Abstract

PURPOSE:To eliminate defective feeding to a cutter and to chip readily extrudate of melted polymer, by extruding molten polymer successively from the die having many nozzles and leading it to the cutter. CONSTITUTION:In the process wherein strands are led to cutter 9-12 and made into chips after molten polymer is extruded to form the strands successively from a die 3 having many nozzles 4, the opening speed A of the plate 15 closing the front of the die is adjusted so as the ratio of the proceeding speed of the cooled strands B to the opening speed A (B/A) is adjusted to 2-7 and the time of extrusion commencement from each nozzle 4 is successively put back. Thus, the tip parts 2 of the extruded strands are fixed in a successively shifted state and led to the cutter 9-12.
