Abstract: The single part (1) of the door, is hollowed by fine milling and with side moldings of solid wood flush with the covering panels (4) and (5), the ends of parts (3.1) of the premolding (3) being arranged at an angle of 45°.

Description: OBJECT OF THE INVENTION The invention herein defended consists of a manufacturing procedure of agglomerated particle doors and thus manufactured doors, of the type which are carried out by means of pantographs and are presented with counterboring and covering moldings. This invention is characterised by a specific manner of manufacturing the door, mill hollowed and with side moldings, and with 45° angled parts with solid wood pieces arranged flush with the panel covering BACKGROUND OF THE INVENTION The doors produced by pantograph are provided with rounded corner hollowed parts, because the continuous machining passing operation prevents the formation of angles at said corners. Thus, the molding squares are finished off rounded, so that this construction is easily identified. On the other hand, when an angled square corner finish is desired, the manufacturing procedure is that of the consecutive assembly of preformed parts, in such a manner, that the construction is started by the lower crossbeam, subsequently placing and attaching the side columns, arranging the internal part or parts, the new intermediate crossbeams, the agglomerated boards or the glass panes, the veneered sheets, the enamelled glass etc. and finally, the upper crossbeam which closes the assembly. This procedure, though correct, is highly expensive in relation to time and manpower, apart from requiring greater specialisation of the finishes. US-A-4 756 350 discloses a manufacturing procedure comprising all of the features of the preamble of claim 1. When solid wooden rails and tails which are mitred at their ends to form a right-angled connections, are machined around their edges by a router it is necessary that the router using a rotating bit extends beyond the position of the corner connection, a distance equal to the radius of the bit, being finished by being covered by moulding strips mitred at their ends to form right-angled corner connections, as this way there is no need to round off the ends of the moulding strips to allow them to extend completely into a corner of a panel opening. PROCEDURE OF THE INVENTION The invention which is the object of the present Specification refers to a manufacturing procedure for agglomerated particle doors, of the type which are carried out by means of pantographs, milling the internal perimeters of the hollows, and which are presented with recess finish and with covering moldings, as well as with a conventional solid wood framing, joined by means of male-female spigots to the boards. This invention is characterised by a specific door construction procedure, also made from one single piece, though with angled finish of the corner squares, based on a milled hollowed door arrangement and with a premolding applied at the sides of said cutting. This milling produces a very slightly rounded finish, side projecting at both ends near the vertex in the manner of very small circular area. The premolding, also of solid wood, is applied by lateral bonding, the individual premolding parts being joined at an angle of 45° and covered by the covering panel or panels, generally boards derived from wood and of the various conventional covering panels, including shielding plates, the latter either on one side of the door or on both sides. DESCRIPTION OF THE DRAWINGS In order to complement the description which is being carried out, and with the object of facilitating a better and easier understanding of the characteristics of the invention, the present Specification is enclosed, forming integral part of the same, with a set of drawings in which, with illustrative and non limitative character, the following has been represented: Figure 1 shows a front elevational view of the door with agglomerated particle boards. Figure 2 shows a partial cross section of said door. Figure 3 shows a partial cross section of said door, in order to observe the finish of the same. Figure 4 is a constructive variation for the inclusion of a transparent sheeting, for example of glass. PREFERRED EMBODIMENT OF THE INVENTION In view of the above description, the present invention refers to a manufacturing procedure for agglomerated particle door and doors thus constructed. Firstly, from a single door particle sheet (1) are cut hollows which form the internal portion of an outer frame for the leaf. The frame is surrounded with solid wooden rails and stiles. The hollows are machined by a routing using a bit. The rotating bit extends beyond the external apex of the moulding strip corner connection a distance equal to the radius of the bit. So, two small semicircular recesses (1.2) are formed at each of the opening. The surfaces of the machined edges are covered with moulding strips (3), which are mitred at their ends to form right angle connections. Continuing with the process the solid wooden rails and stiles (2) are side bonded intermediate two high pressure stratification panels and two double layers of solid wood panels (5) so that the path which the rotating bit extends beyond the external apex of the moulding strip is covered by the edges of the panels (4) and (5). Afterwards the edges (3.3) of the moulding strips (3) are finely milled, so getting an edge (3.4) of the moulding mortise coplanar with the edges (4.1) and (5.1) of said panels (4) and (5). Alternatively it is possible to provide a metallic shielding plate between the high pressure stratification panels (4) and another one between the double layer solid wood panels (5).

Claims: Manufacturing procedure for agglomerated particle door, wherein straight-edged panel hollows are cut from a single sheet (1) of particle board to form the internal portion of an outer frame for the leaf, this frame being completed by surrounding it with solid wooden rails and stiles (2), and said solid wooden rails and stiles are machined around their edges by a router using a rotating bit and the surfaces of the machined edges being subsequently finished by their being covered with moulding strips (3), these strips being mitred at their ends to form right angle connections, characterized in that when machining each edge of a panel opening the path of the rotating bit of the router extends beyond the position in which the external apex of the moulding strip corner connection will lie by a distance equal to the radius of the bit, thus forming two small semi-circular recesses (1.2) at each corner of an opening. Manufacturing procedure for agglomerated particle door, according to claim 1, characterized in that the solid wooden rails and stiles (2) are side bonded, intermediate to two high pressure stratification panels (4) and two double layer solid wood panels (5) so that the path of the rotating bit of the router which extends beyond the position in which the external apex of the moulding strip corner connection will lie is covered by the edges of the panels (4) and (5). Manufacturing procedure for agglomerated particle door, according to claim 2, characterized in that afterwards the edge (3.3) of the moulding strips are fine milled, thus getting the edge (3.4) of the moulding mortise coplanar with the edges (4.1) and (5.1) of the said panels (4,5). Manufacturing procedure for agglomerated particle door, according to claim 1, characterized in that between one of the high pressure stratification panels (4) and one of the double layer solid wood panels (5) is added a metallic shielding plate. Agglomerated door particle obtained by the manufacturing procedure claimed in any of claims 1 to 4 wherein straight-edged panel openings have been cut from a single sheet of particle board having been completed by surrounding it with solid wooden rails and stiles, where in said wooden rails and stiles has been machined around its edges by a router which has extended beyond the position of the apex a distance equal to the radius of the bit, being subsequently finished by their being covered with moulding strips which are mitred at their ends to form right angle connections, covering such distance extended.
