The present invention broadly is directed to enhancements to various bag splitting apparatuses. One such improvement for splitting open garbage bags containing stacked paper includes a row of pivotally-mounted blades mounted for rotation away from the filled bags and having a serrated lower edge with downwardly-projecting teeth that confront the bags being conveyed through said assembly, followed by a row of pivotally-mounted blades mounted for rotation away from the bags and having a serrated lower edge with teeth projecting into and confronting the bags being conveyed through the assembly. The corresponding method for splitting open bags containing stacked paper forms another aspect of the present invention.
