ABSTRACT:
A printing system for the reproduction of large scale images by spray painting on a wide flexible medium such as vinyl or paper. A movable cradle is provided with a series of spaced endless belts that provide lateral support for the roll of medium to be painted or imprinted. The endless belts are in turn rotatably supported by a frame of sufficient strength to prevent significant bending of the structure. The belts are mounted on low-friction rollers that permit the medium roll to rotate as material is drawn from the roll into the painting system. The direction of material withdrawal is substantially vertical so that the roll remains in its controlled position as the size of the roll becomes smaller and to facilitate printing on either surface of the medium. The cradle is mounted on casters so that it can be readily moved into the frame of the painting system and locked in position. Because there is no removable axial support for the roll of medium, less space is required for the necessary manipulation of the medium.
