An apparatus for vacuum thermoforming and printing plastic articles from a continuous web of plastic material in which a rotatable vacuum thermoforming drum has a plurality of vacuum thermoforming dies mounted on circumferentially surfaces. The drum further comprises a gear path and a cam path, each with a plurality of substantially flat and curved sections. A print structure in a frame includes a device for imparting ink to the articles after they are formed, and a linear bearing adapted to allow the printing cylinder to move in a constrained motion substantially normal to the central axis. The printing cylinder comprises a shaft with a pinion gear to engage the gear path and a cam roller to engage the cam path. As the drum rotates, the articles are formed, printed and separated in substantially a single operation.

1. An apparatus for vacuum thermoforming and printing plastic articles from a substantially continuous web of plastic material, said apparatus comprising: a. a vacuum thermoforming drum for receiving said substantially continuous web, said drum being rotatable about a central axis and having a plurality of die mounting surfaces arranged circumferentially thereon, at least one said die mounting surface comprising a vacuum thermoforming die defining said articles;b. said drum further comprising a gear path and a cam path, i. said gear path comprising a plurality of substantially flat geared sections aligned with said die mounting surfaces and a plurality of substantially curved geared sections between said substantially flat geared sections,ii. said cam path comprising a plurality of substantially flat cam path sections aligned with said die mounting surfaces and a plurality of substantially curved cam path sections between said substantially flat cam path sections;c. a vacuum source operably attached to said drum for drawing said substantially continuous web into contact with said vacuum thermoforming die;d. a drive for rotating said drum;e. at least one print structure arranged in a print structure frame and comprising a printing cylinder adjacent said drum for contacting and imparting ink to said articles after said articles are formed, i. said print structure frame comprising a linear bearing adapted to allow said printing cylinder to move in a constrained motion substantially normal to said central axis,ii. said printing cylinder further comprising a print cylinder shaft having a pinion gear adapted to engage said gear path and a cam roller adapted to engage said cam path;whereinrotation of said drum causes rotation of said gear path and said cam path;rotation of said gear path causes said pinion gear to rotate said print cylinder in synchronism with the rotation of said drum; andsaid cam roller and said cam path are adapted to maintain engagement of said pinion gear and said gear path as said drum rotates. 2. The apparatus of claim 1 wherein said drum further comprises a second gear path and a second cam path; said print cylinder shaft further comprises a second pinion gear adapted to engage said second gear path and a second cam roller arranged to engage said second cam path; andsaid pinion gear and said cam roller, and said second pinion gear and said second cam roller, are adapted to be selectively engagable;whereby engaging said pinion gear and said cam roller, and disengaging said second pinion gear and said second cam roller, allows for forming and printing said articles with dies of a first die height; and engaging said second pinion gear and said second cam roller, and disengaging said pinion gear and said cam roller, allows for forming and printing articles with dies of a second die height. 3. The apparatus of claim 1 comprising at least two said print structures, whereby each said print structure is capable of printing using a different color ink, thereby enabling said articles to be printed using multiple colors. 4. The apparatus of claim 3 wherein said print structures are arranged perpendicular to one another. 5. The apparatus of claim 1 further comprising a motor and an eccentric gear wherein said motor is affixed to said print structure frame and adapted to drive said eccentric gear; said eccentric gear is operably connected to said print cylinder such that rotation of said eccentric gear adjusts a distance between said print cylinder and said drum; whereby operation of said motor allows adjustment of said print cylinder to allow for different die heights and different printing pressures. 6. The apparatus of claim 1 further comprising a die cutter for cutting said articles from said substantially continuous web. 7. The apparatus of claim 1 wherein said substantially continuous web comprises a heated, extruded, thermoformable plastic material, and said vacuum forming drum is adapted to allow cooling of said articles after thermoforming. 8. The apparatus of claim 1 wherein said drum comprises a plurality of gear paths and cam paths; said print cylinder shaft further comprises a plurality of pinion gears, each said pinion gear adapted to engage one of said plurality of gear paths;said print cylinder shaft further comprises a plurality of cams, each said cam adapted to engage one of said plurality of cam paths; andsaid gear paths, cam paths, pinion gears, and cam roller are adapted to be selectively engagable;whereby engaging one said pinion gear and one said cam roller allows for forming and printing said articles with dies of a predetermined die height.
