Abstract: A method, apparatus, and system for winding a filament around a substrate includes mounting the substrate to a rotatable structure and rotating the substrate to wind the first filament around the substrate in a first winding orientation that winds the first filament around a first pair of edges of the substrate to wrap a first filament layer around the substrate. The method further includes changing winding orientations of the first filament from the first winding orientation to a second winding orientation by turning the first filament about a corner of the substrate and winding the first filament around the rotating substrate in the second winding orientation that winds the first filament around a second pair of edges of the substrate, wherein the second pair of edges is different from the first pair of edges, to wrap a second filament layer around the substrate.

Abstract: A transformer and method of making includes first half primary and secondary windings as metallic circuits that are etched on a metallic cladding of a first liquid crystal polymer (LCP) sheet. Secondary windings are positioned in spaced relation to the primary windings. A second LCP sheet is applied over the first LCP sheet. Second half primary and secondary windings are etched as metallic circuits on a metallic cladding of a second LCP sheet. Respective first and second half primary windings are interconnected to each other and the first and second half secondary windings are connected to each other by conductive vias.

Abstract: A coil winding apparatus 1 includes a transvers mechanism which displaces a wire supply part 8 and a spinds 5 to which a bobbin 4 is fitted relative to each other in an axial direction. This traverse mechanism includes a first traverse mechanism 11 and a second traverse mechanism 15 which have a different displacement range and displacement pitch. The first traverse mechanism 11 and second traversemechanism 15 are displaced independently of one another, so even when a wire of fine diameter is rapidly wound on a narrow width, the coil winding alignment does not break down, and the coil turns can be wound at high speed in an orderly arrangement.

Abstract: Device to form spirals in a coiling machine for trolled stock located downstream of a rolling train provided with drawing rollers, wherein the coiling machine includes a reel able to rotate around an axis of rotation, including a guide element suitable to guide the rolled stock in a segment between the drawing rollers and the coiling machine, first translating means being suitable to cooperate with the guide element to displace at least one end of the latter in a direction substantially parallel to the axis of rotation of the reel.

Abstract: An apparatus for winding a thread around a surface of an object while rotating the object. The apparatus includes a plurality of guide members. The guide members selectively guide a plurality of threads to the surface of the object. One guide member corresponds to one thread. The guide members move along the object. A moving device moves a selected one of the guide members.
