<p>Apparatus for producing spunbonded fabric from aerodynamically stretched thermoplastic filaments comprises a spinneret (1), a cooling chamber (2), into which cooling air is fed from a feed chamber (8), a stretching unit (4) with stretching channel (5) and a moving wire (7) , on which the fabric is laid down. The air feed chamber consists of two sections (8a, 8b), through which air at different temperatures is fed.</p> |
