ABSTRACT:
A pulp mold comprises at least a cushion section for positioning and cushioning an article. In one embodiment of the invention, the cushion section is comprised of a plurality of pulp mold strips, and in other embodiments, the cushion section is formed by a number of successive pulp mold units, each unit defining a ridged surface on the pulp mold. A molding means for manufacturing the units comprises upper mold members and lower mold members, together defining the units, with each lower mold member being connected between two successive upper mold members. The upper mold members are used to form the ridged surfaces of the units for contact with an external packing material, such as a cardboard box or a carton, and the lower mold members, in addition to defining the units with the upper mold members, are used to form bottom surfaces each connecting two successive units. These bottom surfaces define an envelop plane completely fit with the contour of the article to be packaged. When the contour of the article changes, only the lower mold members are replaced and the upper mold members can be retained.
