Abstract
A packaging separator adapted to be disposed in load bearing engagement between a pair of articles, such as windshields. The separator includes a sheet-like supporting element constructed of a generally nonresilient plastic foam and having enlarged opposed side surfaces for respectively contacting opposed surfaces associated with a pair of adjacent windshields. The supporting member has one or more shallow recesses formed inwardly from one of said side surfaces, and each recess contains therein a sheet-like gripping pad constructed of a resilient foam. The gripping pad, in a resiliently nondeformed condition, has a thickness which is significantly greater than the depth of the recess to define an outer gripping surface which extend generally parallel with but is normally spaced outwardly from the respectively adjacent side surface of the supporting element. The gripping pad is resiliently compressed by engagement with the windshield to the extent that the gripping pad projects beyond the respective side surface, thereby controlling the gripping pressure between the gripping pad and the adjacent windshield, with the primary force transfer occurring due to direct engagement between t…
