The distortion correction method of thin slice body, cutting-off method, distortion correcting device and shearing device

The application is the dividing an application of Chinese patent application of the application number submitted on October 8th, 2000 is 00129673.6, denomination of invention is the thin slice body distortion correction method, cutting-off method, distortion correcting device and shearing device.

The present invention relates to provide curling distortion correction method, cutting-off method, distortion correcting device and the shearing device that waits distortion and cut off the thin slice body of revising the rolled sheet body.

In general, have the various image recording mediums (thin slice body) such as photographic light-sensitive material, hotness paper or hot pressed paper of macromolecule support (polymer sheets body), constitute by on support, for example being coated with recording layer (emulsion layer of taking pictures).As support, for example use polyethylene terephthalate (PET), PEN (PEN), the laminated paper of tygon, cellulose triacetate film or mylar etc.

Above-mentioned image recording medium or paper wood etc. are made as coiled material usually, use as film with reeling condition.Therefore, for image recording medium, in time process under volume state is batched defective (below be called curling) producing on the support, residual curling on the image recording medium thin slice after the wafer processes process of cutting off etc.Therefore, the problem that has the carrying of image recording medium or accumulation property significantly to worsen.And then when handling with various processors such as developing machine or printing machines, the problem that carrying is bad or image forms takes place in this image recording medium thin slice, makes and can not carry out desirable processing.In the case, form the back at image and have the curling problem that might cause quality.

Therefore, in order to remove this curling, various suggestions have been proposed, for example, open in the clear 51-16358 communique (hereinafter referred to as conventional example 1) the spy, disclosed at the midrange of the glass transformation temperature scope that makes polymeric film or be related in the temperature range that the maximum glass transformation temperature (Tg) of heat absorption reduces by 30～5 ℃ through heating the method for film in 0.1～1500 hour.

In addition, open in the clear 62-31653 communique (hereinafter referred to as conventional example 2), disclosed the curling antidote that cools off after the photographic light-sensitive material heating that will be rolled into web-like the spy.Specifically, photographic light-sensitive material after the heating-up temperature of (50 ℃～100 ℃) below the fusing point heats 2～20 seconds, is cooled to than the low temperature more than 15 ℃ of this heating-up temperature.

But in above-mentioned conventional example 1, in fact therefore this polymeric film of heating under the temperature of 30 ℃～5 ℃ of the Tg reductions that makes polymeric film want to remove to curl, and just needs quite long heat time heating time.Consequently, can not remove expeditiously curls handles, and causes taking place the storage loss of film, and also has the problem of equipment enlarging.Worse is that long-time heating is damaged the danger of the picture characteristics deterioration of recording layer.

On the other hand, in above-mentioned conventional example 2, it is quite high that heating-up temperature has become.Under this high temperature, if reach 2～20 seconds heat treated, image recording layer just is affected, and has the significantly reduced problem of picture characteristics.And then, though relatively stipulate chilling temperature, often under than the higher temperature of the glass transformation temperature of support, cool off with respect to heating-up temperature.The result is often to produce in the carrying after the cooling processing and curl.

And, in above-mentioned conventional example 2, setting heating condition respectively based on the material of support, therefore in the kind of the recording layer of photographic light-sensitive material not simultaneously, can not mate suitably.Point out that just if the kind difference of recording layer, thermotolerance is also just different, produce inappropriate problem on hot photographic fog or the qualities such as tone change or hair check based on kind.And then, follow the variation of processing speed, heating condition also changes, and the excessive or not enough danger of the heat of generation is arranged.Therefore, often can not get desirable crimp removal effect or cause variety of problems such as quality is bad.

In addition, for example open in the clear 60-2559 communique (hereinafter referred to as conventional example 3) the spy, disclosed the curling apparatus for correcting of paper roll, this device comprises the heater means that the above-mentioned paper roll that made the rectification parts that the paper roll of reeling on the core at volume is bent along its take-up direction and reverse direction and will utilize this rectification parts bending heats.This heater means comprises the well heater by electric motor driven fan and the air heat that will send from said fans.Calculate based on information such as the diameter of paper roll or paperys and to batch intensity,, control the thermal value of the revolution or the above-mentioned well heater of above-mentioned motor corresponding to this curling intensity.

