Abstract: It is an object of the present invention to provide a sheet-fed printing press that prevents occurrence of troubles, such as damages of a surface treatment member such as a film for the surface treatment of, for example, a sheet of paper, by a simple structure. A gripping surface of a claw block provided in a cylinder of a treatment section is formed into an inclined surface that comes closer to the rotational axis as it advances downstream in a sheet conveying direction of the cylinder, so as not to have the gripper of the cylinder contacting the treatment means. A gripping surface of a claw block provided in a cylinder most adjacent to the treatment section, of plural cylinders, is formed into an inclined surface that, projects further through an outline of this cylinder as it advances downstream in the sheet conveying direction.

Abstract: A metal ring loading and unloading apparatus is capable of loading and unloading a metal ring quickly and highly accurately for increased efficiency. The metal ring loading and unloading apparatus has a moving unit 41 slidably movable along a rail 48 which extends from a loaded ring placement unit 8 to an unloaded ring placement unit 11. On the moving unit 41, there are mounted a loaded ring delivering unit 9 for holding and delivering a metal ring W on the loaded ring placement unit 8 and an unloaded ring delivering unit 10 for removing the metal ring W from support rollers 3, 4 and delivering the metal ring W to the unloaded ring placement unit 11. The loaded ring placement unit 8 has a pressing unit for radially pressing the metal ring W to deform the metal ring W into a substantially elliptical shape. The loaded ring delivering unit 9 has a loaded ring gripping unit 26 for gripping the metal ring W deformed by the pressing unit.

Abstract: An apparatus for correcting the circumferential length of a metal ring has a drive roller 2 and a driven roller 3 positionable closely to each other for training a metal ring W therearound, and a correcting roller 4 disposed between the drive roller 2 and the driven roller 3. The apparatus also has a first displacement applying unit for displacing the drive roller 2 and the driven roller 3 away from each other when the metal ring W is trained around the drive roller 2, the driven roller 3, and the correcting roller 4.

Abstract: A part housing or extracting apparatus is here disclosed which comprises a housing shelf which has a plurality of cylindrical bodies coaxially laminated in a vertical direction and equipped with at least one stage of a part housing unit the peripheral edge of which is partitioned into many columns so that the outer peripheral edge surface of the part housing unit may be opened, the respective cylindrical bodies being independently rotatable; at least one part housing or conveying means which has first part holding means disposed opposite to the outer peripheral surface of the housing shelf so that the part held by the first part holding means may be conveyed to a predetermined part housing unit and then housed therein; and at least one part extracting or conveying means which has second part holding means disposed opposite to the outer peripheral surface of the housing shelf so that the part housed in the predetermined part housing unit may be held and extracted by the second part housing means and then conve

Abstract: A display unit of a job aiding apparatus disposed in each of work stations displays a job detail display image for showing a job detail in each of the work stations and a job result display image for showing a job result of the job detail. The worker in each of the work stations can perform a job easily according to the job detail shown in the job detail display image, and can easily and accurately confirm the job result according to the job result in the job result display image.

Abstract: A display unit of a job aiding apparatus disposed in each of work stations displays a job aid image for showing a job detail in each of the work stations. The worker in each of the work stations performs the job according to the displayed job detail. The job aiding apparatus decides whether a job result falls within a predetermined range or not, and changes the job aid image to a next job aid image only when the job result falls within the predetermined range. The worker can thus perform the job accurately and efficiently.

Abstract: A turbine blade fitting apparatus for fitting multiple turbine blades radially to a disc having multiple disc grooves formed in its periphery. A blade preassembly is made by preassembling multiple turbine blades into a ring by connecting together their tips. The fitting apparatus has a second pedestal for temporarily placing the blade preassembly so that the upper face of the blade preassembly is higher than the upper face of a disc supported horizontally on a first pedestal. The second pedestal is lowerably supported by compression springs. Base parts of the blades are completely fitted into the disc grooves by the blade preassembly being pushed downward by a pushing mechanism while being vibrated.

Abstract: A tail edge side part 50b of a plate 50 disposed on a cylinder surface of a plate cylinder 1 is pushed in a direction of an arrow 100 with a blade 39 rotated in a direction of an arrow 91. At that time, a tail edge side lower plate 6 maintains an initial position. And the tail edge side part 50b is clamped by closing a tail edge side upper plate 7 with a condition that the tail edge side part 50b is in contact with the tail edge side lower plate 6 by the rotation of the blade 39.

Abstract: A ball quantitative supply system is comprised of an upper plate, a lower plate and a rotary block rotatably retained between the upper and lower plates. The upper plate is provided with a ball receiving aperture for receiving balls fed from a ball feeder, and a ball confirming aperture for confirming a predetermined number of balls, the apertures being provided to extend through different portions of the plate when seen in top plan. The lower plate is provided with a ball discharge aperture extending therethrough. The rotary block is provided with a ball receptacle extending therethrough for receiving a predetermined number of balls. The positions of provision of the ball receiving aperture, ball confirming aperture and ball discharge aperture are displaced from each other at an equal interval of 120.degree. as viewed in top plan.

Abstract: A method is provided for feeding a liquid material to a tree by using a liquid feeding apparatus which has a container body. A selected branch or root of the tree has bifurcated offshoots which are cut in a manner such that the bifurcated offshoots partially remain with the branch or root, and the liquid feeding apparatus is attached to the branch or root in a manner such that the remaining bifurcated offshoots are inserted into the container body. In this condition, the liquid material is supplied into the container body from a liquid storage tank while expelling air from the container body.
