61 METHOD AND APPARATUS FOR EMBOSSING THE INSIDE SURFACE OF A CUP-SHAPED ARTICLE ABSTRACT OF THE DISCLOSURE A draw/emboss work station (18) of the invention includes emboss punch apparatus (86) moveable by a lever (340) and a hydraulic system under control of a press slide (34). Pressure sleeve apparatus (92) is slideable with respect to the emboss punch apparatus (86) and is responsive to force applied to it by the press slide (34). An emboss punch head (96) is moved downwardly into a cup-shaped article (14) to bring the article into a draw/emboss die (146) having an interior reduced diameter part (148). The emboss punch head (96) then remains stationary and spaced from the reduced diameter part a- predetermined distance to define an annular opening. The pressure sleeve apparatus (92) including a pressure sleeve (130) is then forced downwardly into engagement with a shoulder (64) on the cup (14), and forces the cup (14) through the annular opening to thereby simultaneously draw the sidewalls of the cup (14) and transfer the design of the emboss punch head (96) to the inside surface of the cup (14).
