Abstract
Abstract This invention refers to a novel arrangement for mounting a vibratory assembly concentrically within a cylindrical housing for use in a vibratory seam welding apparatus. A pair of metal diaphragms support the vibratory assembly at antinodal regions of motion along the longitudinal axis. These diaphragms are constructed for supporting the assembly within the housing and for providing acoustic energy isolation between the vibratory assembly and the housing while being yieldable in the direction of the vibratory motion along the axis of the assembly.
