Abstract: A blade mount is attached or detached without bolts to save the time for the attaching and the detaching. Consequently, the operation efficiency of the rotary die cutter is enhanced, which is intended to achieve. Two fixing rings are freely fitted to a knife cylinder and the driving unit rotates the screw axis to move moving mounts. Thereby, yoke plates disposed on the moving mounts move the fixing rings to the end portion of a blade mount, and then an activated unit activates fixing units to fix the fixing rings to the outer circumference face of the knife cylinder, so that the blade mount is fixed. After the fixing rings are fixed, the yoke plates are separated from the fixing rings, so that abrasion of the yoke plates can be avoided.

The swing roll is wrapped around the single faced corrugated cardboard, and the number of flute tips of the single faced corrugated cardboard that are concurrently contacting with the gluing roll and applied with the glue is adjusted by moving only the swing roll in such a direction that crosses a sheet face of the single faced corrugated cardboard passing through the nip.

Abstract: Reconditioning is performed such that the curvature of the arcuate surface of the crest on the upper corrugating roll is increased as compared before conditioning. Further, reconditioning is performed such that the curvature of the arcuate surface of the crest on the lower corrugating roll is increased as compared before conditioning. In this step, polishing is performed so as to maintain the maximum diameter of the crest on the upper corrugating roll as much as possible. Thereby, since the length of the inclined surface of the corrugating roll connecting between a crest and a trough of the upper and lower corrugating rolls and is reduced, the rate of the increase in the consumption of corrugated mediums of fluted corrugated mediums for double-faced corrugated cardboard sheets shaped by the upper and lower corrugating rolls and after reconditioning can be reduced.

Abstract: A squaring device provided to a counter ejector part that stops flat cardboard boxes fed from an upstream, using a front stop, in a downstream part of a box-manufacturing machine, receives and stacks the flat cardboard boxes in a stacking part in a hopper part, and ejects the stack as a batch. It includes a squaring plate that, while the stacking part retains in a stack position during a retention interval, squares the cardboard boxes stacked on the stacking part, in conjunction with the front stop, the retention interval being set in accordance with a feed speed of the cardboard boxes and a count setting for a stack of the cardboard boxes. A reciprocation driving unit drives the squaring plate to reciprocate toward and away from the front stop, and is configured to vary a speed ratio of a squaring speed for reciprocating the squaring plate, to the feed speed.