But in above-mentioned conventional example 3, based on the curling intensity of the above-mentioned paper roll that gradually changes with the residual amount of paper roll etc., temperature or the air quantity of correctly controlling hot blast with the height response are extremely difficult.Therefore, can not obtain the problem of the curling effect of desirable removal really for paper roll.And, owing to remove the kind difference of the rolled sheet body that curls,, the inappropriate danger that produces on the quality is arranged because of excessive heating.

And then, for example open in the flat 6-64808 communique (hereinafter referred to as conventional example 4) the spy, first quarter moon shape axle is freely rotated in use, the little shaft portion of radius contacts above-mentioned workpiece when sending to of workpiece (thin slice body) moved, remove curling of this workpiece, and the big shaft portion of radius contacts above-mentioned workpiece when stopping sending to, so that stop this workpiece is produced opposite curling.That is, follow the running of production line or stop,, stop workpiece is produced rightabout curling (contrary curling) by conversion crimp removal means.

, in removing curling device, based on the kind of workpiece, the acceleration-deceleration of the processing speed that changes and re-treatment speed continually or situation about stopping, in this device, existence can not be used the problem of above-mentioned conventional example 4.By the processing speed of variation workpiece, remove the effect of curling and also change, therefore can not finish the curling processing of desirable removal effectively.

In addition, for example from the macromolecule support (hereinafter referred to as the web-like support) that is rolled into web-like with the uncoiling of support coiled material, after being coated with recording layer (emulsion layer of taking pictures) on the above-mentioned support coiled material, extensively be rolled into the operation of web-like once more.On this web-like support, because the distortion that produces in time under the web-like state etc., so-called otch takes place and shows near spreaded all over a few the volume core distortion easily.This otch shows the coating process of the above-mentioned recording layer of influence, causes that the coating of above-mentioned recording layer is irregular, has the low problem of quality.Therefore, generally in process, that near a few parts the volume core are discarded, so just there is yield rate to reduce uneconomic problem.

In addition, disclose as opening the spy in the flat 8-142209 communique (hereinafter referred to as conventional example 5), the planarity of known road thermoplasticity film is improved one's methods, this method is continuously by heating the film coiled material with far infra-red heater and warm-up mill on one side, the roller heating process that planarization was transmitted and carried out on one side, and the volume film that has just finished this roller heating process on one side with the chill roll cooling, the roller chill roll process that one side is transmitted and is cured, simultaneously broad ways is distinguished the far infra-red heater of above-mentioned roller heating process, individually carries out temperature corresponding to the flatness of film and sets.

But in above-mentioned conventional example 5, when the material of film or thickness change, or the film speed that comprises acceleration-deceleration is when changing, or when production line taking place stopping, just being difficult to promptly change the heating condition of above-mentioned film.Therefore, on film, produce excessive heating, on film, had the danger that elongation takes place.

Especially when cutting off the hot display material of hot video picture photosensitive material etc., adopt upper knife edge and following blade to clamp the method for cutting off, but because the image formation layer (photosensitive layer or thermonasty layer) of hot display material is thick and crisp, thus the film that takes place to be caused by cut-out is easily peeled off, crackle so peel off at the bottom of the film base etc. improper.Thus, the problem that has the performance degradation that causes image formation layer.

As this countermeasure, up to now, adopt the report to the leadship after accomplishing a task methods such as adjustment, reduction cut-off velocity of relative position such as angle or snap-in force of the interval clamping angle of adjustment, upper knife edge and following blade of the trickle shape of the adjustment of one the point of a knife angle (mainly being to go up sword) in upper knife edge and the following blade or point of a knife.

