Abstract

The method involves forming uprights (3) with a ply core (4), so that the panels of particle board (5) with two facings are all held together by mouldings (2). The uprights are formed with the aid of a ply core retained between two exterior facings. The ply is cut to a length corresponding to that of the two, mortises and adhesion to the two facings is accomplished using quick setting glue. The whole assembly is positioned in a mould for form locking to hold the ply in place during drying, the moulding is completed with the placing of the mortices formed artificially by the empty space between the plies.

Description

DESCRIPTION
The present invention relates to a method for manufacturing interior distribution doors with flower bed panels.

The traditional technical state of manufacture of the doors consists in using solid woods for the realization of the panels, the uprights as well as the crosspieces. The disadvantages of this process are as follows - instability of the structure (twisting, shrinking of wood) - significant loss of wood during cutting, especially in precious woods - compulsory shaping of mortises in the uprights to allow the assembly of the sleepers - common aspect of the work - high cost price especially in precious woods; There is a second type of manufacturing; the amounts are then laminated glued in the width direction; they are then covered with a veneer. The panels are made of a particle board smashed in a machine for the bed and covered with press plating (said post-formed panel). The disadvantages of this embodiment are: - significant loss of wood during the flow - compulsory shaping of the mortises in the uprights to allow the assembly of the crosspieces - common aspect of the structure - high cost price
The invention consists, on the one hand, in the production of the uprights using a plywood core sandwiched between two exterior facings on an edge in the desired wood species. The plywood is cut to a corresponding length between two mortises; sizing on both sides of the plywood is carried out using a quick glue; the whole is positioned in a clamping mold with spacers at the level of the mortises (so that the plywood is kept in place during drying).

The upright is thus completely executed with the location of the mortises artificially constituted by the empty space between the plywoods).

The panels are them, made using standard market panels. A piece of wood called a molding is cut at 45 degrees in the corners and comes to mesh and stick around the panel, framing the latter. Peripheral machining is then carried out in order to be able to embed it in the uprights and crosspieces.

This manufacturing method has several advantages:
Technical advantage: stability of the structure simplicity of manufacture (exemption from mortises).

Economic advantage: it is possible to use market standard materials; moreover, this manufacture causes very little loss of material. Besides, all wood can be used, and finally, the manufacturing is fast.

Aesthetic advantage the manufacturing is not common; the relief around the panels gives a massive appearance to the whole. The final look mimics large frame doors; it is possible to mix wood species for design works.

The accompanying drawing shows in section a part of the interior door according to the invention.

With reference to this drawing, a part of the panel (1) is shown which is fixed to the upright (3) by means of a molding (2).
