Description

"PROCESS FOR MANUFACTURING THE DOORS FOR WINDOWS AND WRENCHES OR WOOD WASTE"

It addresses the present patent application for a new "PROCESS FOR MANUFACTURING OF WOODEN WRENCHES AND WRENCHES AND WINDOWS", especially a process for the manufacture of jambs for the reception of doors and windows by means of a reduced number of doors. stages using as main material battens and eucalyptus cutting residues properly arranged, glued, pressed and cut, resulting in an ecologically correct product.

It is well known to those skilled in the art that, in the application in question, it is the term used to designate the outline, generally wooden, of the wall opening to accommodate doors for the passage of persons within a building and windows which allow the ventilation and insolation of the indoor environments, and of course the external view to that environment.

Basically, the door is formed by the sheet responsible for sealing the wall when in the closed position; the knob / lock responsible for opening and or locking the leaf and finally the stop (or frame) usually of prismatic rectangular section. Already the window is usually covered by glass, mounted in wooden frame in turn framed in frame.

As already mentioned, wood remains the main raw material used in the manufacture of jambs for civil construction. Woods known as noble are great for this purpose because they do not require chemical treatment due to their natural characteristics, but are no longer used due to scarcity and fierce environmental control.

Less noble but less expensive woods from replanting areas such as eucalyptus require specific chemical treatments to compensate for the increasing fragility of this material over time. This fact, in addition to establishing additional costs to the product, also generates a form of aggression and pollution to the ecosystem.

In the present state of the art some patent documents are known which deal with alternative processes for obtaining stops, such as Pl 0600938-7 "Process of Manufacturing Doors and Plywood Fittings for Door Installation". Consisting of plywood production; manufacturing of stops; fabrication of the trimmings. The production of stops is composed by the cut in strips; adjustment in thickness in calibrator; recap bonding for unpainted parts; undercut and grooves executed in the semi-finished product, a undercut for backrest and a damper groove. As can be seen, this patent document uses plywood as its raw material.

MU 8102399-5 "Prefabricated Door Knocker". Consisting of two pillars, an upper beam and sill, all of which are prefabricated in reinforced concrete reinforced with metal structure supported by irons, being joined and fixed by a system of male and female fittings.

Aware of the state of the art, its shortcomings and drawbacks, the inventor, knowledgeable of the segment under consideration, after studies and research, created the PROCESS OF MANUFACTURING THE MOLDS FOR WINDOWS AND WRENCHES OR WOOD WASTE "in question, which uses as raw material eucalyptus wood from reforestation, as well as remnants of this material derived from the civil construction, furniture industry, logging procedures, etc. Basically, the flaps or battens are of various lengths, which are glued following an asymmetry between the ends to be pressed, flattened and cut to the predefined dimensions for making the stops.The battens to be glued should not be of the same piece so as not to copy the same defects while turning.

In short, the claimed process has the most important advantages:

> Use of reforestation wood;

> Appropriate disposal of waste or leftovers from various processes using eucalyptus (civil construction, sawmills, furniture industry, etc.);

> Resistance - does not bend and does not bend.

In the following, the innovative crosshead will be explained with reference to the accompanying drawings, in which they are illustrated by way of illustration and not limitation:

Fig. 1: Flowchart of the invented stop fabrication process;

Fig. 2: Sectional view showing the interleaved arrangement of the parts used in the invented stop fabrication process;

The "PROCESS FOR MANUFACTURING MOLDS FOR WINDOWS AND WRENCHES AND WINDOWS", object of this patent application, consists essentially of a process for obtaining door and window frames using eucalyptus wood / leftovers through a reduced number of steps.

More particularly, the claimed process begins in a first stage (E1) with the unfolding of the raw wood (log) aged at least fifteen years or with the choice of eucalyptus remains and flaps. In a second step (E2) the wood is braidedly stacked, separated by tabs at a distance that allows drying in the open with the help of sunlight for a period of at least four months. In a third step (E3) after outdoor drying, the wood is sent to a greenhouse for a period of at least thirty-five days, completing the drying cycle. In a fourth step (E4) the wood is unfolded in the form of battens, all in the same gauge. In a fifth step (E5) the battens are glued with wood glue, being arranged interchangeably to increase mechanical strength, generating plates preferably from one meter wide to three meters long. In a sixth step (E6) the battens are subjected to a press of about .100 psi for a period of at least four hours. In a seventh step the battens are removed from the press and remain at rest. In an eighth step (E8) the battens are unfolded in width 11 - 20 cm and thickness 3 - 3.8 cm to meet the fabrication of the stops. In the ninth step (E9) the stops are assembled and stored.
