Abstract

Wide-slot die for an extruder used in mfr. of thermoplastics profiled film as used in prodn. of laminated safety glass, is provided with profiles near its discharge edge. The profile consists of flutings or milled edges which periodically (sic) widen the die slot immediately at the discharge edges of the die lips. The flutings or milled edges are alternating recesses and teeth lying close together. They may be arranged at exchangeable die lips. The recesses are 0.1-1 mm pref. 0.1-0.5 mm deep and spaced 0.2-1 mm pref. 0.3-0.5 mm from one another. The profiling of the die slot is integral, so there is no need to use special, separate, devices for shaping the extruded film.
