Abstract
A smoothing machine for wood panels, particularly wood panels having contoured surfaces with parts in relief, includes a substantially horizontal conveyor belt, a support structure overlying the belt, and a plurality of smoothing units carried by the structure. Each smoothing unit comprises a support frame and an abrasive roller rotatably supported by the frame and driven by a motor mounted on the frame, the rollers facing the belt and having coplanar horizontal axes of rotation. In the machine, each of the frames is pivoted about a vertical pivot axis on a motor-driven rotor rotatably supported about a vertical axis of rotation by the support structure, and the frames are releasably fixed to the rotor. The machine enables multi-directional smoothing whereby it is possible to smooth even very irregular panels.
Claims6
A smoothing machine for wood panels, particularly but not exclusively wood panels having contoured surfaces with parts in relief, said smoothing machine comprising:
- a substantially horizontal conveyor belt;
- a support structure overlying said belt;
- a plurality of smoothing units carried by said structure, each smoothing unit comprising a support frame, an abrasive roller rotatably supported by said frame, and a roller drive motor mounted on said frame, the rollers facing the belt and having coplanar horizontal axes of rotation;
- a rotor supported by said support structure about a vertical axis of rotation;
- means for releasably fixing said frames of said smoothing units to said rotor, wherein each of said frames are pivoted on said rotor about a vertical axis such that each of said rollers can act along a different, independently adjustable direction from one another;
- and
- a motor for driving said rotor, said rotor rotating along sai vertical axis while each of said rollers of said smoothing units rotate along said coplanar horizontal axis.
