Abstract

A daisy type print wheel has its plastic hub and spokes laminated to a layer of springy metal to provide enhanced fatigue life characteristics. A springy sheet metal layer, such as phosphor bronze or beryllum copper, is precut or chemically milled to conform to the hub and spoke dimensions of the wheel. The metal layer can then be affixed (by cementing, ultrasonic bonding, etc.) to the back of the print wheel. The laminated design provides enhanced fatigue life resulting from the metal layer and provides se1f~damping resulting from the plastic layer.
