In addition, laying 32 on metal tape 31 is due to for multilayer, as described later, by suitably setting each liner
The hardness (such as by making the laying 32a of inside soften, the laying 32b in outside being made to be hardened) of layer 32, in metal tape 31
Bending section (along the part of the outer peripheral surface of roller 3a3b) can be such that the cracking of each laying 32 is difficult to happen.As a result, previous
Difficult spacer technology is applied to metal tape 31 and is possibly realized, and such as present embodiment, laying 32 is arranged on metal tape 31
Composition is possibly realized.
In addition, being applied to the protective film of the polarizing film of for example large-scale liquid crystal display device in the optical film F that will be manufactured
In the case where, even if being had defect caused by the transfer of a little above-mentioned pinprick etc. (transfer defect) in optical film F, such turn
Print defect will not make the visuality for showing image be greatly reduced (this is because: the display area relative to image is all, by
Ratio to the display area of the image of the influence of transfer defect is small).On the other hand, it is applied to for example by above-mentioned optical film F
In the case where camera optical system (such as the infrared ray barrier film for being configured at the light incident side of photographing element), due to photographing element
Pixel is small, therefore above-mentioned transfer defect generates big influence to the camera shooting performance of photographing element.Therefore, it will be able to mitigate above-mentioned
For the composition of the present embodiment of the face quality deterioration of optical film F, optical film F is especially being applied to camera optical system
In the case of become highly effective.
In addition, constituting liner with the material harder than metal tape 31 in the composition for covering metal tape 31 with laying 32
Layer 32 is possibly realized.As a result, in the maintenance inspection of supporting mass 3, even if carrying out in the remaining glue of the surface of supporting mass 3 institute
In the case where the erasing cleaning for starching envelope, also it is difficult on the surface of supporting mass 3 (laying 32) with erasing defect.Therefore, long
It is possibly realized using supporting mass 3 to phase, can be improved the long-term operating adaptability (continuous production adaptability) of supporting mass 3.In addition,
Due to operating the raising of adaptability for a long time, the replacement frequency of supporting mass 3 is reduced, therefore great needed for the replacement of supporting mass 3
Cost, time are also cut down.
In addition, since the surface roughness Ra of the laying 32b on most surface layer is 3~200nm, for example thicker than the surface of SUS
Rugosity (such as 1nm or so) is sufficiently large, therefore becomes easy in removing from supporting mass 3 by the removing of mesh 5.Therefore, it is used for
The appropriate managerial (adjustment for especially reducing residual solvent amount exceedingly) of the residual solvent amount of the mesh 5 of removing becomes
It must be easy, the curling for easily mitigating mesh 5 and optical film F after removing as a result, is possibly realized.In addition, molten due to remaining
The appropriate managerial of dosage becomes easy, therefore for example becomes easy to make to remove, it is no longer necessary to not damage optical film F
It is taken a lot of time on the formulating that the mode of required function changes the volatility of rubber cement, in addition, also not needing to chase after
Add for making the equipment (such as cooling body of patent document 4) that becomes easy of removing, also no longer worry to be added as equipment caused by
Increased costs etc..
In addition, the manufacturing method of the optical film F of present embodiment is to manufacture optical film F using above-mentioned supporting mass 3l
The manufacturing method of optical film, comprising: be cast the rubber cement comprising the resin and solvent that constitute optical film F and shape on supporting mass 3
At the process (S2) of casting films (mesh 5), by process (S3) that casting films are removed from supporting mass 3 and make the casting films of removing
Drying obtains the process (S5) of optical film F.Seek needed for the replacement of supporting mass 3 thereby, it is possible to which supporting mass 3 is used for a long time
Cost is reduced, while can be manufactured face quality well and be crimped the optical film F mitigated.