, the adjustment of the shape of upper knife edge in the past and following blade or clamping angle etc. often exist can not solve that the film that is caused by cut-out is peeled off, crackle and then the shortcoming of problem such as peel off at the bottom of the film base.In addition, the adjustment of the shape of upper knife edge and following blade or clamping angle etc. is because be small adjustment, so also there is its shortcoming difficult in maintenance.

; as with stretch crystallization film, lamination material, metal material serving as the cutting-off method that cuts off object; have the spy to open flat 9-85680 communique, special justice-7-905 No. 12 communiques, spies open flat 5-111898 communique, in these communiques, disclosed when cutting off and heated.

Yet in the hot display material as cut-out object of the present invention, image formation layer (coated film) is layered on the basalis as multilayer film, in the coating film thickness thickening of above-mentioned image formation layer, also becomes fragile.Therefore, add in the cut-out of hot display material and to produce and to peel off by shape at the top layer film man-hour, perhaps come off, the improper of crackle perhaps taken place in image formation layer as bits.

Specifically, shown in Figure 64, hot display material 1 comprises basalis 2 and comprises the image formation layer 3 of photographic layer or hotness layer.Need point out to exist following problem at this: when this hot display material of crosscut, at upper knife edge side section, on the top layer of image formation layer 3, take place must shape surface layer peeling 4 or top layer crackle 5, and at blade side section down, generation crackle 6 above-mentioned image formation layer 3 in.

On the other hand, shown in Figure 65, add man-hour in that hot display material 1 is carried out rip cutting, the distension that exists in upper knife edge side section generation image formation layer 3 plays 7, at blade side section down the problem of crackle 8 takes place in above-mentioned image formation layer 3 simultaneously.

In the 3rd sequencer 350, be provided with by the 4th phase inverter 368, be used for drive controlling and cut off the 4th servomotor 370 of means 348, simultaneously in above-mentioned the 4th servomotor 370, be provided for detecting the 4th pulse producer 372 of the position information of above-mentioned cut-out means 348.

The action of the removal crimping device 340 of Gou Chenging will be illustrated by reference flow diagram shown in Figure 32 in conjunction with the removal coiling method of the present invention's the 11st embodiment like this.

At first, based on waiting to implement thick etc. the thin slice body information of the papery of removing the paper roll 14a that handles of curling or paper, set heating-up temperature and the heat time heating time of thin slice paper web 12a.Then, slave unit sequencer (not shown) is carried setting signal heat time heating time (step S1c) to the 1st sequencer 344, corresponding to this heat time heating time, sets the side-play amount (step S2c) of waving roller 266.

Specifically, as shown in figure 33, the roller 266 that waves during production line stops to dispose corresponding to the retreating position A that leaves warm-up mill 30.Then, an input equipment starts ready signal (step S3c), just carries to the 2nd phase inverter 356 from the 1st sequencer 344 and waves the roller position command.Therefore, under the effect of the 2nd servomotor 74, wave roller 266 and make above-mentioned thin slice paper web 12a coiling move (step S4c) to desired location C from the winding start position B between warm-up mill 60 and the thin slice paper web 12a.

As mentioned above, the skew action one of waving roller 266 finishes (step S5c is), just enters step S6c, and never illustrated equipment sequencer is to the 2nd sequencer 346 input drive signals.The 2nd sequencer 346 drives the 3rd servomotor 362 by the 3rd phase inverter 360, makes suction drum 18 begin rotation thus.Under the turning effort of suction drum 18, transfer rate based on the thin slice paper web 12a that sends from paper roll 14a, it is linear velocity, as shown in figure 34, never the highest setting signal of production line that illustrated equipment sequencer is sent, after accelerating to linear velocity Vmax, carry out constant speed with this linear velocity Vmax and transmit.

