Headrest frame and method |
| 摘要 |
A device and method for forming notches in tubes or other parts includes a roller that travels along a non-linear path. The roller may include a component of motion away from the part to reduce bulging or other deformations in an outer surface of the part that could otherwise result from a straight roller path. |
