Abstract: Traditional methods of making headlamp coils have left a portion of the coils with slightly irregular forms. These irregularities can result in defects in the ultimate beam pattern. Accommodating these defects in robust lamp and headlamp optical systems can reduce the performance that might otherwise be available. The preferred coil is therefore continuously coiled as a straight body, and carefully cut into segments. Subsequently, legs are welded to the coil segment ends. The coil is then left substantially undistorted by the manufacturing process that would otherwise normally leave a portion of the coils distorted. The method particularly enables a functional center leg coil.

Abstract: An in-situ curing filament winding process for making high quality flywheel rims at low cost, and the rims made by the process, and also an apparatus for performing the process, continuously cures resin during the filament winding process. A lower winding process temperature is used along with a lower cure temperature and inherently higher toughness epoxy resin system allows for the rim to be wound continuously, using a conservative radial deposition rate of approximately ¼-½ inch per hour. Multiple types of fibers can be used in a rim where they best serve the strength and stiffness requirements of the structure. The winding temperature can be kept at approximately 55° C.-80° C., providing low thermal residual stresses. Aliphatic amine or ether amine curing agents with epoxy resin generally work well to reduce the winding temperature and allow low viscosity, but other resin systems that provide similar characteristics can be used.

Abstract: A winding apparatus is capable of winding an element wire at a predetermined winding position on winding portions with good alignment of windings by defining the winding positions of the element wire on its winding progress side, regardless of variation of the predetermined winding positions. The element wire is guided to winding positions for the first winding layer on a winding frame, by moving a box member to a position apart from the turn immediately previously formed on the frame, by an amount equal to the diameter of the wire in the direction of winding progress along the axis of the winding frame. While this positioning is maintained, an element wire supplying reel is revolved around the winding frame, and thereby pays out the element wire. Therefore, the element wire is guided to the predetermined winding position defined by the box member and the previously formed turn, and the wire is wound at the winding position.
