Abstract
A domer assembly for use with a punch reciprocable along a path on a frame of an ironing machine to reform an end wall of a container includes a center domer element surrounded by an annular element that projects beyond the surface of the center element with separate support means for the respective elements. The support means consists of a first support member carrying the center domer element with resilient compressible members interposed between the support member and the frame and a second support member supporting the annular element and also having a resilient member between the frame and the support. The respective resilient compressible members are identical in construction and are exposed so that they can readily be inspected, with independent separately pressurizable means for the respective compressible members.
