Patent ID: 7261033

Claim:
Printing machine, comprising: a support stand ( 2 ), a plate ( 4 ) rotational with respect to the stand ( 2 ) about an axis of rotation (A-A), means ( 8 , 30 ) for driving the plate in rotation, at least two mandrels ( 6 ) for holding two articles to be printed in succession, the said mandrels being carried by the plate ( 4 ), means ( 94 ) for driving the mandrels in rotation about axes of rotation (B-B) parallel to the axis of rotation (A-A) of the plate ( 4 ), a plurality of workstations ( 18 , 18 A, 18 B) distributed around the rotational plate ( 4 ), and displacement means ( 22 , 24 , 36 , 64 , 82 , 98 ) for the displacement of each mandrel in a plane parallel to the plane of the plate ( 4 ), in order to modify the spacing between the axis of rotation (B-B) of the mandrel and the axis of rotation (A-A) of the plate, characterized in that the said displacement means comprises a control unit ( 98 ) and at least one actuator ( 82 ) for the displacement of the mandrels, the control unit being designed to synchronize the displacement of each mandrel ( 6 ) with the rotation of the plate ( 2 ), and the means ( 94 ) for driving the mandrels in rotation are carried by the stand ( 2 ) and the means ( 94 ) for driving the mandrels in rotation comprises releasable means ( 22 , 38 , 46 , 64 ) for rotational coupling to each mandrel ( 6 ).