[other compositions of supporting mass]
Fig. 6 is other sectional views constituted for indicating supporting mass 3.As shown in the figure, it is formed by metal tape 31
Multiple layings 32 can be 3 layers.In addition, though it is not shown, but multiple layings 32 can be 4 layers or more.Even if in the feelings
Under condition, due to being covered the surface of metal tape 31 with multilayer lining bed course 32, it can obtain: can reduce in metal tape 31
The face quality deterioration of optical film F caused by the transfer of pinprick existing for surface etc., the long-term operating that can be improved supporting mass 3 are suitable
The effects same as the effect of above-mentioned present embodiment such as conjunction property (continuous production adaptability).
In addition, leading to from 31 side of metal tape setting laying 32a, laying 32b, this 3 layers of laying 32c
3~the 200nm of surface roughness Ra for making the laying 32c on most surface layer is crossed, is removed in removing from supporting mass 3 by mesh 5
It becomes easy, the management of residual solvent amount becomes easy, therefore the curling for easily mitigating optical film F is possibly realized.
[hardness about each laying]
For each laying 32, as mentioned above, it is necessary, being respectively formed by using there is the glass processing of glass material.
The hardness of each laying 32 at this time is expressed as 500 or more and 700 or less with Vickers hardness.In addition, in each laying 32 by hard
Chromium plating or hard chromium come in the case where respectively constituting, the hardness of each laying 32 with Vickers hardness be expressed as 500 or more and
1200 or less.
Here, so-called Vickers hardness (being also sometimes denoted as " HV "), refers to following value: as illustrated in fig. 7, right
Pressure head P (the positive rectangular pyramids of diamond that 136 ° of diagonal (to face angle)) applies test force F (N), and pressure head P is pressed into metering object
OB, the catercorner length d (mm) of the pit of generated permanent deformation calculates contact area S when by removing pressure head P
(mm2), test force F is divided by the resulting value of contact area S.
In the present embodiment, for the hardness of the laying 32 on most surface layer, than the laying 32 relative to most surface layer
Hardness more positioned at at least one layer of laying 32 of 31 side of metal tape is high.For example, as shown in Figure 3, being arranged 2 on metal tape 31
In the composition of layer laying 32, hardness of the hardness than the laying 32a closest to metal tape 31 of the laying 32b on most surface layer
It is high.
In addition, for example, as shown in Figure 6, being arranged in the composition of 3 layers of laying 32 on metal tape 31, the liner on most surface layer
Hardness of the hardness than two laying 32a32b of layer 32c is high, can also with the 2nd close to metal tape 31 laying 32b
Hardness is identical, and the hardness than the laying 32a closest to metal tape 31 is high.In addition, the hardness ratio of the laying 32c on most surface layer
In the situation with high hardness of two laying 32a32b, the 2nd close to metal tape 31 laying 32b hardness than closest
The hardness of the laying 32a of metal tape 31 is high, can also be identical as the hardness of above-mentioned laying 32a.
In this way, by the hardness of the laying 32 on most surface layer (the hereinafter also referred to laying 32 in outside) become than relative to
The laying 32 on most surface layer is more positioned at (the hereinafter also referred to laying of inside of at least one layer of laying 32 of 31 side of metal tape
32) hardness is high, and the laying 32 of inside becomes softer compared with the laying 32 in outside.Even if as a result, metal tape 31 along
The outer peripheral surface of roller 3a3b is bent, and also the bending can be absorbed with the laying 32 of inside, so that above-mentioned laying 32 is difficult to out
It splits.Therefore, previous difficult spacer technology is possibly realized applied to metal tape 31, and laying 32 is arranged on metal tape 31, can
The above-mentioned effects such as the face quality deterioration of optical film F caused by the transfer of the pinprick on the surface of metal tape 31 etc. are mitigated by ground
It is possibly realized.
