摘要

The melt spinning and depositing of synthetic filaments for the production of non-woven, comprises extruding and stripping the filaments by nozzle plates with nozzle holes arranged next to each other to form filament groups (4.2), which are deposited side by side to separate non-woven webs (5.1, 5.2), and depositing the non-woven webs parallel with one another on a deposition band (1) with an interval in production width of 2-6 m. The non-woven webs are strengthened and rolled up for subsequent treatment. The nozzle plates are held by spin-die-manifolds (7.1, 7.2) arranged side by side.

The non-woven webs are strengthened and rolled up for subsequent treatment. The nozzle plates are held by spin-die-manifolds (7.1, 7.2) arranged side by side. The spin-die-manifolds are jointly or separately provided through a melt source with polymer melts. An independent claim is included for a device for melt spinning and depositing of synthetic filaments.
