| 摘要 |
<p>The invention relates to a method for cleaning a filter (21) on a draw frame and a draw frame for drafting one or more slivers (FB) and having a controller (13) for controlling work processes of the draw frame (1) and having an exhaust system (3) for exhausting dust and/or dirt particles released during work processes, the exhaust system (15) comprising an exhaust fan (17) for generating a suction flow (S) and a filter (21) for filtering out dust and/or dirt particles from the suction flow (S). The invention proposes that a dirt collecting surface (31) of the filter (21) upstream with respect to the suction flow (S) is associated with at least one blast nozzle (32) supplied with compressed air for generating a cleaning flow (R) flowing along the dirt collecting surface (31) of the filter (21).
