Loop fastening material for fastening device and method of making same

Abstract

A laminated loop fastening material for a refastenable mechanical fastening system, the loop fastening material being capable of engaging a complementary hook fastening material. The loop fastening material is formed by a method comprising the steps of: providing a first lamina and a second lamina, the first lamina having pleats and being fibrous; providing a first roll and a second roll having mutually parallel axes and defining a nip therebetween, the first roll having a plurality of circumferential grooves and lands intermediate the grooves; passing the first lamina and the second lamina through the nip in face to face relation, whereby said first lamina faces the first roll; transversely registering the pleats of the first lamina with the grooves of the first roll; pressing the first roll and the second roll together about the plane generally perpendicular to and connecting the axes of the first roll and the second roll so that the first lamina and the second lamina contact each other at a position corresponding to the lands; and bonding the laminae together at the positions of contact.
