To cutting delivery section 520, disconnecting device 530 and downstream delivery section 540.In process below, control unit repeats usually control
System and cutting control.
(usually control)
As shown in Fig. 2, control unit operates upstream delivery section 510 with setting speed in usual control, make to cut off with defeated
It send portion 520, downstream delivery section 540 to operate with the roughly equal speed of setting speed, conveys dry paper 101 (S1).Herein, it is
Tension is not generated to dry paper 101, preferably cutting delivery section 520, downstream delivery section 540 is adjusted to slower than setting speed
Speed, such as setting speed 95%~99.9% degree speed.
Next, it is determined that whether the front-end edge of the drying paper 101 of conveying reaches breaking distance (S2).Breaking distance is to cut off
It is the distance of basic point to 531,531 with the blade of delivery section 520, such as is comparable to the distance of the length of longitudinal direction A4.
(cutting control)
At the time of the conveying distance of dry paper 101 reaches breaking distance, control unit carries out cutting control.That is, making to cut off
Stopped with delivery section 520, downstream delivery section 540, respectively by second conveying roller pair 521a, 521b, third conveying roller pair 541,541

Also, disconnecting device 530 is operated, cuts dry paper 101 (S4) to 531,531 with blade.
First conveying roller pair 511,511 of upstream delivery section 510 is in usual control and cutting control both sides always with setting
Speed conveys dry paper 101 to cutting delivery section 520.Therefore, dry paper 101 is in the first conveying roller pair 511,511 and the
Between two conveying roller pairs 521a, 521b in Lr, upwards and until setting height Hr is bent into annular on transport path, it is detained
In bending part accommodating space portion 522.
The bending part for being trapped in the drying paper 101 in bending part accommodating space portion 522 jacks up pressing down section 523, pressing down section
523 swing upwards around support shaft 523a.
After disconnecting device 530 cuts dry paper 101, under the slice substance (cutting object) of the drying paper 101 after cutting passes through
Swim delivery section 540 with the velocity of discharge faster than setting speed (copy paper speed) at high speed sent downstream plummer (save sketch map
Show) (S5).
Judge whether the drying paper 101 is ground paper (S6).In addition, judging the conveying direction rear end of slice substance whether from blade
Set a distance Lset is opened up to conveying direction downstream separation to 531,531 edge of a knife.
When for thin paper, judge whether delivered such as 18mm (S7), when being ground paper, judges whether delivered such as 12mm
(S8)。
The judgement is according to following reason.After cutting dry paper 101, when by the second conveying roller of cutting delivery section 520
When discharging to 521a, 521b from clamp position, the drying paper 101 for being stranded in bending part accommodating space portion 522 is rapidly conveyed
To conveying direction downstream, to eliminate bending part.
At this point, the rear end of the slice substance of leading drying paper 101, is conveying 531,531 edge of a knife to third from blade
Roller is in 541,541 maximum distance Lmax, when opening up set a distance Lset to conveying direction downstream separation, subsequent ribbon
Front end will not collide the rear end of leading slice substance, can be avoided the generation of paper jam.
Also, control unit is during being transported to set distance Lset for slice substance rear end, be here above-mentioned 12mm or
Second conveying roller pair 521a, 521b of cutting delivery section 520 is maintained clamp position by 18mm, constrains the band-like of dry paper 101
Object.
Herein, the change control of the setting speed of upstream delivery section 510 (copy paper speed) is illustrated.By head box 23
The supply amount for being supplied to the paper pulp suspension of copy paper silk screen 22 maintains a timing, by the setting speed for increasing and decreasing copy paper silk screen 22
(copy paper speed) adjusts the thickness of l Water Paper 100.By the way that the supply amount of paper pulp suspension to be maintained centainly, can either ensure wet
The quality of paper 100 stablizes the adjustment for being able to carry out thickness again.
For example, when the supply amount of paper pulp suspension to be maintained centainly, and increase the setting speed (copy paper of copy paper silk screen 22
Speed) when, the thickness of l Water Paper 100 and dry paper 101 can be reduced and thinning.In addition, due to the increase of setting speed, cutting control
The bending part of the drying paper 101 generated when processed becomes larger.Therefore, control unit is transported to the above-mentioned 18mm phase in slice substance rear end
Between, the second conveying roller pair 521a, 521b of cutting delivery section 520 is maintained into clamp position, constrains the band-like of dry paper 101
Object.
Copy paper silk screen 22, dryer roll 410, the first conveying roller pair 511,511 do not need centainly to convey with identical speed wet
Paper 100 can also convey l Water Paper 100 at different rates respectively.Thereby, it is possible to prevent the broken of the l Water Paper 100 in copy paper process
Damage and relaxation, and suitably convey.
In addition, when the supply amount of paper pulp suspension to be maintained centainly, and reduce the setting speed (copy paper of copy paper silk screen 22
Speed) when, it will increase the thickness of l Water Paper 100 and dry paper 101 and thicken.In addition, due to the reduction of setting speed, cutting control
The bending part of the drying paper 101 generated when processed becomes smaller.Therefore, control unit is transported to the above-mentioned 12mm phase in slice substance rear end
Between, the second conveying roller pair 521a, 521b of cutting delivery section 520 is maintained into clamp position, constrains the band-like of dry paper 101
Object.
The cutting in cutting control is adjusted with defeated according to the increase and decrease of the setting speed (copy paper speed) of upstream delivery section 510
Send the dwell time in portion 520.

