The invention is a machine and method for opening a filled bag and emptying the contents of the bag. A bag filled with a solid material is guided into a space between a pair of rotating drums, in which there are several rows of rigid spikes fastened to each drum. The spikes extend through the drum walls and through openings in a belt that connects each drum to an idler roller. When the filled bag enters the space between the drums, it becomes impaled on the spikes, and is drawn into a cutter means. The cutter means slits the bag in half to empty the contents, and each empty bag half is carried on one of the rotating drums to a point where the spikes move away from the belt to release the empty bag half.