As shown in figure 35, change the coiling amount of waving roller 266 of speed VR2 control by the 1st change speed VR1 and the 2nd corresponding to linear velocity.Promptly, after production line starts beginning, wave the coiling amount of roller 266 and control (step S7c) by the 1st change speed VR1, when reaching the coiling amount position of linear velocity correspondence, in the 11st embodiment, when reaching linear velocity VR1 (step S8c is), just enter step S9c, follow the above-mentioned coiling amount of waving roller 266 of control with the 2nd change speed VR2.

On the other hand, as shown in figure 36, the linear velocity V that is produced by suction drum 18 as shown in figure 37, until reaching linear velocity VS, follows the coiling amount that roller 266 is waved in control according to the 3rd change speed VR3 when Vmax slows down.So one becomes this linear velocity VS following (step S10C is), just, wave roller 266 positions and determined at retreating position A (step S11C) according to the 4th change speed VR4 control coiling amount.

Like this, in the 11st embodiment, when the linear velocity V when production line begins quickens, and the production line that slows down of linear velocity is when just having stopped, the length of the periphery by thin slice paper web 12a Contact Heating roller 60 changes, and the time (heat time heating time) of the above-mentioned warm-up mill 60 of above-mentioned thin slice paper web 14 contacts is controlled at necessarily.

Specifically, as shown in figure 35, Vmax is set in Vmax=70m/min with linear velocity, will speed up time set at 8 seconds, will be set in heat time heating time 0.7 second, V1 is set in V1=9m/min with graded speed, initial stage coiling amount L0 is set in L0=30mm, and the time set of will reeling at the initial stage is at 0.4 second, carries out the experiment that compares with existing method, obtains result shown in Figure 38.Thus, in the 11st embodiment, near production line during acceleration that especially rate of change of on-line velocity is big begins, by the coiling amount L0 (30mm) that predesignates is set, the heat time heating time of the thin slice paper web 12a the heating starting position near can be guaranteed effectively, the curling effect of removal of above-mentioned thin slice paper web 12a can be obtained reliably.

On the other hand, as shown in figure 37, Vmax is set in Vmax=70m/min with linear velocity, ts is set in ts=8 second with deceleration time, to be set in heat time heating time 0.7 second, and coiling second cosmic velocity VS will be set in VS=12.25m/min, carry out and experiment that existing method compares.Its result in the 11st embodiment, especially near the on-line velocity stop position, is not provided with necessary above heat time heating time as shown in figure 39, can prevent the quality reduction of thin slice paper web 12a etc. reliably, has and finishes the effect that good removal is curled and handled.

Therefore, in the 11st embodiment,, or carry out the acceleration and deceleration of linear velocity or the occasion that stops continually repeatedly, also have to obtain the curl advantage of effect of desirable removal reliably even in the kind change process speed of corresponding thin slice paper web 12a.Especially, even in the occasion that incalculably can set linear velocity V continuously, or the occasion of in handling the way, carrying out the variation of linear velocity continually, also can finish efficiently and remove curling the processing.

The curling method of removal of relevant the 12nd embodiment of the present invention then, is described below.The 12nd embodiment uses the thin slice body system of processing 342 of similarly packing into and removing crimping device 340 with the 11st embodiment.

The 12nd embodiment is set the coiling amount L1 or the side-play amount of waving roller 40 as shown in figure 40, follows production line to start beginning, according to change speed VR5 control coiling amount.On the other hand, when on-line velocity is slowed down, as shown in figure 41,, finish the disengaging of reeling with linear velocity VS1 according to change speed VR6 control coiling amount.

In addition, in Figure 40, Vmax is set in Vmax=70m/min with linear velocity, will speed up time set at 8 seconds, will be set in heat time heating time 0.7 second, initial stage coiling amount L1 is set in L1=40mm, and the time set of will reeling at the initial stage compares experiment 0.5 second and existing method.Its result as shown in figure 42, in the past, after heating has just begun, reduce heat time heating time significantly, in contrast, and in the 12nd embodiment, keep heat time heating time effectively, from heat just begin after, 12a just can guarantee the uniform heating time to the thin slice paper web, is finished the effect of remove to curl handling efficiently.

