Description of Related Arts

Production processes and parts to finish walls, especially to cover wall joints with lining and with the floor are already known and have been widely used for a long time.

Regarding the production processes of these finish profiles, they used to be manufactured in plaster, presenting high frailty and great rigidity as main hindrances that made them difficult to store, transport and apply. Afterwards and in order to overcome those inconveniences, plastic manufactured parts obtained through foamable polystyrene extrusion were developed. Meanwhile, due to the manufacturing process and employed raw materials, these parts still present the following limitations: significant frailty and rigidity, whereby damages during storage, transportation and application may occur; the polystyrene foam presents open cells that are capable of absorbing water, thus generating variations in profile dimensions that is unwanted for this finality; they present low resistance to tightening, showing plastic deformation easily in case they are impacted; - they do not resist the use of .solvents contained in certain types of paint, restricting thus paint work; they present limited elasticity and flexibility, making the installation on regular walls that are common to civil works and the covering of curved parts such as circular columns difficult; - they are produced in limited lengths, generally between 2 and 3 meters, causing difficulties when installed for they demand diverse emendations to complete

the gap of the walls, which apart from requiring specialized workmanship, may result in aesthetic damage.

Similarly, the plaster part presented a series of inconveniences: high frailty, making it difficult to store, transport and apply for it can break very easily; great rigidity, which makes the cut and application of the profile difficult, mainly when the edge formed by the joint of the wall with the lining or floor presents undulations because the plaster profile does not accompany those masonry irregularities, therefore demanding subsequent finishing works with a mass of plaster powder or similar that demands effort and expending a considerable amount of workmanship.

Further on, plastic profiles obtained from foamable polyurethane (PU) extrusion were also developed. These finish profiles present a PU molded interior and an external covering film from another polymeric material which provides the finish to it. Such covering film admits painting with solvent based paints. Meanwhile, this manufacturing process resulted in a PU profile with the following limitations: as time goes by, the PU foam, degrades and is affected by sun rays and in case it is white, it ends up turning yellow, thus demanding the presence of a finish film; - it presents significant frailty and rigidity, whereby damages during storage, transportation and application may occur; they are produced in limited lengths, between 2 and 3 meters, demanding diverse emendations so as to complete the gap of the walls, which requires specialized workmanship and may result in aesthetic damage; - it can absorb water, generating variations in the dimensions of the profile; it presents low resistance to tightening, showing plastic deformation easily; it presents limited elasticity and flexibility, making its installation on regular walls or circular columns difficult.

Another technical problem identified in the finish profiles is regarding their fixation. Currently, it is known that familiar finish profiles require the employment of glues and adhesives, as well as great ability and experience from the installer. Furthermore, if the installer is not cautious, he may apply an excessive amount of glue that will drip

and dirty the wall, and on the other hand, the lack of glue will produce the profile to become loose. Therefore, known application techniques for finish profiles are intensive when it comes down to workmanship, requiring costly glues and adhesives and being subjected to the ability of the professional. Another problem found in the state of the technique is the fact that the stretches are not continuous, wherein its emendations are perceptible for the naked eye, having been sanded at times so as to disguise the emendation. Aim of the Invention

It is destined to solving the aforementioned problems and the aim of this invention is a finish profile for walls, half walls and linings composed by an EVA (Ethylene Vinyl Acetate) or polyethylene base, or the mixture of both of them, with own optional fixation means or not, and its manufacture and fixation processes.

The process represented in the flowchart of figure 1 for the production of finish parts for walls and linings encompasses the following stages: a) manufacture of EVA (Ethylene Vinyl Acetate) based foamable material or polyethylene plates, or the mixture of both, which represents great flexibility and elasticity, resulting thus in very malleable parts; b) section of a plate in long strips and with a length that corresponds to the profile that is to be manufactured; c) union of the ends of the strips forming a continuous strip of foamable material; d) preliminary coiling of a strip forming a reel; e) obtainment of a definitive transversal section of the profile through abrasion of the continuous strip; f) final coil of the finished profile in a reel.

Preferably, the abrasion stage can be executed in machines outfitted with abrasive stones (grindstones) or steel discs which present a peripheral surface with the form corresponding to the reverse image of the transversal section to be produced.

Preferably, stage (c) can occur through gluing or welding of the strip extremities.

