Pressing roll device and pressing method

A pressing roll device, in which a unit cell passes between an upper roll and a lower roll, includes: the lower roll; the upper roll; a lower mount on which the lower roll is mounted and which is fixed in movement; an upper mount on which the upper roll is mounted and which is restricted by a bracket so as to ascend and descend by the bracket; and a stopper disposed between the lower mount and the upper mount so that the lower roll and the upper roll are spaced apart from each other.
