Position between above-mentioned two position applies and the second external force F2 with thickness direction component of the first external force F1 reversely, by
This execution make effective portion Gb in the width direction flexural deformation deformation assign process.The execution of process is assigned by the deformation, from
And expand the width in the gap being formed between effective portion Gb and non-effective portion Ga, thus avoid in the implementation procedure away from process
Effective portion Gb contacts with non-effective portion Ga.Effective portion Gb that deformation is assigned after process (away from process) be wound as reel and
As glass reels.
The ribbon glass film G for the object for turning into cutting in cutting separation circuit is wound as from by ribbon glass film G
The glass-film that the glass reels of shaft-like are continuously rolled out.Then, should using carrying mechanism (for example, ribbon conveyer etc.)
The ribbon glass film G directions rolled out are flatly carried by the direction shown in arrow T in Fig. 1.It should be noted that ribbon glass
Film G thickness is in the range of 200 μm~300 μm.
In cutting separation circuit, along as ribbon glass film G effective portion Gb and cutting for non-effective portion Ga border
Preset lines X is cut, the heating region H that is locally heated by the irradiation of laser is continuously formed and by refrigerant (example
Such as, vaporific water etc.) injection and the cooled region C that is partly cooled down.Thus, produced using the temperature difference due to two regions
Raw thermal stress continuously cuts ribbon glass film G, so that by ribbon glass film G effective portion Gb and non-effective portion Ga points
From.It should be noted that effective portion Gb and both non-effective portion Ga after separation are carried with status level side by side.
Here, in the present embodiment using the ribbon glass film G continuously rolled out from glass reels as cutting object,
But not limited to this.For example, as variation, the ribbon glass film G continuously shaped by glass tube down-drawing can also be regard as cutting
Object.In addition, be the mode for the ribbon glass film G cuttings that will flatly carry in the present embodiment, but as variation,
Can also cut the ribbon glass film G that inclined incline direction is carried along along scope with respect to the horizontal plane below 45 °
Mode.However, gradient with respect to the horizontal plane is the smaller the better, it is less than 20 ° preferably with respect to horizontal plane, more preferably

In away from process, in the effective portion Gb carried after isolation with status level side by side and non-effective portion Ga,
Effective portion Gb is flatly carried in continuation, and non-effective portion Ga from effective portion Gb transport path are pulled out downwards and are allowed to de-
From.Thus, make effective portion Gb and non-effective portion Ga remote in a thickness direction.
Here, making effective portion Gb after separation and non-effective portion Ga, remote mode is not limited to this implementation in a thickness direction
Mode as mode.For example, as variation, by banding while being carried along the incline direction being inclined relative to horizontal
Glass-film G cuts and makes in the case that effective portion Gb separates with non-effective portion Ga, to hold by following such mode
Row is away from process.That is, it can continue to along inclined direction carry effective portion Gb, and by non-effective portion Ga removing from effective portion Gb
Pull out and be allowed to depart from fortune path horizontal, so that effectively portion Gb and non-effective portion Ga is remote in a thickness direction.
Effective portion Gb during process is assigned for execution deformation, two of the lower surface Gbb by supporting effective portion Gb
Backing roll 1 applies the first external force F1 respectively, and passes through the air as fluid of the upper surface Gba injections towards effective portion Gb
A applies the second external force F2.Thus, the vicinity of two backing rolls 1 in effective portion Gb transport path, independent of deadweight
And make effective portion Gb forcibly flexural deformations in the width direction.Moreover, during effective portion Gb flexural deformations, making non-effective portion Ga
Depart from the execution of above-mentioned remote process from effective portion Gb transport path.
Intermediate calender rolls 2 are configured between two backing rolls 1,2 pairs of the intermediate calender rolls effective portion Gb's is sprayed by air A
The lower surface Gbb at position is supported, and is located at lower section compared with two backing rolls 1 to the height and position that effective portion Gb is supported.
In addition, when performing deformation imparting process, the non-effective portion Ga before departing from from effective portion Gb transport path is supported by roller 3.
