The utility model discloses a tension roll and coiled material that is suitable for. The tension roll includes first roller and second roller, the roll surface of two rollers is all including the tension face that lies in the middle part and the clamping face that lies in tension face both sides, and the regional roller diameter in first roller tension face place is cut thinly and is lighter than the regional roller diameter in clamping face place to the decompression groove of encircleing tension face is formed at the tension off -plate, the clamping face of first roller and second roller is relative each other. The coiled material is including lieing in middle effective coverage and lieing in the invalid region in effective coverage both sides, and effective coverage's width is less than or equal to the decompression groove width degree of first roller. Compared with the prior art, use the utility model discloses the coiled material of tension roll transmission can not produce the defect because of the structural plane that leads to having makeed with the contact of first roller.
