- the speed measuring device 32 for measuring the speed need not be provided.
- the target rolls not only the comparison of the rotation degree between the guide roll 14 and the reference roll 10 but also the rotation of the guide roll 14 and the guide roll 13 close to this, for example, The relative speed ratio may be measured.
- the float amount detector 1 as a float amount detecting means for detecting the float amount of the web 2 from the roll surface of the guide roll 14 3, and the amount of slip of the web 2 with respect to the guide roll 14 is measured based on the detected amount of float of the web 2 (see the following formula 3).
- a non-mechanical laser sensor is used for the floating amount detector 13 2, and a change in the separation between the roll surface and the web 2 is measured.
- the change in the separation between the roll surface and the web 2 has a relative relationship with the “slip” of the web 2 with respect to the guide roll 14, and the separation between the mouth surface and the web 2 exceeds a predetermined value. Then, the same phenomenon occurs as the web 2 slides against the guide roll 14. Note that the reason why the separation between the roll surface of the guide roll 14 and the web 2 is reduced is that the conveyance speed of the web 2 is fast and the separation air between the low surface and the web 2 is mixed in. Can be considered.
- the encoder 34 for measuring the rotation of the guide roll 14 may not be provided as in the first embodiment and the second embodiment described above.
- the correlation table 3 5 indicating the relationship of the tension T of the web 2 to the slip amount W of the web 2 in advance for each carry degree V (—definite) of the web 2.
- the contents of the correlation table 35 and its method are not limited to this.
- the web with respect to the slippage W of the web 2 It may be a correlation card that shows the relationship between the two carrier Vs.
- the transport speed is set to a target transport speed, an ideal thigh speed, or the like.
- each roll structure of the transport line 1 is not particularly limited, for example, a nip roll! ⁇ Bridal rolls may be provided.
- Each measuring instrument is not limited to the configuration described above.
- the web 2 conveyed to the thigh line 1 is not limited to an electrode (sheet) but may be any long object that can be continuously conveyed.
- Industrial applicability INDUSTRIAL APPLICABILITY The present invention can be usefully applied to a long object such as an electrode thigh (conveyance control when linking to a web or the like) with respect to a roll provided in a conveyance line.
