Abstract

A process for melt spinning products in the form of a thread, tape or film starting from a thermoplastic and thread-forming substance, a substance that is melted and then forced to pass through a mixing zone, a filtration zone and a molding device, the product thus extruded being finally cooled and collected; characterized by the fact that in the mixing zone the melt stream is divided several times, in a known manner, into sub-currents, by stationary guide means, and by the fact that after each division the sub-currents, at the same time that they are displaced relative to each other and possibly deformed, they are partially reunited before dividing them again, after which all the subcurrents finally reunite.
