Claim 1
Independent Claim
102 words
A PROCESS FOR PREPARING A FLEXIBLE SHEET OF APERTURED NON-WOVEN FABRIC WHICH COMPRISES SATURATING A FLEECE OF UNSPUN TEXTILE-LENGTH FIBERS WITH A LIQUID LUBRICANT THEREFOR, CONTINUOUSLY CONVEYING SAID SATURATED FLEECE OVER A PATTERNED SURFACE OF LANDS AND INTERCONNECTED GROOVES, SAID PATTERNED SURFACE MOVING WITH SAID FLEECE, SUBJECTING SAID FLEECE TO REPEATED MECHANICAL VIBRATORY IMPACTS FROM A SOLID, PLAIN-SURFACED RESILIENT ELASTIC PADDLE, SAID IMPACTS BEING SUBSTANTIALLY NORMAL TO THE DIRECTION OF TRAVERSE OF SAID SATURATED FLEECE CAUSING THE FIBERS OF SAID FLEECE TO AGGREGATE INTO THE INTERCONNECTING GROOVES OF SAID PATTERNED SURFACE, AND REMOVING THE RESULTING APERTURED NON-WOVEN FABRIC FROM SAID PATTERNED SURFACE.
Claim 2
Independent Claim
85 words
AN APPARATUS FOR PREPARING AN APERTURED NON-WOVEN FABRIC WHICH COMPRISES A MOVING PATTERNED SURFACE OF LANDS AND INTERCONNECTED GROOVES, MEANS FOR CONVEYING A MOISTENED FLEECE OF TEXTILE-LENGTH FIBERS CONTINUOUSLY ACROSS SAID PATTERNED SURFACE AND IN REGISTRATION THEREWITH, MEANS COMPRISING A SOLID RESILIENT PADDLE FOR IMPARTING TO SAID MOVING FLEECE A SERIES OF REPEATED MECHANICAL VIBRATOR IMPACTS SUBSTANTIALLY NORMAL TO THE PLANE OF SAID FLEECE WHILE SAID FLEECE IS ON SAID MOVING PATTERNED SURFACE, AND MEANS FOR CONTINUOUSLY REMOVING THE RESULTING APERTURED FLEECE FROM SAID SURFACE.
