    Abstract: There is disclosed a novel apparatus and process for nesting a plurality of drum bodies or shells of deformable material wherein a cylindrically-shaped drum body is subjected to a force in a plane substantially parallel to the axis of the drum body to deform the drum body to the extent necessary to permit the positioning of a second drum body about the initially deformed drum body whereupon the deforming procedure is repeated for the nested first and second drum bodies, and is thereafter again repeated until a desired number of drum shells are contained in the resulting nested assemblage of drum bodies or shells.
