| 181 | Method of manufacturing barbed tape | US434007 | 1989-11-09 | US5109583A | 1992-05-05 | Michael V. Pavlov |
| A barbed tape with a longitudinally extending strengthening groove is formed by pushing a strip of barbed tape to and through forming rolls which cooperate with the tape and a wire mandrel. The wire mandrel includes a continuous loop of wire rope which is guided to and through the forming rolls with the strip of barbed tape to form the longitudinal strengthening groove in the tape. The wire mandrel remains in cooperation with the tape as the grooved tape and wire mandrel move through a radial bender which bends the tape into a helical coil. The tape is provided in reel form and is fed to a blanking press to have barbs formed thereon prior to being fed to the roll former. A take up device receives the coiled tape as it exits the radial bender. | ||||||

| 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 method and apparatus for providing barbed strap coils without a core by means of a ring coiling device (50) that has no winder provides a single clamping device (96), whereby the coiling is interrupted for the placement of a clamp. A guide device (11B) is arranged in front of the clamping device (6) by means of which two strap sections separated by the one loop can be pushed toward the clamping device (96) by means of a strap feeding device (38). The two coils are guided outside the interruption in the coiling synchronously and in like phase through the location where the clamps are applied, by a synchronization device (60) in the clamping device (96) which engages slip-free in the two strap sections by means of a member (62). A counter (80) that counts the member movements between two successive clamping steps is coupled with member (162). | ||||||

| 185 | Barbed tape with reinforced barbs | US927833 | 1986-11-06 | US4718641A | 1988-01-12 | Michael R. Mainiero |
| A helical barbed tape is provided with reinforced barbs. The tape includes a plurality of barb clusters at spaced locations along a central supporting portion. Each barb cluster includes a pair of oppositely directed barbs with the respective pairs being disposed on opposite sides of the central supporting portion. The reinforcement is defined by a portion of the respective barbs which extends out of the initial plane of the barbs. In one embodiment, the reinforcement defines an elongated reinforcing flange. In other embodiments, the reinforcement defines an embossment extending out of the plane of the barbs. | ||||||

| A barbed wire comprises a metal strip having a longitudinally extending reinforcing rib portion and at least one plate portion extending laterally outwardly from the rib portion along its length. The plate portion has a series of triangular contiguous pointed projection portions with longitudinally extending bases and with an apex point extending outwardly from the bases offset longitudinally from the point of intersection of adjacent bases of the respective triangular projection portions. The rib portion may be reinforced by a thickened formation and a plurality of plates may extend, for example, radially outwardly from the reinforcing rib portion. | ||||||

| Strip for obtaining a barbed member in which are made lateral cuts each consisting of an oblique first cut emerging on the lateral edge, a second cut, parallel to said lateral edge and communicating with the end of said first cut, and a third cut extending from the free end of this second cut to the vicinity of the longitudinal axis of the strip, said lateral cuts being combined with median cuts extending between two successive sets of lateral cuts, said median cuts each having a longitudinal portion from whose ends there extend two portions of cuts limiting appreciably triangular parts.
