Spinneret for molding thin filmlike material

Abstract

Abstract PURPOSE:To obtain a thin filmlike material having plural fine unit strips of different characteristics arranged repeatedly in parallel plural times, by spreading differenet kinds of polymers on a plate, and redividing the polymers, arranging and positioning the polymers, and arranging and positioning the polymers in one straight line or on the circumference of a circle. CONSTITUTION:A plate (A)6 is placed on a plate (B)7, plate (C)8, plae (D)9 and spinneret nozzle 3 on top of each other, and contained in a space between the upper presser 1 and the lower presser. The plate (A)6 is preforated with communicating holes (6a), (6b) and (6c) for feeding polymers, which are distributed at a given interval with the plate (B)7. Plural kinds of polymers extruded in plural rows at a regular interval are arranged in one row with the plate (C)8, passed throgh slitlike openings (10a), (10b) and (10c) of the plate (D)9 and extruded through a slitlike nozzle 11 in the form of a thin film.
