Abstract
Apparatus for screen printing on cylindrical surfaces in which the driving force is created by rotation of the object to be imprinted. The force is transmitted by a belt mechanism and by direct friction between the object being printed and the stencil frame. The stencil frame is mounted for linear movement with minimum yawing and with freedom for vertical movement as required. The printer has particular advantage when the object being printed has a large moment of inertia or is circumferentially unbalanced.
Claims6
In a screen printing apparatus for printing on an object having a substantially circular cross section defining a curved surface, the improvement comprising
- a stencil assembly having a defined image printing area including;
- a printing screen and
- a frame supporting said screen,
- means supporting said stencil assembly for rectilinear movement,
- rotatable means for supporting the object to be imprinted, and
- means responsive to an external rotational force applied to said object arranged to move said screen linearly at a velocity equal to the circumferential velocity of the surface to be imprinted comprising
- at least one elongating belt connected to said stencil assembly and in engagement with the surface of the object to be imprinted.
