[origin: WO9812380A1] The invention concerns a method for drying a surface-treated paper web or equivalent in an after-dryer of a paper machine, in which method the paper web (W) is first finished in a finishing section, in which finishing section the paper web (W) is surface-sized or coated by means of a finishing device (10), after which the paper web (W) is dried. In the after-dryer the paper web (W) is dried in at least one dryer group that makes use of single-wire draw, and that, at the same time, the paper web (W) is dried by means of an impingement-drying equipment (25) fitted in connection with at least one cylinder or roll (23, 24) in said dryer group. 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.
