    摘要: Strands of material may be intertwined using weaving techniques, knitting techniques, non-woven or entanglement techniques, or braiding techniques. Fabric that is formed from the strands of material may be used in forming a fabric-based item. The fabric based item may include electrical components. The strands may include conductive strands that form signal paths. The signal paths can carry electrical signals associated with operation of the electrical components. Each strand may have an elongated core and a coating. Strands may also include intermediate layers between the cores and coatings. The cores, intermediate layers, and coatings may be formed from polymer without conductive filler, polymer with conductive filler, and/or metal. A polymer core may be provided with recesses to help retain subsequently deposited layers such as a metal coating layer. The recesses may be grooves that extend along the longitudinal axis of the core.

    摘要: A method of attaching wire to an exposed surface of an adhesive layer includes guiding wire from a wire source through a payout head and through a foot of a write head. A first portion of the wire extends from the foot toward the adhesive layer. The write head is positioned such that a gap between the foot and the exposed surface of the adhesive layer is greater than a diameter of the wire. The write head is moved in a motion parallel to the adhesive layer, and the first portion of the wire adheres to the adhesive layer. Wire is pulled from the wire source by the payout head as the write head is moving in order to maintain slack in a second portion of the wire between the payout head and the write head as the wire is attached to the exposed surface of the adhesive layer.
