Claims

[Scope of utility model registration request]

In a device that presses a pressing roll against a heating drum, the pressing roll is divided in the longitudinal direction, each divided roll is connected by a shaft joint and a shaft, sprockets are attached to both ends of the connected roll group, and the other heating drum is heated. A pressure roll rotation drive device characterized in that the rotational drive force of a drum is received by the same sprocket and each roll is rotated at a constant speed.
