ABSTRACT:
An apparatus and process is provided for forming a helical barbed tape. The process first involves supplying rolled steel which is passed to an apparatus for blanking barbs and cutting the steel into strips. The strips are mounted on individual cassettes. The tape subsequently is fed from a cassette to a barb sensor and barb setter. The barb setter moves with the tape to effect the required offset in response to the sensed presence of a barb cluster. The tape then advances to a roll former which exerts a controlled differential pressure on opposed sides of the tape to create a uniform circular coil. The tape will have an unequal thickness across its width with the differential thickness being substantially uniform along the length of the tape.
