When the strip S is cut by the shear 1, 1. The strip S is pulled in the line direction by a slight force by the shearing device, causing the line tension to fluctuate. For this reason, the strip S is e.g.
When this strip is supported by a large deflection angle l710-le, the fluctuation condition t and therefore E) IJ
Surface defects such as roll marks occur on the knob S.・For this reason, conventionally, controlling the rotating parts such as the pinch roll 2 by suppressing the rotational force (force;, soσ) was extremely complicated and extremely difficult.

下可動ロール5を配設したものである。FIG. 2 shows an example of the improved shear line arrangement according to the present invention, in which 1 is a shear, 2 is a pinch roll, 3 is a measure roll, and 4 is a leveler roll. In the present invention, the strip S and the deflector amount are A vertically movable roll 5 of a spring type or the like that can move vertically is disposed downstream of a fairly large roll, for example, a leveler roll 4.
