| 摘要 | A wire is gear-crimped and gear-formed by passing it through a pair of horizontal gear wheels and subsequently through a pair of vertical gear wheels. The first pair of gear wheels crimps the wire to form high frequency undulations in the wire, which then is fed into the second pair of gear wheels to form low frequency undulations in a direction perpendicular to the low frequency undulations. Both pairs of gear wheels are driven by a common variable speed motor. | ||||||
| 权利要求 | 1. An apparatus for crimping and forming a wire comprising: a first pair of meshing gear wheels rotatably mounted in a first plane, each wheel of said pair having a first plurality of teeth adapted to crimp the wire to provide high frequency undulations thereon; a second pair of meshing gear wheels rotatably mounted in a second plane generally perpendicular to the first plane, each wheel of said second pair having a second plurality of teeth adapted to form the wire to provide low frequency undulations generally perpendicular to the high frequency undulations on the wire; and means for driving said first pair of gear wheels and said second pair of gear wheels. 2. The apparatus of claim 1 wherein there is a differential between the number of teeth on each wheel of said first pair of gear wheels and the number of teeth on each wheel of said second pair of gear wheels. 3. The apparatus of claim 2 wherein said first pair of gear wheels is provided with a first wire-feeding guiding means. 4. The apparatus of claim 3 wherein said second pair of gear wheels is provided with a second wire-feeding guide means. |
