 If the available length of conveying section to the molten film over the solid tail-back does not suffice, so the forced conveying of the solids remains up to the location where the first filling with melt took place. Principally, if the solid that holds a significantly larger speed component in the axial direction than the melt, reaches the melt filled area, and melt can penetrate in the cavities of the granules, then the forced conveying will collapse. In front of the location of the first filling up with melt, through a sufficiently large mass throughput, originates one with a granule filled screw area, in which, the granules rotate around the screw like in the figure. If the available length of conveying section to the molten film over the solid tail-back does not suffice, so the forced conveying of the solids remains up to the location where the first filling with melt took place.
