Patent ID: 8474376

Claim:
A device for printing by means of screen printing an object having at least a conical portion, the conical portion having a conical centre and a cone angle, the device comprising: a frame; a mobile screen relative to the frame, the screen having a mesh with a pattern to be printed on the conical portion of the object, the pattern having the shape of a conical evolute having a pattern centre and an angular extent range of the pattern; a squeegee which is carried by the frame, the squeegee being capable of pressing the mesh of the screen against the conical portion of the object in order to apply the pattern to the conical portion of the object, wherein the device comprises: a driving means for rotating the screen around an axis of rotation, said driving means for rotating the screen comprising a single motor, a first displacement means of the motor for rotating the screen during the printing of the object, said first displacement means extending in a first direction, a second displacement means of the motor for rotating the screen during the printing of the object, said second displacement means extending in a second direction perpendicular relative to the first direction, the first displacement means carrying the second displacement means, wherein, the squeegee is i) independent from the driving means for rotating the screen, and ii) independent from the first and second displacement means of the motor for rotating the screen, so that i) the screen and not the squeegee is moved by the motor and by the first and second displacement means, and ii) the squeegee is movable independently from the screen relative to the frame.
