Abstract
The object of the invention is an apparatus and a method for improving the detachment of paper () from the cylinder of a paper machine in a drying section implemented with a single wire transfer, which drying section comprises means for heating the paper on the drying cylinder () and for transporting it onwards on the wire () via a hitch roll () to the next drying cylinder such that the paper together with the wire in the section between the cylinders is sucked against the wire by means of low pressure. What is essential to the invention is that in order to improve the detachment of the paper () an apparatus is installed on the opposite side of the drying wire () at the detachment point (), which apparatus comprises a nozzle (), with which an air jet () is blown against the direction of travel () of the drying wire, and a carrying surface () such that the air jet () ejects secondary air () along with it causing an air flow () between the planar carrying surface () and the drying wire ().
