FIBRILLATION APPARATUS FOR POLYMERIC FIBER FILAMENT AND FIBRILLATION

摘要

PROBLEM TO BE SOLVED: To obtain a homogeneously fibrillated reinforcing substrate by continuously inserting and passing polymeric fiber filaments through the interior of a rotatable container filled with a group of balls for kneading. ;SOLUTION: Polymeric fiber filaments 3 such as aramid fibers delivered from a drum 21 are introduced through a filament carrying in means 23 from a filament inlet 7 into a rotatable container 13 filled with a group of balls 11 for kneading, passed therethrough in a state of the filaments embedded in the group of the balls 11 with filament, guides 15 and then inserted and passed from a filament. outlet 9 so as to be deliverable with a filament taking out means 25. Container driving means 19 are subsequently operated to continuously fibrillate the surfaces of the running polymeric filaments 3 while making the group of the balls 11 perform a kneading motion. The fibrillated filaments 3 are successively cut to specified dimensions with a filament cutting means 29.;COPYRIGHT: (C)2000,JPO