Particularly, most surface layer laying 32 hardness than (connecting with metal tape 31) lining closest to metal tape 31
In the situation with high hardness of bed course 32, since the laying 32 to connect with metal tape 31 is softer, can with metal tape 31
The laying 32 to connect expeditiously absorbs the bending of metal tape 31.As a result, it is possible to reliably mitigate above-mentioned laying 32 and
The cracking of the laying 32 on its upper layer.Therefore, it such as present embodiment, reliably obtains realization and multiple linings is set on metal tape 31
The composition of bed course 32 and mitigate the face quality deterioration of optical film F etc. above-mentioned effect be possibly realized.
In addition, in the case where being processed by hard chrome plating to form multilayer lining bed course 32 (in multilayer lining bed course 32 by hard
In the case that chromium plating is constituted), the hardness of the laying 32 on most surface layer is expressed as 500 or more with Vickers hardness, the Vickers than SUS
Hardness (200 or less) high 2 times or more.Therefore, it becomes difficult to which the laying 32 on most surface layer has as caused by external factor
Defect, particularly, in the maintenance inspection of supporting mass 3, even if in the case where wiping rubber cement envelope with rag, it is also difficult to
The laying 32 on most surface layer is with erasing defect.In addition, also can inhibit the bearing as caused by solvent by above-mentioned laying 32
The corrosion on the surface of body 3.Thus, it is possible to reliably improve the long-term operating adaptability of supporting mass 3.
[the distinctive composition of glass liner]
It is formed on metal tape 31 by glass processing in the composition of multilayer lining bed course 32, preferably the laying on most surface layer
32 surface roughness Ra is 30~100nm, the hardness of the laying 32 on most surface layer with Vickers hardness be expressed as 500 or more and
700 hereinafter, the thermal conductivity of multilayer lining bed course 32 (laying is all) is 0.8~1W/mK.
Surface roughness Ra by the laying 32 on most surface layer is above range, netted with directly being supported with metal tape 31
The composition of object 5 is compared, and can reliably be reduced mesh 5 for the adaptation of supporting mass 3, reliably be improved the stripping of mesh 5
From property.The appropriate managerial for the residual solvent amount of the mesh 5 of removing becomes easy as a result, can easily mitigate removing
The curling of mesh 5 and optical film F afterwards.
In addition, since the hardness of the laying 32 on most surface layer is expressed as 500 or more and 700 or less with Vickers hardness, compares SUS
Vickers hardness (200 or less) high 2 times or more, therefore in the same manner as the situation of hard chrome plating, the laying 32 on most surface layer is difficult
To have the defect as caused by external factor, even if being also difficult in laying 32 with by rag institute in maintenance inspection
Caused erasing defect, the corrosion on the surface of supporting mass 3 as caused by solvent are also suppressed.Thereby, it is possible to reliably mention
The long-term operating adaptability of high supporting mass 3.
In turn, the thermal conductivity of multilayer lining bed course 32 be 0.8~1W/mK, such as with SUS (thermal conductivity: 40W/mK) phase
It is smaller than very.Thereby, it is possible to inhibit drying of the mesh 5 on supporting mass 3.Therefore, even if changing without rubber cement formula, benefit
With the external temperature management of additional equipment, being also able to suppress the residual solvent amount in removing is exceedingly reduced.As a result, it is possible to
Prevent the lateral ends due to mesh 5 compared with lateral center portion the dry influence quickly carried out and in 5 (optics of mesh
Film F) end crimp.Therefore, it for the optical film F of the dry film for being particularly easy to carry out, sets as described above
The composition of the thermal conductivity of multilayer lining bed course 32 becomes highly effective.

< evaluation method >
(the face quality of optical film)
Visually to observe the film surface of manufactured optical film, the pinprick present in the metal tape of supporting mass and welding are judged
Whether the transfer defect of line exists in film surface, is based on evaluation criterion below, evaluates the face quality of optical film.
" evaluation criterion "
Zero: transfer defect is absolutely not observed in film surface.
×: considerable transfer defect is observed in film surface.
