Abstract

A method, and a machine for performing the method, for treating wood panels to develop a relief therein, and including subsequent staining, comprising brushing a panel to develop a relief, and then flooding the panel with liquid stain, and after drying, again brushing the panel surface, resulting in a contrasting and attractive panel surface.

Claims

1. A method for treating a surface of a wood panel in which the panel surface is treated with brushes to develop a relief and subsequently is stained comprising:

brushing the panel surface by means of first brush means rotating about a generally horizontal axis extending substantially transverse to the longitudinal extension of the panel to develop a relief in the longitudinal direction of the panel surface, then brushing the panel surface by second brush means rotating about an axis extending in a direction generally perpendicular to the direction of extension of the first mentioned axis, to apply relief producing brushing generally transverse of said longitudinal extension of the panel, then flooding the panel surface with liquid stain and brushing wax into the panel surface whereby said panel surface is smoothed.

2. The method according to claim 1, wherein prior to said staining, the wood panel is passed first beneath cylindrical brushes comprising said first brush means rotating about horizontal axes oriented generally perpendicular to the longitudinal extension of the panel, and is then passed beneath a plurality of cylindrical brushes comprising said second brush means rotating about horizontal axes which extend in the longitudinal direction of the panel and are offset parallel to one another, and is then passed beneath cup brushes rotating about vertical axes, said cup brushes likewise comprising said second brush means for applying further brushing generally transverse of said longitudinal extension of the panel, and wherein said brushing of said wax into the panel surface occurs in said longitudinal direction of the panel surface.

3. A method according to claim 1 including applying said wax to said surface simultaneously with said stain, and wherein said stain contains said wax in finely dispersed form.

4. A method in accordance with claim 1 wherein said panel is adapted to be moved face up beneath said brush means, including rotating said first brush means about horizontal axes extending generally transverse of the path of movement of the panel, and then rotating said second brush means about vertical axes extending generally transverse of said path.

5. A method in accordance with claim 4 wherein said second brush means includes a plurality of cylindrical brushes rotatable about horizontal axes which extend parallel in the longitudinal direction of the panel surface and including offsetting the axes of rotation of the last mentioned brushes with respect to the lengthwise center of the path of movement of the panel.

8. A method according to claim 5, in which the sense of rotation of the cylindrical brushes, which are offset to the center line of the panel, is selected such that the brush surfaces beneath the axes of rotation move over the panel from the edge of the panel towards the center thereof.

9. A method according to claim 1 characterized in that after having passed the panel surface beneath said first brush means, the panel surface is passed beneath steel cup brushes rotatable about generally vertical axes extending transverse to the wood panel plane, each said cup brush having a diameter of approximately 1.5 times the panel width and comprising said second brush means.

6. A method for treating surfaces of wood panels, in which the panel surface is treated with brushes to develop a relief and subsequently is stained, comprising steps of first passing the wood panel beneath metal wire cylindrical brushes rotating about horizontal axes extending generally transversely to the longitudinal extension of the panel to develop a relief in the longitudinal direction of the panel surface, and next beneath a plurality of metal cylindrical brushes rotating about horizontal axes extending in the same general direction and generally parallel to the longitudinal extension of the panel, the last mentioned axes being offset symmetrically to the vertical longitudinal center plane of the panel and extending in a direction generally perpendicular to the direction of extension of the first mentioned axes of apply relief producing brushing generally transverse to said longitudinal extension of the panel, and then passing the panel through a stain flooding device for staining the panel surface ad applying wax in finely dispersed form to the panel surface and then passing said panel surface underneath polishing brush means rotatable about generally horizontal axes extending generally transverse to the longitudinal extension of the panel, whereby said panel surface is smoothed.

7. A method in accordance with claim 6, in which the wood panel, after having been passed underneath the first and second mentioned cylindrical brushes, is passed underneath steel cup brushes rotatable about generally vertical axes extending transverse to the wood panel plane, with the last mentioned vertical axes extending generally perpendicular to the direction of extension of the first mentioned axes for applying a further relief producing brushing generally transverse of said longitudinal extension of the panel and prior to the staining and waxing of the panel surface.
