Abstract: It is sought to reduce the planar area on which a continuous paper web duplex inkjet printing unit is installed. To this end, a continuous paper web duplex inkjet printing unit for inkjet printing on both sides of a continuous paper web with an inkjet printing head in an inkjet printer is configured to comprise a plurality of inkjet printers 11a-11h disposed so that they lie vertically in steps and their inkjet printing heads face downwards, and a paper threading path 15 disposed below such an inkjet printer or printers in each steps for permitting the continuous paper web to be passed zigzag from an upper to a lower step successively.

Abstract: In a printed matter transport device wherein a printed matter is gripped by a gripping mechanism of a chain and made to travel along a guide rail, to improve the durability of the guide rail and chain, to prevent misalignment, falling out and damage when an external force acts on the printed matter, to improve durability of a connecting part of a chain link (base) and the gripping mechanism, to reduce manufacturing costs, and to enable the printed matter to be firmly gripped. A chain with grips comprising first rollers respectively arranged on two sides in the center of the longitudinal direction of the bases, a second roller on one side perpendicular to the common center line of the first rollers and a grip mechanism on the opposite side, a guide rail, a chain drive means and a cam member, a guide rail, a chain drive means and a cam member are provided.

Abstract: A signature-delivery-pitch regulating apparatus includes a grip mechanism adapted to grip a signature received in a rotating delivery fan, push the signature out of the delivery fan, and then release the signature on the transport conveyer operating at a speed slower than the moving speed of the grip mechanism. The grip mechanism includes at least one endless chain in meshing engagement with at least a first sprocket and a second sprocket. The first sprocket rotates at a position within a rotation locus of bottoms of signature receiving spaces of the delivery fan and in the vicinity of a region where the delivery fan comes close to the transport conveyer. The second sprocket has an outer circumference located outside the rotation region of the delivery fan. The endless chain can travel along the transport direction of the transport conveyer from a position inside the rotation region of the delivery fan to a position outside the rotation region of the delivery fan.

Abstract: A printing unit drive apparatus for a rotary press which includes a single or plural printing units and a single or plural folding units. The drive apparatus includes a motor capable of driving a driven portion of each unit, a connection mechanism for drivingly connecting the motor with the driven portion, and a brake mechanism and a reduction gear mechanism disposed in the connection mechanism. All or some of the motors are selectively combined and operated in a synchronized manner. When supply of electricity to the motors is stopped, the motors stop simultaneously without continuing their independent inertial rotation.

Abstract: A rotary press has a paper web supply apparatus, a printing apparatus, and a post-printing processing apparatus. The rotary press further includes at least one heating roller provided in a path along which a paper web carrying printed images runs from the printing apparatus to the post-printing processing apparatus, as well as at least one cooling roller provided downstream from the heating roller. The heating roller and the cooling roller are disposed such that the running paper web contacts each of the rollers over at least one-fourth of the circumference thereof. The heating roller is rotated at a circumferential speed different from a running speed of the paper web. The heating roller is a cylindrical body equipped with a built-in coil to which alternating current is supplied. The heating roller has cavities which are formed in a mutually communicating manner in the wall thereof and are filled with a thermal medium, and the outer surface of the heating roller is roughened.

Abstract: An offset perfecting press is disclosed which has a pair of blanket cylinders on opposite sides of a web traveling along a predefined path. Bearing different images to be printed, two plate cylinders are disposed in circumferentially spaced apart positions on each blanket cylinder. Each plate cylinder is independently movable between an image transfer position, where the plate cylinder is held to the blanket cylinder in order to print an image thereon for subsequent transfer to the web, and an image nontransfer position where the plate cylinder is spaced from the blanket cylinder. Only one plate cylinder is held in the image transfer position on each side of the web. For a change from one image to another, the plate cylinders that have been printing the opposite sides of the web are retracted to the image nontransfer positions, and the other plate cylinders, rotating in phase with the blanket cylinders, are moved to the image transfer positions. There is no need for stopping the web or the blanket cylinders.
