ABSTRACT OF THE DISCLOSURE A method and apparatus for opening, emptying and disposing of 100 lb. paper, cloth or plastic bags of asbestos or other powdered or granular products by cutting longitudinally and transversely through one large bag face and perforating one or more remaining edges to produce a "U" or "H" shaped hinged flap through which the contents are emptied. Appro- priately located and sequentially actuated cutters, heated to from about 800°F. to about 1000°F., utilize heat and dropable to quickly and cleanly cut each bag on a hinged and dropable table while bag is held by arrangement of spikes which form a gripping head. Gripping head moves to discharge the empty bag from the apparatus. Air spikes on gripping head ensure complete emptying of bag contents, which flow down a discharge chute below the hinged table.
