Definitions
- the invention relates to a light shield as defined by the claims.
- wood sheets according to the invention may be used more generally.
- logs are pieces of wood
- the parts with wood defects are then separated and the remaining parts are cut into thin sheets for the desired applications.
- Document is known CH 173.818 a method of manufacturing panels, by peeling. These panels are intended for the manufacture of plywood and are therefore of a thickness of about one centimeter.
- the invention relates first of all to a method of manufacturing natural wood sheets.
- a wooden ball 1 obtained from a tree trunk, having wood defects 2, surface or even heart.
- Any desired wood species may be used.
- defects it may be as well, for example, alterations in the veining and / or coloring of wood or marks such as those known to those skilled in the art under the name of lunure, rolling, gelation , prick, crawl, scab, groove or others.
- said sheets 3 are cut in said ball 1 while retaining said defects 2.
- the flawless portions 4 of the ball 1 will be separated from its defective parts 5. It is thus possible to obtain simultaneously, in the non-defective parts 4, wood sheets available for known applications such as the veneer, and in parts with defect 5, wood sheets available for new applications.
- said separation is carried out prior to the cutting of said sheets 3 in particular by separating said balls into three parts, a central and two extremals, the defects being generally located in the extremal portions of the balls, and then by cutting off said parts. extremals.
- said wood sheets are cut into the entire ball 1 stored and, optionally, the defect-free parts of the defective parts are separated.
- the cutting is carried out, for example, by slicing, that is to say, by cutting the ball 1 in planes parallel to the longitudinal axis of said ball 1, according to the arrow marked 6.
- the cutting is carried out by peeling, that is to say, by rotating the ball 1 about its longitudinal axis, according to the arrow marked 7.
- the cutting means used for said unwinding operation may optionally be oriented in an inclined manner with respect to the longitudinal axis of said balls. It will thus be possible to obtain wood sheets having a substantially conical shape and / or frustoconical, particularly advantageous for making lampshades.
- the cutting operations are performed, optionally, on dosse, that is to say on balls 1 previously cut radially, for example, in four parts.
- said ball 1 Before cutting, said ball 1 may be quenched.
- said wood sheets 3 are, in particular, laid flat, dried, trimmed and / or stacked. Their transport will thus be facilitated.
- the invention also relates to the natural wood sheets obtained according to the method described above. They may have a thickness, for example, from 5 to 10 tenths of a millimeter, in particular according to the species of wood, for example 5/10 th , 6/10 th or 7/10 th of millimeters.
- the invention also relates to a decorative article and / or utility consisting of such a wooden sheet and a sheet of support material attached to one of its faces. It may be, for example, a sheet of synthetic materials, such as, in particular, polyphane, fabrics or other materials. Said sheet is optionally transparent or translucent.
- the invention also relates to an application of such wood sheets and / or such articles to the manufacture of screens to light. It can thus be a shade. Said sheets of wood may also be associated with a glass support behind which it will be possible to have a light source so as to constitute a decorative lamp.
- said wood sheets and / or said articles are used, as is. We can use their flexibility and transparency.
