Description

Jezeli zewnetrzne powierzchnie plyty ma¬ ja byc wykonane z jakiegos specjalnego drzewa, to wtedy pokrywa sie boczne kra¬ wedzie fornierów c, c i wolne powierzch¬ nie listwy d zewnetrzna listwa e, wykona¬ na z pozadanego drzewa. Oprócz tego po¬ krywa sie czesto zewnetrzne powierzchnie fornierów c oraz szczeliny pomiedzy for¬ nierami c i listwa e zewnetrznemi fornie¬ rami f, f z pozadanego gatunku drzewa.[Kierunkowi wlókien, tych fornierów ze¬ wnetrznych najkorzystniej jest nadac kie¬ runek prostopadly do kierunku wlókien fornierów wewnetrznych.Zamiast dwóch warstw fornierów moz¬ na oczywiscie zastosowac takze wieksza ilosc fornierów.Plyta, wykonana w mysl niniejszego wynalazku, moze miec dowolna grubosc; w tym celu mozna zastosowac wieksza ilosc warstw wewnetrznych albo dac grubsze deski. — 2 —Plyta, wykonana w opisany sposób, jest tansza od plyt, wykonanych znaneml dotad sposobami, poniewaz listwy szkiele¬ tu sa stosunkowo waskie, a zewnetrzne po¬ wierzchnie plyt moga byc pokryte tylko jednym lub dwoma cienkiemi fornierami.Plyta taka jest mniej wrazliwa na waha¬ nie temperatury i zmiany atmosferyczne, niz znane plyty tego rodzaju. Omawiana plyta nadaje sie szczególnie do wyrobu drzwi. PLIf the outer surfaces of the board are to be made of some special wood, then the side edges of the veneers c, c and the free surfaces of the board d are covered with the outer board e made of the desired wood. In addition, often the outer surfaces of the veneers c and the gaps between the formers and the batten e and the outer veneers f, f of the desired tree species are often covered. In place of the two layers of veneers, it is of course also possible to use a greater number of veneers. A board made in accordance with the present invention may be of any thickness; for this purpose, more inner layers can be used or thicker boards can be used. - 2 - A board made as described is cheaper than boards made using methods known so far, because the strips of the carcass are relatively narrow, and the outer surfaces of the boards can be covered with only one or two thin veneers. Such a board is less sensitive temperature fluctuations and atmospheric changes than known panels of this type. The plate in question is particularly suitable for making doors. PL

Claims

Patent claims. 1. A board made of wooden planks, particularly suitable for the manufacture of doors, and consisting of a skeleton made up of at least three layers of slats, arranged crosswise with respect to each other, characterized by the fact that both outer layers of the skeleton are covered with veneers ( c), glued individually or twice (c, f), are composed of relatively narrow strips fb), placed loosely next to each other without sticking them together, but stuck from the inside to the middle of the strips (a), arranged in the usual manner next to each other at certain intervals.

2. Wooden board according to claim 1, characterized by the fact that it is provided with an edge blade (d) with a thickness equal to the thickness of the entire skeleton, while the edge blade (d) is provided with an internal groove (d ') f which is inserted between the battens (b, b) both outer skeleton layers.

3. Wooden board according to claims 1, characterized in that it is provided with a blade, which serves to cover the edge of the board, perpendicular to the length of the battens (a) of the internal skeleton layer, and whose thickness is equal to the thickness of the battens (a), with the latter being inserted between the battens ( b, b) the outer layers, perpendicular to the length of the laths (a) of the middle layer.
