ABSTRACT:
A domer assembly which cooperates with the punch of a drawing and ironing machine to reform an end wall of a container includes a support that has a flat supporting surface defined in the bottom of a recess and a carrier element having a cooperating surface engaging the flat bottom surface. A domer element is supported on the carrier element and both are movable as a unit radially of the path of movement of the punch and are normally centered with respect to the axis of the punch through biasing springs which will accommodate radial movement. The assembly also includes means for supplying air between the surfaces to act as a fluid bearing and reduce friction.