The stage (e) can be preferably executed in machines outfitted with abrasive stones (grindstones) or steel discs which present a peripheral surface with the form corresponding to the reverse image of the transversal section to be produced. Stage (e) can be executed in one single stroke where the grindstones act simultaneously on both sides of the profile, i.e. on the visible side of the profile and on the side that will be in touch with the wall, lining or floor. This stage can be alternatively executed in two strokes: one for each side of the profile. The stage can be even and alternatively executed in diverse strokes in order to obtain the definitive profile form gradually. The design printed on the final product can also be obtained through thermal shock by means of printing (heating of the product and stamping it with refrigerated matrix). The production process of the profile for the finish of walls and lining as proposed by this invention results in the following advantages regarding all other manufacturing processes for profiles with that finality:, - it is a continuous and highly productive process; it results in a continuous profile which is coiled into a reel that facilitates storage, transportation and distribution;

It can be commercialized in the length desired by the costumer,

It results in a foamed, flexible, elastic and very malleable profile that is capable of suffering deformations and returning to its original shape when submitted to tightening that ensues from its application or use;

The profile has closed cells whose water absorption coefficient is lower than 0.7%, which results in great dimensional stability;

The profile is not affected by UV rays and by other wave frequency rays that are found in solar radiation, keeping its original color in any situation even after long periods of exposure;

The profile maintains its original color in any situation, even after long periods of exposure;

The profile takes painting with solvent-based paints without presenting alterations to its properties;

Due to its enormous elasticity and flexibility, the profile adapts to eventual undulations that exist in edges where the wall meets the lining or floor, as well as being able to be installed in curved surfaces such as around circular columns;

Due to the fact that it is continuous, the profile can be applied without emendations, making its installation easy and discarding operations to apply finish mass and paint which are generally used to cover emendations;

The sections in ^" angles or without angles in a continuous form, like those demanded in wall joints are facilitated and can be executed with any type of cutting tools because the profile is soft. The product shown herein presents a continuous, flexible and elastic form, hindering imperfections in the construction to be noticed, i.e. allowing a perfect finish and absorbing all construction defects once it fits into any deformation existing in the construction without showing such defect.

The finish profile is produced in an EVA-based or polyethylene mixture, or that of both of them, which makes it foamy, resulting thus in great elasticity and flexibility. This profile is produced continuously, packed in rolls and commercialized in the length the costumer desires. The composition should preferably encompass the following weight components:

EVA: 20 to 80%; or - Polyethylene: 20 to 80%; or

Mixture of EVA and polyethylene: 20 to 80%;

Calcium carbonate: 10 to 60%;

Silica: 3 to 20%;

Foaming agent: 1 to 10%; - Peroxide: 0.5 to 5%;

Resin: 1 to 10%;

Pigment: 1 to 20%.

These composition ingredients can evidently change within the proportions expressed previously, obtaining consequently the same product; due to diverse market demands, it can vary its characteristics such as hardness and density.

The profile of this invention results in diverse advantages in regard to rigid and semirigid profiles known to date:

It has low water absorption coefficient and great dimensional stability;

It is not affected by sun rays;

It keeps its original color in any situation;

It is malleable; It takes paint with solvent-based paints;

It is adaptable and dissimulates irregularities existing both on the lining and the wall;

It can be manufactured continuously and packed in rolls;

Due to the fact that it is continuous, the profile can be applied without emendations;

It can be applied easily, and its sections with angles or without angles with a continuous form so as to meet walls can be executed with any cutting tools.

The finish profiles of walls and linings can have self fixation means. According to this invention, this can be attained through a finish profile outfitted with a rear section next to its base, being fixed through a fixation profile. This fixation profile has a vertical and flat wall, and an inclined flap that penetrates the section of the profile protrudes from its inferior rim. The adhesion of the fixation profile to the wall occurs through a self-adhesive tape or any other type of adhesive glue or element that permits adhesion. The length of the flat surface of the fixation profile also serves as application draft because it must be glued on the part next to the lining.

In case the self-adhesive tape is chosen, it can be incorporated to the panel during its production or be applied by the installer at the moment the profile is fixed. Even when the fixation profile is glued with adhesive tape or by any other traditional means such as glue, screws with screw anchors can be concomitantly employed at intervals as reinforcement measures.

The adhesive tape can be substituted by glue or adhesives directly at the profile of a fixation plastic compound and also on the finish profile of EVA or polyethylene finish, or the mixture of both, on its rear, discarding the plastic profile, and gluing it directly onto the applied zone (wall, floor or half wall). Optionally, the profile c.an even have two sections wherein each of them is set next to one of the rear rims. Two support panels or only one 90° bent-angle panel can be used for this option.

