A drawing and ironing assembly consists of a redraw assembly, at least one ironing assembly and a stripper assembly that cooperate with a punch to redraw a cup and then iron the sidewall thereof. The redraw assembly includes a support and a redraw ring which are also biased to a centered position and a floating air bearing is defined between the support and the frame surface to reduce friction while a nesting ring is located adjacent the redraw ring. Lubricating means are provided for creating a generally circumferential flow into the opening in the nesting ring. The stripper assembly includes a support which carries the stripper elements and the support is biased to a centered position with respect to a predetermined axis or path for the punch and fluid is supplied to relatively movable surfaces to assist in reducing friction.
