with local adhesion of the support structure and/or the composite material, during positioning thereof, to ensure its retention on the support structure, the support structure being an integral part of the reinforcing part.

A method of making a window assembly having an electrically heated portion includes providing a glass pane having a major surface. An electrically conductive material is disposed over at least a portion of the major surface of the glass pane. One or more wire assemblies are attached to the electrically conductive material. A light curable potting material is disposed over the one or more wire assemblies. The potting material covers a portion of each of the one or more wire assemblies and adheres to a portion of the major surface of the glass pane. The light curable potting material flows over the one or more electrical wire assemblies and the major surface of the glass pane such that in 1 minute or less the light curable potting material has an outer surface that is in a parallel relationship with the major surface of the glass pane. Also, the light curable potting material is dimensionally stable in 5 minutes or less.

A coating method comprises a workpiece acquiring step of acquiring a workpiece in which a metal member and a resin member the surface of which is activated by electron beam irradiation are connected to each other, and a coating step of applying a coating material to the metal member and the resin member of the workpiece.

An electric heating pad with electrosurgical grounding comprising a heated underbody support, heated mattress or heated mattress overlay. In an illustrative embodiment the heating pad with electrosurgical grounding may include a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges and a flexible sheet-like grounding electrode including an upper edge, a lower edge, and at least two side edges. A shell covering the heating element and grounding electrode and comprising at least two sheets (e.g., may be one sheet of material folded over to form two sheets) of flexible material, and a weld coupling the two sheets of flexible material together about the edges of the heating element and grounding electrode, wherein the weld is one of a RF weld, ultrasonic weld, or a heat bond, wherein the two sheets comprise PVC or urethane.

A method of manufacturing a de-icer assembly includes disposing a first welded-material layer and a second welded-material layer beneath a horn of a horn-based welding system, controlling the horn to move along a welded-portion pattern configured to weld the first welded-material layer to the second welded-material layer in the pattern of the welded-portion pattern such that inflatable portions are formed within the welded-portion pattern formed in the de-icer assembly between non-welded sections of the first welded-material layer and the second welded-material layer, and applying high-frequency energy to the first welded-material layer and a second welded-material layer using the horn such that the first welded-material layer and the second welded-material layer are welded together at areas in the shape of the welded-portion pattern to form a welded de-icer assembly.
