Abstract

A paper drying cylinder or roller (1) for paper mills, said cylinder or roller rotating about a rotating shaft (2) on bearing elements (2') of a framework (30) that holds at opposite sides the rotating shaft (2). In particular, the paper drying cylinder (1) rotates within the structure of two drying hoods (4, 5) that remove the moist air stream that forms while the continuous paper web is dried. The active surface of the Yankee cylinder (1) is cylindrical surfaces (1'), whereas the head walls (3) does not have any function related to paper drying but, on the contrary, are heat loss surfaces. According to the invention, a protection carter (40) is provided arranged about the rotating shaft (2) proximate to one of the head walls (3) that are connected to the framework (30) in such a way that the carter (40) during the rotation of the paper drying cylinder (1) stays motionless and faces the head wall (3) carrying out a thermal insulating function. This way, heat loss towards the environment and the steam consumption to heat cylinder 1 is reduced.
