PURPOSE: To provide a thickness profile control unit and a calendering unit capable of making paper of advantageous quality in printing after delivered as a product and preventing the welt and blister formation in the roll paper.

CONSTITUTION: A thickness profile control unit and a calendering method characterized by controlling a thickness adjusting unit so as to have a uniform deviation of a profile which is derived by adding up three profiles which are derived by multiplying a factor A by a weight profile of raw paper, a factor B by a weight profile of coating and a factor C by a thickness profile (where, factor C/factor A< factor B/factor A<1.0).
