Date Nov. 26, 1981.Cylinder dryer for a paper machine comprising a plurality of drying cylinders (10,20). The paper web and its lead strip are conducted between said cylinders (10,20) supported by a fabric (11). For guiding through the cylinder dryer the lead strip (L) having a width of a smaller order of magnitude than the normal width of the web (W), an air blowing means has been arranged adjacent to the drying cylinder and the free draws thereinbetween. Said air blowing means urges the web lead strip against the surface of the supporting fabric (11) or the cylinder. Said blowing means has substantially the same width as the lead strip and it carries a plurality of nozzles holes (14), through which air jets (F1,F2) are directed against the web. The covering angle of said air blowing means substantially equals that angle ( beta ) on which the web supporting fabric (11) and the web (W) on its outside change direction.</p> |
