Abstract
A plastic sleeve is applied to a pole of varying cross-sectional area. A series of poles are advanced along their lengths through the opening of an extruder die, plastic is extruded onto the pole to form a cylindrical sleeve, and the rate of advancement of the pole through the die is adjusted in accordance with the increasing or decreasing diameter of the pole, so as to assure an even application of the plastic about the pole. The ends of the plastic are gathered while the plastic is still hot, forming a closure of the plastic about the ends of the pole.
