Holshohlplatten for the production of doors, table tops, furniture parts Uedgl «

The unreasonable use of wood in the production of strong barrier panels (so-called table panels) has, for reasons of the need to save wood more than ever today, greatly encouraged the development of hollow panels in a wide variety of constructions inserted or rods in the frame, in the main direction parallel to the überfurnierten deck areas ₉ especially when polished or painted, usually the course of the deposits are visible in subsequent use can be to the longitudinal sides of the frame _a These Eonstruktion / EaTaen disadvantage because the type of inlay does not take sufficient account of the work of the glued-on barrier and face veneers or * barrier panels «

It has now been found that you can avoid these tile parts ₈ if you insert the chopsticks diagonally throughout the frame and use chopsticks made of strips of veneer with a thickness of about 4 mm .Height of the inserted sticks to fit each other about the stick width-zSn— »In order to be able to easily insert the veneer sticks into the frame timbers, the frame parts are provided with saw notches on their inner sides before assembly, which run at an angle of 45 °. This work step is advantageous can be carried out by means of an inclined angle of 45 ° the saw motor via a package of wooden frames ^ wherein the saw motor automatically drawn with a spindle on the opposite on a trolley Räamenhölzerpaket and the carriage tandsbreite after each cut to a respective para transported _e Ss but can also the 'Sägsmotcr sum.

In the hollow panels produced in this way, all the veneers glued on are supported or held at short intervals in the direction of their fiber path. The diagonally below the shut-off and glued veneers deck or _e Sperrholideckplatten extending

Compared to the known constructions, this has the advantage that the shrinkage in width and the expansion in width, acting perpendicularly within the plane of the panel to the direction of the grain, does not result in the disadvantages mentioned above »

The accompanying drawings show as an embodiment a plywood hollow door made according to the invention with both sides glued-on plywood with a thickness of 4 m as well as "a cupboard, which on both sides only has a plywood veneer along with a veneer made of precious wood is marked «Ss point

The frame is composed of solid or glued frame timbers I, 2j3s4, which are provided with saw notches 5 at an angle of about 45 ° on the inner side before they are assembled attached so that the approx. 4 mm thick veneer strips 6 can be inserted into the slots of the assembled frame _e

For the production of hollow doors, after inserting the veneer strips 6 at the level of the door locks to be attached later, A massive amount of wooden blocks 7 are inserted between the sticks on both sides Middle layers 8 are glued on the desired outer layers in the usual way as required, e.g. the barrier veneers according to F & g «1 and 2 9 with fine veneer layer IO and according to Fig. 3 and 4 the plywood sheets He

The hollow plates produced according to the invention can be with excellent results for the production of doors, furniture _s tabletops, etc. use. They enable considerable wood savings while avoiding the disadvantages associated with the known hollow slabs.
