ABSTRACT:
An apparatus is provided for manufacturing a cushioning package containing an article to be packaged. The apparatus includes a cushioning sheet forming unit to form a cushioning sheet by heat-sealing flexible elongated resin sheets which are continuously fed in a longitudinal direction and placed one on another in advance in a width direction of the sheet, the cushioning sheet including small sacs. Downstream from the cushioning sheet forming unit, an article storage space forming unit is provided for forming an article storage space by folding the cushioning sheet along a longitudinal centerline. A sheet adhering unit adheres the overlapped cushioning sheets. An article disposing unit inserts the article to be packaged into the article storage space, and an air filling unit fills the small sacs with air. Sequential performance of the above steps achieves efficient manufacturing of cushioning package.
