Circular type tension applying apparatus for slit band plates

Abstract

A circular type tension applying apparatus for slit band plates comprises a plurality of pairs of upper and lower endless belts for interposing the respective slit band plate, an upper pressure applying member for allowing the upper endless belts to rotate and for applying pressure to the upper endless belts, and a lower pressure applying member for allowing the lower endless belts to rotate and for applying pressure to the lower endless belts. Each of the endless belts is able to rotate independently and circularly, and an outer surface of the endless belts being larger in friction than an inner surface of the endless belts. Both of the upper and lower pressure applying members are substantially circular in section. Furthermore, the endless belts have sufficient compressibility and restoration force in thickness direction so that tension is generated by resistance force from a deformation by compressive strain of the endless belts.