On the other hand, in Figure 41, Vmax is set in Vmax=70m/min with linear velocity, to be set in deceleration time 8 seconds, to be set in heat time heating time 0.7 second, and coiling second cosmic velocity VS1 is set in VS1=6.42m/min and compares experiment heat time heating time in the past.Its result as shown in figure 43, in the 12nd embodiment, even especially near the on-line velocity stop position, also can keep desirable heat time heating time, begin during stop from production line, 12a can keep the uniform heating time to the thin slice paper web, efficiently and accurately finishes it and remove to curl handles etc. and the 11st above-mentioned embodiment obtains same effect.

The removal coiling method of the present invention's the 13rd embodiment below is described in addition.

In the 13rd embodiment, when on-line velocity is quickened, carry out the control of coiling amount as shown in figure 44.Specifically, on-line velocity V from 0 accelerate to linear velocity V11 during, after the coiling amount is controlled to coiling amount L12 according to the 1st change speed VR7, from corresponding to the linear velocity V11 of coiling amount L2 to reach linear velocity Vmax during, control above-mentioned coiling amount according to the 2nd change speed VR8.Moreover, when on-line velocity is slowed down, carry out the control identical with the 13rd embodiment.

In addition, Vmax is set in Vmax=70m/min with linear velocity, will speed up time set at 8 seconds, to be set in heat time heating time 0.7 second, V11 is set in V11=5m/min with graded speed, and graded coiling amount L2 is set in L2=95mm, detect and the experiment of the variation of heat time heating time in the past.Its result as shown in figure 45, in the 13rd embodiment, can maintain the heat time heating time that production line has just started near the thin slice paper web 14 of beginning effectively, finish efficiently and remove the processing etc. of curling, obtain and the above-mentioned the 11st effect identical with the 12nd embodiment.

And then, in the 12nd and the 13rd embodiment, especially linear velocity can be set in discrete several values, does not carry out the occasion of linear velocity change in transmitting the way, quality and the curling effect aspect of removal from thin slice paper web 12a have the advantage that can be fit to use.

The removal coiling method of the present invention's the 14th embodiment then, below is described.

As shown in figure 46, when on-line velocity is quickened, before production line starts beginning, set the coiling amount L3 that waves roller 266, production line is started working under the turning effort of suction drum 18.So linear velocity one reaches the speed V12 corresponding to deviation post, wave roller 266 and just be driven, follow the position that roller 266 is waved in linear velocity control.Thus, can avoid the deficiency of the heat time heating time after production line has just started, can finish efficiently and remove the processing etc. of curling, obtain and the above-mentioned identical effect of the 11st～the 13rd embodiment.

On the other hand, when on-line velocity is slowed down, carry out the control of coiling amount as shown in figure 47.At this moment, corresponding to linear velocity V, the coiling amount of waving roller 266 reduces gradually, for example becomes below the 10m/min from this linear velocity, corresponding to creep speed V13, waves roller 266 with predefined responsiveness control.Then, begin to detect the upper dead center of cut-out means 348, these cut-out means 348 reach upper dead center, just detect based on the pulse signal from the 4th pulse producer 372, and above-mentionedly wave the retreating position that roller 266 positions are defined in regulation.

Therefore, in the 14th embodiment, linear velocity is decelerated to just and stops, and can make homogenization heat time heating time of thin slice paper web 12a, finishes efficiently and removes the processing etc. of curling, and obtains and the above-mentioned identical effect of the 11st～the 13rd embodiment.And cut-out means 348 should be configured in upper dead center position usually, and precision is good and finish the cut-out operation of thin slice paper web 12a reliably.

In the present invention the 11st～the 14th embodiment, use thin slice paper web 12a to be illustrated as the thin slice body, but be not so limited, for example, also can be applicable to various thin slice bodies such as image recording medium such as heat sensitive paper, pressure-sensitive paper or the recording materials of taking pictures.