Figure 5 illustrates the profile (1 ) that is destined for the lining finish which is produced with malleable material and with any type of ornamentation on its frontal side, being outfitted with a groove (11 ) next to the base on the rear side. Figure 6 shows the fixation profile (2) that has a flat vertical wall (21 ) and an inferior, inclined flap (22).

Figure 7 illustrates the fixation profile (2) onto which a self-adhesive tape (3) is preferably applied to the rear flat vertical wall (21 ). The adhesive tape (3) can be specific for that finality and be incorporated to the fixation profile (2) when manufactured, or it can be a conventional double sided tape that is applied at the moment the profile is installed (1).

Figure 8 details the application of a profile (1 ) on the wall (P), giving the finish against the lining (F).

The application process (in case the adhesive tape is chosen) foresees the following operations: - application of a self-adhesive tape (3) on the rear of the vertical wall (21 ) of the fixation profile (2); installation of the fixation profile (2) against the wall (P) in a way that its upper rim contacts the lining (F); fitting the section (11 ) of the profile (1 ) into the inclined flap (22) of the fixation profile (2).

The flexibility of the flap (22) of the panel (2) and the malleability of the profile (1 ) that exert a permanent pressure of the profile against the wall (P) and the lining (F) with no gaps left between them is the one that generates an aesthetic, adequate aspect. The elasticity and flexibility are good to absorb the imperfections of the construction and facilitate the aesthetics of the product presented onto its definitive place. By having excellent elasticity, it is possible to find the straight edges and stretches from wall to floor with angles that present the construction, or if the final consumer wishes not to have angles (just by folding the finish profile at the angles), it facilitates the union of the beginning of the strip with the end of it by solely opposing one against the other, whereby the flexibility of the material dissimulates the junction, turning it almost invisible to the human eye. Regarding the elasticity and flexibility of the EVA or polyethylene profile, or the mixture of both, it can be highlighted that with the

profile fixation system of the zone to be employed, the profile has reasonable elasticity that allows its placement on walls with determined curvatures. If these are walls with greater curvatures or columns (360°), only the finish profile with adhesive tape on its rear will be placed, without presenting any inconveniences during its application and guaranteeing a perfect finish.

Figure 9 illustrates a constructive option of the lining profile (1') which can present two sections (11'), one next to the base and the other next to the top, allowing its fixation against the wall and the lining. Figure 10 details a double fixation profile (2') that encompasses two flat and orthogonal walls (2V), wherein an inclined flap (22') can be found on the free rim of each one. In order to facilitate the installation and compensate existing irregularities on the joint of the wall with the lining, the panel (2') can present a frustrated vertex (23).

Figure 11 shows the -installation of the lining profile (1') with two sections (11') through the double fixation profile (2').

Figure 12 shows the possibility of installing the lining profile (1') by means of two independent panels (2).

Figure 13 illustrates another constructive option for the profile (10) which is flat and destined to be used as baseboard or decorative strip, being outfitted with a section (101) next to the base on the rear.

Figure 14 details the application of the flat profile (10) close to the wall (P) through the insertion of the inclined flap (22) of the fixation profile (2) on the rip (101 ), and the fixation of its vertical wall (21 ) with adhesive tape (3) on the edified wall (P). Figure 15 illustrates another constructive option for the flat profile (10'), which is outfitted with two sections (101 '), located on the rear of the profile next to the base and on the top.

Figure 16 details the positioning of the flat profile (10') close to the wall (P) through the insertion of the inclined flaps (201) of the double fixation profile (20) in the rips (101'), and the fixation of its vertical wall (202) with adhesive tape (3) on the edified wall (P).

Figures 17 and 18 illustrate an option to fix the finish profile (1, V ₁ 10 and 10') that can employ connection elements, especially screws and screw anchors (4), or nails

(5) to help fixing the support panels (2, 2' and 20). These connection elements (4 and 5) can also be employed to substitute the adhesive tape (3) or as complement of that fixation of the support panels (2, 2' and 20).

The finish profile of the lining, half wall and floor, as proposed, with self fixation means, results in the following advantages before other profiles for that finality: the installation of the profile occurs through a simple insertion in the section of the inclined flap of the fixation profile; the fixation profile is directly applied to the wall through the self-adhesive tape; the length of the fixation profile determines its positioning, for it must touch the lining; it also allows its application by non-specialized and untrained people, for it is easy to apply; the adhesive tape can be optionally substituted by glue, screws and screw anchors, or nails. This composition can still admit the non-combustible property.

For the scope of this invention, the substitution of adhesive tape (3) by glue or other adhesive to be applied manually on vertical walls (21 , 21' and 202) of the support panels (2, 2' and 20) must still be considered.
