Abstract
A single facer comprises an apparatus for automatically adjusting a gap between rolls, i.e., an apparatus for maintaining a roll gap constant. The apparatus for adjusting the distance between the centers of the roll shafts is operable to move one roll toward the other by actuating driving means. The driving means is controlled in response to the variation in the temperature of the frame which supports the driving means of the roll in place, or to the passage of time after a heating mechanism for heating the rolls has started operation.
