DEFINITION

Classification: 53/370.2

Including provision for pleat of cover overhang:

(1) Note. This subclass is intended to include package making apparatus wherein a pleat is merely disclosed as a part of the completed package, i.e., a showing of a pleat on the completed package in the drawings is sufficient to cause a package making apparatus to be included in this and the indented subclasses.
