Definitions

  • the present invention relates to an installation for processing the files for their recovery.
  • dosing The piece of wood which is detached when washing a log at the start of sawing is called "dosing".
  • the backs have a flat face erected with a saw and the rest of the surface, called the back, is a segment of the log.
  • the backings obviously have an irregular shape and dimensions which make them unusable, except for making charcoal or, after costly reprocessing, small strips.
  • the present invention proposes to enhance the backing by making, economically, from the latter, new products of standardized shape and dimensions.
  • This object is achieved by the invention in the sense that it provides a treatment installation which comprises, in a manner known per se, conveyor means adapted to receive, route and evacuate the slabs before, during and after treatment. , pressing means applying the flat face of the backing against the conveyor means, and cutting means capable of acting on the back of the backing.
  • the installation is characterized in that it comprises first cutting means located on either side of the conveyor means, in the vicinity of their receiving end, which first cutting means are adapted to pre-align the slabs to create surfaces reference, and second cutting means mounted on the internal face of a hollow rotor through which the conveyor passes, downstream of the first cutting means, seen in the conveying direction, said second cutting means being adapted to give a surface standard convex on the back of the pre-aligned backs.
  • the first cutting means can consist of strawberries.
  • the second cutting means can also be constituted by cutters or by fixed knives depending on the hardness of the treated wood.
  • the pressing means are advantageously made up, in the amount of the rotor, seen in the direction of conveying the slabs, of cylinders with notched periphery which act on the slabs before treatment and, downstream of the rotor, of cylinders with concave periphery which act on the slabs after treatment.
  • the slices of the treated slabs can be flat as mentioned above, they can also include male and / or female reliefs allowing them to be nested side by side.
  • the installation comprises, downstream of the rotor, seen in the direction of conveying the slabs, appropriate means of tipping.
  • the installation includes a frame 1 supporting an endless conveyor 2 driven, by means of a belt 3, by a motor 4.
  • the conveyor 2 has one end 5 and a discharge end 6, so that the slabs are conveyed in the direction indicated by the arrows F.
  • the frame 1 also supports hydraulic or pneumatic means 7 adapted to apply notched pressure cylinders 8a and 8b on the slabs resting on the conveyor 2.
  • FIG. 2 The structure of the rotor emerges more clearly from FIG. 2 where it can be seen that its internal face is furnished with milling cutters 12 or fixed knives 13, the choice between milling cutters and fixed knives being dictated by the hardness of the treated wood.
  • a pair of pressing cylinders 14a and 14b is provided downstream of the rotor 9, the concave periphery of which corresponds, in curvature, to the convexity imparted to the backings by the cutting members of the rotor 9.
  • the dosage is as shown in FIG. 2a, that is to say that it has a flat surface 17 and an irregularly roughly convex back 18.
  • the first step is to create reference surfaces such as A, B, C, D on each side of the backing to ensure proper guidance and centering of the piece of wood in the rotor.
  • the cutting members 12 or 13 of the rotor then create the standardized convex surface 20 of the finished product as shown in FIG. 2b.
  • the planing means 15 form in the reference surfaces A, B, C, D, respectively, a tongue 21 and a groove 22.
  • the finished product is likely to be used as interior paneling, as exterior trim for garden sheds (its rounded appearance pronounced of that of logs), as cladding of construction sites for poor quality wood (for example when it is of the sapwood of the oak), the undulating configuration of the resulting walls discouraging the display.
  • the product according to the invention can also be used for the manufacture of packaging.
