(under subclass 170) Apparatus for folding, wrapping or otherwise forming two or more flat, superimposed blanks into a plural layered cover for the contents, at least the initial wrap being applied simultaneously to all the blanks.
(1) Note. A laminated cover material, having the various layers uniformly adhered to each other over their contacting surfaces prior to the fabrication of the material into a cover and handled by the packaging machine as though there were but a single layer, is classified as if the cover material were in fact composed of but a single layer.
