Abstract
A draw/emboss work station (600) of the invention includes emboss punch (594) moveable by a hydraulic system under control of a press slide (34). An emboss punch head (632) is moved downwardly into a cup-shaped article (626) to bring the article into a draw/emboss die (604). The emboss punch head (632) does not rotate while the draw die (604) does. The draw die (604) is allowed to rotate by thrust bearings (610 and 612). As the emboss punch head (632) pushes into the cup-shaped article (626) the downward rotational force is taken by the thrust bearing (612). As the emboss punch head (632) is withdrawn from the cup-shaped article (626) the upward rotational force is taken by the thrust bearing (610).
