| 摘要 | 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. | ||||||
| 权利要求 | 2. Strip according to claim 1, characterized in that supplementary cuts of fishhook shape are made near to the third cut of each set of lateral cuts for limiting two hooks opposite to each other which are made to coincide with one another when the strip is extended, so that said hooks keep said strip in an opened-out state for which the zones limited by the various cuts project in different planes. 3. Strip according to claim 2, characterized in that the hooks are made symmetrically in relation to the longitudinal axis of the strip and in that they are subjected to twisting so that they fit into each other. 4. Strip according to claim 2, characterized in that the hooks are made to face each other but in opposite directions. 5. Strip according to claim 1, characterized in that beginnings of cuts are made in the various parts limited by the cuts and in that the parts contiguous to said beginnings of cuts are bent like a jagged-set tooth saw. 6. Strip according to claim 1, characterized in that the strip is made of resilient metal sheeting. |
