Drying device for material webs, z.b.von paper

摘要

The present invention relates to a drying apparatus of the materials in sheet form. & br / this apparatus essentially comprises a first fixed cylindrical surface (5) into which opens (8) a supply of combustible gas, a second fixed cylindrical surface (6) on the outside which is concentric with the first and defining with that - latter, a distribution chamber (7) of the fuel gas, and an ignition system of the fuel gas passing through the second surface (6) on which is fastened the flame so that this surface is heated to a very high temperature and the place of the heat radiating in the annular space (14) between said second surface (6) and a rotary cylinder (2) on which is applied to the material to be dried. & br / this apparatus makes it possible, in particular, the rapid drying, homogeneous and effective use of sheets or strips of paper.
