ABSTRACT:
The present invention is a flexographic printing apparatus for printing single images on a continuous web of material using a belt-type printer and for easily and rapidly creating flexible packaging by bringing the printing operation in-line with the bag converting or packaging material machines. In a preferred embodiment, the printing apparatus includes a frame having an impression cylinder and a nip roller rotatably mounted to the frame in close proximity to the impression cylinder such that the nip roller bears on the impression cylinder, a printer mounting attached to the frame and movable laterally relative to the impression cylinder, a belt-type printer mounted on the printer mounting and means for transferring rotation of the impression cylinder to the printer. The frame may be fixed to a post-printing processing machine or may be free-standing for easily moving the invented apparatus to various locations. Thus, the invented printing apparatus enables the belt-type printer to be used in-line with the post-printing processing machine. The impression cylinder is rotatably driven by a continuous web of non-rigid material being pulled through the printing apparatus by the in-line post-printing processing machine. The transfer means enables the printer to be operated solely by the rotation of the impression cylinder. Preferably, the printing mount is slidable on the frame laterally with respect to the impression cylinder for locating images at any desired position on the continuous web of non-rigid material.
