SPINNED-IN ARMORED BARBED TAPE "KAYMAN" Russian patent published in 2011 - IPC B21F25/00 

FIELD: process engineering.

SUBSTANCE: invention relates to production of spinned-in armored barbed tape to be used for security barriers. Proposed tape is produced from metal strip and contains central part with opposed pairs of primary injury elements arranged in one plane along tape central part with equal spacing. Every injury element in a pair consists on the base and opposed teeth made on lateral sides of said element. Points of each tooth are made up of angles formed between outer and inner sides of injury element. Additional injury elements with teeth directed toward those of primary injury elements are arranged between lateral sides of the latter. Central part of the tape is reinforced by flexible element in the form of wire fastened and fixed by spinned-in edges of central section. Primary and additional injury elements are arranged at different angles relative to each other to very from 0° to 90° and furnished with one or several tenons arranged perpendicular to the tape lengthwise axis.

EFFECT: better barrier properties, stable flexible and properties and shape.
