Surface levelling device and method |
摘要 |
A surface levelling device for levelling surfaces such as a wooden floor, the device including a rotatable cutting head (130) which is mounted in a movable framework (4) by means of independently controlled screw devices (84, 86). The screw devices are controlled by control circuits (130, 132) which are responsive to a sweeping laser beam (222) which rotates in a reference plane. The control circuits maintain the cutting head (130) parallel to the reference plane and at a predetermined distance therefrom regardless of movements of the framework (4) over the floor.
