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 back-up rolls 5 are arranged side by side at predetermined intervals in the longitudinal direction of the presser roll 4 (for example, two rolls are arranged as shown in FIG. 2). Each set of backup rolls 5 is connected to a fluid pressure cylinder 6 via a bearing 5A, and a selection switching valve 7 is provided for selecting a fluid flow for each of the fluid pressure cylinders 6. It is connected to the fluid supply source 10 via.

Note that the pressure source can be adjusted to the required pressure necessary to obtain the required straining force, and the steel plate 8 is passed between the straining roll 3 and the presser roll 4. Then, depending on the meandering position of the steel plate 8 during threading, only the selection switching valve 7 corresponding to the back-up roll at the position where the steel plate 8 is present is selectively energized. Only the back-up roll 5 is pushed up, and a uniform micro-strain can be imparted to the steel plate 8 via the push-up roll 4 regardless of its meandering.
