ABSTRACT:
Scraping agents such as silicone oils are applied, preferably continuously, to the circumference of the spinneret between the outer edge and the spinning holes nearest to it. Application is effected by means of a ring of an absorptive, surface active material, e.g., a ring wick located in a groove or a ring chamber which may be fitted with feed lines to supply the scraping agent.
