Abstract

The present discloses a method for making small planks for wooden blinds, including a first step of cutting a tree log in a plurality of rectangular pieces, which are adequately smoothed by means of a tool for flattening before joining them by means of an adhesive in order to form a rectangular board. The rectangular board is cut into pieces in a perpendicular direction toward the longitudinal surfaces of the rectangular pieces in a plurality of small planks for a wooden blind, which are flattened again before covering them with a coating. The coated small planks for blind are finally dried in a furnace.

Description

TABLILLAS FOR WOOD BLINDS AND METHOD TO MAKE THEM FIELD OF THE INVENTION The present invention relates generally to a blind slat, and more particularly to wooden slats of the blinds and a method for making wooden slats of the blinds. BACKGROUND OF THE INVENTION The slats of the conventional Venetian blind are generally made of aluminum, plastic or wood material. The slats for wooden shutters capture the imagination of the customer in general, even if they are relatively more expensive. The slats for wooden shutters are usually made of American linden and Ra in wood in view of the fact that their wood fibers are straight and resistant to deformation. Ramin wood is a product of the tropical forest in Southeast Asia. In view of the adverse impact of excessive logging on the environment, products made from Ramin timber are banned in Europe and the United States. American linden grows in a relatively small area and is therefore difficult to obtain. It is not necessary to say, that the slats for American linden blinds are very expensive.

The conventional method for making slats for wooden shutters. It comprises a first step in which the trunk of the tree is cut into pieces, each with a width of 2 inches, one inch or 0.5 inches. In other words, there are specifications regarding the pieces of wood. In addition to the width specifications, the thickness of the pieces must be taken into consideration. For example, the thickness of the pieces that have a width of 2 inches should not be less than 3mm, considering the thickness of the pieces that have a width of 1 inch or 0.5 inches, should be not less than 2.5 mm. In view of the thickness requirements, the cost of the material can not be effectively reduced. SUMMARY OF THE INVENTION The first objective of the present invention is to provide an effective cost method for making slats for blinds, which are small in dimension and resistant to deformation. The method of the present invention comprises a first step in which the trunk of the tree is cut into a piece of rectangular shape. Each piece has smooth longitudinal surfaces and sides. The two longitudinal ends of the pieces show annual rings of the trunk of the tree. A plurality of the pieces is joined by means of an adhesive under high pressure, to form a rectangular board, which is subsequently cut from one of the longitudinal ends. thereof, in a direction perpendicular to the joining surface of the latter, in a plurality of blind slats of a predetermined thickness. The slats for blinds are covered with a coating and after drying in the oven. Each slat for blind has two rough longitudinal surfaces. Blind slats are smoothed before being covered with the siding. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1, shows a diagram of the method of the present invention. FIG. 2, shows a perspective view of a tree trunk chosen for use in the present invention. FIG. 3, shows a perspective view of a rectangular piece of the method of the present invention. FIG. 4 shows a perspective view of a rectangular board of the method of the present invention. FIG. 5 shows a perspective view of a final product of the method of the present invention. DETAILED DESCRIPTION OF THE INVENTION As shown in all the drawings that are provided herein, a method incorporated in the present invention comprises a first step in which a tree trunk 100 is selected to be used as a raw material in the method of the present invention. Only the xylem portion 101 of the tree trunk 100 is actually used in the present invention. The xylem portion 101 is formed of a heartwood 101a and a sapwood 101b. The two longitudinal ends of the trunk of the tree 100, show annual rings of the tree. The trunk of the tree 100 is cut through the longitudinal direction thereof, in a plurality of rectangular pieces 10, which are so smoothed to have two smooth longitudinal surfaces 11, two smooth longitudinal sides 12, and two smooth longitudinal ends 13, which show a profile of annual rings. The longitudinal surfaces 11 of a plurality of rectangular pieces 10 are coated with an adhesive before the rectangular pieces 10 are randomly attached under pressure to form a rectangular board 20, as shown in FIG. 4. Inasmuch as the rectangular board 20 is formed of a plurality of the rectangular pieces 10, which are joined at random, the two longitudinal ends of the rectangular board are formed of a plurality of the longitudinal ends 13 whose fiber grains are they are arranged in the opposite direction to provide optimum resistance to deformation. The rectangular board 20, is split from the longitudinal end 13, in a direction perpendicular to the joining surface of each piece 10, so that the rectangular board 20 is cut into a plurality of strips for blinds 30, where each has a thickness W, as shown in FIG. 5. The blinds strips 30 are suitably smoothed and provided with two end-to-end holes 31, which are located in proximity of the two longitudinal ends of the shutter slats 30, to receive the blind's laces ... Blind slats 30 are covered at the end with a coating and then dried in an oven. The slats for blind 30 are smoothed before being covered with the coating. The method of the present invention has advantages over conventional methods. In the process of forming the rectangular board 20 of the present invention, a plurality of rectangular pieces 10 are adhered randomly, so that the wood fibers are not arranged in a linear fashion and that the grains of the fibers of the longitudinal ends 13 of the pieces 10, are arranged in the opposite direction, so as to result in the effect of voltage cancellation. As a result, blind slats made by the method of the present invention are relatively more resistant to deformation. In addition, the blind slats of the present invention are provided with a decorative effect of natural wood grains. In addition, the thickness requirement of the blind slats 30, is relatively flexible, so that the thickness of the blind slats is less than 2.1 mm in relation to the width of the blind slats, which is about 2 inches , and that the thickness of slatted slats with a width of approximately 0.5 inches, is less than 1.6 mm. As a result, the cost of the material of the method of the present invention is relatively lower, if it is. compare with conventional methods. It should be noted here that the trunk of the tree 100 of the method of the present invention is obtained from the spruce, pine and other trees having grains in the form of a net or corrugated grains.
