Abstract
The collector bag is provided that includes a fabric formed to define an internal volume, a plurality of sewn loops for disposal about an outer periphery of the collector frame, and a gather of fabric at each of the plurality of sewn loops for disposal about an inner circumference of the collector frame. The plurality of sewn loops are secured to the gather so that the internal volume of the collector bag, when disposed on the collector frame, is at least about 90 percent of a maximum volume of the collector frame.
