| 摘要 |
Portable electric machine (10) for stripping cork bark (92) with a sawtoothed blade (35), a device with a fork-shaped foot (50) that embraces the saw (35) that makes contact with the bark (92), a high-conduction needle (85) to be pressed into the cambium (91) and a microprocessor (61) that, in accordance with the variations in electric resistance between the tip of the saw (35), inserted in the insulating cork (92), and the electrically conducting cambium (91), determines movement of the foot (50) so that its distance from the tip of the saw, from one position to the next and moment by moment, is substantially equal to the thickness of the cork bark (92) thus permitting maximum penetration of the saw (35) while ensuring integrity of the cambium (91).
