PURPOSE: To prevent a beltlike matter from generating press marks caused by an edge breakage or a tension by guiding the whole width of beltlike matter by rolls larger in length than the width of the matter.

CONSTITUTION: Plural long rolls 4 longer than the width S of a strip are arranged at approximately equal angular intervals in the circumferential direction of an imaginary cylinder so as to be inscribed in the surface of the cylinder, in a fixed frame 7, and both ends of the rolls 4 are freely rotatably supported by bearings 6 mounted on the frame 7. The axial line of each long roll 4 is slanted leftward by an angle θ with respect to the axial line of imaginary cylinder in the top view, and the roll 4 is provided with a crown of the degree capable of preventing the strip S from causing scratches.
