Method of making a barrier material

摘要

A method and apparatus for making a barrier material. The method includes forming barbed tape at a barbed tape forming means (12) and feeding the barbed tape to bending means (14). At the bending means (14), the barbed tape is provided with a plurality of longitudinally spaced apart kinks and the portions of the barbed tape between the kinks is bowed outwardly. The kinked barbed tape is then interlaced with a previously formed kinked barrier element at an interlacing station (16) to manufacture the barrier material.
