The invention relates to a method for manufacture of a product or in completion of a product. A flexible mat (20) is manufactured from an incompletely cured thermo-setting plastic, wherein the mat comprises an article (10) of electrically conductive material. The incompletely cured mat (20) including the article (10) is then formed as a function of a forming tool or to lie against or for contact with a product, whereafter final curing of the mat (20) is executed by supplying electric power to the article (10) or by external heat application or ultraviolet light. The invention also relates to an arrangement and uses.

A method is described for opening a heat bonded sterile connection that includes a skin of material blocking flow between the connection site. The method includes applying external pressure to the connection site.

The present invention relates to a method for connecting two joining elements, these elements being connected by means of a thermally activatable adhesive with a flat heating element arranged therein, by suitable heating of the adhesive. The invention also relates to an assembly produced in this way from two joining elements and to an arrangement designed for carrying out a corresponding method.

A method for the sterile connection of pipes, consisting of: providing a first and a second pipe; a separating area of the first and second pipes is heated; both pipes are mechanically separated by exerting traction and/or shear force onto the pipes so that both pipes are respectively separated in the heated separating area; after the pipes are separated, a mechanical contact between the end of the first pipe section of the first pipe formed by the separation of the first pipe is established with the end of the first pipe section of the second pipe, formed by the separation of the second pipe, and mechanical contact is established such that the ends of the pipe sections still have, following heating when they come into mechanical contact with each other, a temperature such that they form a material fit connection without additional heating after separation.

A method for forming a connection between two tubular sections having a polymeric outer surface jacket, using electrofusion to fusion bond a casing of similar, non-crosslinked polymer to the outer surface of the tubular sections.

Methods and devices for bonding a plurality of substrates in a nip provided between an anvil and a bonding device may involve preheating a portion of a first substrate for a preheating duration to impart a preheated temperature, and then conveying the plurality of substrates to the nip to form a bond. The portion of the first substrate may reach the nip at a final temperature that is within 0 C. to 40 C. of the preheated temperature. A time-in-nip to create the bond may be less than 20 milliseconds. The preheating duration may be at least 200% longer than the time-in-nip. Laminate materials formed via such methods and devices may include unbonded areas in the nonwoven material that may have at least 5 fibers per square inch that are fused at fiber-to-fiber intersections caused by preheating the nonwoven material.

The invention provides a wind turbine blade comprising a first shell, having a first bonding region, and a second shell having a second bonding region, wherein the second bonding region of the second shell is bonded to the first bonding region of the first shell; and a temperature sensor positioned between the first bonding region and the second bonding region. Having a temperature sensor positioned within the turbine blade, in the region at which the two shells of the turbine blade are bonded together, allows for accurate determination and control of the temperature of the critical bonding regions during blade manufacture. The temperature sensor may be used during the service life of the wind turbine blade to detect delamination of the wind turbine blade.

A device for joining a first component to be welded to a second component to be welded, the joining device having at least one electrically conductive, resistive heating film which comprises a central connection portion and two lateral electrical connection portions. The joining device comprises at least one first electrical insulation member which is positioned in contact with the first face of the heating film, and at least one second electrical insulation member which is positioned in contact with the second face of the heating film, the two electrical insulation members being configured to allow the transfer of heat and to prevent the flow of electric current between the heating film and each component to be welded.
