Foraminal apparatus for splaying and depositing nonwoven filamentary structures

Abstract

Abstract BETWEEN THE TWO OPPOSING SURFACES. THE TWO OPPOSING SURFACES OF THE SPLAYING DEVICE HAVE CONTINUOUS SURFACES OF CURVATURE WHICH SURFACES EXHIBIT A CONVERGING TO DIVERGING PATTERN AS THE OPPOSING SURFACES EXTEND FROM THE EXIT OF THE ASPIRATOR. THE FORAMINOUS SPLAYING DEVICE IS POSITIONED NEAR THE EXIT OF AN ASPIRATOR SO AS TO SPREAD THE FILAMENTS IN SUBSTANTIALLY ALL DIRECTIONS AND THEREBY TO PROVIDE GREATER OPENNESS AND GREATER RANDOM LAYDOWN OF FILAMENTS. AN APPARATUS FOR AUGMENTING DISPERSAL AND IMPROVING DEPOSITION OF A PLURALITY OF CONTINUOUS FILAMENTS ONTO A CONTINUOUSLY MOVING SURFACE WHEREBY RANDOM DISTRIBUTION OF THE FILAMENTS IS PROVIDED FOR HE PRODUCTION OF UNIFORMLY DISTRIBUTED NONWOVEN WEBS. SUCH APPARATUS COMPRISES A FORAMINAL SPLAYING DEVICE HAVING TWO OPPOSING SURFACES WITH HOLES EXTENDING THROUGH AT LEAST ONE OF THE TWO OPPOSING SURFACES. COMPRESSED GAS, E.G. AIR, IS DISCHARGED THROUGH THE HOLES IN SUBSTANTIALLY PARALLEL COLUMNS SO AS TO INTERPENETRATE A FILAMENT BUNDLE PASSING
