A method for sealing the edges of composite fiber components includes applying a thermoplastic semifinished product to a cut edge of a composite fiber component and thermoplastically or integrally joining the thermoplastic semifinished product to the cut edge of the composite fiber component by ultrasonic welding.

In one aspect, a method for manufacturing a continuous sheet for use within a roller shade may generally include positioning a portion of a first sheet web adjacent to a mandrel, positioning a portion of a second sheet web adjacent to the mandrel and winding the first and second sheet webs around the mandrel such that a folded segment of the first sheet web is secured to a base segment of the second sheet web.

The present invention relates to a device for producing a reinforcing structure, which comprises a fiber-reinforced strip having a thermoplastic material, onto a molded body surface. The device is characterized in that emission direction vectors of at least two laser diodes of a laser diode array are aligned in a non-parallel manner to one another and are directed toward one another in the direction of a heating surface of the strip and/or the molded body surface.

The present disclosure relates more to processes for making a filter element that includes a filter membrane having a strip of thermoplastic polymer material laminated thereto, for example, as a strip along an edge of the filter membrane. For example, one such process includes providing a sheet of filter membrane having a first surface and an opposed second surface; providing a strip of thermoplastic polymer material having a first surface and an opposed second surface; contacting the first surface of the strip of thermoplastic polymer material with the first surface of the filter membrane; and softening the strip of thermoplastic polymer material at at least its first surface by irradiation with laser radiation; such that the softened polymer material of the first surface of the strip of thermoplastic polymer material bonds to the first surface of the filter membrane upon hardening.

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.

Disclosed are novel copper foils used as components of wireless charging systems. The copper foils can be laminated to produce flexible copper clad laminates, which can then be etched to form printed circuits (coils). The coils can be used as either, or both, of a receiver wireless charging circuit and/or a transmitter wireless charging circuit. Regulation of the chemical and physical properties of the copper foil produces higher efficiencies in the wireless charging system components.

An induction heating device having two superimposed conductors is provided, comprising a first conductor having a first electrically conducting pattern; a second conductor having a second electrically conducting pattern; wherein the first electrically conducting pattern and the second electrically conducting pattern are: i) connected to an alternating current in use; ii) superimposed thereby resulting in at least one section where the first electrically conducting pattern overlaps the second electrically conducting pattern; and iii) separated by at least a space arranged for accommodating material with an electrically conducting layer, wherein when the alternating current is supplied, the alternating current in the first electrically conducting pattern in a specific section has the same direction as the alternating current of the second electrically conducting pattern in said section.
