Abstract: An imaging apparatus includes one or a plurality of optical filters, an image sensor, an imaging signal processing part, a detecting part, and a control part. The one or the plurality of optical filters are selectively arranged in a path of an optical system for obtaining imaging light. The image sensor is provided for converting the imaging light obtained through the optical system into an imaging signal. The imaging signal processing part is provided for subjecting the imaging signal from the image sensor to a color-temperature correction processing. The detecting part is provided for detecting a type of the one or the plurality of optical filters arranged in the optical system. The control part is provided for adjusting a color temperature that is set at the imaging signal processing part to a color temperature defined for each filer detected by the detecting part.

Abstract: A pump for a printing press includes a plunger within a cylinder to be rotatable and reciprocatable and having a cutaway portion at its distal end, and a constant-speed motor for rotating and reciprocating the plunger. The plunger and the output shaft of the motor are radially offset relative to each other and inclined with respect to each other. The output shaft of the motor is coupled to the plunger via a transmission mechanism which includes an arm and a connection member. The arm is connected to, for example, the plunger, and the connection member is connected to, for example, the output shaft of the motor. The arm and the connection member are connected with each other at an eccentric position in such a manner that the arm and the connection member can displace relative to each other in the radial direction and can change the intersecting angle therebetween.

Abstract: Problems exist such as the presence of a narrow gap when the vicinity of a spliced joint of paper webs is passed between an outer surface of a roller and an outer surface of a folding cylinder. Paper blockages due to increased thickness are therefore likely to arise, making it easy for the paper web to become torn. This in turn damages the paper, and machine stoppages are also increased.

Abstract: A pump for a printing press includes a plunger accommodated within a main bore of a cylinder to be rotatable and reciprocatable and having a cutaway portion at its distal end, and a constant-speed motor for rotating and reciprocating the plunger. The plunger and the output shaft of the motor are radially offset relative to each other and inclined with respect to each other. The output shaft of the motor is coupled to the plunger via a transmission mechanism which includes an arm and a connection member. The arm is connected to, for example, the plunger, and the connection member is connected to, for example, the output shaft of the motor. The arm and the connection member are connected with each other at an eccentric position in such a manner that the arm and the connection member can displace relative to each other in the radial direction and can change the intersecting angle therebetween.

Abstract: The present invention is directed to an outside diameter adjuster for a folding cylinder. The folding cylinder rotates about an axis and has a basic body having a columnar outer circumferential face, where an outer circumferential member forms one portion of the outer circumferential face of the basic body and is movable in a radial direction of the basic body by the angular displacement of an eccentric portion. The eccentric portion is angularly displaced by gears to which it is connected. These gears are connected to other gears, some of which are helical gears, that are configured to rotate and/or axially move in a manner such that the angular displacement of the eccentric portion can be totally controlled by the movement of the gears while the folding cylinder rotates.

Abstract: In a pin action timing adjustment device of a folding device wherein a change-over between straight run and collect run is performed in one operation for a folding blade action and a pin action, to make it very easy to adjust a timing with which pins fall relative to the projection of folding blades, to make a mechanism very simple, to largely reduce manufacturing costs, to effectively eliminate the occurrence of faults so that maintenance is easy, and to provide an adjusting mechanism which permits ample adjustment tolerance. A control means is connected to a pin action stop cam which causes the pin action stop cam to undergo an angular displacement around its center line, and a stop means which can be connected to the pin action stop cam which has undergone an angular displacement due to the control means and stops the pin action stop cam with a phase displaced by the control means.

Abstract: A printing plates lifting apparatus having storing function in a rotary press having upper and lower printing units arranged in tiers and upper and lower work floors corresponding to the printing units. The printing plates lifting apparatus comprises upper and lower rotating bodies, opposed endless flexible bodies which are engaged with vertically opposed upper and lower rotating bodies, driving means for rotating the rotating bodies to run the endless flexible bodies, and printing plate hanging members arranged along and between the endless flexible bodies.

Abstract: A paper web threading apparatus for use in a paper web processing machine which aims at threading a paper web along a paper web threading path by moving a paper web threading member to which the paper web is secured along a guide member provided along the path, and which comprises detectors for detecting the paper web threading member which is moved along the guide member and outputting a detection signal; and an abnormality indication signal outputting device for outputting an abnormality indication signal when the detection signal is not outputted within a predetermined period of time during the movement of the paper web threading member.

Abstract: This invention provides a method of and an apparatus for sticking a paper web to a paper web threading member superposed on the paper web through the intermediary of an adhesive material.

Abstract: This invention has for its object to provide an apparatus for connecting a paper web with a paper web threading member wherein during the stand-by period of a retaining device the adhesive surface of an adhesive material in the retaining device is covered up by a movable cover so that paper dust or the like may be prevented from depositing thereon. The apparatus comprises a paper web retaining member connected to the upstream end of the paper web threading member and adapted to be located at a predetermined position along a paper web threading path where it is allowed to stand by; a retaining device for retaining a paper web, which has been advanced to the predetermined position along the path, onto the paper web retaining member through the intermediary of an adhesive material; and a movable cover provided in juxtaposition with the retaining device and adapted to be moved so as to selectively cover up or expose at least the adhesive surface of the adhesive material.
