摘要：A machine comprising a base and an elongated cradle pivotally mounted on thebase is used to facilitate separation of nested tapered drums from a stack. With thecradle in an upright position, the machine is moved toward the stack to embrace the
stack in the cradle. A pair of clamps on the cradle embrace and grip successive drums at alower end of the stack, and then the cradle is moved to a lay-down position, carrying thestack with it. A first clamp of the pair, gripping a first drum, is moved away from a secondclamp of the pair and then releases the first drum so that it can be separated from thesecond drum. The first clamp is then moved toward the second clamp. The second clampreleases the second drum, and the laid-down stack is moved along the cradle to align thesecond drum with the first clamp and a third drum in the stack with the second clamp.The first and second clamps then grip the second and third drums, respectively, and thefirst clamp is again moved away from the second clamp. The first clamp then releases thesecond drum to permit the second drum to be separated from the stack.
