An embodiment of the present invention will be described with reference to FIG. 1, which is a sectional view in the force direction. The straining roll 3 has a spiral protrusion 2 formed on the circumferential surface of a rod-like body and is rotatably disposed, and a presser roll 4 is provided below the straining roll 3 oppositely. A plurality of backup rolls 5 are arranged at predetermined intervals in the longitudinal direction of the presser rolls 4 (for example, two sets are arranged as shown in FIG. 2). Each set of backup rolls 5 is connected to a fluid pressure cylinder 6 via a bearing 9.
Each of the fluid pressure cylinders 6 is connected to a fluid supply source 10 via a selection switching valve 7 that selects the flow of fluid.

Only the backup roll 5 existing below is lifted up, and a uniform micro-strain can be applied to the steel plate 8 through the push-up roll 4 regardless of the meandering of the steel plate 8. In the present invention, in order to deal with the situation where the width of the steel plate 8 changes due to the weight of the presser roll 4 and the meandering of the sheet passing position makes it impossible to apply uniform strain, a backup roll group is used as shown in FIG. A pair of backup mechanisms 5A are provided on both sides of the presser roll 4 from other hydraulic or pneumatic pressure sources above the same part.
The pressure of the water pressure source is adjusted to provide a pushing force equivalent to the weight of the holding roll.
