Abstract:
A nip roller includes a core material having a surface coated with rubber. The nip roller having a support length L1 of 5 m or longer. The rubber surface has a hardness H (deg) equal to or lower than 65 deg as measured by a JIS K6253 Type A durometer (A type). Mass W (kg) of the nip roller and second moment of area I1 (m4) and the Young's modulus E1 (Pa) of the core material satisfy E1I1/W≥80000.