(operating adaptability (continuous production adaptability) for a long time)
Before and after carrying out wiping cleaning with surface of the rag to upper layer (supporting mass 1~8) and metal tape (supporting mass 9),
It is observed with the illumination of the LED light (ト リ ト Application グ リ ー Application, NCC are manufactured) of hand held, investigating the defect after wiping cleans, (erasing lacks
Fall into) state.Then, it is based on evaluation criterion below, is evaluated for operating adaptability for a long time.
" evaluation criterion "
Zero: on supporting mass surface almost without erasing defect is observed, not needing replacement supporting mass.
△: observing some erasing defects on supporting mass surface, be even if be needed on film on quality almost without influence
Shallow defect does not need replacement supporting mass.
×: the big erasing defect for the degree for leading to quality deterioration when being needed on film is observed on supporting mass surface, is needed
The replacement of supporting mass.
(curling)
The optical film of manufacture is placed on flat face, by the lateral ends of metal ruler aligning film, from metal
The scale of the ruler of system reads the float-amount from the film lateral ends of mounting surface, using the value of reading as amount of curl.Then, base
In evaluation criterion below, curling is evaluated.
" evaluation criterion "
Zero: being crimped in film lateral ends, but be on the conveying of film thereafter almost without the curling of the very little of influence.
△: crimping in film lateral ends, but not generate the curling of the degree of obstacle to the conveying of film thereafter, real
With no problem.
×: in the big curling for the degree that film lateral ends cause conveying to stop.
In table 3, the result of the measurement result of each parameter and the evaluation of each supporting mass is shown.
According to table 3, in supporting mass 1~7, face quality, curling, the evaluation of long-term operating adaptability all good (zero
Or △).It is thought that due to: in supporting mass 1~7, since multilayer lining bed course is located on metal tape, in the system of optical film
When film, transfer of the shape of the pinprick existing for the surface of metal tape and sealing wire to mesh is prevented from, in addition, due to liner
The presence of layer, it becomes difficult to erasing defect.In turn, it is believed that reason is: due to the table of the laying (upper layer) on most surface layer
In the range of surface roughness Ra is 3~200nm, therefore the fissility of mesh improves, and is able to carry out the mesh for removing
Residual solvent amount appropriate managerial (adjustment for especially reducing residual solvent amount excessively).
Particularly, in supporting mass 2,4~7, since the hardness of the laying (upper layer) on most surface layer is indicated with Vickers hardness
It is 500 or more, the hard 2 times or more of laying ratio SUS, on supporting mass surface, (laying surface) is difficult to have to be cleaned by wiping and be drawn
The erasing defect risen, as a result, thinking that the long-term operating adaptability of supporting mass further increases.
In addition, in supporting mass 3~6, due to the range that surface roughness Ra is 30~100nm, for the net of supporting mass
The fissility of shape object becomes the range (since removing does not become difficult exceedingly, also not becoming easy exceedingly) of appropriateness,
Therefore the appropriate managerial of the residual solvent amount of mesh becomes easy really, as a result, thinking the curling of the lateral ends of film
Inhibited well.
Relative to above content, in supporting mass 8, due to being provided with laying, the face of optical film on metal tape
Quality and the long-term operating adaptability of supporting mass become good.But due to the rough surface on the laying on most surface layer (upper layer)
Spending Ra is more than 200nm, and mesh excessively becomes easy from the removing of supporting mass, therefore is difficult to carry out the tune of residual solvent amount instead
It is whole, as a result, thinking to generate curling in film end.
In addition, in supporting mass 9, it is all bad (×) for the result of face quality, long-term operating adaptability and curling.
In supporting mass 9, it is believed that: due to being not provided with laying on metal tape, the pinprick etc. of metal tape is needed on netted
Object, in addition, directly having erasing defect on the surface of metal tape.In addition, due to the surface roughness Ra of metal tape it is small up to 1nm,
Mesh is easy to be sealed at supporting mass, therefore the residual solvent amount of mesh excessively reduces on supporting mass, as a result, thinking film
Lateral ends become easy dry and crimp.
