Abstract

An embossing apparatus (22) includes an embossing wheel (28) having a punch side (30) and a die side (32). The embossing wheel (28) has punch blocks (50) and die blocks (52) spaced around its periphery. A card (20) is carried to an embossing position by card transport (24) and aligned by a guide plate (36). The embossing is done by pushing the punch blocks (50) and die blocks (52) against the card (20) by a hammer (42, 42a) driven by a solenoid (38, 38a). Character return plates (46, 46a), located on the outer sides of the embossing wheel (28) engaging the inside of character blocks (35), spring the character blocks (35) and solenoid shaft (40, 40a) back to a home at rest position when the embossing stroke is completed. The solenoids (38, 38a) have bumpers (54, 54a) mounted thereon for controlling the motion of the shaft (40, 40 a).
