| 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. | ||||||

| A metal tape barrier has a generally constant edgewise arcuate curvature and a channel providing a lengthwise bight having a reinforcing wire therein. The tape wraps from about 200.degree. to about 220.degree. of the periphery of the wire, just sufficient to hold the wire in place. Continuous flange regions of the tape extend outwardly of the channel and cooperate with the channel and the reinforcing wire to impart strength to the barrier so that it is self-supporting and is resistant to being collapsed. The tape has barbs formed outwardly of the flange regions and reduced width regions of the flange regions at the roots of the barbs enhance the penetration capabilities of the barbs. | ||||||

| A machine having blanking, barb forming and bending stations is provided for making a coil of metal tape from a substantially planar linear strip of metal stock wherein such strip is fed in sequence to the stations in a single pass through the machine to respectively edge notch the strip into barbs, upset the barbs into inclined relation to the plane of the strip and then edge bend the strip in the plane of the strip to form it into identically angularly displaced adjoining linear segments of equal length to make a generally annular coil of barbed metal tape.The method of this invention features forming spaced openings along a longitudinal axis of a substantially planar linear strip of metal stock, positioning the strip by means of its openings and edge bending the strip in the plane of the strip adjacent its openings to form the strip into a coil having identical angularly displaced adjoining linear segments. | ||||||
| 354 | Process and apparatus for producing a barbed spiral | US50813374 | 1974-09-23 | US3916958A | 1975-11-04 | UHL SIEGFRIED |
| A process and apparatus for producing a barbed spiral from a flat metallic barbed strip having a series of barbs and a supporting wire wherein the wire and metallic strip are combined in envelope rollers so that the wire is embedded into a flat metallic strip. At the output of the envelope rollers is a reel for winding the wire supported strip in convolutions so that every other barb of adjacent convolutions can be connected together to form a spiral fence when the assembly is opened in a longitudinal direction. The invention includes a plurality of circumferentially spaced-apart clamping devices which are mounted on a rotary table which rotates synchronously with respect to the reel. There is provided a means for lowering the reel corresponding to the rise of the winding with respect to the rotary table and the output of the envelope rollers. Fingers are also provided for compressing the convolutions on the reel as they are being gathered.

| 356 | Reinforcing rod machine | US3690349D | 1971-03-15 | US3690349A | 1972-09-12 | DONCHE-GAY PIERRE |
| A machine for the manufacture of reinforcing rod having spaced apart flattened portions wound with turns of smaller diameter rod has a pair of constantly turning forming rollers which feed the rod between them and form the spaced apart flattened portions and the machine has a reciprocating winding head which winds turns about the flattened portions of the rod while advancing with the rod. A drive for the forming rollers rotates cams which oscillate a yoke which reciprocates the winding head. The drive for the forming rollers also, through sprockets and a chain, rotates the winding head arbor. The chain driving the winding head arbor incorporates a spring chain tightener to compensate for the oscillation of the winding head. The reciprocation of the winding head causes a sector gear on the winding head engaging a fixed rack to drive rod metering rollers which extend smaller diameter rods to be wound about the flattened portions of the reinforcing rod.

| In the mounting of barbed wire as on fence posts it frequently happens that the wire is broken in the tensioning. This tensioning is generally done with a mechanical device. The difficulty is due to the fact that the wire has a very low extensibility prior to breaking. Methods of shaping the wire during manufacture are disclosed; by such shaping the extensibility is increased and the likelihood of breaking during the mounting process is decreased or eliminated.