Two backing rolls 1 and intermediate calender rolls 2 are configured in following location：Laser cutting method is performed from cutting separation circuit
Position (ribbon glass film G formation has heating region H and cooled region C position) along effective portion Gb transport path
The position of downstream side separation.It should be noted that from the position of execution laser cutting method to two backing rolls 1 and intermediate calender rolls
The stress that 2 distance is preferably set to act on effective portion Gb with effective portion Gb flexural deformation will not propagate to execution and swash
The distance of the position of optical cutting method.
Two backing rolls 1 are symmetrically configured on the basis of effective portion Gb width center Gbc, respectively to effective portion
The side of Gb width and the end Gbd of opposite side are supported.Thus, from two backing rolls 1 respectively to effective portion
Gb applies the first external force F1 (the effective portion Gb of supporting power).It is in strip that intermediate calender rolls 2, which are set to along effective portion Gb width,
Roller, and be set to the diameter roller smaller than two backing rolls 1.Two backing rolls 1 are set to free roll with the both of which of intermediate calender rolls 2,
Rotated by the friction with effective portion Gb.Also, two backing rolls 1 have shared rotary shaft 4 with intermediate calender rolls 2.
Air A sprays from air ejector 5 towards effective portion Gb width center Gbc.Thus, by A pairs of air
Effective portion Gb applies the second external force F2 (power for pressing effective portion Gb downwards).Width of the air ejector 5 in effective portion Gb
Direction center Gbc top is only configured with one.It should be noted that in the present embodiment, by the second external force F2 and
The first above-mentioned external force F1, effective portion Gb symmetrically flexural deformation on the basis of the Gbc of width center.
Roller 3 is set to the free roll that configuration rotates on the outside of width and around rotary shaft 6 relative to backing roll 1.Rotation
Axle 6 is configured in the identical height and position of rotary shaft 4 with two backing rolls 1 and intermediate calender rolls 2.In addition, the diameter of roller 3 is than supporting
The diameter of roller 1 is small, a diameter of identical size with intermediate calender rolls 2.Thus, in the effective portion Gb (ends supported by backing roll 1
Gbd between the non-effective portion Ga) and by roller 3 supported, difference of height is produced due to the difference of the size of the diameter between two rollers 1,3,
Therefore it is easier to avoid the contact between effective portion Gb (end Gbd) and non-effective portion Ga.
It should be noted that as shown in figure 3, in the case of two backing rolls 1 of main visual observation and intermediate calender rolls 2, will in
Between roller 2 top (position contacted with effective portion Gb lower surface Gbb) midpoint and backing roll 1 same effective portion Gb following table
The straight line that links of this 2 points of contact point of face Gbb contacts relative to the size of the inclined angle, θ 1 of horizontal line be preferably set to
In lower such scope.That is, if angle, θ 1 is too small, effective portion Gb will not fully flexural deformation in the width direction, so as to
It can not can fully expand the width in the gap being formed between effective portion Gb and non-effective portion Ga.On the other hand, if angle, θ 1
Excessive, then effective portion Gb of flexural deformation curvature becomes big in the width direction, is acted on effective portion Gb flexural deformation
The stress propagation of effective portion Gb to the possibility for the position for performing laser cutting method is raised.Therefore, angle, θ 1 is preferably 0.5 °
~5 °, more preferably 0.7 °~3 °, most preferably 1 °~2 °.
Here, in the present embodiment, by the way that the upper surface Gba as the air A of fluid towards effective portion Gb is sprayed,
So as to apply the second external force F2 to effective portion Gb, but it is not limited to this.As variation, can also by spray other gases,

Gb width center Gbc, as long as it is located at the position between two backing rolls 1 in effective portion Gb.Therefore,
As variation, the position injection air A that can also deviate towards the width center Gbc from effective portion Gb.Also, as
Variation, can configure multiple air ejectors 5, can be by multiple air ejectors 5 towards effective portion Gb multiple positions
(being located at multiple positions between two backing rolls 1) injection air A.In this case, effective portion Gb is applied with multiple
Second external force F2.
In addition, in the present embodiment, intermediate calender rolls 2 are set to roller in the width direction in strip, but not limited to this.It is middle
As long as roller 2 can be supported to the effective portion Gb lower surface Gbb by the air A positions sprayed.Therefore, as deformation
Intermediate calender rolls 2, can also be set to the roller in the width direction in short strip shape, only to by the lower surface Gbb at the air A positions sprayed by example
