Abstract: A down quilt in which a tubular closure section is provided on an opening in the quilt through which a feather feeder nozzle is inserted. A first fastener is provided at the opening and a second fastener is provided on the closure section so that feathers supplied into the interior of the quilt are prevented from escaping through the opening, whereby the quality of the down quilt can be maintained for a long time.

Abstract: A feather quilt comprising upper and lower cloth layers, a multiplicity of rectangular spaces arrayed in regular rows and files in the interspace between the upper and the lower layer, and down placed to fill up the rectangular spaces is manufactured by sewing ribbon-like partition pieces to the inner sides of the upper and lower layers along the individual boundaries of the rectangular spaces running in the longitudinal (or lateral) direction and T-shaped partition pieces to the aforementioned inner sides along the individual boundaries of the rectangular spaces running in the lateral (or longitudinal) direction, sewing together the corresponding ribbonlike partition pieces fastened to the upper and lower layers, similarly sewing the T-shaped partition pieces together with the exception of the openings formed of the projecting portions thereof, and sequentially filling with down the rectangular spaces formed between the upper and lower layers by the use of a down injection tube inserted through the openings
