ABSTRACT:
Self-gripping devices are disclosed and include a base having one or more integral trains of generally upright gripping elements which are adapted to penetrate and become lodged in a receiving material and especially receiving materials containing fibrils to form a self-gripping connection. The gripping elements in each train have a common origin in a continuous rib integral with the base. Self-gripping devices having a plurality of gripping elements capable of unique self-gripping action are also disclosed.
A method is disclosed wherein a structure is formed with integral ribs which are cut to form spaced apart gripping elements.
