Claims

1. IN A JACKET FOR A CAPACITOR, A HOLLOW CYLINDRICAL MEMBER CONSTRUCTED OF A PLURALITY OF SUPERPOSED LAYERS OF PLASTIC MATERIAL, EACH LAYER COMPRISING A LAMINATE OF POLYETHYLENE AND ETHYLENE TEREPHTHALATE, EACH LAYER BEING HELICALLY ARRANGED, WITH A POLYETHYLENE LAMINA IN ONE LAYER BEING FUSED TO THE POLYETHYLENE LAMINA IN AN ADJACENT LAYER, ONE END OF SAID MEMBER BEING CONSTRICTED WITHOUT DELAMINATION, THE OTHER END OF SAID MEMBER BEING ENLARGED.

4. A CONDENSER JACKETYING METHOD, COMPRISING:

(A) PROVIDING A CYLINDER CONSTRUCTED OF HELICALLY WOUND LAYERS ARRANGED IN OVERLAPPING RELATION WITH EACH LAYER BEING A LAMINATE OF ORIENTED ETHYLENE TEREPHTHALATE AND POLYETHYLENE AND WITH A POLYETHYLENE FACE OF ONE LAYER BEING IN CONFRONTING, UNITED RELATION WITH A POLYETHYLENE FACE OF THE OTHER LAYER, (B) MOUNTING SAID CYLINDER ON A TUBULAR DIE WITH ONE CYLINDER END PROJECTING BEYONG THE DIE, (C) HEATING THE PROJECTED END PORTION TO A TEMPERATURE ABOVE THE REORIENTATION TEMPERATURE FOR SAID ETHYLENE TEREPHTHALATE TO SHRINK SAID END PORTION INTO A RADIALLY INWARDLY-EXTENDING LIP, (D) REMOVING SAID CYLINDER FROM SAID DIE AND PRIOR TO APPLYING SAID CYLINDER TO A CONDENSER, (E) PROVIDING THE OTHER END OF SAID CYLINDER WITH A RADIALLY ENLARGED PORTION, (F) INSERTING A CAPACITOR INTO THE ENLARGED END OF SAID CYLINDER, SAID CAPACITOR BEING SIZED TO PROVIDE A PORTION OF SAID CYLINDER PROJECTING BEYONG SAID CAPACITOR AT SAID CYLINDER OTHER END, AND (G) HEATING THE PROJECTED OTHER END TO A TEMPERATURE ABOVE THE REORIENTATION TEMPERATURE OF SAID ETHYLENE TEREPTHALATE TO SHRINK SAID OTHER END INTO A RADIALLY INWARDLY-EXTENDING LIP TO LOCK THE CYLINDER ON THE CONDENSER.
