Abstract: A method for manufacturing a shaft (1) in which linking members (3) are provided to ends of a cylindrical member (2) including: polishing end surfaces of a metal sheet; a bending step for bending the metal sheet into a cylindrical or arcuate shape; butting together the polished end surfaces of the metal sheet, the end surfaces facing each other in a state in which the metal sheet has been bent into the cylindrical shape, or disposing a plurality of the metal sheets that are bent into an arcuate shape so as to form a cylindrical shape and butting together the polished end surfaces of the metal sheets, and then heating the butted portions so that the butted portions are diffusion-joined, thereby forming the cylindrical member (2); cooling the post-diffusion-joining-step cylindrical member (2); and joining the linking members (3) to the ends of the cylindrical member (2).

Abstract: Provided is a method for manufacturing a ribbon piece that allows suppressing a damage of a rotary die cutter. A method for manufacturing a ribbon piece of the present disclosure includes punching out a ribbon piece from a ribbon material using a rotary die cutter. The rotary die cutter includes a die roll and an anvil roll. The die roll includes a die roll body, and a cutting blade is formed to protrude on an outer peripheral surface of the die roll body. The anvil roll includes an anvil roll body, a groove is provided on an outer peripheral surface of the anvil roll body, and the cutting blade is engageable with the groove with a space.

Abstract: In a sheet wrapping body producing apparatus, an oxygen absorbing strip sheet supplied from an oxygen absorbing sheet supplying shaft is cut out by a first rotary die cut unit to make an oxygen absorbing sheet tip. The tip is transported in such a manner to prevent the misalignment by a delivery drum unit and a first transportation belt unit. During the transportation, a breathing layer strip sheet is supplied on a transporting surface of the first transportation belt unit, on which the oxygen absorbing sheet tip is placed. Also, a strip cover film is placed on the oxygen absorbing sheet tip. Then, a rotary seal unit seals the breathing layer strip sheet and strip cover film, and the sealed portion is cut by a second rotary die cut unit. Accordingly, a sheet wrapping body can be produced at high speeds.

Abstract: In a stacking and forwarding apparatus, an array of work is continuously transported or rails by belts and a preceeding one of works is located and stopped in a receiving space defined by stoppers. The preceeding one of works is lifted by three guide rails which are located at left and right sides and front side of the work. Thus, a next work is received in the receiving space under the preceeding work and also lifted by the rollers. The pair of stacked works is pushed outside of the apparatus.

Abstract: An apparatus of this invention includes first and second supply rolls of wrapping film sheets. The film sheet is fed from first supply roll to a wrapping machine. The distal end of the film sheet of the second supply roll is partially fixed by an adhesive tape. In this state, the film sheet cannot be fed from the second supply roll. The second supply roll can be rotated in the forward or reverse direction. The apparatus also includes a knife for cutting the adhesive tape of the second supply roll. When the remaining length of the film sheet fed from the first supply roll becomes short, the knife is brought into contact with the outer surface of the second supply roll. By utilizing the rotation of the roll, the knife is inserted under the distal end of the film sheet of the second supply roll. Thereafter, the knife is moved along the outer surface of the second supply roll in the axial direction thereof, thereby cutting the adhesive tape of the second supply roll.

Abstract: A control method of operation of a collective packing machine, which packing machine is composed of a main packing machine and an auxiliary packing machine. The main packing machine is in continuous operation while the auxiliary packing machine is in stop waiting operation wherein the auxiliary packing machine is operated in matching and synchronization with the main packing machine. When the auxiliary packing machine is at the stop waiting state, the revolution speed of a main shaft of the main packing machine and the revolution speed of an input shaft of a clutch of the auxiliary packing machine are controlled by comparing and matching therebetween. When an output shaft of the clutch is stopped and operation of the auxiliary packing machine is started, operation starting time of the auxiliary packing machine is made earlier than the normal operation starting time by time t.sub.s. The time t.sub.

Abstract: An apparatus for piling rod-shaped articles in a container, in which a hopper member having at least one levelling means such as a swing pin is employed in combination with a push means. The rod-shaped articles temporarily collected in the hopper member are pushed out into the container by the push means at least every one layer thereof thereby to make an orderly pile of the rod-shaped articles in the container.
