Abstract
Method for the cleaning of spinning devices with a plurality of spinning apertures for the output of molten plastic. With the spinning device in operation, individual dirt-contaminated and/or clogged spinning apertures are closed with plugs, these plugs-consisting of at least in part of at least one oxidizable substance. The spinning device is subjected in the course of its cleaning to a pyrolysis treatment for the breakdown of residual plastic. The spinning device is subjected to an oxidative treatment, so that the oxidizable substance is oxidized.
