Further, the invention concerns an after-dryer for a paper machine for applying the method to the drying of a surface-treated paper web or equivalent, which after-dryer is placed after the finishing device (10), by means of which finishing device (10) the paper web (W) is surface-sized or coated. The after-dryer comprises at least one dryer group that applies single-wire draw, and an impingement-drying equipment (25) is fitted in connection with at least one cylinder or roll (23, 24) in said dryer group. |
