Aus Mehrleiterdraht gewickelte sattelförmige Ablenkspule und Wicklungsverfahren

摘要

Saddle-shaped, flared deflection coil for display tubes, having two arcuate connection portions at the ends and two interposed coil flanks located at both sides of a window. The coil is wound by making use of two wire bundles which are simultaneously fed (by means of two winding arms or flyers). At certain instants during the winding process, the flyers can be moved apart in such a way that a pin can be inserted between the wire bundles. The result is a coil having (triangular) apertures in the flank portions in which one wire bundle extends along one side of each aperture and the other wire bundle extends along another side.