Portion can accelerate to start again at the delay releasing speed provided after conveying to the second conveying roller pair 521a, 521b.
At this point, not releasing the clamp position of the second conveying roller pair 521a, 521b, it will be able to avoid collision, eliminate bending section
Point.
5. the setting speed of upstream delivery section 510 is fast, compared with when the setting speed of upstream delivery section 510 is slow, control
Portion can reduce start again at conveying after to the second conveying roller pair 521a, 521b provide delay release speed.At this point, can keep away
Exempt to collide.In addition, bending part can be eliminated by releasing clamp position after starting again at conveying.
When not releasing clamp position, as needed, shorten dwell time when cutting, alternatively, by cutting delivery section
After 520 start again at conveying band object, delay releasing speed can be increased to the time of maximum speed by shortening, eliminated curved
Bent portions.
In the following, the rear end of leading slice substance opens up calmly 531,531 edge of a knife along conveying direction downstream separation from blade
When distance Lset, usual control is reverted to from cutting control.
That is, the clamp position (S9) of the second conveying roller pair 521a, 521b of release cutting delivery section 520.The release is logical
It crosses and is moved upward the conveying roller 521a of the non-drive side of top to carry out relative to the conveying roller 521b of the driving side of lower section.
By discharging the clamp position, the drying paper 101 in bending part accommodating space portion 522 is stranded in promptly to conveying
Square downstream transport eliminates bending part.Bending part hour, the ribbon of dry paper 101 in the elastic force short time by disappearing
Except bending part, restore the posture stretched, is stretched along transport path.
When bending part is excessive, the power for restoring to stretch posture dies down, and is not being pressed from both sides by the second conveying roller pair 521a, 521b
That holds becomes difficult without elimination bending part under restrained condition.
But the drying that pressing down section 523 is detained when cutting off control in bending part accommodating space portion 522 with annular
Paper 101 is lifted and is swung upwards.When discharging the state of the dry paper 101 of the second conveying roller pair 521a, 521b clamping, pressing down section
523 since its self weight is to bending part applied force downwards.
The power that 523 pairs of the pressing down section dry paper 101 apply helps to eliminate bending part, even if the bending of dry paper 101
Part becomes larger and the ribbon of bending part can also rapidly stretched on transport path.In addition, passing through the second conveying of release
Roller corrects wandering off for dry paper 101 to the clamp position of 521a, 521b.
Next, it is determined that whether have passed through the release time of setting after the state of the second conveying roller pair 521a, 521b of release
(S10)。

Delay release speed be increased and decreased adjustment.Therefore, the relaxation of dry paper 101 can rapidly be eliminated.
When the conveying speed of upstream delivery section 510 is slow, can also by slowing down the conveying speed of cutting delivery section 520,
The tension for adjusting ribbon, prevents the breakage of ribbon.
In the present embodiment, discharge the second conveying roller pair 521a, 521b clamp position be cutting control after again
It is secondary to start the progress of conveying initial stage.But as other steps, before discharging clamp position, can also be conveyed in maintenance second
In the state that roller is to the clamp position of 521a, 521b, conveying is started again at delivery section 520 by cutting off.Then, in transmission process
The middle clamp position released to the drying paper 101 of ribbon.
In addition, in the present embodiment, the clamp position of the second conveying roller pair 521a, 521b is released, it can also be complete
It does not discharge and is operated.
Also, it, can also be using the second conveying roller pair 521a, 521b not as other compositions of cutting delivery section 520
Close to isolated composition, using the composition for the mechanism for not having release clamp position.
At this point, repeating the rotation driving and rotation stopping of the second conveying roller pair 521a, 521b.Also, according to upstream
The conveying speed of delivery section 510, adjustment start again at the opportunity of the rotation driving of the second conveying roller pair 521a, 521b, that is, by cutting
After disconnected device 530 cuts off dry paper 101, cutting delivery section 520 starts again at the opportunity for conveying dry paper 101.Or according to
The conveying speed of upstream delivery section 510 adjusts the conveying speed of cutting delivery section 520.
It is not by discharging the clamp position of the second conveying roller pair 521a, 521b for the pine of dry paper 101 in this composition
Relax disposable elimination.Therefore, the ribbon that subsequent dry paper 101 will not occur collides the situation of leading slice substance.
Therefore, control unit follow the setting speed (copy paper speed) of upstream delivery section 510 increase and decrease and to cutting control in
Cutting be increased and decreased adjustment with the dwell time of delivery section 520.Also, follow the setting speed (copy paper of upstream delivery section 510
Speed) increase and decrease and to the delay of cutting delivery section 520 release speed be increased and decreased adjustment.
For example, the setting speed (copy paper speed) of upstream delivery section 510 is faster, more shorten stopping for cutting delivery section 520
The only time, so that the operating that starts again at for cutting off the cutting delivery section 520 after control be made to shift to an earlier date.Further, it is possible to inhibit due to
The increase of the slack for the drying paper 101 that the increase of setting speed (copy paper speed) generates.In addition, releasing speed by making to be detained
Near the degree for not causing collision, the relaxation of dry paper 101 can be rapidly eliminated.
