Abstract
A calender has at least four rollers that are located one above the other. The rollers rotate about roller bearings. The calender is located within a paper-making machine. Each of the rollers is rotatably driven by an independent driving mechanism. At least two of the rollers are heatable. At least 40% of the rollers are soft rollers. The outer coverings of the soft rollers are made of a synthetic material that is not sensitive to marking so that a doctor blade can be applied to the soft rollers. The calender includes a device that inserts a paper guide strip into the calender.
