ABSTRACT:
A spin blowing apparatus for producing spun fleece of thermoplastified synthetic resin provides that the spinneret plate and/or the fiber or filament blowing gap through which the blowing air/fiber mixture passes downwardly and/or the air flow resistance of the perforated belt upon which the fleece is collected can be varied in response to measured values of the specific weight and/or air permeability of the web to restore any deviation of the latter.
