Abstract
An opening device for opening bagged refuse to liberate the contents of the bag, in which garbage bags are transported along a conveyor, and a plurality of endless chains having tines attached thereto are operated above the conveyor. As bags pass under the endless chains, tines extending downwardly from the chains pierce the garbage bags. Adjacent chains are operated at different speeds, and the tines move at different speeds relative to the conveyor, tearing the bags, liberating the refuse.
