ABSTRACT:
In the dryer section of a paper making machine, the paper web is pressed against the drying cylinders by means of an air-permeable endless support band. An air blast apparatus extends transversely of the paper making machine and creates an air flow which is directed generally across and through the support band and onto the paper web. The air blast apparatus has at least one blow orifice in the form of a ring slot with two longitudinal slots extending generally longitudinally of the air blast box or housing of the air blast apparatus, and at least generally transversely of the paper web and the support band. The blowing directions of the two longitudinal slots may be at different angles with respect to the running direction of the support band.
