ABSTRACT:
Method and apparatus for making an easy open substantially rectangular bag of compressed flexible articles in which the flexible articles are arranged in a stack and held in compression in a direction substantially parallel to their thickness. The preferred method includes the steps of: (a) partially erecting a flexible bag including a substantially continuous line of weakness; (b) forming a stack of flexible articles; (c) compressing the stack of flexible articles between a pair of opposed knife belt assemblies; (d) inserting the knife belt assemblies into the open bottom end of the partially erected flexible bag; (e) simultaneously driving the opposed knife belts associated with the knife belt assemblies in a direction which advances the stack of compressed articles into contact with the innermost surface of the top panel of the partially erected flexible bag; (f) completely retracting the knife belt assemblies from the open end of the partially erected flexible bag; (g) folding the open bottom end of the partially erected, filled flexible bag to form a closed bottom panel; and (h) securing the bottom panel of the easy open bag in a closed position.
