ABSTRACT:
Method and device in a cylinder dryer of a paper machine, in which a paper web is guided in connection with upper cylinders by using an upper wire and in connection with lower cylinders by using a lower wire. The wires are guided by faces of the respective drying cylinders and by guide rolls situated in spaces between the cylinders so that on an upper line of cylinders the web is pressed by the upper wire into direct drying contact with the faces of the upper cylinders, and the web is pressed by the lower wire into the faces of the lower cylinders in a lower line of the cylinders. In the method and in the device, the web is passed from one line of cylinders to the other over a certain distance as an open draw. A drying-air blowing is directed at the drying wires within an area of a line at which the respective drying wires are detached from the respective drying cylinders. By way of such blowings, a moist boundary layer which is derived from water diffused in connection with the wires and from the web to be dried, is disrupted.