Shown in Figure 49 and 50, at the upstream side configuration detection of slitter 440 the 1st temperature sensor 474 in the surface temperature of the emulsion layer (image formation layer 412b side) of the hot display material 412 that is about to cut off, the 2nd temperature sensor 476 of the emulsion side surface temperature of the hot display material 412 that has just cut off in the downstream of transverse cutting unit 442 configuration detection simultaneously.As the 1st and the 2nd temperature sensor 474,476, preferably non-contact temperature sensor for example can use far infrared thermography device.

With the temperature information that the 1st and the 2nd temperature sensor 474,476 is measured, as shown in figure 50, import in the controller 478.The thermal source portion of controller 478 control warm-up mills 420, the mobile drive division that keeps roller 422, the thermal source portion of blowing out device 438,439, control is about to the emulsion side surface temperature of cut-out and the firm hot display material 412 that cuts off, so that enter the scope that Tg temperature (glass transformation temperature) is above and hot video picture temperature is following of image formation layer, preferably enter Tg to 100 ℃ scope, more preferably in (Tg+5) ℃ scope to 100 ℃.In this occasion, the unnecessary thermal source portion of warm-up mill 420, the mobile drive division that keeps roller 422, the thermal source portion of blowing out device 438,439 of controlling simultaneously can efficient be controlled at the said temperature scope best.

The heating arrangement of the knife edge part at least of heating slitter 440, transverse cutting unit 442 is set respectively, and when cutting off hot display material 412, the temperature of blade preferably reaches the identical temperature of emulsion side surface temperature with hot display material 412.Even do not reach and the identical temperature of emulsion side surface temperature, the blade temperature preferably enters the temperature range that Tg temperature (glass transformation temperature) is above and hot video picture temperature is following of image formation layer 412b at least.

As shown in figure 50, blade heating arrangement as slitter 440, for example, can adopt turning axle 444a, 446a with the 1st and the 2nd rotation blade member 444,446 constitute tubular, make the warm water made with thermal source feedway 480 or steam from the side inflow opposite side of above-mentioned turning axle 444a, 446a, be recycled to the structure of thermal source feedway 480.In addition, as the blade heating arrangement of transverse cutting unit 442, for example, can adopt and in the 1st and the 2nd blade member 460,462, bury underground or fixed heater 482, the structure that heats.And then, the far infrared thermography device of the blade temperature of measuring slitter 440, transverse cutting unit 442 is set respectively, its temperature control of measuring information input controller 478 and above-mentioned heating arrangement 416 be can be used as in the same manner the blade temperature control of shearing device 414.

In addition, about above-mentioned Tg,, under 50% relative humidity environment,, obtain Tg from its point of inflection in the hardness of all temps mensuration image formation layer 412b if be illustrated.In mensuration, usability optical material layer micro-hardness tester Fischer Scope H100VP, Vickers pressure head (136 ° at angle, opposite) are pressed into the Vickers pressure head to the degree of depth of the thickness 50% of image formation layer 412b and measure.In this occasion, must obtain the Tg of image formation layer 412b, therefore must make the non-image cambium layer on upper strata from image formation layer 412b demoulding.In addition, when image formation layer 412b is present in the two sides of support, obtain Tg separately, with a high side's Tg as the Tg that uses in the present invention.

The below explanation action of the shearing device 410 of formation like this.

At first, send and, before cutting off, heat from coiled material unloading part 413 with preheating apparatus 416 with shearing device 414 through the hot display material 412 that transfer path transmits.The degree of heat of the hot display material 412 in heating arrangement 416 is set in, when the cut-out of hot display material 412, make the emulsion side surface temperature of hot display material 412 enter the scope that Tg temperature (glass transformation temperature) is above and hot video picture temperature is following of image formation layer 412b, preferably enter more than Tg+5 ℃ and the scope below 100 ℃.

