Abstract
The gap adjusting device for nipping rollers is provided with one roller rotatably provided at a prescribed position and the other movable roller. The nipping rollers are adapted so that the other roller is capable of forcing a paper web passing between the two rollers onto the one roller. A nipping-roller gap adjusting device includes a pair of supporting arms, one end of each of the supporting arms being swingably supported and the other end thereof rotatably supporting the other roller. A pressing force imparting device gives to the support arms a force working in such a direction that causes the other roller to approach the one roller and which, at the same time, can adjust the magnitude of the force. A minimum gap setting device can set a minimum gap between the one roller and the other roller. A gap adjusting device adjusts the size of a gap between the one roller and the other roller. A fixed frame member rotatably supports the one roller. The gap adjusting device is mounted on the fixed frame.
