Abstract Apparatus for dispensing a packaging material and for packaging articles which includes a support for a roll of packaging material and a concave table for receiving articles to be packaged. The material is drawn over the table and by reason of the concavity, the articles are automatically centered on the material so that the material can be folded over the articles and sealed along the edges.

Claim 1
Independent Claim
116 words
Packaging apparatus for articles comprising a frame including means for supporting a roll of self-sealing packaging material in strip form, a table carried by said frame, said table being concave to receive an article or articles to be packaged, cutting means disposed along the outer edge of said table and means transversely bridging said concave table and spaced from said cutting means whereby articles to be packaged are placed on said packaging material overlying said table and centered by said concavity and said material upon being folded over upon itself and at least partially overlying said bridging member and sealed about the edges to complete the package is severed from said strip by said cutting means.
Claim 2
Dependent Claim
