Abstract (en)
[origin: EP1420089A1] The spinneret as a melt-blow jet head (1), for melt spinning thermoplastic filaments, has at least one channel (3) for the molten flow. The jet (2) has at least one row of jet channels (5) with outflow openings (6) at the outflow end (4). Drillings (10) are at the jet outflow end, each with a shaped body (11) in a positive fit, to form a jet channel between the body and the drilling. Flow channels (7) for compressed air are aligned at the jet outlet.
