Abstract

Parent patent describes extruding plastic melt between two extrusion plates arranged so that toothed regions of one plate coincide with recesses in the other plate and vice versa. The plate oscillates in front of a fixed slot to which the melt is fed whereby to extrude longitudinal and transverse filaments forming a network. In the improvement the plates are fixed and connected to a feed duct through which melt is fed and each plate has an associated pref. cylindrical shutter which is selectively movable to block off the recesses or toothed regions to produce the same extruded network. Pref. the plates are circular and the teeth extend axially whereby a tubular network is produced and pref. the shutters have chamfered shuttering edges. Pref. one of the plates has a central aperture to which the feed duct is connected.