Thus, it is soft that image formation layer 412b becomes, and not have the fragility before the heating, and the film of the image formation layer 412b that causes in the time of therefore can preventing to utilize slitter 440, transverse cutting unit 442 cut-outs is peeled off, crackle and then peeling off from basalis 412a.In this occasion, it is identical with the emulsion side surface temperature of hot display material 412 that the blade temperature of slitter 440, transverse cutting unit 442 also reaches, and do not have the heat between hot display material 412 and blade to move, thereby be difficult to occurrence temperature distribution on hot display material 412, can cut off more well.

In addition, the upper limit of this heating is set in below the hot video picture temperature, best below 100 ℃, therefore do not damage the performance of taking pictures of the image formation layer 412b on the hot display material 412 yet.In addition, can prevent the heating-up temperature that too raises, and prevent image formation layer 412b from becoming too soft and be difficult to cut off.Thus, in the sword thing shape of not interdependent slitter 440, transverse cutting unit 442 or up and down under the regularization condition of blade, the film that image formation layer 412b does not take place is peeled off, crackle, obtains cutting off the effect of hot display material 412 well.

In addition, in the cut-out of hot display material 412, except to the heating of above-mentioned suitable temperature, preferably the thickness of image formation layer 412b is more than the 3 μ m and below the 30 μ m.This is because at the thickness of image formation layer 412b during less than 3 μ m, add the temperature of pining for image formation layer 412b and rise and accelerate, and the temperature 414 the way descends and becomes big from heating arrangement 416 to shearing device, is difficult to control the temperature of image formation layer 412b.

On the other hand, the have to temperature measuring of holding image formation layer 412b with the surface temperature of the emulsion side of measuring hot display material 412, therefore if image formation layer 412b surpasses 30 μ m and becomes blocked up, near near the surface of image formation layer 412b part and away from part just easily formation temperature distribute.Thus, all being difficult to of image formation layer 412b maintains above-mentioned temperature range equably, and this becomes when cutting off image formation layer 412b and produces that film is peeled off, the factor of crackle.

; for slitter 440; shown in Figure 52 and Figure 53; the the 1st and the 2nd rotation blade member 444,446 is rotated drivings, the above-mentioned the 1st and the 2nd and rotates the 1st of blade member 444,446 and contact at first with basalis 412a surface with the image formation layer 412b of 448,452 pairs of hot display materials 412 of the 2nd point of a knife, and the cut-out of above-mentioned hot display material 412 just begins.The the 1st and the 2nd rotation blade member 444,446 only overlaps with the depth of engagement H of mutual regulation, under the turning effort of the above-mentioned the 1st and the 2nd rotation blade member 444,446, forms rip cutting at hot display material 412 upper edge arrow directions Xs.

Then, for transverse cutting unit 446, the the 1st and the 2nd blade member 460,462 is towards Width (the arrow Y direction) configuration perpendicular to the transport direction (arrow directions X) of hot display material 412, and above-mentioned the 1st blade member 460 relative the 2nd blade member 462 move up and down.Therefore, shown in Figure 55 and Figure 56, the 1st and the 2nd point of a knife 464,470 Widths along hot display material 412 of the 1st and the 2nd blade member 460,462 begin contact image cambium layer 412b and basalis 412a, and hot display material 412 is carried out crosscut.Thus, thin slice 419 per 3 row form simultaneously, and transmit along the arrow directions X, pile up (as shown in figure 49) at thin slice stacking part 417 a piece number in accordance with regulations.

In this occasion, in transverse cutting unit 442, the value of the clearance C 2 of the 1st and the 2nd point of a knife 464,470 of 2 ° of the shear angle β of 3 ° of the point of a knife angle [alpha] of the 1st blade member 460, the 1st and the 2nd blade member 460,462 and the above-mentioned the 1st and the 2nd blade member 460,462 is carried out various variations, and estimate the experiment of the crackle 6 in top layer crackle 5, surface layer peeling 4 and the image formation layer 3 shown in Figure 64.It the results are shown in the table 7.Each assessment item " * " in the table 7, " △ " and " zero " are according to the metewand shown in the table 8.
