ABSTRACT:
A glass banding for a dynamoelectric machine characterized by incorporating an irradiation curable resin impregnated in pre-stressed layers of the banding. The banding is further characterized by having a substantially uniform thickness of cured resin between each layer thereof, in the range between 0.5 and 2 mils, despite a variation in the pre-stressing tensions applied to the respective layers of the banding. A novel method is also encompassed by the invention for making an adhesively bonded, irradiation curable, resin treated glass banding that retains a pre-stress tension therein when the banding is subjected to a variety of mechanical vibrations and variations in temperatures applied to it.
