Abstract
A method of stuffing an aerated expanded flexible filler into a snug fitting cover, wherein air is evacuated from the filler while resting upon a support so as to shrink the filler and permit rapid application of the cover thereto. The apparatus includes a cantilevered chambered support with multiple openings in its filler supporting surface and selectively operable means for withdrawing air from the chamber and an air impervious sheet draped over the filler and the support.
Claims9
Apparatus for use in the application around an air pervious expanded flexible filler of a flexible cover envelope open at a margin thereof and of a size and shape when closed which closely conforms to the normal expanded size and shape of the filler, in combination,
- a horizontal filler supporting member,
- means mounting said supporting member in cantilevered relation to accommodate application of said opened flexible cover envelope around the free end of the supporting member and articles supported thereon,
- means defining a plurality of air flow passages open in substantially uniformly spaced relation in at least a selected portion of the upper surface of said supporting member,
- a flexible substantially air impervious sheet draped over said filler supporting member and a filler supported thereon and spanning all air flow passages not spanned by said filler, and
- means located adjacent to said supporting means and connected to said passages to generate a sub atmospheric pressure in said passages and the space between said sheet and said supporting member and thereby collapse said filler and accommodate encirclement of said filler, sheet and the portion of said supporting member which supports said filler by said cover envelope when open.
