Abstract
Abstract Sheets of garneted polyester are separated into a plurality of small pieces and each of the small pieces is generally formed into a rounded body suitable for blow injecting into an insulation receiving pocket formed in goods such as coats, sleeping bags and the like, in accordance with the method and apparatus provided. The rounded bodies formed may generally be used similarly to and as a substitute for natural down insulation. The rounded bodies formed are approximately uniform in size and weight, and the size of each of the bodies is sufficiently small to avoid clogging of the blow injecting tubes and paths of the apparatus utilized in filling the goods with insulation. Each of the rounded bodies include a plurality of randomly oriented polyester fibers therein, and each of the rounded bodies provides a substantial resiliency to permanent deformation after the application of force to them.
