ABSTRACT:
A barbed tape includes a central supporting portion and a plurality of barb clusters disposed at spaced apart locations along the central supporting portion, each barb cluster having first and second pairs of oppositely extending substantially planar barbs disposed on opposite edges of the central supporting portion and connected thereto, the barbs having a cross section which is at least partially arcuate, whereby the barbs are substantially stiffened against bending. A process for forming a barbed tape having stiffened barbs includes the steps of providing a barbed tape having a central supporting portion and a plurality of barb clusters disposed at spaced apart locations along the central supporting portion, each barb cluster having first and second pairs of oppositely extending substantially planar barbs disposed on opposite edges of the said supporting portion and connected thereto, and roll forming the barb clusters so as to provide the barbs with a cross section which is at least partially arcuate, whereby the barbs are substantially stiffened against bending.
