Vorrichtung zum UEber-Kopf-Abwickeln eines Drahtes von einer Vorratsspule

摘要

A device for longitudinally unwinding a metal or partially metal wire from a supply reel which is comprised of a central core portion and a pair of flanges at each end thereof, the wire being wound to form a wire parcel about the core between the flanges. The surface of at least one of the flanges which is adjacent the wire parcel has a portion thereof of gradually decreasing radial dimension in a direction opposite to the longitudinal direction of unwinding thereby forming a conical surface extending over approximately 60 to 70 percent of said surface of the flange. This conical surface facilitates the unwinding of the wire without breaking.
