The purpose of the invention is to stop a variety of sheets while absorbing the impact and to prevent problems generated by sheets colliding with a front stopper while in a state of being inclined to the front or rear. A front stopping device that receives sheets being sent along a horizontal transport route on a hopper unit and stops the movement in the direction of travel comprises: a plate-shaped buffering member (101) which is directly contacted by the front part of a sheet (10); and supporting members (103, 104) that supports the upper end and lower end of the buffering member (101). The buffering member (101) is formed of a flexible material to absorb the kinetic energy of the sheet (10) by elastically deforming into a concave shape when receiving the front part of the sheet (10), and the buffering member (101) is supported by being inclined up or down by the supporting members (103, 104) so that the restoring force that pushes back the front part of the sheet (10) due to the restoration of the elastic deformation contains a vertical component.

A corrugated roll is reprocessed such that the curvature of the arc-shaped curved surface of a ridge (12) of an upper corrugated roll (10) is made greater than that before processing. Also, the corrugated roll is reprocessed such that the curvature of the arc-shaped curved surface of a ridge (22) of a lower corrugated roll (20) is made greater than that before the processing. In this case, grinding is performed so as to maintain the maximum diameter of the ridge (12) of the upper corrugated roll (10) as much as possible. This enables the shortening of the length of the inclined surface of a corrugated roll connecting the ridges and valleys of the upper and lower corrugated rolls (10, 20), thus making it possible to reduce the rate of increase in the consumption of a core (d) of a corrugated core (e) of a double-sided corrugated board sheet (j) which is formed by the upper and lower corrugated rolls (10, 20) after the reprocessing.

Disclosed is an arrangement wherein installation bolts are not required for installing and removing a blade mounting block, with the result that it is made possible to reduce the time to install and remove the blade mounting block, and wherein thereby improvement is made in the operational efficiency of a rotary die cutter. Two fixing rings (16a, 16b) are inserted over a tubular knife cylinder (10) with some play allowed in-between. By means of a drive device (28), a threaded shaft (18) is rotated, resulting in movable mounts (20a, 20b) being moved. By means of yoke plates (24) which are provided to the movable mounts, the fixing rings are moved to both ends of a blade mounting block (14). In this state, fixing devices (40) are operated by means of operation devices (60). Thereby the fixing rings are fixed to a knife cylinder outer peripheral surface (12), resulting in the blade mounting block (14) being fixed. After the fixing rings are fixed, the yoke plates (24) are separated from the fixing rings. Therefore, it is possible to prevent wear of the yoke plates (24).

When a joint margin of a cardboard sheet is formed by a slotter of a box forming machine, an uncut portion must be formed between a slotter scrap and a flap scrap corresponding to an arbitrary shape of the joint margin to prevent scattering of flap scraps, and to prevent adhesion failure of joint margins and mixture of a flap scrap into a cardboard sheet. An upper slotter knife (10) is formed to be divided into a slotter knife main body (12) and a division body (14), and the relative position between the division body (14) and a slide body (26) in which a flap cutter knife (30) is embedded is determined and fixed so that a gap (L) between a notch (18) formed on a part of a cutting blade (15) of the division body (14) and a blade edge of the flap cutter knife (30) is minimized. Thereby, even if the sizes or shapes of the cardboard sheet (1) or the joint margin (5) are different, due to the presence of the notch (18), an uncut portion (9) can be inevitably formed between the slotter scrap (7) and the flap scrap (8).

Disclosed is a paper discharge device for a printer and an operating method therefor. The device comprises a first transport conveyor (31); a second transport conveyor (34) downstream therefrom; a pressing member (36) that reduces the speed of quires (1b) discharged from the first transport conveyor (31) and presses the quires against a belt (35) of the second transport conveyor (34); and a control device (40), which, in a specific operation when a defective sheet of paper is mixed among the quires (1b), sets the velocity ratio RV (V2/V1) of the transport velocity (V2) of the second transport conveyor (34) to the transport velocity (V1) of the first transport conveyor (31) to a first velocity ratio (RV1) that is greater than a reference velocity ratio RV0, and which, during normal operation, when a defective sheet of paper is not mixed among the quires (1b), sets the velocity ratio RV to the reference velocity ratio RV0 so as to transport the quires (1b) in a staggered manner. Thus, it is possible to suppress the occurrence of paper jams near the pressing member in situations in which defective sheets of paper may easily appear; in addition, in the event that a paper jam occurs, it can be easily resolved.

When printing plates are exchanged in a printer (1), the plate mounting portions (37a, 37b, 37c and 37d) of individual printing drums (32a, 32b, 32c and 32d) turn to the positions where they confront plate exchanging devices (35a, 35b, 35c and 35d). When the exchanges of the printing plates are ended, moreover, the individual printing drums (32a, 32b, 32c and 32d) turn so that the individual plate mounting portions (37a, 37b, 37c and 37d) may have predetermined phase differences. The actions of the printing drums (32a, 32b, 32c and 32d) before exchanging the printing plates are performed at the time of washing blanket drums (33a, 33b, 33c and 33d), and the actions of the printing drums (32a, 32b, 32c and 32d) after the printing plates are exchanged are performed simultaneously with an inking operation.
