Abstract: A print carousel for color images having a plurality of radial arms carrying objects to be printed incrementally reaching a corresponding number of work stations by sequential incremental rotation of the carousel by a certain angle, a silk-screen printing ink-pot functionally installed in several of said work stations alternately to work stations of drying/polymerization of respective silk-screen printing ink or paste applied in the work station precedingly reached by the object to be printed, has at least one of said work station equipped with a supporting structure for a color digital plotter mounted on slides running on radially oriented guides, from an outermost limit position to an innermost limit position.

Abstract: An extrusion die having an extrusion slit defined by two lips one of which is flexible. A plurality of thrust members are disposed very close to one another and bear against the flexible lip. A drive motor is individual to each thrust member for rotating each thrust member to move the flexible lip toward or away from the other lip. A universal joint directly connects an output shaft of each motor to its respective thrust member. The output shafts are at oblique angles to their respective thrust members and some of the output shafts are disposed at substantial angles to others of the output shafts, whereby the motors are staggered.
