Power more effectively reduces the tension of the web on processing work platform 20.In counter-rotating, can also from processing work platform 20 into
The frictional resistance between processing work platform 20 and web U is eliminated in row air blast.Alternatively, it is also possible to replace from supporting table 23 into
Row air blast, by make supporting table 23 become such as Fig. 2 (b) or (c) shown in construct, to reduce supporting table 23 and width
Frictional resistance between material U reduces the tension of the web on processing work platform 20.After 7 counter-rotating slight distance of suction roll, open
The attraction of beginning processing work platform 20, makes web be maintained on processing work platform 20.In this stage, work can also be processed
The positioning in the Y-direction of platform 20/directions θ.Become as a result, almost without tension force effect on being processed the web that workbench 20 attracts
State.
Fig. 3 (d) is to make processing head while processing work platform 20 and attraction workbench 22 are attracted in the process segment
21 decline, and desirable processing is carried out to web.As a result, due to being processed to the web implementation almost without tension force effect,
It can inhibit the generation extended so that high-precision to be processed into possibility.In processing, workbench 22 is attracted to continue to attract
The reasons why be, in order to prevent since compensating roller 6 is along with the continuous transmission carried out in supply platform S1 and towards upstream side low speed
Tension change acts the web in processing caused by mobile.

While 22 progress air blast, air blast is carried out from supporting table 23, discharges web.After this, suction roll 7 is made to rotate in the forward direction small
Length (such as 0~0.2mm).The small degree of the suction roll 7, which rotates in the forward direction, is arbitrary operation.This operation is in order to processing
Tension is previously applied in web on workbench 20, is led after inhibition since suction roll 7 rapidly rotates in the forward direction (with reference to Fig. 3 (a))
The vibration of the web of cause.After this, the 1st procedure (Fig. 3 (a)) is returned to, repeats same process later.
Fig. 4 (a), Fig. 4 (b) indicate the tension variation of existing transmission device and web in the transmission device of the present invention.Such as
Shown in Fig. 4 (a), also there is the tension T1 generated by dance roller in existing transmission device, in processing, at the moment
T7 process finishings, indexing transfer start.When indexing transfer, web is temporarily acted on by larger tension T2, which exists
Below the elastic limit of web.T8 at the time of after indexing transfer, the tension of web are only to become again for tension T1, can not
Become 0.Web is processed in the state of having acted on tension T1.
In the present invention, as shown in Fig. 4 (b), start to release attraction in moment t1, tension T1 is acted in web.When
T2 is carved, since indexing transfer starts, tension T2 is acted in web.In moment t3, indexing transfer terminates, and tension becomes again as tension
T1.Then, after moment t4 carries out low-tension operation, tension is reduced to about 0, implements processing from moment t5 to moment t6.
By carrying out low-tension, to which the tension of the web on processing work platform is about 0.Implement to add by the web to the state
Work makes high-precision to be processed into possibility.Repeat similarly to operate after this.
In addition, will attract for the difference of the clear present invention and the prior art in Fig. 4 (b) and release, stop, low-tension
Each period indicate long, actually attract release, stop, low-tensionization pole compared with process time of each period
It is short, therefore need not worry by attracting releasing, stopping, each operation of low-tension that process time is caused to be affected.
