Fibers of improved quality can be produced with a reduced energy input in a device for producing synthetic materials which has a polymer melt feed leading to a rotating hollow reactor (1), the wall of which can be heated and which widens conically in order to guide a film melt towards an open side that can be closed with a lid (13), and which has ribs (4) for dividing the melt film into fibers that grow rigid after leaving the hollow reactor (1); and said improved quality can be achieved specifically in that the hollow reactor (1) is vertically oriented and exhibits a continuously curved inner wall and at the curved upper side exhibits an opening (3) for introducing the polymer melt, and in that a rotating distributor plate (12) is positioned opposite the opening (3), a slight distance from the inner wall of the hollow reactor (1).
A device for producing synthetic fiber materials, with a polymer melt feed leading to a rotating hollow reactor, whose wall can be heated and which widens conically in order to guide a film melt toward an open side that can be closed with a lid, and with ribs for dividing the melt film into fibers that grow rigid after leaving the hollow reactor, wherein the hollow reactor is vertically oriented and exhibits on its curved upper side an opening for introducing the polymer melt, while a rotating distributor plate is positioned opposite the opening, at a slight distance from the inner wall of the hollow reactor.
